Pytest: update Django DB in tests
I work on a library for Django using pytest 3.0.6 and pytest-django 3.1.2. I have this very simple test failing, and I don't understand what happen: # test_mytest.py import pytest from django.contrib.auth.models import Permission from django.contrib.contenttypes.models import ContentType @pytest.mark.django_db def test_user_has_perm(django_user_model): # Create a new user john_doe = django_user_model.objects.create_user('johndoe', email='jd@example.com', password='123456') # Get or create the permission to set on user user_ct = ContentType.objects.get(app_label='auth', model='user') p, _ = Permission.objects.get_or_create(content_type=user_ct, codename='delete_user', name="Can delete user") # User don't have the permission assert john_doe.has_perm(p) is False # Set permission to user john_doe.user_permissions.add(p) assert john_doe.has_perm(p) is True # ---> FAIL When I put breakpoint to stop in the middle of the test, I see the Sqlite DB file is NOT on my disk.

Confirmation Email Sending via django-simple-email-confirmation
I am writing a code for sending a confirmation email to the one who has registered. I want to use django-simple-email-confirmation library, and I want to know how to manage my views.py file.

How to set resource name on an ad-hoc method of Viewset in Django Rest Framework JSON API?
I am using Django 1.10 with DRF 3.5 and Django Rest Framework JSON API 2.1.1. I have a Viewset that follows the normal pattern of a ModelViewset, but I need to add an ad-hoc as follows: class EnvoiViewSet(viewsets.ModelViewSet): queryset = Envoi.objects.none() serializer_class = EnvoiSerializer filter_class = EnvoiFilter ordering_fields = ('date_envoi',) # .... @decorators.list_route(methods=['post']) def ad_hoc_method(self, request): #.... My problem is that I want to change the resource name for the method but not for the class. Is this possible with a decorator or something like it ? For example: @decorators.list_route(methods=['post']) @resource_name('SpecialEnvoi') def ad_hoc_method(self, request): #.... -

How insert form in base.html
This is my site: http://oriflame.pythonanywhere.com/ Each page is formed of two patterns: base (template for all page) and index, the main page. At the base you want to paste the application form for the call. But here's the problem: I want to insert in the parent template form made in forms.py. You can probably copy all views "form = CallForm ()" and the correct context, but maybe there is another solution? -

Django-Celery in production?
So I've been trying to figure out how to make scheduled tasks, I've found Celery and been able to to make simple scheduled tasks. To do this I need to open up a command line and run celery -A proj beat for the tasks to happen. This works fine in a development environment, but when putting this into production that will be an issue. So how can I get celery to work without the command line use? When my production server is online, how can I make sure my scheduler goes up with it? Can Celery do this or do I need to go down another method? -
How to display a dropdown field __str__ in Django templates?
I've got a ModelForm where I can display either a foreignkey field which comes as a dropdown list ({{ form.auto_part }}) or the value or the ID of that foreignkey field which comes as a number ({{ form.auto_part.value }}). But I want to show the __str__ value of the foreignkey field.

How to render a form from another django app including error handling
on my landing page / home page I want to add a contact form and a subscribe to newsletter form. Since I want to keep the logic for both forms in separate apps I am wondering how I can use Django's internal form error handling in case the user does an input error. Similar to the standard form error handling I want that the landing page is reloaded with the errors next to the form fields. This is fairly easy if the logic stays within the same app but I can't wrap my head around it how to do this when the logic is in another app. Here is the basic layout: project/views.py: from django.views.generic.base import TemplateView from contact.forms import ContactForm from newsletter.forms import NewsletterForm class HomeView(TemplateView): template_name = "home.html" contact_form = ContactForm() newsletter_form = NewsletterForm() title = "Home" contact/forms.py from django import forms from .models import Contact class ContactForm(forms.ModelForm): class Meta: model = Contact fields = ['contact_name', 'contact_email', 'content'] widgets = { 'contact_name': forms.TextInput(attrs={'placeholder': 'Your name'}), 'contact_email': forms.TextInput(attrs={'placeholder': 'Your Email address'}), 'content': forms.Textarea(attrs={'placeholder': 'Your message'}), } contact/models.py from django.db import models class Contact(models.Model): contact_name = models.CharField(max_length=120) contact_email = models.EmailField() content = models.TextField() timestamp = models.TimeField(auto_now_add=True, auto_now=False) def __str__(self): return … -

Can't log in to Django admin locally or in prod
I'm having two problems with my new Django admin, but I'm not sure if they're related so I don't want to split them into two questions just yet. The site is live and working--I went to the admin for the first time and got a csrf error. So I went back to my dev site and tried to log in, and it told me that my username/password was incorrect. I did python manage.py createsuperuser and still was unable to log in with the new user (credentials were definitely correct). Here are some of my settings files based on what seemed relevant from other askers. MIDDLEWARE_CLASSES = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.auth.middleware.SessionAuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', ] SESSION_COOKIE_SECURE = False CSRF_COOKIE_SECURE = False CSRF_COOKIE_HTTPONLY = False X_FRAME_OPTIONS = "DENY" Note that the three Boolean values had previously been set to True. I changed them to False to experiment, and cleared cookies. No change. -

Django : get data and edit in the same form, edit in one place
I've been working to make an edit form where shows data saved in db and user can edit it like jsp model and view.

User Interface/ Front End with Djngo
I'm in the process of developing a website for travel planner. It is my first time to use a web framework which will be Django, I have no idea about it, but I'm in the learning process. I'm trying to figure out how I can integrate my front end or the HTML, CSS, And java script into dingo. I mean I'm going for Django as a back end and I don't know if Django has the ability to facilitate a front end design, I'm concerned a lot about design, so I want to feel free to play around with the front end. So, is there is anyway that I can code my own pages in notpad++ and add them to djngo as web pages, or any platform I should use in order to integrate the fron end with Django? Just because prior to my research about Django the front end templating that Django provides has other scripts than css and html and I honestly have no idea what does that mean! So a little feedback about this would really make a huge help! Thanks in advance, Maryam -
Django Wagtail Project - Conflict with django.contrib.sites (using django-allauth)
I'm running into issues when adding a 3rd party 'user accounts' app to a Wagtail project. Most 3rd party user account apps (such as django-alluth) require django.contrib.sites as a dependency. When I include the django-allauth dependencies (including the required django.contrib.sites) in INSTALLED_APPS, along with wagtail.wagtailsite app, I run into issues with the site loading correctly (static files don't load correctly, for example). I am unable to track down exactly what isn't loading correctly, but from what I can tell, it is a runtime conflict between the wagtail 'sites' app and the django 'sites' app. It seems like there should be a way to have wagtail and django-allauth running side-by-side... Does anyone have django-alluth and wagtail working nicely together? Is it possible and what did you need to do? Any tips or examples of django-alluth and Wagtail working together are greatly appreciated. Versions: Django 1.10.1, Wagtail 1.8 -

How to add function result to <p> tag in Django

Django: How can I manage Redis-server storage?
