django: TestCase shows error only in script
I am checking whether my code runs correctly or not, using testcases If I run in the command line it works correctly >>> from django.test.utils import setup_test_environment >>> setup_test_environment() >>> from django.test import Client >>> client = Client() >>> from django.urls import reverse >>> response = client.get(reverse('polls:detail',args=(1,))) >>> response.context [{'True': True, 'False': False, 'None': None}, {'messages': <django.contrib.messages.storage.fallback.FallbackStorage object at 0xb74425ec>, 'perms': <django.contrib.auth.context_processors.PermWrapper object at 0xb69feecc>, 'user': <SimpleLazyObject: <function AuthenticationMiddleware.process_request.<locals>.<lambda> at 0xb7440bfc>>, 'csrf_token': <SimpleLazyObject: 'FrAJ52rWG57SSbSE9y4V2tammjvQqjBUyl2tK6aEzj8ZfENSyFl7Fy05bnQh3XyQ'>, 'request': <WSGIRequest: GET '/polls/1/'>, 'DEFAULT_MESSAGE_LEVELS': {'DEBUG': 10, 'INFO': 20, 'SUCCESS': 25, 'WARNING': 30, 'ERROR': 40}}, {}, {'object': <Question: What's Up?>, 'question': <Question: What's Up?>, 'view': <polls.views.DetailView object at 0xb6a2fd4c>}] >>> response.context['question'] <Question: What's Up?> But if test in the script it throws a key error: from django.test import TestCase from django.utils import timezone import datetime from polls.models import Question from django.urls import reverse def create_question(question_text,days): time = timezone.now() + datetime.timedelta(days=days) return Question.objects.create(question_text=question_text,pub_date=time) class QuestionDetailViewTests(TestCase): def test_past_question(self): past_question = create_question(question_text='past question',days=30) response = self.client.get(reverse('polls:detail',args=(past_question.id,))) self.assertQuerysetEqual(response.context['question'],['<Question: past question>']) It throws the following error: (mysite) sugumar@sugushivaatgmaildotcom:~/python/django/mysite$ python manage.py test polls Creating test database for alias 'default'...

How to apply variable taxes in a Strategy in django oscar?
I am working on an oscar project for India and now I want to apply taxes on products. I have followed the docs for applying taxes over prices and availability , forked the partner app. When I specified rate=('0.20'), it applied a tax of 20 % on all products, now I want to make it dynamic. So I went through the code for strategy.FixedRateTax,and I tried implementing the code for get_rate(), since it gets called for all the products. How I want to make it dynamic is, based on the product category I want to apply the tax on the product which is in get_rate(). So I created a model in core/models.py class CategoryTax(models.Model): category = models.OneToOneField(Category, on_delete=models.CASCADE, unique=True) gst_tax = models.DecimalField(max_digits=11, decimal_places=4, null=True, default=0) def __str__(self): return "%s" % self.category Here importing of the category model is working fine,but when I go to the strategy.py and import models from core, and the other apps, django gives an exception. My forked_apps/partner/strategy.py is: from decimal import Decimal as D from oscar.apps.partner import strategy, prices from django.conf import settings from oscar.core.loading import get_model from core.models import CategoryTax Partner = get_model('partner', 'Partner') Category = get_model('catalogue', 'Category') Product = get_model('catalogue', 'Product') ProductCategory = get_model('catalogue', … -
How to create a custom default text in choicefield
In my web application, i have a drop-down list created using ModelForm which is rendering well, however, i can't set default text like "Choose One Option", rather its showing the default "----" which I would love to override I have tried using forms.ChoiceField in my widgets but its still not making any difference from django import forms from . import models from .models import FacultyData class DepartmentCreationForm(forms.ModelForm): class Meta: model = models.DepartmentData fields = ['fid', 'dept_name'] data = [] #data.append((None, 'select one')) data.append(('20', "---Choose One---")) CHOICES = FacultyData.objects.all() for v in CHOICES: # fname = "%s -- $%d each" % (v.faculty_name, v.created_on) data.append((v.id, v.faculty_name)) widgets = { 'fid': forms.Select(attrs={'class': 'form-control'}), 'dept_name': forms.TextInput(attrs={'class': 'form-control', 'placeholder': 'Enter Department Name'}) } I expect the default output to be "Select One" but the actual output is "-----" -
Google Sign-in in Android with django-rest-auth
I've been trying to add Google Sign-In in Android but have a couple of doubts. From the Android documentation Integrate google sign in android In the server side authentication part Client Id is required which is OAuth 2.0 web application client ID for your backend server. From android's documentation: Get your backend server's OAuth 2.0 client ID If your app authenticates with a backend server or accesses Google APIs from your backend server, you must get the OAuth 2.0 client ID that was created for your server. To find the OAuth 2.0 client ID From my understanding the flow would be: Android app will get the auth code from google which will be passed to the backend. The backend will get the access token with the auth code from the android app and the client secret. With the acess token we get the user's information and the access token is saved in the database. My doubts are: I read somewhere on StackOverflow that we need to create two OAuth client one for Android and one for Web Application. Is this True? Django Rest Auth Login View need to have one redirect_url defined but I don't understand what would be the … -
django PDF FileResponse "Failed to load PDF document."
I am trying to generate and output PDF from a django view. I followed the example in django documentation using ReportLab but the downloaded PDF is not opening in any PDF readers.

