django-tagulous's Issues

Instructions for migration to tagulous are wrong

It looks like the instructions for migrating to tagulous don't work correctly - in step 2 I don't think taggit (or tagging) is going to work in the data migration. I can't test this at the moment, but if that's the case we need to collect the tags directly, using the generic relations.

I had thought I'd tested that bit thoroughly at one point, so not sure how that got through - but because it's only in the docs there are no automated tests. Sorry! It should be possible to add some though.

I'm travelling at the moment, so it may take a couple of weeks for me to fix (patches welcome of course) - I'll update the docs in the meantime.

ValueError: Could not find manager CastTaggedUserManager in tagulous.models.tagged.

I'm trying to set tag tree models and I get the error
ValueError: Could not find manager CastTaggedUserManager in tagulous.models.tagged.

The TagTreeModel is:

class BusinessPhase(tagulous.models.TagTreeModel):
    class TagMeta:
        # Tag options
        force_lowercase = True

And the model is:

class User(AbstractUser):
    business_choices = tagulous.models.TagField(to=BusinessPhase)

Case sensitivity bug in SQL query when working with PostGreSQL

Hi,

I just ran into another issue where the table name is added to the SQL query without quoting.
This causes PostGreSQL to throw fatal database errors if the table names have uppercase letters since PostGres will automatically lowercase unquoted table names. I'm working on a legacy Django project that uses camelcase in the app folder names. Simply renaming them is currently no solution as there seems to be no clean way to migrate. Even simply renaming the name property in the AppConfig seems to be a show stopper. Django itself handles this nicely (hence the table names with mixed case in the database).

A quick and simple way to resolve this is by simply adding double quotes around the table name in the SQL template as found in models.py on line 83:

        # Build SQL
        template = (
            '%(floor)s((count*%(upper)d)/'
            '(SELECT MAX(count) FROM "%(table)s")'  # <-- added quotes
            ')+%(lower)d'
        )

Just like the other issue I reported today, these seem like quick fixes imo (but I'm no expert so I could be wrong).

Maybe I'll even dare to fork and create a PR (despite me being a total python noob).

Kind regards,

Erik

Breaks with other Django Select2 libraries

I've tried both django-easy-select2 and django-select2 and this library breaks with both of them.
I cant get tagulous to work with any other admin select2 widgets. Compatibility would be nice.

For what its worth, as much as I like Tagulous more, this has forced me to abandon using Tagulous on a brand new project and switch to another library with the hope I can migrate to Tagulous in future.

Problem using tagulous with 2 django instances sharing database

I have set up an app with tagulous which works fine. However, I now have another app in a completely different django instance that has read-only access to the first apps database. This is so statistical data from the first app can be viewed in the second app.

Trouble is I can't get the second app to work at all when the code from the first app with the tagulous models is added in. I just get:
ValueError: Cannot set tag options on explicit tag model <class 'action_tool.models.ActionToolTreeTag'>

Any ./manage.py command returns the error.

In the first app I have:

class ActionToolTreeTag(TagTreeModel):
    class TagMeta:
        protected = True

class Action(models.Model):
    primary_tags = TagField(to=ActionToolTreeTag, blank=True, null=True, related_name='primary')
    secondary_tags = TagField(to=ActionToolTreeTag, blank=True, null=True, related_name='secondary')

That all works ok in the first app. The first app is installed in the second django instance and has a database router routing it to the first app db.

Any pointers appreciated!

Thanks!

Restrict Creation of new Tags

I did not see an easy option to disallow the user to create new items, but only select existing ones.

Instructions missing for rendering form

Documentation seems to be missing notes on how to include the form.media and the need to run collectstatic (or at least if it's there it's not obvious).

As noted in #55 and at https://vevurka.github.io/dsp17/python/django/tagging/

Why is 'through' in TagField.forbidden_fields?

Thanks for another tagging library and i am not being sarcastic!

