Pass parameters in URL to Django Admin add_view
I need to pass a parameter in the URL to the Django Admin add view, so that when I type the URL: http://localhost:8000/admin/myapp/car/add?brand_id=1, the add_view reads the brand_id parameter. I want to use this so that I can set a default value for the brand attribute of Car. def get_form(self, request, obj=None, **kwargs): form = super(CarAdmin, self).get_form(request, obj, **kwargs) form.base_fields['brand'].initial = <<GET['brand_id']>> return form Use case: I want this because in my BrandsAdmin, I have added a "+" button for each brand, that should add a Car with that Brand as FK. I've tried getting it from request in get_form, but when that code is executed, Django has already changed my URL as I guess it doesn't understand it as a "legal" parameter. Thanks a lot! -

Build MultipleChoiceField form based on view request with Django
I have a table named Appointment with : timeslot id ; student id; teacher id ; date ; timeslot (integer) ; I would like to create multiple rows in the table TimeSlot based on MultipleChoiceField form.

Something like where I can choose the timeslots. Then the selected timeslots are stored in the Appointment … -

How to fix heroku app deployment? App runs locally but not online

Is there a workaround for Django's `ModelDoesNotExist` error in a situation like this?
So I get a ModelDoesNotExist error when I run manage.py runserver because in a file in my directory, I make a query to a table which has not been populated yet. def __init__(self): self.spotify_object = SocialToken.objects.get(account__provider="spotify") The above is a class instantiated to perform some sort of authentication and the SocialToken table gets populated only after I login. Now, I was wondering if there was a way to escape the error by triggering this part of the code only after I login? I only use the class in an endpoint, and during that period, the table would have been populated but the fact that it is not populated before running the server is causing a DoesNotExist error.
