MongoEngine support for django-tastypie.
License: Other
This Django application provides MongoEngine support for django-tastypie.
This project is unmaintained. If anyone wants to step up and take over maintenance, please open an issue.
There is a problem when using PATCH if there is related field that has full=True parameter.
I'm no software licencing expert however I noticed that this project uses the AGPLv3 licence.
This summary of the AGPLv3 licence says you can't
In layman's terms that means that people can't use django-tastypie-mongoengine if they don't share the source of their Django project. I can't use this project due to that restriction, if that's what you intended that's fine (say so and close this issue), if you didn't intend that please change the licence to a BSD or similar (such as Django itself uses) so that restriction is lifted.
I am trying to send date_time from jQuery post to our server we are using mongoDB as backend and using django_tastypie_mongoengine for posting so far i have tried putting date="2010-11-10T03:07:43" and also date="2013-05-21T02:17:55.544000" in my jQuery but it is failing everytime.
I want to know the exact syntax of sending date

API for accessing lists of document references as subresources. Currently only access to lists of embedded documents is possible.
Hello,
I don't know if the issue is related to mongoengine or tastypie, but I have a problem with a PUT.
I use angularjs and RESTangular to create this PUT, but I reproduced by writing my PUT request manually.
When I try to save my user (https://github.com/Seraf/LISA/blob/angularjs/lisa/server/web/weblisa/api/accounts.py#L22), it throw me a :
{"error_message": "Could not save document (Mod on _id not allowed)", "traceback": "Traceback (most recent call last):

My user is a custom class : https://github.com/Seraf/LISA/blob/angularjs/lisa/server/web/interface/models.py#L15
So, digging a little bit to understand why it doesn't work, I tried with my plugin resource :
https://github.com/Seraf/LISA/blob/angularjs/lisa/server/web/manageplugins/api.py#L14
And it worked.
So I tried to see why it detected an _id field as changed on my user resource, and not my plugin.

One thing I noticed is that, in windows, the using mongoengine if I save collections, I get the following structure, for example.
{"_types" : [ "Test" ], "f1" : "Ranjith", "_cls" : "Test" }
But with the above mentioned configuration, I'm just getting:
{"f1": "Ranjith"}
Any help is highly appreciated as it's the project demo day..
Thanks
Support for embedded list field subresources set processing.
If an API client sends an invalid request to the API server, the server should return a 4xx response rather than a 5xx response.
The dispatch() method on MongoEngineResource raises AssertionError when testing the request method. If dispatch() was to raise tastypie_exceptions.BadRequest rather than AssertionError, then tastypie will return an HTTP 400 to the client rather than an HTTP 500.
In the 0.4.2 version of tastypie_mongoengine, the AssertionError exceptions are raised in the following places:
tastypie_mongoengine/resources.py:373
tastypie_mongoengine/resources.py:376
Mongoengine's SequenceField is not mentioned in
MongoEngineListResource objects do not check authorization for any changes (create, update, delete) prior to performing them. In obj_update for example https://github.com/wlanslovenija/django-tastypie-mongoengine/blob/master/tastypie_mongoengine/resources.py#L854 the change is made and saved without ever checking in for authorization to make the change. The only permissions enforced here are read_* checks when getting the parent/containing Document.
Hi,
First of all, thanks thanks to every contributor on this project, it is very useful when playing with tastypie !

Thanks in advance for spending your time on this.
Leo.
For update actions MongoEngineResource triggers an authorization check twice.
First time is:
https://github.com/wlanslovenija/django-tastypie-mongoengine/blob/master/tastypie_mongoengine/resources.py#L559
After that it calls tastypie's .save() function which again checks the authorization
It's possible to override method using X-HTTP-Method-Override header in django-tastypie.
The problem is that POST request with X-HTTP-Method-Override: DELETE fails on assertion in dispatcher.
Hi,
I am implementing the RESTfull server where I have to serve rest services to different type of clients so in order to keep it as stateless service I want to use token based authentication where I will return a bearer token on login and then I wanna use this token in Authorization Header to authorize other rest services.
I tried to googling it but could not found any prefect solution.
Thanks,
AbdulWahid

