ValueError at /akolaprofile/ The view akola.views.akolaprofile didn't return an HttpResponse object. It returned None instead
I am trying to modify a user's username in his profile. I'm not using Django's User model and had created a custom user model (MyRegistration) by inheriting AbstractBaseUser. I have also assigned my custom user model to AUTH_USER_MODEL in the settings.py. But when I try to modify the user's profile details, it throws a ValueError stating that The view akola.views.akolaprofile didn't return an HttpResponse object. It returned None instead. What could possibly be wrong? Also, I want to understand why is_valid() function has been ditching me every time ever since I created my own user model. It just doesn't work in any form. Below are my codes: models.py: from django.db import models from django.contrib.auth.models import AbstractBaseUser, PermissionsMixin from django.utils import timezone from .manager import FirstManager #Making custom User model class MyRegistration(AbstractBaseUser, PermissionsMixin): location_list=[ ('Solapur', 'Solapur'), ('Latur', 'Latur'), ('Dhule', 'Dhule'), ('Akola', 'Akola'), ('Nashik', 'Nashik') ] username=models.CharField(max_length=10, unique=True) email=models.EmailField(unique=True) first_name=models.CharField(max_length=150) last_name=models.CharField(max_length=150) location=models.CharField(max_length=10, choices=location_list, default='Latur') designation=models.CharField(max_length=70) is_active=models.BooleanField(default=False) is_staff=models.BooleanField(default=False) start_date=models.DateTimeField(default=timezone.now) last_login=models.DateTimeField(null=True) USERNAME_FIELD='username' REQUIRED_FIELDS=['email', 'first_name', 'last_name', 'location', 'designation'] objects=FirstManager() def __str__(self): return self.username views.py: Line no. 7 here, print(fm.is_valid()) returns True in the terminal, still the code returns None. def akolaprofile(request): if request.user.is_authenticated: if request.method=='POST': print(request.POST) fm=ProfileForm(request.POST, instance=request.user) if fm.is_valid(): print(fm.is_valid()) fm.save() else: return HttpResponse('Not … -

why my remote server not able to connect to postgres instance on another Django server?
I have two Ubuntu server A and B. Initially I had Django, postgres, celery on single server A. Everything was working fine. Now A has Django, postgres, and B has celery and Django project installed. DB migrations are done on A, and database connectivity is proper on A. This I can say that because when I am trying to start the celery server on server A, I am able to successfully launch the celery through the command prompt. No problem. As per the requirements, I have to only run Django and postgres on server A, and Celery on server B. Since I am using the same Django server settings on server B that I have in A, so the Django settings.py has the same DB connectivity settings as shown below. i.e. the DB settings are same on A and B DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': 'xyz', 'USER': 'smthing', 'PASSWORD': 'smthing', 'HOST': 'some_IP', 'PORT': '5432', } } To see if the postgres is running or not on server A.

should django modal have a separate view?
I am working on an application that has a page with a table that is a list of users. Each user has a button which pops up a modal that does something. I am trying to create the modal that will get the user information when the button in clicked, additionally, I need in that modal some logic based on the user information and some more data. I am thinking that it makes sense to create a separate view for it but since each view must be on a different url, the concept of the modal does not makes sense (for me), because I want it to be on the same url. Is it possible to have a modal with a different view that will have a separate logic? Since the modal is included in the template and it is basically just one template, then, can one template have 2 views? What is the best way to implement the modal using django? And how to pass data to it, I need the data from the row that was selected + some more data from db. I have the data from the context but manipulating that using JQuery for me is … -

Django Moving Models
I have a django application I'm trying to refactor. There's a million and five ways it seems to migrate models from an existing django app to a new one however I wanted to run by what seems like the easiest solution. Let's say my current application is called 'main-app' in said application i have a model 'user'. This would create a table called 'main-app_user' or something similar. Let's say I want to move the user model to a new app 'core', some tutorials state this is as easy as pointing the new model to the old table like so class User(models.Model): ... class Meta: db_table = 'main-app_user' I was curious if there was any catch to this I suppose? Many tutorial make this way more complicated so I'm curious why this isn't just the de-facto solution or if there are any drawbacks to this vs others. Thank you in advance! -
