django not showing RAW SQL with sqlmigrate
I'm trying to get the RAW SQL from a migration and it only prints begin and commit. I'm modify a model, adding the middle_name field class User(AbstractBaseUser): email = models.EmailField(max_length=200, blank=False, unique=True) first_name = models.CharField( max_length=200, blank=False, verbose_name="nombre" ) middle_name = models.CharField( max_length=200, blank=True, verbose_name="segundo nombre" ) It creates the migration 0007_user_middle_name.py # Generated by Django 3.2.23 on 2024-06-10 16:15 from django.db import migrations, models class Migration(migrations.Migration): dependencies = [ ('biglifeapp', '0006_biglifesetting_new_field'), ] operations = [ migrations.AddField( model_name='user', name='middle_name', field=models.CharField(blank=True, max_length=200, verbose_name='segundo nombre'), ), ] but when I run python manage.py sqlmigrate my_app 0007 --database=default it only prints `BEGIN; -- -- Add field middle_name to user -- COMMIT; this should print something like `BEGIN; -- -- Add field middle_name to user -- alter table user add column middle_name (...) COMMIT; I saw 2 questions on stackoverflow, but none of those was the case for this case, the db does indeed change, I'm adding a new column to it For some migrations, why `sqlmigrate` shows empty, or the same SQL both directions? in this case, the --database argument is being provided Django sqlmigrate not showing raw sql -

django flatpages will show only one page
I'm trying to use flatpages in my Django application. I installed it properly as far as I can see and created 2 pages. Using the shell, when I try: >>> from django.contrib.flatpages.models import FlatPage >>> FlatPage.objects.all() <QuerySet [<FlatPage: /pages/en-US/about/privacy/ -- Privacy Policy>, <FlatPage: /pages/fr-FR/about/privacy/ -- Politique de Confidentialité>]> I can see my 2 pages. But in a template, I'm using: {% get_flatpages as about_pages %} {% for page in about_pages %} <a class="navbar-item" href="{{ page.url }}">{{ page.title }}</a> {% endfor %} And there I can see only the last page. Also when I access directly the first page using it's full URL (http://127.0.0.1:8000/pages/fr-FR/about/privacy/) it displays nicely but when I try the same with the other one (http://127.0.0.1:8000/pages/en-US/about/privacy/) I get a 404. I tried to change the name of the first page, but nothing works. Any idea??? -
Naming an abstract model Django
What is the standard for naming Django abstract classes? My team leader insists that the name of the abstract model should consist of the fields available in it. for example, IsPublishedAndCreatedAt. But My class: class BaseContentProperties(models.Model): is_published = models.BooleanField() created_at = models.DateTimeField() class Meta: abstract = True class Category(BaseContentProperties): ... class Location(BaseContentProperties): ... class Post(BaseContentProperties): ... But if there are more fields, then the name will be more, for example, IsPublishedAndCreatedAtAndPublishedAt.... Who is right?) If there are some generally established recommendations on this issue, you can send a link so that you can familiarize yourself. Thanks I described my problem above -

How to get fields names that were chosen with method "only()"?
For example, I have simple model: class Person(models.Model): id = models.BigAutoField("id", primary_key=True) first_name = models.CharField(max_length=150) surname = models.CharField(max_length=150) age = models.IntegerField() I use method only to choose fields I need: queryset = Person.objects.all().only("first_name", "age") How can I get fields names("first_name", "age") that were chosen? I tried this: queryset.query.get_loaded_field_names() But I got this error: AttributeError:'Query' object has no attribute 'get_loaded_field_names' -
js files in the admin
I load some js files in the admin using a custom admin site, let's call it custom_admin_site.html. In this template I override some blocks: {% extends "admin/base_site.html" %} {% load i18n static %} {% block extrahead %} <link rel="shortcut icon" href="{% static 'images/favicon.ico' %}" /> <script src="{% static 'admin/src-min-noconflict/ace.js' %}" referrerpolicy="no-referrer"></script> <script src="{% static 'js/htmx.min-1.9.11.js' %}"></script> {% endblock %} When I use these libraries, on the main page (/admin) they work just fine. When I override other templates, for example I have: projectname \ templates \ admin \ appname \ modelname \ change_form.html: {% extends "admin/change_form.html" %} {% load i18n admin_urls %} ... and I cannot access my libraries form here. Do I need to add something like this in my 'change_form.html`? {% block extrahead %} {{ block.super }} {% endblock %} or can I somehow make sure that other htmls also use my extended custom_admin_site.html and not the normal admin/base_site.html? Or am I approaching this the wrong way and should I define a Media subclass with the js files in the admin.py where it is needed? -

