DjangoCMS TypeError: from_db_value() missing 1 required positional argument: 'context' after upgrade to 3.7.2 w/ Django 3.0.1
I had a working DjangoCMS application running DjangoCMS 3.7.1 and Django 2.2, however after I just bumped the DjangoCMS version to 3.7.2 and with it, Django to 3.0.1, I am now getting a render error on a page that I have a simple list view.

Environ variables in .env file in Django and docker
Hi I'm using Docker to build a Django web application for production via Docker-Compose and it uses the .env.prod file for the environmental variables. The docker-compose file works fine and deploys to a server with no issues via CI/CD on GitLab. I was hoping to use the same kind of structure but just have a .env.dev file so I don't have to modify the settings file in any way. The problem I'm having is I can't find how to set environment variables from an external file in development mode. The only workaround I can see is having a local_settings.py file which I was hoping to avoid. Example of what I'm trying to achieve below in the settings.py file. DEBUG = int(os.environ.get("DEBUG", default=0)) with a .env.dev file. DEBUG=1 DJANGO_ALLOWED_HOSTS=localhost 127.0.0.1 149.28.188.180 [::1] Thanks in advance. I'm sure I'm missing something easy. -
Create Django HTML Button that will Change BooleanField in Model

This way, no other users may be able to take on the job. Are there any suggestions? My database is SQLite. -
Django search view not generating html page I set
I am having trouble getting my search form to work in Django. When I search anything in the search bar I have set, I get an html page that just has the words Search on it. It's not the html page I set, though. My search template is in my projects templates directory. I am trying to search through my blog posts, and have attached my views and urls code. This portion of my base template is within a navbar I grabbed from a sample Bootstrap blog template. This is the sample template. I've changed some things within my form. base.html ... <form class="form-inline my-2 my-lg-0" action="{% url 'search' %}" method="GET"> <input class="form-control mr-sm-2" type="search" name="q" placeholder="Search blog posts..."> <button class="btn my-2 my-sm-0" type="submit">Search</button> </form> ... Nothing within my blocks shows up when I view it. The tags <p>TEST</p> and <p>Is this working?</p> are not showing up. Neither is the block for the jumbo_content. I have set those correctly in my base.html, because they work with my other pages. It's just the search page it doesn't work on. search.html {% extends "base.html" %} {% load static %} {% block jumbo_content %} <h1 class="display-4">Search Results</h1> {% endblock %} {% block page_content … -
PostgreSQL text search in Django not working as expected
I am implementing a search function for my API to return the object's properties when requested. So far I have tried to use Full Text Search which is usable but it has these annoying things: words have to be spelled correctly for the results to be returned and partial search, for example "appl" instead of "apple", won't work. I have also tried Trigram Similarity but it failed for long sentences. How do I implement a search function that is both accurate and fuzzy in Django? This works This won't work This is my views.py from django.shortcuts import render from rest_framework.response import Response from rest_framework import status from rest_framework.decorators import api_view from .models import Object_Locations from .serializers import Object_LocationsSerializer from django.contrib.postgres.search import SearchVector, SearchQuery def index(request): return render(request, 'main/base.html', {}) @api_view(['GET',]) def LocationsList(request): if request.method == 'GET': vector = SearchVector('name', 'desc', 'catergory') query = request.GET.get('search') if query: locations = Object_Locations.objects.annotate(search=vector,).filter(search=SearchQuery(query)) else: locations = Object_Locations.objects.all() serializer = Object_LocationsSerializer(locations, many=True) return Response(serializer.data) -
Does it possible that transaction.atomic does not work as expected?
This is a DRF API View for entry like. When someone like a entry, i will insert a like record into table entry_like, and plus by 1 to field likes_num in another table entry. But, something went wrong that some of the count of entry_like records corresponding to one entry is less than the field likes_num in table entry. I do not know why it does not work as expected even the post method is with decorator transaction.atomic on. Are there some cases that the decorator transaction.atomic does not run as expected? -

How to add a value to an existing model record with the use of Django Forms?
I'm trying to make a form that adds points to a user's account. This form chooses which user and it should add it based on the value added. I don't know what I did wrong. No hints in the terminal to show what I did wrong. I just doesn't submit. The only indication that I screwed up is it shows that !form.is_valid based on the error message that I set.

Points has been added!') instance.points += addpointForm.add_point_field instance.save() else: messages.error(request, 'Oh no! Points has an error!') form = addpointForm() return render (request,'users/addpoints.html',{'form':form}) I just some help to point me in the right direction. Any help is appreciated thank you. -
Two foreign keys, only one can be not null at a time
I have a database table with two foreign keys pointing to two different tables. The business logic requires an "either or" relationship; only one foreign key can be NOT NULL at any given time. Here are the four possible states the foreign keys can hold based on the business logic: NULL, NULL - okay number, NULL - okay NULL, number - okay number, number - invalid business logic I'm using Django, and I know I can write some onSave() checks that will handle this, but that feels hackish. Is there a better method to deal with this business logic? -
Django AUTH_USER_MODEL refers to model '%s' that has not been installed

I'm pulling a dictionary from an API call, when I pull URL information it quotes and brackets around them

What is the most efficient way to make Post previews on Django?
I am making a Blog where I want for the home page to show only the first 100 characters of each post. My point is to make better use of space. If a person want to read a post, that person can just click to read it. I have some ideas on how to do it, but I think they won`t work or are inefficient: To create a subclass on blog models.py where I would inherit the Post class, save the first hundred characters of each content to a list and make a loop to save each list on the database; To place a instruction on blog views.py 'FirstPageView' class where it would only exhibit the first hundred characters. The 'Post' and 'FirstPageView' mentioned classes are as follows: on 'blog/views.py': from django.views.generic import ListView class FirstPageView(ListView): model = Post template_name = 'Blog/home.html' context_object_name = 'posts' ordering = ['-date_posted'] paginate_by = 6 on 'blog/models.py': from django.db import models from django.utils import timezone from django.contrib.auth.models import User from django.urls import reverse class Post(models.Model): title = models.CharField(max_length=100) content = models.TextField() date_posted = models.DateTimeField(default=timezone.now) author = models.ForeignKey(User, models.SET_NULL, blank=True, null=True) def __str__(self): return self.title def get_absolute_url(self): return reverse('post-detail', kwargs={'pk': self.pk}) So what would be … -
Do I have to use Redux with React for authentication?
This may be a stupid question. So, I am using Django for my backend and React for my frontend. The goal is to only show the objects that belong to the user that is making the request.
