I'm using jqueryui on my site. When i install Dajax, it works, but it broken all my jqueryui layout.

How can i make for this works ?

I didn't find any documentation about to use Dajax with JQuery.

Can you help me ?

Not sure if this is a dajax or JavaScript problem.

I am sending serialized form data data to my ajax function like this:

    form_data = $('#email-form').serialize(false);
    Dajaxice.escola.build_emails('Dajax.process',{'form_data':form_data});

and receiving the data like this:

def build_emails(request, form_data=None):
dajax = Dajax()

but in this case form_data is None and I get the following error:

ERROR:root:DAJAXICE argv exception Unterminated string starting at: line 1 column 13 (char 13)

the correct value of form_data should be something like "to_func=on&additional=&subject=&message=" I found that adding this line to my JavaScript fixed the problem:

    form_data = encodeURIComponent(form_data);

Interestingly, I didn't have to add a corresponding urldecode function to my ajax function as the passed form_data is already decoded automatically somehow

I have set @csrf_exempt on my view and I am still getting a csrf error when POSTing to it.

code:

@csrf_exempt
@require_person_viewed_is_verified
@dajaxice_register
def profile(request, id):
profile = Profile.objects.select_subclasses().get(id = id)
return model_to_dajax(profile, False, 'profile', 'feeds/single_proper.html').json()

Just a quick bug report: Chromium was interpeting these lines from
jquery.dajax.core.js incorrectly:

$(elem.id).addClass(this);
$(elem.id).removeClass(this);

It was not resolving "this" as a string, and instead passed "this"
into the function as a reference. I added a manual ".toString()" that
resolved the problem:

$(elem.id).addClass(this.toString());
$(elem.id).removeClass(this.toString());

Hi. I am new to django and very new to dajax, I want to ask you for some help.

I installed to run the examples of django-dajax (download the archive dajax-examples.tar.gz), and tried to run it using command python manager.py runserver

In every example I get the same error:

Caught an exception while rendering: 'module' object has no attribute 'get_media_prefix'

Can anybody help me?
I think I've installed something wrongly or something is missing.
Thank you very much

When i use localized data in my forms with Dajax i get error:

  UnicodeEncodeError: 'ascii' codec can't encode characters 

in dajax/core/Dajax.py on _clean(self, data):

   return str(data).replace('\n','').replace('\r','')

Maybe it should use 'unicode()' instead of 'str()' ?

In the section where is an example of Append, the example uses Assign.
http://django-dajax.readthedocs.org/en/latest/api.html#append-selector-attribute-value

https://github.com/jorgebastida/django-dajax/wiki

Hi,

When i was testing your project, i see a problem on this page http://www.dajaxproject.com/forms/

IE is strict : It can't modify the innerHtml of select and other element such as tr, td etc...

Thx

Those examples in your demo are broken.

None of the online examples at djangoproject.com works at the moment:

Uncaught TypeError: Object 
...
<div id="summary">
  <h1>Forbidden <span>(403)</span></h1>
  <p>CSRF verification failed. Request aborted.</p>
...

The reason is a backwards incompatible change in Django 1.2.5 that requires AJAX requests to be CSRF protected too.

See here: http://docs.djangoproject.com/en/1.2/releases/1.2.5/#csrf-exception-for-ajax-requests

in the full form example :

https://github.com/cowboy/jquery-misc/blob/master/jquery.ba-serializeobject
should be

https://github.com/cowboy/jquery-misc/blob/master/jquery.ba-serializeobject.js

I wanted to put a loading.gif while the ajax with Jquery is being processed, but he does not call the events of jquery. I as follows:

$("select#id_estado.select_black_style").change(function() {
$(document).ajaxStart(function(){
$("#teste").show();
});
$(document).ajaxStop(function(){
$("#teste").hide();
});
Dajaxice.apps.localizacao.updatecombo_estadocidade(Dajax.process,{"option":this.value});
return false;
});

This does not work.