Execute callback when django.cache.set timeout is exceeded
I use Django cache with django-redis==5.0.0 like this: cache.set(f'clean_me_up_{id}', timeout=10) Storing an entry into cache, which will be cleared after timeout, works perfectly for me. What I´m trying to acheive, is to execute also some cleanup code (as a callback?) when the cache is deleted. Is there some easy way to do this as it would be extremely helpful. -
graphene-django get_node vs get_queryset
I'm currently getting acquainted with graphene-django and there's one aspect of it I'm not quite getting my head around. I would like to let my users use GraphQL to query our database. I would like them to be able to filter their results by attribute values, so I am providing my models as a ThingNode with filter_fields and interfaces = (relay.Node, ) rather than as a ThingType. Now, all examples I could find tell me to overload get_node() if I want to interact with the output, for instance in order to check for the user's permissions. However my implementation, as I have it working now, never gets past get_node(), but instead uses get_queryset(). I've looked into existing packages that offer permission management, such as django-graphene-permissions but this also hooks into get_node(). I am now unsure if I should just put my permission checks into ThingNode.get_queryset() instead, or is the fact that my code deviates from all the examples I find means that I'm setting this up the wrong way altogether. If anyone could give me some hints on this I'd be massively grateful! -

How to Filter by Status in Django Rest Framework with Square Brackets in Query Params
I'm encountering an issue with filtering a model by status in Django Rest Framework. Here's my current setup: When I filter using status=1,14, it works perfectly: class DepartmentFilter(filters.FilterSet): search = filters.CharFilter(method='filter_search') status = filters.CharFilter(method='filter_status') class Meta: model = Department fields = ['search', 'status'] def filter_search(self, queryset, name, value): print("filter_search", value) return queryset.filter(Q(token__icontains=value)) def filter_status(self, queryset, name, value): print("filter_status", value) # Verificar que el filtre s'executa if value: status_values = value.split(',') return queryset.filter(status__id__in=status_values) return queryset However, I'm having trouble capturing the query parameter when I use status[]=1,14. I've tried the following without success: status = filters.CharFilter(method='filter_status[]') status = filters.CharFilter(method='filter_status%5B%5D') There doesn't seem to be a way to create a function to capture this. Resolving status[] is a first step because ultimately, I want to work with the call filters[status][] = 1,14. I haven't found a way to handle this. Can anyone provide some guidance? Thank you! -

Issue with creating new pigeon and his parent records in a Django form
I am new to programming and currently learning Django. I am working on a web application where users can register new pigeons into a database. The registration form includes fields for the pigeon's name and a long dropdown menu with all the existing records for the father and the mother, which becomes quite tedious with many pigeons. Is there a strategy to solve this? Something like search fields to allow the user to search and select the father and the mother? And if parents do not exist, to add functionality to register them from there, similar to the admin form? If the father or mother doesn't exist in the database, the user should be able to create a new parent record directly from the main registration form without leaving the page. I have implemented the following model for the Pigeon: `python from django.db import models class Pigeon(models.Model): GENDER_CHOICES = ( ('male', 'Male'), ('female', 'Female'), ) name = models.CharField(max_length=100) gender = models.CharField(max_length=10, choices=GENDER_CHOICES) father = models.ForeignKey('self', on_delete=models.SET_NULL, null=True, blank=True, related_name='children_set') mother = models.ForeignKey('self', on_delete=models.SET_NULL, null=True, blank=True, related_name='children_set') def __str__(self): return self.name ` I'm facing an issue where I can't seem to create new parent records from the main registration form.

