AttributeError: module 'django.db.migrations' has no attribute 'RunPython'
I get this error whenever I try running my server, migrating, or running any Django commands. All my previous Django projects also show the same error, but they were working fine before.

django-q task manager is not working correctly if there is no request in system
Anyone using django-q task scheduler: https://github.com/Koed00/django-q (Not the database related Q library) I'm scheduling cron task which will trigger some jobs. But my main problem is, tasks starts working 30-60 mins later than i scheduled if there is no new request in server. After lots time when i refresh page , it's starts running immediately. Even i set timeout low to try if it's gonna work but it didn't. Is there any conf that i can set for this issue ?

Getting "IntegrityError FOREIGN KEY constraint failed" when i am trying to generate the invoice from booking table
I am trying to generate an invoice from the booking table. I have created a separate table for invoices and declared a foreign key for the booking table and package too.

Collectstatic fails with Django 4.0 [duplicate]
I am unable to run python manage.py collectstatic with Django 4.0. Error is ....min.js references a file which could not be found .....min.js.map I believe this is due to Django 4.0 collectstatic having added manifest_storage: https://docs.djangoproject.com/en/4.0/ref/contrib/staticfiles/ This leads to error. I try to disable this by WHITENOISE_MANIFEST_STRICT = False but this does not have any affect. I run site on Heroku so I have django_heroku.settings(locals()) at end of settings.py file. Tried to fix this by adding an empty file with touch to location indicated in error message. Error is gone, but next .map-file is missing. No sense to manually fix. The question - how to disable finding .map -files in manage.py collectstatic in Heroku-setup? -

Same code, same database, different results on testing server and local server
My local environment and my testing environment are both connected to the same database engine (postgresql) and have the same Django settings. In my TableA, I have some duplicate rows and I only want to get the ones that belongs to "category_1" with distinct "field1" values. So I do: result = TableA.objects.filter(category='category_1').distinct('field1').order_by('field1') This creates the query SELECT DISTINCT ON ("TableA"."field1") "TableA"."id", "TableA"."category", "TableA"."field1" FROM "TableA" WHERE "TableA"."category"= "category_1" ORDER BY "TableA"."field1" The result looks correct on the local, but when I test it on my testing server the result still includes the rows that have the same "field1" values. What could possibly go wrong?? -

Running makemigrations in Django package test case with tox
I've got a Django package, and I want to run makemigrations --check --dry-run --noinput in a test case (not using pytest; standard Django test runner). I tried just running call_command, but, with sqlite, that in turn uses the in memory db. So if there was supposed to be a migration, the db/django wouldn't know about it. I.e., when I do this, the command just says that no changes were detected. If you try doing django-admin makemigrations, you'll get an "apps not loaded" issue. Anyone have an idea of what we can try to do? Maybe threads? Ref this is taking place in django-oauth-toolkit -
Django drag drop help please
I'm looking for help with a drag-n-drop feature for updating a table in my Django model. I need to be able to drag items (a list of model objects) between 3 baskets and update the item's basket type in the model. My model contains food items and the status of these items. So the food.names will be the items dragged and 3 baskets are the food.status: 'don't have', 'have', 'need to buy'. Just like this example: https://www.javascripttutorial.net/sample/webapis/drag-n-drop-basics/. <!DOCTYPE html> <html lang="en"> <head> <style> #div1, #div2, #div3 { float: left; width: 100px; height: 35px; margin: 10px; padding: 10px; border: 1px solid black; } </style> <script> function allowDrop(ev) { ev.preventDefault(); } function drag(ev) { ev.dataTransfer.setData("text", ev.target.id); } function drop(ev) { ev.preventDefault(); var data = ev.dataTransfer.getData("text"); ev.target.appendChild(document.getElementById(data)); } </script> </head> <body> <h2>Drag and Drop</h2> <p>Drag the items back and forth between the three div elements.</p> {% for row in all_food %} <div id="div1" ondrop="drop(event)" ondragover="allowDrop(event)"> {% if row.status_type == 'have'%} <ul> <li><a href="/" draggable="true" ondragstart="drag(event)" id="drag1" width="88" height="31">{{row}}</a> </ul> {% endif %} </div> <div id="div2" ondrop="drop(event)" ondragover="allowDrop(event)"></div> <div id="div3" ondrop="drop(event)" ondragover="allowDrop(event)"></div> {% endfor %} </body> </html> The code above comes out as 33 boxes with the items in the for loop scattered among … -
How to publish changes to Docker images in Github Actions

