Creating user specific form access permissions / validation in django admin
I'm using a 'Task' Model to create operations/administrative tasks in my dashboard. Each task has an assignee, and a reviewer. The assignee completes the task by passing several checks, and the reviewer verifies their work, both of these require each user to edit a check, but neither user should be able to access or modify the other's result. If the assignee views the Task (with checks inline), they should only be able to modify the "result" and "comment" elements of the check, where as the reviewer can only edit the "review_result" and "reviewer_comment" elements. To validate this I need to use the fact that given a check, the current user editing the page is equal to check.task.assignee or check.task.reviewer. I cannot find a simple way to do this, even using django-guardian, as this requires field-level permissions, rather than object level. I considered using modelForm validation, but cannot find a way to access the user from within the model with some hacks such as django-cuser. Is there another architecture which would allow this? The only way forward that I can see is to use django-guardian combined with two checks, a check and a checkReview, and set object level permissions as the … -

Importing model in utils.py causes ImproperlyConfigured
I have created a file called utils.py in my Django app, where I keep random classes or functions that do something. I have run into an issue, where I can't import any model in utils.py file. I have models called User which inherit from AbstractUser and it's been said to Django by: AUTH_USER_MODEL = 'main.User' I have also a model called Project. Whenever I type from main.models import Project or User in utils.py I get django.core.exceptions.ImproperlyConfigured: AUTH_USER_MODEL refers to model 'main.User' that has not been installed Of course main is in installed apps in settings. I have solved this before by using get_user_model() for User, but there is no such a function to get a Project. -

How to have get_or_create() save an object, even if object.attribute passed in doesn't exist
I have a function: podcast_instance = Show.objects.get_or_create(title=parsed_podcast.title day_published=parsed_podcast.title ) It's getting the data from an object (parsed_podcast) being passed in. It has a large number of attributes, depending on the podcast, some are there and some are not. I have a lot of datasources being passed into the 'Podcast' object, so I'd like for my function to save what is available, and if there is nothing available, or 'parsed_podcast object has no attribute x' then to just save 'nothing' into that attribute and carry on. The model Show allows for these attributes to have no value. However, get_or_create just throws an AttributeError and stops, and if I put it in a Try block and print the error this way: try: podcast_instance = Show.objects.get_or_create(title=parsed_podcast.title) except AttributeError: Exception It still does not save the data. How can I create an object and just save what is available? -