Hello,
First here is the code :
API resources : https://github.com/Seraf/LISA/blob/6cf8d2ea7928c91231a30ef0734da81ac8d8fdbe/LISA-Engine/web/interface/api.py
Models used :
These models have a referencefield to a user (as a user have a Workspace)
I'm trying to create a Workspace resource by post method with Tastypie (using the swagger ui).
It shouldn't be too complicated as I have only a simple model with a : user = ReferenceField(User, required=True)
The problem is I can't pass this reference from tastypie :
Using the id of my user object :
{
"user": "51cade8246e1fa47c14ddfcc",
"name": "Dashboard"
}
Result in :
{
"error": [
"ValidationError (Workspace:None) (A ReferenceField only accepts DBRef or documents: ['user'])"
]
}
When I use the resource_uri :
{
"user": "/api/v1/user/51cade8246e1fa47c14ddfcc/",
"name": "Dashboard"
}
Same problem :
{
"error": [
"ValidationError (Workspace:None) (A ReferenceField only accepts DBRef or documents: ['user'])"
]
}
I don't know if it's related to mongoengine, tastypie, or the both .. So sorry, I post my issue here. Hope you will have some free time to help me.
Thanks a lot for tastypie-mongoengine !
With django-tastypie-mongoengine 0.4 and django-tastypie 0.9.14, I am trying to expose the schema for a resource created from a DynamicEmbeddedDocument. This used to work in 0.3+0.9.11 but now throws an AttributeError: 'ListQuerySet' object has no attribute '_document' error, presumably because the resource returns a ListQuerySet object that doesn't get converted to a MongoEngineListResource by the EmbeddedListField.
For example, if I have the resources:
class EmbeddedFooResource(MongoEngineResource):
...
class Meta:
object_class = Foo #this is a DynamicEmbeddedDocument
resource_name = 'foo'
class BarResource(MongoEngineResource):
foo = EmbeddedListField('EmbeddedFooResource')
...
class Meta:
queryset = Bar.objects.all()
resource_name = 'bar'
How would I get the schema for EmbeddedFooResource? api/v1/foo/schema/ isn't working for me and api/v1/bar/<_id>/1/foo/schema/ isn't possible. Thanks!

Help me please.
I'm trying to setup a resource with EmbeddedListField, and it fails to Authenticate user to access the individual items.
Here is my example:
class FieldDefinitionResource(MongoEngineResource):
class Meta:
object_class = documents.FieldDefinition
authentication = ApiKeyAuthentication()
authorization = StaffAuthorization()
class SectionResource(MongoEngineResource):
fields = EmbeddedListField(attribute='fields',
of='myproj.api.resources.FieldDefinitionResource',
full=True, null=True)
class Meta:
object_class = documents.Section
authentication = ApiKeyAuthentication()
authorization = StaffAuthorization()
StaffAuthorization() allows performing all actions (read, update, create, delete on both list and detail) to active users, who are is_staff or is_superuser
This request
/api/v1/section/52adcdbc02c8f1078ea68f63/?format=json&username=beta&api_key=b924d14ff71d27509a25f0d779ec45db83158199
works perfectly fine, displaying the list of fields and their resource_uri's
But this one:
/api/v1/section/52adcdbc02c8f1078ea68f63/fields/0/?format=json&username=beta&api_key=b924d14ff71d27509a25f0d779ec45db83158199
fails with 401
This happens with any of the requests: GET, PATCH, POST, etc.
After switching authorization off (i.e. authorization = Authorization()), everything works fine in both cases: /section/ and /section/section_pk/fields/field_index. Also, all the requests work fine for SectionResource with authorization on, so it's not the problem with custom StaffAuthorization.
Debugging showed that in the method read_detail of StaffAuthorization the bundle.request.user is AnonymousUser - so, it skips Authentication entirely.

I'm not sure why the check (https://github.com/mitar/django-tastypie-mongoengine/blob/master/tastypie_mongoengine/fields.py#L259) checks for bundle.obj.pk, but in the case of an embedded document it's clearly not correct.

