在 Django 中创建一个简单的多用户应用程序

Question

So I've got three users, a teacher , student , and admin . Both teacher and student users work fine but when I try to login using the admin form, it redirects to the student login form. I think it's because there's something wrong with the urls.py and the way the next parameter is configured but I'm not quite sure where to proceed.

Any help is much appreciated. Let me know if you need more information

Here are my admin views.py

@login_required
@admin_required
def profile(request):
    if request.method == 'POST':
        u_form = UserUpdateForm(request.POST, instance=request.user)
        p_form = ProfileUpdateForm(request.POST,
                                   request.FILES,
                                   instance=request.user.profile)
        if u_form.is_valid() and p_form.is_valid():
            u_form.save()
            p_form.save()
            messages.success(request, f'Your account has been updated!')
            return redirect('profile')

    else:
        u_form = UserUpdateForm(instance=request.user)
        p_form = ProfileUpdateForm(instance=request.user.profile)

    context = {
        'u_form': u_form,
        'p_form': p_form
    }

    return render(request, 'users/profile.html', context)

main urls.py

urlpatterns = [

Try just removing @login_required from your profile view.

Since Django decorators work top-down, @login_required will kick in before @admin_required . But from https://pypi.org/project/django-simple-rest/ :

admin_required simply makes sure that the user is logged in and is also a super user before they will be granted access to the decorated view method.

So, I think that @admin_required will already check if the user is logged in.