"Based on ForeignKey and ManyToManyField, so it's easy to query" is a big selling point for me, so I was surprised to see, that giving a custom through model is not possible.

When I remove the code "forbidding" that, all I need still seems to work. What is the reason behind forbidding custom through models? What side-effects should I be aware of when circumventing the check?

Django 2.0 compatibility

Now that it works with 1.11, how about 2.0? Any stopping issues?

Example project doesn't run (missing migration and failed migration after making my own).

Following the procedures associated with starting up the example project, I've run into several blocking problems.

First, to establish context that I'm starting in a clean virtualenv:

I've deleted the longer exception because the fundamental problem is the missing table. So I figured the problem was just a missing migration that didn't get committed, so I'd recreate:

And it's all gone to crap. Keep in mind, this is the example project, using the build procedure specified in the documentation at: https://github.com/radiac/django-tagulous/tree/master/example

supports Django 1.11

hi, does not support the new django 1.11 version?
i have this problem:

ERRORS:
core._Tagulous_Ideas_tags: (models.E023) The model name '_Tagulous_Ideas_tags' cannot start or end with an underscore as it collides with the query lookup syntax.
The command "python manage.py migrate" failed and exited with 1 during .

thanks

TagRelatedManagerMixin causing extra database queries

When I loop over a list of objects that have a tag field, the reload method in TagRelatedManagerMixin is triggering a database lookup for every object.

Example of the query:


SELECT "games_location"."id", "games_location"."name", "games_location"."slug", "games_location"."count", "games_location"."protected", "games_location"."title", "games_location"."content" FROM "games_location" INNER JOIN "games_game_location" ON ("games_location"."id" = "games_game_location"."location_id") WHERE"games_game_location"."game_id" = '8'  Duplicated 7 times. | 4.349717268377556% | 0.50 | SelExpl

...

E:\vm\venv\churchworthy\lib\site-packages\tagulous\models/managers.py in reload(486)   
self.tags = list(self.all())

Because self.all() is being forced into a list, it's executing the query for each Game object. Normally I would use prefetch_related() to cut down on database calls but this is preventing it from actually helping. I'm not totally clear on what the reload method does for me when I'm just querying tags and not saving anything.

Fatal division by zero (ORM) error when no tagged items exist

Hi,

I noticed I kept getting a division by zero error from the Django ORM when trying to fetch the tags with weights if no tagged items exist. The error comes from the SQL query and is reproducible on the database level.

tags = SomeModel.tags.tag_model.objects.weight()

throws: django.db.utils.DataError: division by zero
try - catch doesn't seem to help either

SELECT (FLOOR((count*5)/(SELECT MAX(count)

Simply adding one tagged item solves this issue.
Rewriting the query as follows solves this issue as well (as dividing by NULL yields NULL), returning weight: NULL if no tagged items exist

SELECT (FLOOR((count*5)/(SELECT NULLIF(MAX(count), 0)

I'm just a Django / Python beginner so I don't really know how to address this issue properly. As far as I can tell, NULLIF seems standard SQL syntax and does work on my local PGSQL server.

Kind regards,

Erik

Look Up with Q object

I am trying to filter using tags created with taguluous. However, when using the Q object to filter the tags, it comes up with this error

Exception Value: invalid literal for int() with base 10: '(my tag)'

where the line of code the error appears is in :
recipe_list= RecipePage.objects.filter(Q(recipeName__icontains = word) | **Q(tags = word)**)

In my models.py:

class RecipePage(models.Model):
    user = models.ForeignKey(CustomUser)
    recipeName = models.CharField(max_length=100)
    tags = TagField(
        force_lowercase=True,
        max_count=5,
    )

Let me know if there's another or better way to use multiple arguments to filter my queryset!

Thank you!