Django-pipeline (which is a css/js compressor) collects together all js files into a single js file, and then wraps it into an anonymous function like this:

(function(){ ... })();

This results in onclick scripts on all pages breaking because they cannot find Dajax. (Dajax is currently defined in jquery.dajax.core.js as a "var Dajax", so obviously it is not visible outside the anonymous function. Link.

Suggested fix: At the end of the file, expose the Dajax variable:

window.Dajax = Dajax

(as is done by jQuery).

Temporary workaround for others facing the same problem:

Set PIPELINE_DISABLE_WRAPPER = True

to disable wrapping all the code in an anonymous function. This works but is not an ideal solution.

HELLO,

I met following issue when i try to use dajax:

Traceback (most recent call last):

File ... in process
response = '%s(%s)' % ( callback, thefunction(self.request, **argv) )

File ,,, line 37, in join
return dajax.json()

AttributeError: 'Dajax' object has no attribute 'json'

Coud you give me any hint on it?

Thanks

Hi all,
would it make sense, is it possible to add a html() like function.
This would enable us to replace/add certain parts of the documents out of Django Templates.
Thanks
Juergen

1. The example here http://dajaxproject.com/fullform/ doesn't show the definition of send_form() I had to look at the page source to see the Dajaxice.examples.send_form() command
2. The example here http://dajaxproject.com/forms/ doesn't work in Internet Explorer. Not really a dajax bug, but still confusing. Here's a discussion of the issue: http://stackoverflow.com/questions/1293427/innerhtml-replace-does-not-reflect

ImproperlyConfigured at /maps/
Error importing template source loader django.template.loaders.filesystem.load_template_source: "'module' object has no attribute 'load_template_source'

I guess this has something to do with the following...

Function-based template loaders
Django 1.2 changes the template loading mechanism to use a class-based approach. Old style function-based template loaders will still work, but should be updated to use the new class-based template loaders.

Is this something that can easily be updated ?

Where: /dajax/core/dajax.py line 85
What: This should be changed to unicode(data, 'utf8')
Why: Causes encoding problems (UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position _: ordinal not in range(128) ) when given certain characters. The function is trying to decode to ascii before encoding to unicode, because that is the default. Thus, my change would have it use utf8 instead of ascii as the decoder before the unicode encodes.

:D

Hi,
I have a little Wiki running on Django 1.3.1 with Dajaxice 0.2 and Dajax 0.8.4.
Everything is running fine on Firefox, Chrome and Opera. By accident I discovered this little problem with IE8:

I have implemented the Pagination example from http://dajaxproject.com/pagination/. In order to avoid CSRF token issues I got rid of the tokens in views that have Paginations.

IE8 gives the following error message:
Unbekannter Laufzeitfehler (approx. "Unknown runtime error")
prototype.dajax.core.js
line: 23
code: 0
char: 50
URI: http://www-elektronenmikroskopie.uni-regensburg.de/media/js/dajax/prototype.dajax.core.js

I'm not sure whether this is an issue solely caused by Dajax because the Pagination example on http://dajaxproject.com/pagination/ is working fine.

I would appreciate any ideas...

Two issues:

1. When an error occurs in an ajax function, only the Exception is printed and there is no stack trace or line number. This makes it very difficult to figure out where the error occurred.
2. The error message is outputted to sys.stdout which is not allowed when running in mod_wsgi and generates the error below. Error messages should be printed to sys.stderr to appear in the server error log.

Finally, instead of logging errors in the server log by printing to sys.stderr is there anyway to log errors with the normal Django error handler that generates an email? The default Django error emails contain lots of useful information and we are notified immediately by email instead of having to search through a server log.

File "/home/escolaterrafirme/apps_wsgi/django/core/handlers/base.py", line 86, in get_response

hello
is it possible to call the function like this into the future version ?

Dajaxice{
application: $(this).attr('data-application'),
view : $(this).attr('data-view'),
('Dajax.process', {...})
}

Thanks!

Would be good to have PEP8 [1] compliance regarding naming style.

Code like:
dajax.removeCSSClass(...)

Breaks the common naming style of both Python [1] and Django [2]. According to PEP8, the recommendation would be:

dajax.remove_css_class(...)

