Question

Django

There is an extended User model, there is a form that is associated with this model. How to implement a function for editing data?

def show_user_form(request):
    if request.method == 'POST':
        form = RedactInfoUserForm(request.POST, request.FILES)
        if form.is_valid():
            form.save()
            redirect('profile')
    else:
        form = RedactInfoUserForm()
    return render(request, 'shop/user_profile.html', {'form':form})

Answer 1

Add a parameter to the form (in both calls):

form = RedactInfoUserForm(instance=some_user) # some_user - КОНКРЕТНЫЙ юзер из бд, выбранный по id/логину и т.д.