Object view in admin returns "object of type 'FakeQuerySet' has no len()"

Hi,

I have a very simple model and tried to implement tagulous. It all works fine except that I cannot access an object with tags within the Admin. It refers to both django-admin code as well as tagulous, that is why I am posting it here.

admin widget in django template

Hi again,

I have a tags = TagField( autocomplete_view='story_tags_autocomplete') field in my model.

I want to implement this widget - from the admin, in a user facing page

After having looked at the example project and the docs, I cannot figure out how to code the template. I have also looked at the select2.js docs. An ordinary jquery ajax call gives me the tags but from there I am stuck.

Can you add this as an example to the example? It would look nice

Thanks

Prevent user creation of new tags

We would like to set up our tag field such that only existing tags (defined by staff) can be selected. We do not want users to be able to add new tags. Is this possible with this library? I've read through the documentation and it's unclear to me whether this library actually supports it.

Thanks!

Max length for tree path

The max slug length of 255 seems reasonable for tag fields, but that could quickly lead to some very long paths in tag trees. If we take 2000 chars as the upper URL limit, we can set a default of 1900 to allow for most options, and document that the start of a path URL can only safely be 100 chars long.

The main problem with this is that paths are auto-generated, so we have to manage this automatically. I suggest that once a path gets to eg 500 characters its no longer human-readable anyway, so instead of using tag slugs in the path, we use tag ids (for the children of the first tag to break the 500 char limit).

These limits will be configurable as site-wide settings. Upgrade instructions will need to warn of the change.

Users may accidentally create a blank tag when trying to clear a field.

It is not obvious that users should use the delete key to clear a SingleTagField. Users sometimes try to erase the field with the space bar, which makes it appear blank, thus creating a tag of " ". I have had to work around this by strip() and converting "" to None in my form's clean method. If there is no case where " " is a useful tag, this could be built in to the library.

In admin, AttributeError: type object '<model>' has no attribute 'tag_options'

Hello

I have just installed django-tagulous and everything is working fine until I have this line:
autocomplete_view='story_tags_autocomplete'

I have tested it with and without running migrations on django 11

Here is my model:

class Story(Model):
    ...
    tags = TagField(
        autocomplete_view='story_tags_autocomplete'
    )

Here is the relevant urls.py lines:

from tagulous.views import autocomplete

url(r'^story/tags/autocomplete/', autocomplete, {'tag_model': Story}, name='story_tags_autocomplete'),

Here is a picture of what happens in the admin:

Tagulous and django-model-utils FieldTracker NoneType comparison

We use Tagulous as well as Django Model Utils's FieldTracker

FieldTracker checks which fields have changed as a model instance is saved, which we use for revision logging. FieldTracker offers a has_changed method to see if a field has changed in a save() operation. That function compares the field instance before and after a model instance save() operation. However, for a newly created model instance, the first instance of the field will be None. So has_changed compares None to a new Tag instance. Tagulous _eq function (in class BaseTagRelatedManager(object) in django-tagulous/tagulous/models/managers.py) doesn't account for this case, which raises a TypeError 'NoneType' object is not iterable in other_tags = [six.text_type(tag).lower() for tag in other].

Would be great if we can add a check in there for this case so it plays together more nicely with other Django apps?

Abstract Base Class Support

I wasn't able to add a Tag field to an Abstract Base Class model so that all child models would have tags.

Django 2.1 incompatibility.

Hi,

I have updated the version of my project for django 2.1, and I am having problem to render forms, I get error :

TypeError: render () got an unexpected keyword argument 'renderer'

Django 2.1 release says, Feature removed in 2.1:

"Support for Widget.render ( ) methods without the renderer argument is removed. "

if it's helpful, I've managed to solve it, modifying the method "render" of the class "TagWidgetBase", I have added "renderer=None" in tagulous / forms.py:

def render (self, name, value, attrs = {}, renderer=None):

if this solution is correct to fix this problem, you can accept my pr?

thanks.

Save tags in the model admin

Hi to everyone. I would like to save a list og tags to the model overriding the save_model() en the Django Admin.