I know it's down to personal preference, but surely makes Dajax alien in the middle of a PEP8 compliant, Django project. If it ever made into Django contrib, this would have to be fixed too, so I think it's a great idea to get this right from the beginning.

[1] http://www.python.org/dev/peps/pep-0008/

[2] http://docs.djangoproject.com/en/dev/internals/contributing/#coding-style

Setup:

• Django 1.4.1
• PostgreSQL with UTF-8

When querying a table with all countries for selection this error is thrown:

return unicode(data).replace('\n','').replace('\r','')
UnicodeDecodeError: 'ascii' codec can't decode byte 0xc3 in position 2115: ordinal not in range(128)
response: DAJAXICE_EXCEPTION

The problem is the unicode command in django.py (http://docs.python.org/howto/unicode.html)

def _clean(self, data):
    if hasattr(data,'__iter__'):
        return map(self._clean,data)
    else:
        try:
            return unicode(data).replace('\n','').replace('\r','')
        except Exception: # Used to avoid the exception 
            return data; # Used to avoid the exception 

This is a quick and dirty fix, I have no idea if it is a good idea to do this.

Not sure if something changed a newer version of Django, but this code doesn't work for me in Django 1.0.1:

http://dajaxproject.com/fullform/

form = ExampleForm(form)

I had to decode the URI string into a dictionary first like this:

qd = QueryDict(form)
form = EmailForm(qd)

Hey,

So when I use mootools, dojo or prototype I get no errors while using dajax( I currently use 0.5.2v dajaxice,0.9.2v dajax, 1.4.1 django ).
I have followed the documentation for Dajaxice and Dajax to set the project. And like I mentioned before it works with the other JS frameworks just not jquery. I have also tested it with different versions of jquery and I get the same error.
I get the following error:

ERROR:django.request:Internal Server Error: /dajaxice/projects.employeeSearch/
Traceback (most recent call last):

This is what I am doing in my template:

        function my_callback(data){
              alert(data+' received from server');
        }    
        </script>

             .
             .
         </script>

         {% block content  %}
          <form id="target" action="/resultsLC/" method="get">

         <input type="text" name="employeeid" id="employeeid" value="" placeholder=Employee   
     required onblur="Dajaxice.projects.employeeSearch(Dajax.process,{'employeeid':$('employeeid').value});">
        .
            .

ajax.py

from dajax.core import Dajax
from dajaxice.decorators import dajaxice_register
from projects import SearchForm
@dajaxice_register
def employeeSearch (request, employeeid):
dajax = Dajax()
result = SearchForm.search(emp)
dajax.assign('#employeeid', 'value', str(result))
return dajax.json()

In my chrome browser console this is the error message I get.
Dajaxice: Something went wrong. dajaxice.core.js:114

EXCEPTION: 'DAJAXICE_EXCEPTION',
default_settings: {'default_exception_callback': function(){ console.log('Dajaxice: Something went wrong.')}}

If you could illuminate what I am doing wrong I would really appreciate it.

Thanks

The "simple form example" in the online documentation should be updated to reflect changes in the example code, not only because of the code style, but also because the += in the loop creates a bug in the HTML generation.

In my setup, I found that if django_dajax was installed as a zipped egg (e.g. easy_install -z django_dajax), then collectstatic failed to find dajax/jquery.dajax.core.js and other dajax static files. The problem went away when I forced easy_install to do an unzipped install (easy_install -Z django_dajax).

I have not really determined whether this is a problem with DajaxiceFinder, or Django staticfiles in general, or whether it was with django-pipeline (which I am also using) - so I cannot give a suggested fix for sure.

However, putting up the issue here, along with the suggested workaround (easy_install -Z) for the benefit of anyone else who runs into this problem.

dajax.assign("#myID", 'onchange', "myJSFunction();") is not working right now because onchange is not an attribute.
It should be useful either to add a new function to handle events or to change the actual "as" command to handle events correctly.

Thank you.

