Why do I get "CommandError: App 'app_name' does not have migrations." when using Heroku?
So I have deployed my Django project to Heroku, and now trying to migrate the database. I have everything working fine in my local sever. Then I tried to run the commands in heroku, as below. heroku run python manage.py makemigrations app_name'. This worked fine. Migrations for 'app_name': contents\migrations\0001_initial.py - Create model Book - Create model Category - Create model Content Then of course, I tried : heroku run python manage.py migrate app_name. But then I got this error CommandError: App 'app_name' does not have migrations. I've done some research for possible issues, none of which were relevant to mine. For example I do have __init__.py in the migrations folder inside app_name directory. Also, I've tried heroku run python manage.py migrate as well as heroku run python manage.py migrate app_name. I'm very confused. What do you think is the problem? Thanks in advance. :) -

Django Restframework - Multiple models for SearchFilter
Using Django 3.2 with Restframework. Iam trying for search filter and create a API with restframework which would output the searched term with its whole object. I had a little success on that with official doc. But from that I can only search in a single Model and not as globally. Is there any existing document, blog on how to use multiple Models together?

How to retrieve session data before reset in password change view?
I have override Django PasswordChangeView using Ajax (JQuery Form pluggin) and it works except all session variables are reset. Reading Django documentation, I understand it is the "normal behavior" but I need to reinitialize some session data ; if not, it would have no real interest changing password using Ajax... At start, I thought that call update_session_auth_hash function was responsible for that behavior but it seems not to be true as in form_valid function, request.user is set but request.session data are reset, even before fom is saved... So my question is WHEN/WHERE I can retrieve session variable to be re-set when PasswordChangeView is called? class PasswordChangeView(auth_views.PasswordChangeView): def form_valid(self, form): print('request.user',self.request.user) # return connected user print('request.session.get("selected_database")',self.request.session.get("selected_database")) # return None self.object = form.save() update_session_auth_hash(self.request, self.object) # prevent user’s auth session to be invalidated and user have to log in again print('request.session.get("selected_database")',self.request.session.get("selected_database")) # return None return JsonResponse ({'data': form.is_valid()},status = 200) -

Django Login Message with LoginView
I am a bit confused on why my LoginView message is not pulling the users login name. I have tried a few different ways and it either will say 'Welcome Anonymous User' or 'Welcome' (not adding anything). I have tried a few different methods and the results are the same each way I try to solve it. My code is as follows: class MyLoginView(LoginView): template_name = 'registration/login.html' success_message = 'Welcome' def form_valid(self, form): """Add message here""" messages.add_message(self.request, messages.INFO, f"{self.success_message} {self.request.user}") return super().form_valid(form) This one will say 'Welcome AnonymousUser', if I change the code to {self.request.user.username} it just will say 'Welcome' also have tried class MyLoginView(LoginView): template_name = 'registration/login.html' def form_valid(self, form): messages.success(self.request, f'Welcome {self.request.user}') return super().form_valid(form) This one will flash the message of 'Welcome Anonymous User'. If I change the code to f'Welcome {self.request.user.username}' then the message displayed is just 'Welcome' I am not really sure why these aren't working so any help would be greatly appreciated