Resolving Celery Timeout Issues on Heroku: 504 Errors for Long-Running Asynchronous Tasks

Here are the attempts I made without success: Added --timeout 600 in the gunicorn command in the Procfile Added --time-limit=7200 in the celery command in the Procfile Added a timeout to the API request: requests.post(url, json=payload, headers=headers, timeout=600) Modified the configuration in celery.py app = Celery("mngrs_backend") app.conf.update( task_soft_time_limit=60 * 10, task_time_limit=60 * 12, ) Added in the project settings: CELERY_BROKER_TRANSPORT_OPTIONS = { "visibility_timeout": 60 * 60 * 2, # 2 hours } Locally with Celery, I do not have any timeout issues. I contacted Heroku support, but they told me the problem is with my Celery configuration. Does anyone have a solution? -
How to output the name of the current tag to the template? (The one we are in)
I'm trying to display the name of the current tag, i.e. the one we are in. Does not work. How to write correctly to display a tag in a template? #Models from django.db import models from taggit.managers import TaggableManager class Blog(models.Model): title = models.CharField(max_length=150) created_at = models.DateTimeField(auto_now_add=True) description = models.CharField(max_length=550) tags = TaggableManager() def __str__(self): return self.title #Views from django.shortcuts import render from django.views.generic import ListView from .models import * from taggit.models import Tag class TagMixin(object): def get_context_data(self, **kwargs): context = super(TagMixin, self).get_context_data(**kwargs) context['tags'] = Tag.objects.all() return context class PostIndexView(TagMixin,ListView): model = Blog template_name = 'blog.html' queryset=Blog.objects.all() context_object_name = 'posts' class TagIndexView(TagMixin,ListView): model = Blog template_name = 'blog.html' context_object_name = 'posts' def get_queryset(self): return Blog.objects.filter(tags__slug=self.kwargs.get('tag_slug')) #Templates {% if tag %} <h3>Posts by tag: {{ tag }}</h3> <!-- Does not display tag name --> {% endif %} P.s. The site asks for more description, but what else can be described here? The problem with the output is described -
Django Best practices: migration & contenarization
I am working on a Django API and I'd like to add a bit of CI/CD to it. It dockerize my app with FROM python:3.12 WORKDIR /app COPY requirements.txt . RUN pip install --no-cache-dir -r requirements.txt COPY . . EXPOSE 8000 ENV DJANGO_SETTINGS_MODULE=vocab_dictionnary.settings CMD ["python3", "manage.py", "runserver", "0.0.0.0:8000"] I then add a docker-compose.yml services: db: image: postgres:14 volumes: - postgres_data:/var/lib/postgresql/data/ environment: - "POSTGRES_USER=" - "POSTGRES_PASSWORD=" - "POSTGRES_DB=" ports: - 5438:5432 healthcheck: test: pg_isready -U ${POSTGRES_USER:-postgres} -d ${POSTGRES_DB:-${POSTGRES_USER:-postgres}} interval: 5s timeout: 5s retries: 120 start_period: 30s web: build: . command: python3 /code/manage.py runserver 0.0.0.0:8000 volumes: - .:/code ports: - 8000:8000 depends_on: db: condition: service_healthy environment: - "POSTGRES_HOST_AUTH_METHOD=trust" volumes: postgres_data: The end of my main.yml file for github actions looks like this - name: Run Database Migrations uses: appleboy/ssh-action@master with: host: ${{ secrets.SERVER_HOST }} username: ${{ secrets.SERVER_USERNAME }} password: ${{ secrets.SERVER_PASSWORD }} script: | cd /${{ secrets.SERVER_USERNAME }}/api/vocab_dictionnary/ docker compose exec web python manage.py migrate Finally, to simplify my local dev workflow, I added this in a Makefile: restart: docker compose down docker compose build docker compose up -d docker compose run web python3 manage.py makemigrations docker compose run web python3 manage.py migrate My first problem is that my migrations doen't apply …