Today I tried dajax and found it very usefull. I use jquery 1.4 and therefore jquery.dajax.core.js. The add_css_class and remove_css_class function did not work, all other functions did work.
After a bit of testing I found that changing the function from:
jQuery.each(elem.val,function(){
$(elem.id).addClass(this);
});
to:
jQuery.each(elem.val,function(){
$(elem.id).addClass(""+this+"");
});
did solve the problem. The same change did work for the remove_css_class function.

Hello

We load a form with a ajax post command. When the form is loaded and the page is reloaded with f5 the ajax.py methods are registred twice in the generic java script:

var Dajaxice = {
portal: {
ajax_load_home: function(callback_function, argv, custom_settings){
Dajaxice.call('portal.ajax_load_home', callback_function, argv, custom_settings);
}
contact: {
Uncaught SyntaxError: Unexpected identifier // Added by google chrome dev view
ajax_load_contact_form: function(callback_function, argv, custom_settings){
Dajaxice.call('portal.contact.ajax_load_contact_form', callback_function, argv, custom_settings);
},
ajax_save_contact_form: function(callback_function, argv, custom_settings){
Dajaxice.call('portal.contact.ajax_save_contact_form', callback_function, argv, custom_settings);
},
send_form: function(callback_function, argv, custom_settings){
Dajaxice.call('portal.contact.send_form', callback_function, argv, custom_settings);
}
}
},
contact: {
ajax_load_contact_form: function(callback_function, argv, custom_settings){
Dajaxice.call('contact.ajax_load_contact_form', callback_function, argv, custom_settings);
},
ajax_save_contact_form: function(callback_function, argv, custom_settings){
Dajaxice.call('contact.ajax_save_contact_form', callback_function, argv, custom_settings);
},
send_form: function(callback_function, argv, custom_settings){
Dajaxice.call('contact.send_form', callback_function, argv, custom_settings);
}

}

ajax.py of the form:

from dajax.core import Dajax
from dajaxice.core import dajaxice_functions
from portal.contact import views
from django.views.decorators.csrf import csrf_exempt
from forms import ContactForm
from django.middleware.csrf import get_token

def ajax_load_contact_form(request):
get_token(request)
dajax = Dajax()
dajax.assign('#contentText','innerHTML',views.post_contact(request))
return dajax.json()

def ajax_save_contact_form(request):
get_token(request)
dajax = Dajax()
dajax.assign('#contentText','innerHTML',views.save_contact(request))
return dajax.json()

@csrf_exempt
def send_form(request, form):
dajax = Dajax()
form = ContactForm(form)
dajax.assign('#contentText','innerHTML',views.save_contact(form))
return dajax.json()

dajaxice_functions.register(ajax_load_contact_form)
dajaxice_functions.register(ajax_save_contact_form)
dajaxice_functions.register(send_form)

Is there something wrong in the code or a bug? I can't see it.

Thanks

How to reproduce :
1/ Open with ie8 http://www.dajaxproject.com/forms/
2/ Select a country
3/ City do not appears.

I did code another example. Same result.

Any info is welcome.

I have problems with the sentence Dajax.process, does not work... It does nothing. The examples of dajaxice don´t have any problem...

Hi,

I have an error assigning a value using dajax with jquery:

example command:
dajax = Dajax()
dajax.assign('#example','value', random.randint(1, 10))
return dajax.json()

I traced it down to jquery.dajax.core.js. The clear_quotes funtion doesn't exist:

            case 'as':
                elem.val = clear_quotes(elem.val);
                jQuery.each($(elem.id),function(){ this[elem.prop] = elem.val; });

Hello, and thanks for your hard work on these libraries

Not a core issue, but in the full forms example at http://www.dajaxproject.com/fullform/
I believe there's an error in the send_form() function provided:

function send_form(){
      data = $('my_form').serialize(true);
      Dajaxice.examples.send_form(Dajax.process,{'form':data});
}

• 'my_form' should be '#my_form' ? Working through the example was less than fruitfull till I added the #.

Cheers

When an error occurs it is generally unrecoverable, however an error message is repeated over and over on the client. I sugest adding the return statement below:

            default:
                alert('Unknown action!');
                return false; // error reported, exit each loop

Submitted this in error to the dajaxice repo several months ago-- I'm not sure if it has been fixed since then.

