Django: Built-in login fails with existing User
I have a question regarding django built in authentication system. I'm following this DjangoDoc. So I added the URLS in my urls.py: from django.urls import include, path from .views.views_user import * from rest_framework.urlpatterns import format_suffix_patterns urlpatterns = [ path('accounts/', include('django.contrib.auth.urls')) ] urlpatterns = format_suffix_patterns(urlpatterns) And here is my login.html: {% extends "base.html" %} {% block content %} {% if form.errors %} <p>Your username and password didn't match. Please try again.</p> {% endif %} {% if next %} {% if user.is_authenticated %} <p>Your account doesn't have access to this page. To proceed, please login with an account that has access.</p> {% else %} <p>Please login to see this page.</p> {% endif %} {% endif %} <form method="post" action="{% url 'login' %}"> {% csrf_token %} <table> <tr> <td>{{ form.username.label_tag }}</td> <td>{{ form.username }}</td> </tr> <tr> <td>{{ form.password.label_tag }}</td> <td>{{ form.password }}</td> </tr> </table> <input type="submit" value="login"> <input type="hidden" name="next" value="{{ next }}"> </form> {# Assumes you setup the password_reset view in your URLconf #} <p><a href="{% url 'password_reset' %}">Lost password?</a></p> {% endblock %} So it renders correctly the template with the login form.

Django intercept adding objects to Many-to-Many field
I'm building a Django app and I want to overwrite the default adding to many-to-many field behaviour. Say I want to print out something when a relationship between 2 objects is created. class Foo(Model): ... class Bar(Model): foos = ManyToManyField(Foo) Is there anywhere where I can overwrite the add method of the many to many relationship manager class? Something like class ???: def add(self, obj, *args, **kwargs): super().add(obj, *args, **kwargs) print(f"{obj} added") and the expected output should be >>> foo1 = Foo.objects.create(...) >>> bar = Bar.objects.create() >>> bar.foos.add(foo1) foo1 added Thanks everyone. -

Executing two celery workers from one line
I am working on a project for my university within a team where I was mostly working on the frontend and some basic django models, so I am not so familiar and eloquent with django-celery and I also did not set it up. At first we were using one celery worker, but I had to add one more so I was able to finish a user story. I am currently running two workers with one in a terminal each like this: exec celery -A my_proj --concurrency=1 worker exec celery -A my_proj --concurrency=1 worker -B -Q notification While i run those two my project works, but I need these to start from one line. So: How do I get those two into one line for a script? So far I've tried around this: exec celery multi start celery -A my_proj --concurrency=1 notification -A my_proj --concurrency=1 -B -Q notification But it stops my project from functioning. Any help is appreciated, thank you! -
Can't Authorize when i try to login to my django project from iphone
I have created a website using Django (Django-rest-framework, django-rest-knox), ReactJS and redux together. I have run the server from 0.0.0.0:8000 to reach the project from my iPhone and test there. The Website has been loaded however when I try to log in, it can not authorize and gives 401 error. On the other hand, I can authorize without any problem from browsers on PC (chrome, opera, firefox etc.) and android devices. I have also installed Opera Mini to my iPhone and, again I couldn't authorize it. I don't know which part of my code I have share. I also couldn't find any information about this issue. I would be glad if anyone can help me. -