I can see reference field, embedded document field, listfield of embedded document field, etc. but didn't see FileField. Is it supported?
Hi;
I am trying to update a resoure. My data is:
{
"tokens" : {
"first_token": "xasdadjasdh22939123"
}
}
I am doing a PUT request and getting 204. But nothing happens.
Any example how people do that?
We should add support for the ApiAuthentication by adding a mongoengine model that overrides this (from tastypie/models.py):
class ApiKey(models.Model):
user = models.OneToOneField(User, related_name='api_key')
key = models.CharField(max_length=256, blank=True, default='')
created = models.DateTimeField(default=datetime.datetime.now)
def __unicode__(self):
return u"%s for %s" % (self.key, self.user)
def save(self, *args, **kwargs):
if not self.key:
self.key = self.generate_key()
return super(ApiKey, self).save(*args, **kwargs)
def generate_key(self):
# Get a random UUID.
new_uuid = uuid.uuid4()
# Hmac that beast.
return hmac.new(str(new_uuid), digestmod=sha1).hexdigest() Then it will be possible to use a specialized version of the following hook to authenticate against a mongoengine.django.auth.User object :
def create_api_key(sender, **kwargs):
"""
A signal for hooking up automatic ``ApiKey`` creation.
"""
if kwargs.get('created') is True:
ApiKey.objects.create(user=kwargs.get('instance')) Make python setup.py test run tests. Also document test running.
Furthermore, ./manage.py test in tests does not work.

Hi,
I'm running into an issue with obj_create in resources.py throwing an exception. It happens after an upgrade while posting to the simplest model I can create. I really expect this is a versioning problem and before doing a pull request, wondered if you know something right off that might be the answer.
I have been successfully running the following:
python 2.7
django-tastypie==0.9.11
django-tastypie-mongoengine==0.2.1
mongoengine==0.6.16
My app has one document model which I have been POSTing and GETing from with no problem. Today I tried adding PUT and PATCH for the model, and received "not implemented" messages in the return data. I thought that (and I could be wrong) that tastypie did not implement put and/or patch in 0.9.11. So, I upgraded my packages to:
django-tastypie==0.9.12
django-tastypie-mongoengine==0.3
mongoengine==0.6.16
After this point, doing a post on my original model resulted in:
updated_bundle = self.obj_create(bundle, *_self.remove_api_resource_names(kwargs)) File "/Users/guerry/Envs/adfreeq/lib/python2.7/site-packages/tastypie_mongoengine/resources.py", line 504, in obj_create\n return super(MongoEngineResource, self).obj_create(bundle, request, *_kwargs)\n\nTypeError: obj_create() takes exactly 2 arguments (3 given)
I created a very simple model and resource (below) and got the same result.
class TestRecord(Document):
my_text = StringField(max_length='10')
class TestRecordResource(resources.MongoEngineResource):
class Meta:
queryset = TestRecord.objects.all()
resource_name = 'record'
allowed_methods = ('post', 'get')
curl "http://localhost:8000/api/v1/record/" --dump-header - -H "Content-Type: application/json" -X POST --data '{ "my_text": "cool text" }'
Any thoughts?
When my resource class is polymorphic, the /schema url fails, something like this:
class OtherArticle(MongoEngineResource):
class Meta:
queryset = models.OtherArticle.objects.all()
publication = fields.ReferenceField(to='datahub.api.PublicationResource',
attribute='publication', full=True, null=True)
class Article(MongoEngineResource):
class Meta:
queryset = models.Article.objects.all()
polymorphic = {
'article': 'self',
'other': OtherArticle,
}
publication = fields.ReferenceField(to='datahub.api.PublicationResource',
attribute='publication', full=True, null=True) The schema for the article resource returns:
Reverse for 'api_get_schema' with arguments '()' and keyword arguments '{'api_name': None, 'resource_name': 'publications'}' not found
When I remove the polymorphic attribute, it works as expected.
EmbeddedListField should probably allow empty list to be stored even with null=False?
Example from docs:
from tastypie import authorization
from tastypie_mongoengine import resources
from test_app import documents
class PersonResource(resources.MongoEngineResource):
class Meta:
queryset = documents.Person.objects.all()
allowed_methods = ('get', 'post', 'put', 'delete')
authorization = authorization.Authorization()
doesn't work with python3:
def __new__(cls, name, bases, attrs):
meta = attrs.get('Meta')
if meta and hasattr(meta, 'queryset'):
> setattr(meta, 'object_class', meta.queryset.model)
E AttributeError: 'QuerySet' object has no attribute 'model'
objects.all() doesn't have model attribute that is required here:
https://github.com/toastdriven/django-tastypie/blob/master/tastypie/resources.py#L1691
Hi mitar,
Just to know, is there any reason why EmbeddedDocumentFields init arguments are so limited ?
cf. fields.py#L79
I've just quickly tested with readonly, which I need, and it works -in my case- fine. blank should also be interesting.
class UserResource(resources.MongoEngineResource):
class Meta:
queryset = models.User.objects.all()
allowed_methods = ('get', 'post', 'put', 'delete')
authorization = authorization.Authorization()
resource_name = "user"
Here is the "/api/v1/user/" response:
{
"meta": {
"limit": 20,
"next": null,
"offset": 0,
"previous": null,
"total_count": 1
},
"objects": [
{
"bio": "I'm a computer engineer",
"contact": {
"twitter": "xsadasda"
},
"email": "[email protected]",
"first_name": "Burak",
"gender": "M",
"home_city": null,
"id": "50796e9da5e97c571445d8be",
"last_name": "Kılıç",
"outh_tokens": {},
"photo": null,
"resource_uri": "/api/v1/user/50796e9da5e97c571445d8be"
}
]
}
When I make "/api/v1/user/50796e9da5e97c571445d8be" , it gives 404 not found. Is something wrong?