I have this:

    def save_model(self, request, obj, form, change):
        obj.tags = a_list_of_tags
        obj.save()
        super(VideoAdmin, self).save_model(request, obj, form, change)

But it don't works. I'm doing bad?

Wrong error (IndexError) while trying to save a Tag without a name

Hi,
I've run accross a small problem while trying to create a Tag. I've defined my own Tag model as such :

class Tag(TagTreeModel):
    
    class TagMeta:
        protect_all = True

Then if I try to save a tag without a name I get an IndexError while I would expect and IntegrityError:

>>> Tag().save()
Traceback (most recent call last):
  File "<input>", line 1, in <module>
    Tag().save()
  File "/srv/http/venv/lib/python2.7/site-packages/tagulous/models/models.py", line 711, in save
    self.label = parts[-1]
IndexError: list index out of range

This is not a big issue but if I was trying to catch that error I would not expect this one since Tag.name is a non null field.

AttributeError: 'CastTaggedQuerySet' object has no attribute 'save'

Hi,

Thanks for your app, I have managed to use it well so far.
But now I am facing the following problem; if I try to set a list to the attribute tags of my model, only the last will be related with the holding model.

I have an archive model with a tag fild.

archive.__setattr__('tags', extracted_tags[:5]) *mode code* archive.save()

Where extracted_tags is a list of strings, comma separated.

It saves the tags, and i can see all of them at django admin as well on my app, but only the last of them is really related to the model.

Imagine extracted tags are "ec2" , "shard", "amazon", "aws" and "mongodb".

Doing queries like the following:
Archive.objects.filter(tags="ec2")
returns nothing []
But:

Archive.objects.filter(tags="mongodb")
[<Archive: AWS_NoSQL_MongoDB>

Strange because doing:

Archive.tags.tag_model.objects.all() gives:

[<_Tagulous_Archive_tags: amazon web services>, <_Tagulous_Archive_tags: aws>, <_Tagulous_Archive_tags: ebs>, <_Tagulous_Archive_tags: ec2>, <_Tagulous_Archive_tags: mongodb>

But asking for :
Archive.tags.tag_model.objects.filter(name="mongodb")
return:

[<_Tagulous_Archive_tags: mongodb>]
But asking for:

Archive.tags.tag_model.objects.filter(name="shard")
[]

Very rare....

And so on for the other 3 properties. So only the last tagged inserted is really related to the model, despite the fact all of them appear at the admin and in my views under that "archive" model.

The error on the title of this issue is because whenever I open shell_plus and try to save an archive, even without specifying tags, it says i cant save because is a CastTaggedQuerySet, eventhough i just do:

a = Archive.objects.filter(title="AWS_NoSQL_MongoDB")

In the other hand, when i check those tags in postgres, int he table appname__tagulous_archive_tags , the table appnamea_archive_tags, etc, all is well related, and seems to be OK.

Following above example: "shard" is id 63 related with archive_id 27, so it looks fine but somehow, something is not working properly.

Could you help me please?
Thanks

Need help with the UI

I am trying to find the way to have the UI changing effect when I press enter after inputting a tag (which also comes with a cross to delete the tag) instead of typing comma. I saw that implemented in the example but not sure how is it done. My model and form are as below:

class UserProfile(models.Model):
    ..........
    subjectTags = tagulous.models.TagField(to=SubjectTags)


class CompleteProfileCTutorForm(forms.ModelForm):
    phone_number = forms.CharField(max_length = 12)
    bio = forms.CharField(max_length = 500, widget=forms.Textarea)
    avatar = forms.ImageField(required=False)
    subjectTags = tagulous.models.TagField()

    class Meta:
        model = UserProfile
        fields = [
                     'phone_number',
                    'bio',
                    'subjectTags',
                    'avatar',
                 ]
        exclude = ('user',)

Thanks for your help in advance.

