How to sort fields?

Question

Django

I need to sort notes by creation date, by category, and so on. tell me how to do it right?
a method that simply displays all the notes looks like this

def index(request):    
    note = Note.objects.filter(user=request.user.id)        
    return render(request, 'note/index.html',
                    {                    
                    'note' : note,                       
                    }					
                    )

what should I do now? which is easier to implement? can create buttons for each sorting, but how then to process everything in views?

Answer 1

Well, probably it would be necessary to add a date, a category to the model, and then read the Dzhanga doc and see how to do sorting in it.

Answer 2

Try Django-filter
Generic, reusable application to alleviate writing some of the more mundane bits of view code. Specifically, it allows users to filter down a queryset based on a model's fields, displaying the form to let them do this.

Answer 3

It is possible to implement requests through GET, and in view through if / elif filtering or sorting branching:

def index(request):
    if request.GET['pub_date']:
        items = Note.objects.order_by('-pub_date')
    else:
        items = Note.objects.all()
return render(...)

You can do whatever checks you like.
Or, instead of pub_date, use a generalized variable, from which it will take a condition for filtering / sorting.

Answer 4

I do it through filters, for example Publisher.objects.filter(name__contains="press")
Will return all objects named press. Instead of press, you insert the name of the variable that you pass from the template. Here, read djbook.ru/ch05s11.html