Hi !
I've got this schema :
class PipeResource(resources.MongoEngineResource):
exporters = EmbeddedListField(of='api.resources.EmbeddedExporterListResource',
attribute='exporters', full=True, null=True)
class EmbeddedExporterListResource(resources.MongoEngineResource):
exporter = ReferenceField(to='api.resources.ExporterResource',
attribute='exporter', full=True)
And when trying to update a PipeResource, I've got this error :
File "/lib/python2.7/site-packages/mongoengine/queryset.py", line 639, in _lookup_field % field_name)
InvalidQueryError: Cannot resolve field "resource_uri"
So am I doing things right or do I miss something ? Because it seems that Tastypie hands the resource_uri field to MongoEngine, and it shouldn't...
I precise that the EmbeddedExporterListResource is not only a ReferenceField, but contains other fields
Thansks for your help, I post this on stackoverflow too : http://stackoverflow.com/questions/13287098
Let's say I have an article document with a list of references to image documents (which are dynamic).
class Image(DynamicDocument):
something = StringField(required=True)
class Article(Document):
images = ListField(ReferenceField(Image))
class ArticleMongoResource(MongoEngineResource):
images = fields.ReferencedListField(of='app.api.ImageResource',
attribute='images', full=True, null=True)
class ImageResource(MongoEngineResource):
... Now when I POST and add a number of arbitrary fields to images they don't seem to picked up, it seems to behave like a regular document (not dynamic), i.e.:
{ "images": [{"something": "abc", "dynamic": "def" }]
Here the "dynamic" field isn't picked up and saved, it is stripped somewhere.
Is there anything wrong with above code? What could be the case here?
Since this fix in MongoEngine (0.6.11+) tests fail with:
ValidationError(You can only reference documents once they have been saved to the database: ['person'])
at:
.../django-tastypie-mongoengine/tests/test_project/test_app/tests/test_basic.py", line 146, in test_basic
self.assertEqual(response.status_code, 201)
AssertionError: 400 != 201
Support for embedded list field subresources schema output.
Also support polymorphic embedded documents.
Currently django-tastypie-mongoengine depends on mongoengine>=0.8.1,<0.8.2, can you bump that to 0.8.4? It seems to be working just fine with it. Are there any know issues with 0.8.4?
Support for filtering on embedded list field subresources.
This is closely related to #57. Using the same documents and resources described in that ticket, POSTing a TopLevelResource or TopLevelListResource with nonempty lists of references to ReferredResources succeeds, but the references are not actually created -- embedded.refs ends up empty.
I haven't figured out a fix for this issue, but I have a rough idea of why it's happening. It comes down to how tastypie handles m2m resources. They are not hydrated during the full_hydrate() pass, but there is a separate call to hydrate_m2m() and save_m2m() in Resource.save(). ReferencedListFields are m2m, so they follow this pattern.
The problem comes when the ReferencedListField is a member of an embedded document, because there is no logic built into the save() method to save m2m fields on embedded documents. The closest analog that tastypie supports would be a ToOneField pointing to a resource with a ToManyField. This works in tastypie because Resource.save() calls Resource.save_related(), which calls save() on the related resource that the ToOneField points to, and save() in turn calls hydrate_m2m() and save_m2m(). However, this doesn't work in our case because embedded documents aren't their own resource -- we don't call save() on them, so there is no opportunity to call hydrate_m2m() and save_m2m().
