Django: how to run function after changing m2m model
I have a m2m relation between two models Plot and Station. The m2m field is declared inside the Station model. When a user create/update a station or a plot, I want to run a 'download' function to create some config files (which will be used from another program) using data from the database. I added this function in the save and delete methods. But it did not work when the m2m field is changed. It seems the 'download' function is called before the m2m field is saved. I have found that adding a receiver to check m2m_changed on Station model, solves this problem (even if it means running the function twice). My issue now is that when a user delete a plot, the station will be updated in the database as expected, but I can not figure out how to run the 'download' function on the station after this has been done. stations/models.py class Station(models.Model): name = CICharField( max_length=50, unique=True, error_messages={ "unique": _("That name already exists."), }, ) ... # list of plots available for the station plots = models.ManyToManyField( Plot, blank=True, related_name="stations", ) ... def save(self, *args, **kwargs): """ """ super().save(*args, **kwargs) from .util import download_station download_station() def delete(self, … -

How to implement an Asynchronus function in synchrounous function
I'm creating an app, and I want my synchronous Django view function to execute an asynchronous function that saves a large number of database items.

How can I enforce inheritance in my Django models? [closed]
In my Django app, I have an abstract model called MyModel that has e.g. created_at and updated_at fields. I want all the models in my project to subclass MyModel rather than using django.db.models.Model directly. We have several developers on our app, so I want to use some sort of linter or CI check to enforce that this happens. Is there a flake8 plugin, or something similar, I can use to enforce this inheritance? -

Extend django-invitations + django-allauth account adapter

Django template system to generate runnable programs
I'm considering using Django template system for a pretty peculiar use case and I'm looking for some guidance. I have an app which allows users to solve programming problems by submitting a code solution. The app allows users to write programs in several languages, including Python, JS/TS, and C. Each problem is associated with a suite of test cases meant to verify the correctness of the submitted solution. My app combines the user code and the test cases' code into a program that is run by a sandboxed environment. Right now, the way the submitted code and the test cases are combined is hard-coded and looks roughly like this: def get_testcase_execution_block( testcase: ExerciseTestCase, execution_results_list_identifier: str ) -> str: results_dict = get_random_identifier() exception_identifier = get_random_identifier() return ( f"try:\n" + f" {testcase.code}\n" + f" {results_dict} = {{'passed': True, 'id': {testcase.pk}}}\n" + f"except Exception as {exception_identifier}:\n" + f" ex_type, ex_value, ex_traceback = sys.exc_info()\n" + f" trace_back = traceback.extract_tb(ex_traceback)\n" + f" stack_trace = list()\n" + f" for trace in trace_back:\n" + f' stack_trace.append("File : %s , Line : %d, Func.Name : %s, Message : %s" % (trace[0], trace[1], trace[2], trace[3]))\n' + f" {results_dict} = {{'passed': False, 'id': {testcase.pk}, 'error': ex_type.__name__ + ': ' + … -

Non ORM Backend in Django
I'm working with a database that I can't alter, it doesn't have PK or FK which makes it difficult to interact with it using ORM Backend in Django. So I want to know if non ORM Backend in Django offers the same flexibility?