IntegrityError on migration using Geodjango + Spatialite
I have a Model CoordenadasPonto that uses one PointField from django.contrib.gis.db.models in an app called mc. When I try to migrate a modification of this Model, Django raises: django.db.utils.IntegrityError: The row in table 'geometry_columns_statistics' with primary key 'CONSTRAINT' has an invalid foreign key: geometry_columns_statistics.f_table_name contains a value '**new__**mc_coordenadasponto' that does not have a corresponding value in geometry_columns.f_table_name. It doesn't matter if I modify the PointField or other fields. It seems every time I modify the Model, Django try to copy all the data to a new Table in Database using new__ plus original table name. After that, I guess Django would delete/drop the original table and rename new__ to the original name. But due to the IntegrityError, this never happens. It seems the problem is with GIS/Spatialite because some data is linked with the GIS table geometry_columns_statistics not migrated in accordance. I tried to modify directly the geometry_columns_statistics in the sqlite file, but other dependencies problems came out. -
How do I get Django to not add carriage returns in a Textarea in the admin UI?

how to access django database on the remote site from a local script?
I have the following code in a script: import django django.setup() This loads my project settings for local development but what I actually want is to load the server's settings (specifically the database access). What I tried? I created another file settinge_remote.py (same folder as settings.py) and setting the DATABASES dictionary to hold the remote server host/ip. but the code: import django django.setup() os.environ.setdefault("DJANGO_SETTINGS_MODULE", "my_project.settings_remote") has no effect (I also moved the setting_remote line in first place).

I have a custom abstract base user and basic login with knox view, I made some simple tests to the register and login process, however all the testcases fail to assertion error:401!=200 and when I use pdb.set_trace to know the sent data it always has that error (Pdb) res <Response status_code=401, "application/json"> (Pdb) res.data {'detail': ErrorDetail(string='Authentication credentials were not provided.', code='not_authenticated')} Here is the test setup from rest_framework.test import APITestCase from django.urls import reverse class TestSetUp(APITestCase): def setUp(self): self.register_url = reverse('knox_register') self.login_url = reverse('knox_login') self.correct_data = { 'email':"user@gmail.com", 'password': "Abc1234#", } self.wrong_email_format = { 'email': "user@gmail", 'password': "Abc1234#", } self.missing_data = { 'email':"user@gmail.com", 'password':"", } self.wrong_password_format = { 'email': "user@gmail.com", 'password': "123", } return super().setUp() def tearDown(self): return super().tearDown() and the test_view from .test_setup import TestSetUp import pdb class TestViews(TestSetUp): #register with no data def test_user_cannot_register_with_no_data(self): res = self.client.post(self.register_url) self.assertEqual(res.status_code,400) #register with correct data def test_user_register(self): self.client.force_authenticate(None) res = self.client.post( self.register_url, self.correct_data, format="json") #pdb.set_trace() self.assertEqual(res.status_code,200) #register with wrong email format def test_register_with_wrong_email_format(self): res = self.client.post( self.register_url, self.wrong_email_format) self.assertEqual(res.status_code, 400) # register with wrong password format def test_register_with_wrong_password_format(self): res = self.client.post( self.register_url, self.wrong_password_format) self.assertEqual(res.status_code, 400) #register with missing_data def test_register_with_missing_data(self): res = self.client.post( self.register_url, self.missing_data) self.assertEqual(res.status_code, 400) #login with correct Credentials … -
Django / app import problem from submodule
I'm writing my own Django app, and trying to import submodule from my core library like that: INSTALLED_APPS = [ 'django.contrib.admin', ... 'core.login', ] And interpreter gives me: django.core.exceptions.ImproperlyConfigured: Cannot import 'login'. Check that 'core.login.apps.CustomloginConfig.name' is correct. So login.apps looks like that from django.apps import AppConfig class CustomloginConfig(AppConfig): name = 'login' Are there any rules how I can edit this files to start Django properly? -