Tags are not saved when subclassing PolymorphicModel

I have inherited model (through PolymorphicModel https://github.com/chrisglass/django_polymorphic):

from django.db import models
from polymorphic import PolymorphicModel
from tagulous.models import TagField

class Event(PolymorphicModel):
    name = models.CharField(max_length=40, blank=False, null=False)
    datetime = models.DateTimeField()
    tags = TagField()

class UpdateUpload(Event):
    destination = models.CharField(max_length=20, default=None)
    product = models.CharField(max_length=30, default=None)
    subproduct = models.CharField(max_length=20, default=None, blank=True, null=True)

When I use the Django-admin, I can set the tags for the parent model "Event" and for the model "UpdateUpload".
But when I try to set the tags 'manually' in the child model (see below), the tags are not set / changed:

>>> ins = UpdateUpload.objects.get(pk=253)
>>> ins
<UpdateUpload: 20151023-test-1.7.1-release>
>>> ins.tags
<django.utils.deprecation.TagRelatedManager object at 0x063305F0>
>>> ins.tags.all()
[<_Tagulous_Event_tags: test>, <_Tagulous_Event_tags: release>, <_Tagulous_Event_tags: test>]
>>> ins.tags = ['test1', 'test2']
>>> ins.save()
>>> ins.tags.all()
[<_Tagulous_Event_tags: test>, <_Tagulous_Event_tags: release>, <_Tagulous_Event_tags: test>]
>>> ins.tags = 'test1, test2'
>>> ins.save()
>>> ins.tags.all()
[<_Tagulous_Event_tags: test>, <_Tagulous_Event_tags: release>, <_Tagulous_Event_tags: test>]

With the parent model, it is working:

>>> inse = Event(name='testevent', datetime=datetime.now())
>>> inse
<Event: testevent>
>>> inse.tags = ['test', 'test1']
>>> inse.save()
>>> inse
<Event: testevent>
>>> inse.tags.all()
[<_Tagulous_Event_tags: test>, <_Tagulous_Event_tags: test1>]

I can't figure out why. It works on my dev server but it won't work on my Ubuntu server (digital ocean). I've attached my requirements. Also note that I've switched to django version 1.10 as it says in Tagulous documentation that is the newest supported version. Also note that I am using Python 2.7 on my Ubuntu server but using python 34 on my development server. That is the only difference I can see.

Max length for slug field

It would be better if the slug max length is a setting, not hardcoded to 255. Slugifier should also take this into account.

Upgrade to Select2 version 4

Can we upgrade select2 to version 4?
It looks as though it now supports defining a list of characters to stop parsing on eliminating some of the need for your monkeypatching.

I tried to modify your adapter code, but the significant changes in version 4 of select2 left me completely unable to work out how to update your adapter.

Pasting 3 tags into a TagField crashes browser

Example: paste, these, strings

TagField and django tastypie POST resource is not saving m2m relationship.

Actually, I'm trying to save a tastypie model resource which contains a TagField from django-tagulous

Here are my model, and resources:

# models.py
class SimpleModel(models.Model):
    topics = tagulous.models.TagField()
    title = models.CharField(max_length=100)


# resources.py
class TopicResource(ModelResource):
    class Meta:
        queryset = SimpleModel.topics.tag_model.objects.all()
        authentication = Authentication()
        authorization = Authorization()


class SimpleModelResource(ModelResource):
    tags = fields.ToManyField(TopicResource, attribute='topics', full=True, null=True)

    class Meta:
        queryset = SimpleModel.objects.all()
        authentication = Authentication()
        authorization = Authorization()

the curl part:

curl --request POST --dump-header - --header 'Content-Type: application/json' --data '{"tags": ["/api/v1/topic/1/"], "title": "A bad dream"}' localhost:8000/api/v1/simplemodel/

The shell doesn't return any error, however, the tags are not associated with the new object.

