django rest framework, not serializable
I am new at using the django REST framework and I am having trouble to import a list of the members of a team my query is team_name_list = Project.objects.get(id=kwargs['pk1']).team_id.members.all() which give an output : <QuerySet [<MyUser: johndoe@gmail.com>, <MyUser: johndoe2@gmail.com>, <MyUser: johndoe3@gmail.com>, <MyUser: johndoe4@gmail.com>]> The thing is when I try to import it in my context I get an error Object of type 'MyUser' is not JSON serializable I guess because the output of my query should be something ["johndoe@gmail.com","johndoe2@gmail.com","johndoe3@gmail.com","johndoe4@gmail.com"] How can I make it work -

Django: string representation from choices list [duplicate]
This question already has an answer here: Django: Display Choice Value 3 answers Is there a way to use django's model choices to obtain a string representation? I am trying to avoid having to write a long series of if-thens or switch conditions. I have many lists of tuples for various choices in my models.py, like this: FOOD_CHOICES = ( ("1", "Pizza"), ("2", "Hamburger"), ("3", "Hoagie"), ) The point was to obtain a quick numeric representation of each choice, while allowing admins to see the actual choices on the admin page. But now I would also like to get "Pizza" instead of "1" when I pass a query to a web page. It seems like the only way to do this is to use a series of If-thens, and I would really like to avoid that because there are dozens of choices that are only going to increase as time goes on. -
Django Rest Framework API in AWS cant use user token
So i have created a database and API for user to use it to register, login, see current user profile and log out. This work perfectly locally so i uploaded it into AWS. The register and login works but when using the token from the login. the data i get is blank. Even using the token for logout also got error.

What's the rationale of using properties instead of fields within the File model of django-filer
I tried to do filtering for the extension field, which is actually not a field at all as the following example suggests. For the sake of this example, let's imagine we have a running Django with django-filer installed and some file already uploaded. >>> from filer.models import File >>> File.objects.all()[0].extension 'some_ext' # just as example But when trying to filter: >>> File.objects.filter(extension='pdf') django.core.exceptions.FieldError: Cannot resolve keyword 'extension' into field. Choices are: _file_size, clipboarditem, description, downloadfilemodel, file, filer_image_file, folder, folder_id, has_all_mandatory_data, id, in_clipboards, is_public, modified_at, name, news_attachment, original_filename, owner, owner_id, polymorphic_ctype, polymorphic_ctype_id, sha1, uploaded_at This is because extension are not stored with the model but in fact are computed properties. My question: What's the rationale of not storing this meta data in the File Model. -
Adding languages dynamically through Django Admin
If I have a project which is using english language and I have all the string fields with translator helpers like this: from django.utils.translation import ugettext as _ from django.http import HttpResponse def my_view(request): output = _("Welcome to my site.") return HttpResponse(output) But I have potential users from other languages (which I dont know which languages are yet). Is it possible to add a new language like french, russian, etc from django admin without modifying django settings and adding the language there? -

WSGIDaemonProcess, Etc. Causing Connection Timeout in Debian 9
I was previously running Debian 8 and hosting my Django app using the following setup: Django 1.11 mod-wsgi 4.5 apache 2.4 mysql Now that I have updated to Debian 9, and using mariaDB, I am having an issue using the following settings in my apache2.conf file: LoadModule wsgi_module "/root/.virtualenvs/user/local/lib/python2.7/site-packages/mod_wsgi/server/mod_wsgi-py27.so" WSGIScriptAlias / /home/user/web/user.com/project/project/wsgi.py WSGIDaemonProcess user.com socket-user=user group=user processes=2 threads=25 WSGIProcessGroup user.com WSGIPythonHome "/root/.virtualenvs/user" <-- outside of virtual host I took each line out to see which was causing the issue, with LoadModule wsgi_module "/root/.virtualenvs/user/local/lib/python2.7/site-packages/mod_wsgi/server/mod_wsgi-py27.so" being the only one that was allowed to be in there and not cause the site to hang. By taking out all of those lines, my site works (albeit, without static files) and is not running in Daemon mode...

NoReverseMatch error in rendering Django

Many-to-many relationship with 'through' model returning error on migration

Here is the Profile, followed by a Pair model: class Profile(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, null=True, blank=True) pair = models.ManyToManyField('self', through='Pair', symmetrical=False, related_name='pair_to+') class Pair(models.Model): requester = models.ForeignKey(Profile, related_name='pairing_requester') accepter = models.ForeignKey(Profile, related_name='pairing_accepter') requester_learns = models.CharField(max_length=60, null=True) requester_teaches = models.CharField(max_length=60, null=True) The relationship between profiles should be symmetrical, such that (profile1, profile2) are a unique object and I should not expect a (profile2, profile1) to be created.
