I'm thinking about this for a while now,
I'm creating a chat application, in chat.models a class Room is specified, however, a Room can be related to anything in my project, since it uses a generic relation in it's foreign key.
Is there a way to know which model that Room is related knowing only the models name?
ctype = 'user' related_to_user = Room.objects.filter(content_type=ctype)
The problem I'm having is, the code below is in a view:
doc = get_object_or_404(Document, id=id) # get *or create* a chat room attached to this document room = Room.objects.get_or_create(doc)
If I don't want to use Document model, if I want a model associated to a string, a string that can be anything, without having to write tons of if's to get a specific Model for the specific string. Is there a way to find a model just by it's 'name'?
user_type = ContentType.objects.get(app_label="auth", model="user") user_type = ContentType.objects.get(model="user") # but this can throw an error if you have 2 models with the same name.
Very similar to django's
from django.db.models import get_model user_model = get_model('auth', 'user')
To use your example exactly:
ctype = ContentType.objects.get(model='user') related_to_user = Room.objects.filter(content_type=ctype)
