Re: I am not able to pass a variable to a widget with its "mark_safe" attribute intact.

[Dennis Marwood]

I found that the "correct" way to address this issue is to use 
raw_id_fields.

Re: Errors with django-rest-auth and django-allauth

[Luis Zárate]

As say Stephen Butler you need to install django.contrib.sites (it not
enable by default) and set

SITE_ID = 1 in your settings.

Here is the reference:

Custom UserChangeForm shows one list correctly and the other doesn't show values

[Néstor Boscán]

Hi

I've created a custom UserChangeForm in DJango 1.7.8 where I have 2 custom
ComboBox associated with a Model. Both are defined exactly the same. One
shows the values and the + button to add a new entity. The second only
shows an empty list.

Any ideas?

Regards,

Néstor

Re: comment and uncomments in django html template

That is totally false. Anything within a Django comment tag will not be 
rendered in the output, whether it's HTML or JS.

But if you need comments inside JS scripts, why don't you use JS comment 
syntax?

Re: Errors with django-rest-auth and django-allauth

[Stephen J. Butler]

One of your other apps needs django.contrib.sites, so you need to put it in
your INSTALLED_APPS. That's what this means here:

Model class django.contrib.sites.models.Site doesn't declare an explicit
app_label and either *isn't in an application in INSTALLED_APPS* or else
was imported before its application was loaded.

And here:

Field defines a relation with model 'Site', which is either *not installed*,
or is abstract

Errors with django-rest-auth and django-allauth

[Daniel Grace]

I have installed Django (1.8), django-allauth (0.20.0) django-rest-auth 
(0.4.0).

I added to INSTALLED_APPS in settings.py:
'rest_framework',
'rest_framework.authtoken',
'rest_auth'
'allauth',
'allauth.account',
'rest_auth.registration',
'allauth.socialaccount',
'allauth.socialaccount.providers.facebook',

And I added to TEMPLATES - OPTIONS - context_processors in settings.py:
'django.core.context_processors.request',
'allauth.account.context_processors.account',
'allauth.socialaccount.context_processors.socialaccount',

When I run the server (python manage.py runserver) I get several errors:
