django.db.utils.ProgrammingError: relation "#" does not exist
Hi I made some changes to my Django app, and migrating them gives the error message-- django.db.utils.ProgrammingError: relation "#" does not exist Changing my database server works, but I have a lot of data on my original server which I can't lose. Is there any way around it? I have been on this for hours without any solution. -
Is there a way to disable throttling while using Pytest in Django?
Problem: I want to figure out a way to disable throttling when running my tests with pytest -vv Details: I have this default throttling policy in my settings.py file: 'DEFAULT_THROTTLE_RATES': { 'anon': '100/day', 'user': '1000/day' } I also have this fixture in my confest.py which returns an error whenever I exceed the limit of requests: def get_token(user, client): response = client.post( "/email-login", {"email":user.email, "password": "B9vX95phJDi3C4"}, ) return { "HTTP_AUTHORIZATION": f"Bearer {response.json()['token']['access']}" } What I have tried: I have attempted to use the solution in this GitHub Issue: https://github.com/encode/django-rest-framework/issues/1336, but it doesn't work in my case. -
Javascript/Django: change icon on dynamically created element based on query value or click
I have tried couple of ways to get icon to change on a button, that has been created with for loop on page load. Here is my element: {% for i in data %} <div class="accordion"> <div style="margin-left: -10px;"> <a href="#collapse{{ i }}", class="btn", role="button", data-bs-toggle="collapse" id="btn-collapse_{{ i }}"> <i class="material-icons" style="vertical-align: middle;">expand_more</i> <label style="vertical-align: middle;">{{ i }}</label> </a> </div> </div> {% endfor %} Here is my function to change the icon: <script> $(document).ready(function(){ $('#btn-collapse_{{ i }}').on('click', function () { var thisElement = $(this); var anchorElement = thisElement.find("i"); if(anchorElement.text() === "expand_less"){ anchorElement.text('expand_more'); } else { thisElement.find("i").text("expand_less"); } }); }); </script> I've also tried changing the color in in another instance. Heres the element: <tbody> {% for i in data %} <tr style="vertical-align: middle;"> <td><a href="#">{{ i }}</a></td> <td>{{ i.data1 }}</td> <td><a href="#">{{ i.data1 }}</a></td> <td style="text-align: center;"> <button class="btn", id="btn-{{ i.data2 }}"> <i class="far fa-check-circle"></i> </button> </td> <td style="text-align: center;"> <button class="btn", id="btn-{{ i.data3 }"> <i class="far fa-check-circle"></i> </button> </td> </tr> {% endfor %} </tbody> And here is the function: <script> $(document).ready(function(){ var data_button = document.getElementById("btn-{{ i.data2 }}"); if({{ i.data2 }} == 'None'){ data_button.style.color = "#858796"; } else { data_button.style.color = "#1cc88a"; } }); </script> Data that is being queried … -

Django: How to order by model field name, then by its reverse queryset's first entry and field?
I'm using Postgres as the db backend. I have a Load that has multiple Stops, which each Load assigned to a Carrier. Each Stop has an appointment through a DateTimeField. I'm trying to sort all Loads by Carrier's company_name, then by the Stop's appointment. Table to illustrate Shipment # | Carrier | 1st Appointment Time 10001 | ABC Freight | 01/01/2023 17:00 10002 | ABC Freight | 01/01/2023 20:00 90001 | XYZ Freight | 01/01/2023 08:00 90002 | XYZ Freight | 01/01/2023 11:00 First solution from the shell: from app.models import Load Load.objects.all().order_by('carrier__company_name', 'stops__appointment') Problem: It returns duplicate entries of the Loads queryset.

DRF's not calling post() method when receiving POST request
I have a viewset like this: class MyViewSet(CreateAPIView, RetrieveModelMixin, ListModelMixin, GenericViewSet): queryset = MyModel.objects.all() serializer_class = MySerializer def post(self, request, *args, **kwargs): import pdb; pdb.set_trace() class MySerializer(serializers.HyperlinkedModelSerializer): class Meta: model = MyModel fields = ['id', 'field1', 'field2'] #only field1 is required in the model The GET requests for list, and retrieve works perfectly. When I make a POST request, sending the field1 I get a status 201 and a new record is added to the database, so it works too. But my method MyViewSet.post() that should overwrite the same one from generics.CreateAPIView never gets called. Not only that, but I've tried to add the pdb.set_trace(), literally inside the generics.CreateAPIView.post() and in the CreateModelMixin.create() functions and neither stopped once I made the POST request. So something else is handling this POST request and inserting into the DB, I just don't know what. And how can I overwrite it, so I can customize what should be done with a post request? PS.: Also, I don't think it's a routing problem, my urls.py: from rest_framework import routers from myapp.views import MyViewSet, AnotherViewSet router = routers.DefaultRouter() router.register(r'route_one', MyViewSet) router.register(r'route_two', AnotherViewSet) -

It's always returning to me a true ordered order, but I want to just take that have the ordered false, because I want to show in my cart an empty cart after making the checkout POST for redirect to home o other view and update for me to an empty new cart, pls if someone can help me even with an article post about it and explain to me what I'm doing wrong, thanks! -
Django Middleware: RecursionError when accessing `self.request.user` in database query wrapper
I'm testing my database query middleware (Django docs here) on a sample django app with a Postgres db. The app is the cookiecutter boilerplate. My goal with the middleware is simply to log the user ID for all database queries. Using Python3.9 and Django3.2.13. My middleware code is below: # Middleware code import logging import django from django.db import connection django_version = django.get_version() logger = logging.getLogger(__name__) class Logger: def __init__(self, get_response): self.get_response = get_response def __call__(self, request): with connection.execute_wrapper(QueryWrapper(request)): return self.get_response(request) class QueryWrapper: def __init__(self, request): self.request = request def __call__(self, execute, sql, params, many, context): # print(self.request.user) return execute(sql, params, many, context) If print(self.request.user.id) is commented out, everything works fine. However, I've found that uncommenting it, or any type of interaction with the user field in the self.request object, causes a Recursion Error: RecursionError at /about/ maximum recursion depth exceeded Request Method: GET Request URL: http://127.0.0.1:8000/about/ Django Version: 3.2.13 Exception Type: RecursionError Exception Value: maximum recursion depth exceeded Exception Location: /opt/homebrew/lib/python3.9/site-packages/django/db/models/sql/query.py, line 192, in __init__ Python Executable: /opt/homebrew/opt/python@3.9/bin/python3.9 Python Version: 3.9.13 In the error page, that is followed by many repetitions of the below error: During handling of the above exception ('SessionStore' object has no attribute '_session_cache'), another exception … -

How do I re-use <option> data in HTML forms? (Django) (DRY)
I'm generating an HTML response via Django with a large set of forms, and one of the form fields is a <select> with many (1,000+) <option>s in the queryset. Due to repeating the <option>s for each form, the HTML response is egregiously long. I've used pagination to reduce the amount of HTML rendered in each response, but this isn't optimal for the particular application. Is it possible to render the <option>s once on the HTML response and reference it in each form field without rendering it again? -

Convert a list of dictionaries to a dictionary of dictionaries

docker container for Django hangs when updating mounting sources
As part of a course I am currently passing there is a situation when following combination is used: A docker container is created for very standard scenario: One for Django, second one for Postgresql database and then a compose file is managing all this stuff. And the sources are actually mounted using the docker-compose volumes. The entire application I created during the course is available in my github: https://github.com/arsenhakobyan/recipe-app-api The problem I faced is with running django test command each time when I update any source file. steps to reproduce the issue I have: build images with docker-compose build run the following command: docker-compose run --rm app sh -c "python manage.py test" The process should run as expected. Edit any file (e.g. app->user->tests->test_user_api.py) and save the changes run the command from step 2. the process hangs at this point in my case and I can not even force to remove the docker containers, even tried to deactivate some endpoints from the network that is connected with that containers (I think that could help when I read some of the error messages). The only way to continue work is to restart the docker exe on my machine. Let me know if … -
How to connect two databases in django for local and remote servers?
guys. I have a database, which I deployed on Heroku. DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql', 'NAME': 'd7mj3h2mco40v9', 'USER': 'fwla1qyxgxrrqk', 'PASSWORD': get_secret('DB_PASSWORD'), 'HOST': 'ec2-54-174-73-136.compute-1.amazonaws.com', 'PORT': '5432', } } The problem is when I add comments objects on a local machine, they automatically downloaded to the remote database. It's not convenient. I want to create, for example, a local database which will save all migrations or changes of my models, but not downloaded into a remote server. And when I need to download the data, I will do something and the changes are to appear on a remote database. What do I need to do for this? How to make the right migrations and then work with them? I'm newbie, please don't advice complicated things I can't understand :) -