Django & beforeunload event
I wanted to use the following code to fade the page out when the beforeunload event is fired. window.addEventListener("beforeunload", function (event) { $(document.body).fadeOut(600); }); I noticed that the page fades as expected when leaving and going to a different site, but the page does not fade when going from one app in my Django-powered site to another.

Some changes in docker container not being reflected in local code
Inside the docker container, I can make changes to /app directory and the changes will be reflected in my local code. Similarly, I can make changes in my local code and these changes will be reflected in the docker container. Inside the /app folder I have got /static directory. I can make changes inside /static and I can run the updated application, however these changes are not reflected in my local code. So basically changes to anything in static folder is not being reflected in local code. I thought it could be a permissions problem, ls -l showed that every folder in the /app directory was owned by user 'm' and group 'm', except the static directory which was owned by the user 'm' but belonged to the group 'root', but changing the group using chgrp didnt fix the issue.

Django Authentication credentials separate from user data
I am building a system where many accounts will not have login credentials (e.g companies) unless specifically provided. In order to achieve this, I have the following account model (not implemented yet, currently designing on a piece of paper): Table: Account Fields: ID, fname, lname, type, created_at, activated_at Table: AccountCredentials Fields: Account ID, email, password Relations: Account <- 1-to-1 -> AccountCredentials All permissions, operations etc will be performed over the Account model; so, the Account model will be the django auth user model. I have used custom User models and managers before; however, this is something I am not sure how to implement. How should I tell the AbstractBaseUser model to authenticate using credentials.email and credentials.password (credentials being the relation name between Account and AccountCredentials)? From checking AbstractBaseUser source code and checking some files, it seems like I can override get_username method; so that, the username field is being read from credentials. However, I am not sure how to do the same for password as it is hard coded in model. -

django-admin dbshell raises django.core.exceptions.ImproperlyConfigured
I know this question has been asked before, but none of them worked for me so far, so I'm going to give it a chance here. I'm trying to use MySQL as my database in django, but when I modify the settings.py and run the command: django-admin dbshell I get the following error: django.core.exceptions.ImproperlyConfigured: Requested setting DATABASES, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings. What I did: - I'm running windows 10. using pipenv, I create fresh virtual environment. install django. start new project. edit the settings.py in the settings.py I change the DATABASES to the following: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'test_db', 'USER': 'root', 'PASSWORD': '****', 'HOST': '127.0.0.1', 'PORT': '3306', } } also pip installed mysqlclient Weird thing is that when I make migrations, new tables are created, which means that DB works. why doesn't the command django-admin dbshell work? -
Django, How to enforce model Foreinkeys to have same value

What is the right way to handle views for multiple layers of user privileges?
Imagine this scenario: I want to set up a simple blog with three layers of privileges: author, moderator and admin. I am wondering what the best way to manage templates would be. Depending on the user type, all pages of the app should look in a different way. For example, moderators should have "mod panel" in the navbar and little red "crosses" allowing them to delete comments. Admins should be able to delete posts, etc. The only common element that appears on every page is the navbar. Thus, I have created four basic templates: logged.html, not-logged.html, mod.html and admin.html. Now, let's say that I need the index page to look differently for all types of users - this leads to not-logged-index.html, logged-index.html, mod-index.html, admin-index.html Then, I repeat the same routine for all pages that need to be altered depending on the user. My attempt solves this problem, but the number of templates escalates very quickly. Is there a better way to tackle this? -

Do I even need Django?
I'm currently building a website where vendors from my city can authenticate and post their products, so users can search and buy them. I started building the website with Django; in the meantime, I was taking a beautiful ReactJS 30+ hours online course and learning how much you can do with it: not only pure frontend, e.g. Routing, GET/POST requests, Forms and validation, Authentication. My initial idea was building the website with Django Rest (backend) AND React (frontend), but now I have a question: Can I build my buy&sell website with React ONLY? (maybe using some pre-made backend networks like Firebase to save/fecth data to/from a database, to save time). In your opinion would I need some backend functionalities which would be impossible/inconvenient to implement with React, Firebase or other services? Please consider that I'm talking about a quite standard buy&sell website with authenticated vendors and buyers. Thank you very much for any advice. -
jquery accordion cutting off buttons
