why am I getting network error for my Django website?
My django website was integrated with default SQLite DB. Yesterday, I tried migrating it to Postgres, however, due to some password issue, the migration failed. Then I tried to fall back to SQLite just by uncommenting the SQLite portion in settings.py. But it failed too. I guess I broke my Database. To fix the issue I used the below CLI command to delete everything in the SQLite: python manage.py migrate my-app-name zero Then I used makemigratons and then migrate. So, here everything seem to go smoothly. However, now I faced the connectivity issue with my website. Its not launching from web browser. I don't know if I have messed my entire environment itself. My website is hosted on AWS on Ubuntu server, it has gunicorn and nginx up and running. Initially I was receiving some below error: A communication error occurred: The Web Server may be down, too busy, or experiencing other problems preventing it from responding to requests I checked the journalctl logs, and I found something like below: nginx.service: Failed to read PID from file /run/nginx.pid: Invalid argument To try to fix the issue I followed the web link. But, it is not working. I am not sure … -

DJANGO - dynamic form fields creation using ajax
I'm new to django, and i'm having trouble adding form fields dynamically with a click of a button using ajax. This is what I tried so far using modelformset_factory. In my views.py I have a code like this which is called to add a new field of author from ajax: if request.is_ajax: AuthorFormset = modelformset_factory(Author, form=AuthorForm) author_form = AuthorFormset(request.POST) if author_form.is_valid: return JsonResponse({'data': str(author_form)}) basically, what I want to do with that code is return a new formset with an initial value of the POST request sent from ajax with one extra field. But this code only returns the fields from the POST request without the extra field. How can I make it do that? I appreciate any help, thanks in advance! -

Foreign Key in Model causing IntegrityError NOT NULL constraint failed:

How track track field type in change log of a database Row
I have been working on Django and I wanted to track the changes of a table and I am thinking of a table to keep track of the changes on a field-based tracking system like audit_field (table_name, id, field_name, field_value, status, datetime) with the status column ready to track if this change has been approved or not and is visible on the model. but I wanted to keep track of the field types too to use database validation against it.

Django Custom User Model Optional Field and Integer Field with Specific Format
fellow devs! I am writing a custom user model in Django but I can't figure out how can I make a user input middle name for those who have it or won't force it for those who don't.

Django projects with Postgres stopped working after brew install
I was trying to get Selenium to work, and so followed the suggestion here to brew install geckodriver in the relevant virtual environment (pipenv). After having done that, my other virtual environments stopped working.

How do I make a ForeignKey field use Multiple Dropdowns from the same list, and remove duplicates as they are selected, in Django?
I am trying to set up a Django project that will reference a list of users. In one of my models, I am using ForeignKey fields to point at the table of users. I have several slots setup, linked to the table of users, and I would like to be able to select a user from that table when adding data. But I would also like the users name to be removed from the rest of the dropdowns if they are selected in one of the dropdowns. For Example. I have 3 users in my table. John, Mark, Andy In the entry page, I would like to have 3 dropdown fields. Each of them linked to the users table. In the first field when I click it, all three users should pop up as options, John, Mark and Andy. After selecting John, the second field should only give me the option to select Mark or Andy. After selecting Mark for the second field, the third field should give the option to select Andy, or stay blank. My models.py is setup like this: class Users(models.Model): name = models.CharField(max_length=15) class Session(models.Model): Slot1 = models.ForeignKey(Users, on_delete=models.CASCADE, related_name='Slot1') Slot2 = models.ForeignKey(Users, on_delete=models.CASCADE, related_name='Slot2') Slot3 …