That's the nub of the problem -- the embedded documents are kind of acting like related resources, but we don't call save on them, so we don't save their m2m fields. My best idea for a fix for this is to add an is_embedded attribute to EmbeddedDocumentField and EmbeddedListField (analogous to the is_m2m attribute). Then, in MongoEngineResource.save(), notice any is_embedded fields and call their hydrate_m2m() and save_m2m() methods. Except this won't exactly work, because I think hydrate_m2m and/or save_m2m have some code that assumes they are being called in the context of a top-level resource whose object has a functioning save() method and a pk and everything, which won't be the case here.
If you are inheriting from MongoEngine's QuerySetNoCache() instead of QuerySet() for a custom QuerySet, the you will get the following error:
File \"/usr/local/Cellar/python/2.7.5/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/tastypie/resources.py\", line 1930, in build_filters
query_terms = self._meta.queryset.query.query_terms
AttributeError: 'CustomQuerySet' object has no attribute 'query'
If you lift the code from lines 32-41 of resources.py and add it to your custom QuerySet class, things will work. Seems like that code is very specific to using the cached QuerySet and not supporting the non-cached version?
Currently it's not possible to filter by values stored in EmbeddedDocumentField.
When attempting to search by any of the embedded document fields - the error is thrown in "tastypie/resources.py", line 1584, in check_filtering function: raise InvalidFilterError("The '%s' field does not support relations." % field_name)
It is possible to force django-tastypie-mongoengine to allow search by that field (by wrapping the field resource in a class that overrides the is_related value), however it does mean breaking the create/edit actions via the API.
Support for sorting on embedded list field subresources.
How to use django-tastypie-mongoengine to upload file image via api?
I am trying to send date_time from jQuery post to our server we are using mongoDB as backend and using django_tastypie_mongoengine for posting so far i have tried putting date="2010-11-10T03:07:43" and also date="2013-05-21T02:17:55.544000" in my jQuery but it is failing everytime.
I want to know the exact syntax of sending date
Current implementation is really badly implemented as it is based on code which assumes transactions. For MongoEngine (and MongoDB) this is of course not true, so some improvements to operations should be done to implement them through atomic operations. And not through current fetch-update-save cycle.
Even worse is for subresources (lists), especially because we use indexes so things could move around and something would not be anymore on its place. You want to delete n-th element, but that element could be already something else at the time it is processed. Maybe we should introduce some dummy UUID/PKs to make sure we know what we are operating on. Operations on subresources should be really implemented through MongoEngine/MongoDB atomic operations on list and not changing list in the code.
Hi,
Since c9bedc3, Mongoengine's validate() method is called before returning the bundle.
I understand that is used to handle validation errors and to return the proper error message, but this awkward when doing auto-allocation on required fields in document's save() method for example.
Won't the validation reporting be in a better place in obj_create() and obj_update() methods ?
If you're agree, just say it and I'll make a pull request ;)
Add CONTRIBUTING file which seems GitHub displays to users when opening tickets.
Hello,
I would like to know if there's a way to know from meta what type of field is my primarykey ?
It will help to fix this issue : concentricsky/django-tastypie-swagger#66
@mitar have you an idea about this please ?
Thanks