Display data of a searched item using Django
I currently have a search bar. It searches clients that have filled a form, using first and last names, the search provides a list with the names being links to the client's page. I am struggling to display that specific person's data, the model has about 20 fields, it would need to display all. How could I retrieve the data of a single person and display all the data from the model? At present the page comes up blank, the URL displays the correct client id though. Thank you in advance. -
405 error when testing an authed django-rest-framework route
I'm testing a CreateAPIView with an APITestCase class. Things are working as expected as an anonymous user, but when I login() as a user, I get a 405 HttpResponseNotAllowed exception. I'm able to successfully create an object while authed as a user through the django-rest-framework web frontend. I'm using djangorestframework version 3.9.4 and Django 1.11.29. Here are the main parts of the code, for a general idea of what I'm doing: class SherdNoteCreate(CreateAPIView): serializer_class = SherdNoteSerializer def post(self, request, *args, **kwargs): data = request.data.copy() data['asset'] = kwargs.get('asset_id') serializer = SherdNoteSerializer(data=data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) class SherdNoteTests(APITestCase): def test_create_sherdnote_on_own_asset(self): # Removing this auth block allows the test to pass self.u = UserFactory(username='test_user') self.u.set_password('test') self.u.save() login = self.client.login(username='test_user', password='test') assert(login is True) asset = AssetFactory(primary_source='image', author=self.u) url = reverse('sherdnote-create', kwargs={'asset_id': asset.pk}) data = { 'title': 'note title', 'body': 'note body' } response = self.client.post(url, data, format='json') # This fails with a 405! self.assertEqual(response.status_code, status.HTTP_201_CREATED) I've been having trouble tracking down why this is happening. Let me know if you have any ideas. -
Using Django how can I get a set of records where the value used for filtering is to a many-to-many field
Assuming I have data that resembles: id | value | m2m__created | m2m__value ---+-------+--------------+----------- 1 | 10 | 2020-03-14 | 0 1 | 10 | 2020-03-21 | 5 2 | 20 | 2020-03-14 | 10 3 | 30 | 2020-03-14 | 20 what I want after filtering is: id | value | m2m__created | m2m__value ---+-------+--------------+----------- 1 | 10 | 2020-03-21 | 5 2 | 20 | 2020-03-14 | 10 3 | 30 | 2020-03-14 | 20 I'm trying to use something like this: Foo.objects.filter( foo_m2m__created__lte=start_date, ).order_by( 'id', '-foo_m2m__created', ).annotate( recently_created=Max('foo_m2m__created'), ).values( 'id', 'value', 'foo_m2m__created', 'foo_m2m__value', ) unfortunately, what I get is this: id | value | m2m__created | m2m__value ---+-------+--------------+----------- 1 | 10 | 2020-03-14 | 0 2 | 20 | 2020-03-14 | 10 3 | 30 | 2020-03-14 | 20 I've tried adding another .filter(foo_m2m__created=F('recently_created')) following the annotation, but the same thing happens. -
How to create tuple expressions in Django database queries?
I have some table ports(switch_ip, slot_number, port_number, many, more, columns) and would like to achieve the following PostgreSQL query using Django: SELECT switch_ip, array_agg((slot_number, port_number, many, more, columns) ORDER BY slot_number, port_number) info FROM ports GROUP BY switch_ip ORDER BY switch_ip Using django.contrib.postgres.aggregates here's what I got so far: Port.objects \ .values('switch_ip') \ .annotate( info=ArrayAgg('slot_number', ordering=('slot_number', 'port_number')) ) \ .order_by('switch_ip') I am unable to include more than one column in the ArrayAgg. None of ArrayAgg(a, b, c), ArrayAgg((a, b, c)), ArrayAgg([a, b, c]) seem to work. A workaround could involve separate ArrayAggs for each column and each with the same ordering. I would despise this because I have many columns. Is there any nicer workaround, possibly more low-level? I suspect this is no issue with ArrayAgg itself but rather with tuple expressions in general. Is there any way to have tuples at all in Django queries? For example, what would be the corresponding Django of: SELECT switch_ip, (slot_number, port_number, many, more, columns) info FROM ports If this is not yet possible in Django, how feasible would it be to implement? -
Web Design (Payment Processing Project) Plan Question:
I am creating a plan to build a payment processing web page (under my domain) where a user can access the page and use a 3rd party app to pay me (payment through the Plaid and Dwolla application). As of now, I do not need to track the user's information. I was thinking of using React on the frontend and Django on the backend. I have 4 questions: Do I only need a frontend, as I am not storing the user's information? Or is it best to have both backend and frontend for organization? Would you recommend using React, Django, and Heroku? Any recommendations on tutorials to follow (youtube, docs, etc)? Any tips on how to integrate Plaid/Dwolla? -

Render row group headings with django-tables2
I'm porting a PHP/PostgreSQL/DataTables project over to Django 3. I don't use DataTables for anything too fancy except for the rowGroup extension that groups the dataset into sections according to one of the fields in the dataset. Here's an example of what I'm talking about. I'd like to keep this simple, so I'm hoping to using django-tables2 to accomplish the same thing. Is it possible to render a table using django-tables2 that will group the rows in the resulting table according to values in a column in the dataset? -