By overriding the ModelResource save_m2m method, before the super call the tag object is present (print bundle.data['tags']), then in the super(SimpleModelResource, self).save_m2m(bundle) tastypie looks for the related manager associated with the tags field, the related_mngr is returned but when it is evaluated using: if not related_mngr it evaluates to True skiping the m2m association.

I'm sorry if it isn't an issue for this repository, I'm was not sure, and maybe it must be posted in the django-tastypie repository.

Deserialization exception for model with ManyToOneRel

I'm using Django 1.8.7 and have a model with several tagulous fields and with ForeignKeys pointing to it from other models.

When I serialize it (Article) like so:
data = serializers.serialize("xml", Article.objects.published()[:1])

And then deserialize it (test code):

for obj in serializers.deserialize("xml", data):
    type(obj.object)

This exception is thrown:


File " ... /tagulous/models/tagged.py", line 414, in _detag_to_serializable
    clone_field.contribute_to_class(FakeTaggedModel, field.name)
AttributeError: 'ManyToOneRel' object has no attribute 'contribute_to_class

If I comment out all references to Article in models that use it as a ForeignKey, the deserialization proceeds without throwing an Exception. It is when the ManyToOneRel fields are encountered that the exception occurs because these do not appear to have "contribute_to_class" attributes.

I can supply more information upon request, but the model is large and I'm hoping this is enough to reproduce the error. (Exception trace below.)

Thanks (I'm otherwise finding tagulous excellent).

Set TagTree parent without slashes

I would like set the parent of a tag without slashes, instead with a select box. For example dont use this:

And use it:

Select2 widget sticks on searching when pasting multiple tags

Recreate: paste into example skills one, two, java. It sticks on "searching", even though there are matching results.

If multiple tags have been pasted, it is likely complete, so should not search anyway.

Example usage ajax autocorrect incorrect

In the url definition, {'tag_model': Person}, should be {'tag_model': Person.skills.tag_model}

Can not add single character parent tag.

Django 1.11.3

        space_delimiter=False,
        tree=True,
        related_name='medias',
        blank=True
    )

Looks like utils.split_tree_name returns an empty list.

Support: Using Tagulous in a Form (not ModelForm)

Maybe I am too dense, but I went over the documentation a few times and I cannot find how to use Tagulous in a regular Form that is not a ModelForm. Maybe I am missing something.

We are trying to have a search view that can be filtered by tag but cannot figure out how to set it up so Tagulous autocompletes from the right field in the right model. Anyone can point us in the right direction?

I followed the documentation at http://radiac.net/projects/django-tagulous/documentation/usage/#example_tag_trees but

Support for newer version of django (1.11.6)

I am currently using django 1.11.6, and when I tried to use tagulous, it says module object has no attributes 'models'. Is it because my version is too new? I have followed the steps of installation. If so, will there be support for it soon?

Thank you very much for your help in advance.

'list' object has no attribute 'pk'

When using with Django REST Framework 3+ and specifying the model property with tagulous.models.TagField a POST/PUT request via the Browsable API throws below error:

AttributeError at /api/calendar-item/1/
'list' object has no attribute 'pk'
/usr/local/lib/python3.6/site-packages/tagulous/models/managers.py in _ensure_tags_in_db, line 522

The DRF handles ManyToMany fields fine via API, by allowing requests to assign the related join to the entity being created/updated.

Can you add a seralizer extension method to allow POST/PUT requests to allow posting of the multiple "tag" primary keys to be saved against related entity; instead of expecting CSV string.

TagRelatedManager indexing support

Something I would like is indexing support for the TagRelatedManager. This is for a case where a slug is passed to a view, and after grabbing the correct tags based on the slug, I want to also get the name of that respective tag. Like this

lang_name = Game.approved.filter(language__slug=lang_slug).first().language[lang_slug].name

Can not add chinese tags on chrome or safari?

It works on IE.
But when I type chinese words on chrome or safari, it keeps only the English letters in the inputbox .
