How can I set up international telephone input widget on Django crispy forms or any form tbh?
I tried using Django-intl-tel-input but the widget didn't load and had 404 errors in my terminal as mentioned in this question so I tried using the intl-tel-input and load the CSS/js files locally but the same problem happened so how can I make this work? I use Django-phonenumber-field to save the numbers in my model but I don't use it in my forms. I tried The Django-phonenumber-field widget and I didn't like that it wasn't so user-friendly. so what's the best way to integrate a phone number widget with country flags to the app? -

How to select one element instead of all elements using 'clicked' in a Django for loop
In my Django project I am trying to create a feature so that when someone clicks the cog element on my folder, it adds a class to only the one folder element I have clicked. My issue is that when I click the cog, it apply's the class to all of the other folders, and not just the one I want. I understand why it is doing this, but not sure how to fix it. When I click the cog It applys the css to all elements and not just the one I clicked with the cog.

CSS attributes in HTML page show blank (style="") when they are not | NGINX + Django
All static files in the project are being loaded (how do I know this? Bootstrap, and Fontawesome, which I have locally, work fine), everything seems to be in order, but, for some reason, all the CSS attributes in the HTML pages are rendered blank when in the source code this is not the case. I haven't been able to find an answer online, and since I don't really know what files to include from my code or settings, I think a simple code sample of the problem should suffice. html source: <div style="width:100px;"></div> html live: <div style=""></div> I would give more information if I knew what would be useful. I don't know where the problem resides. I've never had this happen. -

How to disallow creation of object if related foreign key doesn't exists?
Here is the setup class A(Model): pass class B(Model): a = ForeignKey(A, on_delete=CASCADE) assert A.objects.all().count() == 0 try: B(a_id=1) except IntegrityError: print('error') # ... another logic to deal with situation DB is PostgreSQL. There are no A objects yet (at least with id=1). I try to create object B using the id of some hypothetical object A fetched from the 3rd party. Expectation If there is no object A -> IntegrityError is thrown -> deal with it (eg create object A with id=1 and rerun). Reality Object B is created anyway despite having a foreign key constraint, IntegrityError is thrown but is not fetched by try/except. Everything is messed up. I don't what to get_or_create object A beforehand because I will end up with 2 queries every time I want to create B (and I need to create it many times while most of the time needed object A is already in DB) -

How to control color theme using configurations in Django admin?
Basically I have Django project (using Docker) installed on many sites with different logos, content, etc. Problem seems to be that also theme colors should be configurable for each site. Optimal solution would be to have some color codes (primary, secondary, etc) configurable, which would eventually change CSS content. Project uses Bootstrap 4, which uses SASS (SCSS) that compiles as CSS, so now my GIT contains single SCSS file and compiled final CSS should be different on each site. All solutions I have figured out seem to be hacks, so I wonder is there any "clean solutions" for this? Solution don't have to be necessarily "real time", like configurations in Django Admin UI, but that would definitely be plus. Anyway, something that works even if I make changes to common code base and update that to all sites. -

Django WeasyPrint - Export filtered list
