Is it possible to add a user-filtered button in Django
I have a Base.html template that extends to the rest of my HTML pages in my app, In this base.html file, it has a nav-bar that has a bunch of < a > tags that link to the different pages. Is it possible to limit the visibility of this < a > tag based on a user's name or users role on the database or would I need to add this in the function of rendering the page to which the < a > tag loads? -

ImportError: cannot import name 'Affiliate' from partially initialized module 'affiliate.models' (most likely due to a circular import)
I'm getting a circular import error in django and can't seem to solve it. here's my models.py in affiliate(app) from member.models import Member class SubAffiliate(models.Model): member_id = models.ForeignKey(Member, on_delete=models.CASCADE) and here's my models.py in member(app) from affiliate.models import Affiliate class Member(models.Model): affiliates = models.ManyToManyField(Affiliate, blank=True, related_name="members_affiliate") for solving the problem I tried importing like this import affiliate.models and there use it like this affiliate.models.Affiliate then I get this error AttributeError: module 'affiliate' has no attribute 'models' what should I do to resolve this error.

"TypeError: cannot unpack non-iterable AsyncResult object" while using Django?
I'm using Django with Celery to make an async call that returns multiple values. However, when trying to unpack these variables in my Django view, it throws up the TypeError mentioned above. Here's what I have so far: Relevant Code views.py def render_data(request): reddit_url = request.POST.get('reddit_url') sort = request.POST.get('sort') var1, var2 = celery_run.delay(reddit_url, sort) data = { 'var1': var1, 'var2': var2, } return JsonResponse(data) tasks.py @shared_task def celery_run(reddit_url, sort): var1, var2 = run_data(reddit_url, sort) return var1, var2 Expected Result vs Actual Ideally, the function would properly unpack and each variable would be assigned to the proper value from the function. Instead, I receive a typeerror indicating that I can't unpack async objects. I'm not entirely sure, but is that because I'm trying to unpack from a function thats still running? What I've tried Unpacking variables within tasks.py instead in views.py, did absolutely nothing but I prayed Followed the solution from TypeError: cannot unpack non-iterable NoneType object but unfortunately extra indents makes my code work less If I could get any info on what causes this error and the best method to approach this, I'd be grateful. Thanks! -
Use Verbatim tag inside a django simple tag
I wrote a simple tag that gets one argument and returns True or False. @register.simple_tag def iswatched(movieDB_id): try: movie = TitleMovie.objects.get(movieDB_id=movieDB_id) return movie.watched except: return False I use a javaScript library called Handlebars which has syntax exactly like Django template tag. So I use {%verbatim%} tag to not render those parts. but I need to get the value with Handlebars tag like this ( {{value}} ) and pass it to simple tag {%iswatched {{value}} as watched%}. but it gets an error because it render {{value}} as Django template tag. I tried this but it didn't work. {%iswatched ({%verbatim%}{{id}}{%endverbatim%}) as watched%} how should i have it not render {{value}} inside iswatched simple tag -

How to have dynamic data on webpage using Django models?
I have a requirement where the dropdown menu using Django models in my webpage needs to have live/dynamic data from a third party server. For eg. current models data is emp1,emp2 but if the third party server adds emp3, then I should be able to display emp1,emp2,emp3 in my webpage when a user refreshes the webpage. How can I achieve that using django models? (I know we can do this without Django models by making an ajax call directly from the webpage, but I can't do so because of security restriction so I have to fetch this data in the backend, and with Django models currently I am only able to get the data in my database once when the server is started and NOT when the third party server updates its database). -

How to allow only React to make an API request in my Django-React Project?
I was making a tutorial integrating Django and React to make a full-stack project, and in a part of it they configured in settings.py to allow anyone to make an api request,but it's too dangerous to allow it,everybody could wipeout my whole database or make something else with my application,and then I came with the idea to restrict to only React to do it -