I have a non-blank SERVER_ROOT_URL for a particular project, which means URLs for all the views in my project are of the form:
www.mysite.com/project_name/some_view

Instead of:
www.mysite.com/some_view

My configuration is only this way in the production server, not the dev server. Consequently, dajax works great on my dev server but not the production server. It seems the reason for this is because dajaxice uses only DAJAX_MEDIA_PREFIX to generate the paths to the ajax views and doesn't take SERVER_ROOT_URL into account. The result on my production server is that the ajax view urls look like this:
www.mysite.com/dajaxice/myapp.some_view

When they should really look like this:
www.mysite.com/project_name/dajaxice/myapp.some_view

Can you offer some insight here? I've spent hours trying to figure out if I just had it configured incorrectly... I tried changing the DAJAX_MEDIA_PREFIX to something else but it didn't seem to fix the problem since you have multiple dependencies on that prefix in your code...

The example on http://dajaxproject.com/fullform/ is broken.

One problem is that the example code that's displayed under "html" doesn't include the <script> needed to serialize the form data and ship it off to the server.

Another is that Dajax/Dajaxice isn't working for me, for jQuery 1.4.2. I get a "process_form() takes exactly 2 arguments (1 given)" traceback on the server. The call I'm using is

Can you give me a hint as to where I should look to find the problem? Or is the problem that jQuery 1.4.2 isn't supported by Dajax?

Thanks!

Just a newbie for dajax, it seems Jquery 1.5.1 not support well

Could not be used with Spanish or other language with accents.

I am having an issue where when I try to validate a form from a model with a Many-to-Many field. The Form will not validate unless I select more than one item from the select-box.

Model validates fine when submitting form with standard POST method

Using jQuery serializeObject script as suggested in the tutorial

The firebug is pointing in the following javascript errors:
jquery.dajax.core.js - $ is undefined $.each(data, function(i,elem){
prototype.dajax.core.js - Class is not defined var Dajax = Class.create();
mootools.dajax.core.js - data.each is not a function data.each(function(elem){
dojo.dajax.core.js - dojo is not defined dojo.forEach(data, function(elem,i){

Hi all. I have the message "'dajax_templatetags' is not a valid tag library" executing the dajax-examples refering to the first line in the template. I installed dajax and dajaxice following instructions. I would grateful for any tip.

Hi there.

When I request a form via django-dajax I get

warnings.warn("A {% csrf_token %} was used in a template, but the context did not provide the value. This is usually caused by not using RequestContext.")

I there a way to set the csrf token in django-dajax using the request header (see https://docs.djangoproject.com/en/1.2/ref/contrib/csrf/#csrf-ajax).

What would be the best way to deal with this issue?

Thanks + great work!

Mischa

The example in the documentation has code() instead of script():

def code_example(request):
    dajax = Dajax()
    dajax.code('my_function();')
    return dajax.json()

line 85 of Dajax.py is the problem:

return unicode(data).replace('\n','').replace('\r','')

example ajax.py:

def edit_contact(request, object):
    dajax = Dajax()
    …
    html = render_to_string('contact_form.html', {'formset': formset})
    dajax.assign('#contactform', 'innerHTML', html)
    return dajax.json()

a textarea from the string html looks like:

<textarea id='street_address'>
    line1\nline2\nline3
</textarea>

but dajax returns this textarea:

<textarea id='street_address'>
    line1line2line3
</textarea>

On this page : http://wiki.github.com/jorgebastida/django-dajaxice/installation

The link to the example project is broken.

Thanks,

Running Internet Explorer 7 on WinXP. Most of my client base will be running this version and upgrading is not possible. The form at http://dajaxproject.com/forms/ allows the user to select a country but the second dropdown showing cities does not update. Form does work with other browsers.

I m running your examples on my local machine and receive the pop up error. when I select some country in Ajax Form Machine!
The error is

dajaxice_callback should be a function since dajaxice 0.2

I installed django-dajax and django-dajaxice using pip.
The only thing I changed in the examples code is in settings.py, where I added 'dajax' to INSTALLED_APPS
Please help.
