By Convention, when creating an application in django is it more common to access the backend directly or use API's to make the CRUD?
I'm a beginner and now that I've done all the views and html, I'm in a connection phase with the backend, I would like to know what is most used, to do it correctly. PS: this will have a large number of users -
Inline CSS not following @media min-width and max-width properties
I am creating a pricing page in my Django app which has 3 columns. If the screen size is more than 768 pixels, I want it to show all 3 columns side-by-side. But if it's less 768 pixels, I want there to only be 1 column with the different pricing options on top of each other. For some reason, the @media properties are not being followed. It doesn't matter what the screen size is, the page is always showing 3 columns. The below screenshot should only have 1 column (like most mobile-friendly pages) Current page: Js Fiddle - LINK The strange thing is that in this JS Fiddle, it does seem to be following the @media screen and (max-width) properties.

can't refresh the data in a DIV python Django nor the page after a jquery
Let me start by saying I have 2 variables in an HTML template(messages and users) and I have multiple buttons that when one of them is clicked it calls a jquery code that sends a post request to a Django server and it returns an update to a variable(messages) however, it's not updating the loop, I also tried to return a new HTML page that contains the new variable updated but the jquery is not updating the whole page with the new HTML if I can update the variable alone it would be better and if I can't do that how can I make jquery use the new HTML page the python code i used to return the update to the varialbe messages: if request.method == 'POST': send=Message.objects.filter(from_id=request.POST.get('userId'),to_id=2) rec=Message.objects.filter(from_id=2,to_id=request.POST.get('userId')) messages=sorted(chain(rec, send),key=lambda instance: instance.id,reverse=True) print(messages) return HttpResponse(list(messages)) and the code i used to return new HTML template: m = Message.objects.filter(to_id=2).order_by('-id') users = {} for i in m: if users.get(i.from_id.username) == None: users[i.from_id.username] = User.objects.get(id=i.from_id.id) users = list(users.values()) send=Message.objects.filter(from_id=users[0].id,to_id=2) rec=Message.objects.filter(from_id=2,to_id=users[0].id) messages=sorted(chain(rec, send),key=lambda instance: instance.id,reverse=True) if request.method == 'POST': send=Message.objects.filter(from_id=request.POST.get('userId'),to_id=2) rec=Message.objects.filter(from_id=2,to_id=request.POST.get('userId')) messages=sorted(chain(rec, send),key=lambda instance: instance.id,reverse=True) print(messages) return render(request,'psych.html',{"users":users, "messages":list(messages)}) return render(request,'psych.html',{"users":users, "messages":list(messages)}) the HTML code and jquery code that uses the variable and … -
password reset emails are coming to the host email
I'm making an e-commerce but it sends the password confirmation email to the host.

Compare existing Django model's instances for matching fields?
I am working on a fairly difficult django query. The query needs to check against all of the Student model instances, and check if any 2 instances have 2+ matching database fields. I have this so far which works if I throw in a hard-coded search term or the value is grabbed from a form input value. Student.objects.annotate( match_count=Case(When(full_name='hardcodedvalue', then=1), default=0, output_field=IntegerField())).annotate( match_count=F('match_count') + Case(When(phone_number='hardcodedvalue', then=1), default=0, output_field=IntegerField())).annotate( match_count=F('match_count') + Case(When(student_email='hardcodedvalue', then=1), default=0, output_field=IntegerField()) ).filter(match_count__gt=1) This works great when compared to hardcoded value which is really a form input. If any 2 fields come back as a match, then it returns the correct result. Now I am struggling to run the query in a similar way, to query against items already existing in the database. I need to run a check that instead of checking against a form input, it checks all of the Student models fields. For example full name would have to check against... full_name=Student.objects.all().value('full_name') -

Is there a way to enable django DEBUG mode using nginx?
I deployed my project on served with nginx and gunicorn. When I am trying to access a particular endpoint there is an error: "500 Internal Server Error", that is bad, so I have decided to enable django debug mode, but nothing has changed.
