Iterate Django Forms API fields
I have a Question model with some questions that I want to render on a page, together with input fields. So, the user has to type an answer to that question and then a view checks if it's true or false. I know I can manually render the form as HTML, but I thought using Django Forms API was faster. My idea is something like this: from django import forms from .models import Question class QuizForm(forms.Form): questions = Question.objects.all() for question in questions: question_field[] = forms.CharField(label=question.text, max_length=150) And then to call the form from a view, that passes it to the HTML template. That question_field list elements should be the Django form fields. I know it does not make any sense written like this (list elements cannot make a field), but this is just the best way to explain to you what I want to accomplish: creating Django Forms API fields in for loop. Hope you've understood. -

OpenEDX: Custom Fields in Registration Form
I have installed the OpenEDX fullstack VM dogwood release on my local server and I need to create custom fields in the registration page. I followed the instructions here.

I entered the following commands sudo su edxapp -s /bin/bash cd ~ source edxapp_env python /edx/app/edxapp/edx-platform/manage.py lms syncdb --settings=aws I get the following error message -

Git- understanding the output of a diff command
I recently took over the development of a Python/ Django project, where Git is used as the version control for software maintenance and releases etc. Having not used Git much at all before, I am still getting used to how to use it to manage version control effectively. I recently pushed some changes to the server to fix a particular bug- this bug has now been fixed, and the feature is working correctly on the live version of the software. However, when merging the branch on which I had been developing with the master branch, I needed to reset to an old version of the code as I managed to break my local master branch. Now, having pushed my local master to the server, with the fix for this bug implemented, it seems that I have broken another page on the server- there were some issues with this page a month or so ago, which I fixed at the time, and the reset that I performed on my local master was to a version that was last modified a few days ago, so this bug should not have been in the version that I reset to, but somehow this seems … -

Python code in Django not recompiling in daemon mode with Apache/mod_wsgi
I am running a Django application using Apache2 with mod_wsgi in daemon mode: WSGIDaemonProcess my_app_process WSGIScriptAlias /my_app /var/www/my_app/wsgi.py process-group=my_app_process WSGIScriptReloading On Whenever I make changes to my Python code on server (I know this is highly discouraged, but I'm only using it for debugging) I keep having trouble with recompiling the code, but only in subdirectories. Python files in the root directory of the application (i.e. settings.py) get recompiled nicely, but not the ones located in subdirectories (i.e. views.py of some app). The application directory is owned by the www-data user and the user has sufficient privileges (tested with 777). Restarting the Apache or touching the wsgi file only results in recompiling of the Python files in root directory of the application. -

What is the correct way of doing Django imports ?
I would like to understand if the there is a correct and accepted way of handling imports in Django?

Troubleshooting API timeout from Django+Celery in Docker Container
I have a micro-services architecture of let say 9 services, each one running in its own container. The services use a mix of technologies, but mainly Django, Celery (with a Redis Queue), a shared PostgreSQL database (in its own container), and some more specific services/libraries. The micro-services talk to each other through REST API. The problem is that, sometimes in a random way, some containers API doesn't respond anymore and get stuck. When I issue a curl request on their interface I get a timeout. At that moment, all the other containers answer well. There is two stucking containers. What I noticed is that both of the blocking containers use: Django django-rest-framework Celery django-celery An embedded Redis as a Celery broker An access to a PostgreSQL DB that stands in another container I can't figure out how to troubleshoot the problem since no relevant information is visible in the Services or Docker logs. The problem is that these API's are stuck only at random moments. To make it work again, I need to stop the blocking container, and start it again. I was wondering if it could be a python GIL problem, but I don't know how to check this … -
Is there a way to specify the database alias that is concerned by a RunPython operation in a Django migration?
I have a Django project that uses two databases. I defined a Database Router and everything works fine when running migrations, except for RunPython migration operations : in this case I have to "manually" check in the RunPython code function on which database alias the code is run to decide whether or not to apply the given operations. So far I have implemented a decorator that I use on every RunPython code function that checks whether or not to run the operation based on the current database alias. It works fine, but I was wondering if Django already provided a way to specify the database alias(es) concerned by a RunPython migration without having custom code. Is there such a way ? For information, here is the decorator : def run_for_db_aliases(database_aliases): def decorator(migration_function): def decorated(apps, schema_editor): if schema_editor.connection.alias not in database_aliases: return return migration_function(apps, schema_editor) return decorated return decorator This allows me to define code for RunPython migrations like this : @run_for_db_aliases(['default']) def forwards_func(apps, schema_editor): # Perform data operations on models that are stored in the 'default' database ... Is there a cleaner way to do this, like an option when instantiating a RunPython operation ? -
Django: Concurrent access to settings.py

Env variable in Vagrant provision with Ansible and Django
I am using Django and trying to configure Vagrant. In my settings file, I access an environment variable like so: CERTIFICATE = get_env_setting('CERTIFICATE_FILEPATH') get_env_setting() function looks like this: def get_env_setting(setting): try: return os.environ[setting] except KeyError: error_msg = "Set the %s env variable" % setting raise ImproperlyConfigured(error_msg) And at the end of provisioning I run migrations with ansible like this: - name: run migrations shell: > executable=/bin/bash {{ venv_dir }}/bin/python {{ project_dir }}manage.py migrate This is where I get this exception: ImproperlyConfigured: Set the CERTIFICATE_FILEPATH env variable I tried to add this env variable like this: - name: add env variables lineinfile: dest={{ home_dir }}.profile line="export CERTIFICATE_FILEPATH='/path/'" regexp="^export CERTIFICATE_FILEPATH" It did add this env variable to ~/.profile but the error still occurred. How can I fix this? -
Django OneToOne Fields to user ProgrammingError
I tried to add a ManyToManyField to user using a OneToOneField relation first. Here is my code: ENTERPRISE_TYPE_CHOICES = ( ('a', "A"), ('b', "B"), ('c', "C"), ) class Enterprise(models.Model): et_type = models.CharField( max_length = 10, choices=ENTERPRISE_TYPE_CHOICES, default='a' ) name = models.TextField(max_length=100) number = models.TextField(max_length=7) def __str__(self): return "%s %s %s" % (self.et_type, self.name, self.number) class Secretaire(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) workshop = models.ManyToManyField(Enterprise) @receiver(post_save, sender=User) def create_user_secretaire(sender, instance, created, **kwargs): if created: Secretaire.objects.create(user=instance) @receiver(post_save, sender=User) def save_user_secretaire(sender, instance, **kwargs): instance.profile.save() Then in the python manage.py shell I try : from django.contrib.auth.models import User u = User.objects.create(username="a", email="a@a.fr", password="a") And it throw the error : ProgrammingError: relation "helpdesk_secretaire" does not exist LINE 1: INSERT INTO "helpdesk_secretaire" ("user_id") VALUES (11) RE... (The User is still created but no can't acces to user.secretaire, it throws the same error) Do you have any clue about why I get this error?
