7.5. Views Decorators

@login_required
@cache_page
@csrf_exempt
@method_decorator
@permission_required
@require_http_methods
@require_POST - view only accepts the GET method
@require_GET - view only accepts the POST method
@require_safe - view only accepts the GET and HEAD methods

7.5.2. permission_required

from django.contrib.auth.decorators import permission_required


@permission_required('customer.add_choice')
def my_view(request):
    ...

If the raise_exception parameter is given, the decorator will raise PermissionDenied, prompting the 403 (HTTP Forbidden) view instead of redirecting to the login page.

If you want to use raise_exception but also give your users a chance to login first, you can add the login_required() decorator:

from django.contrib.auth.decorators import login_required, permission_required


@login_required
@permission_required('customer.add_choice', raise_exception=True)
def my_view(request):
    ...

7.5.3. user_passes_test

from django.contrib.auth.decorators import user_passes_test


def email_check(user):
    return user.email.endswith('@example.com')


@user_passes_test(email_check)
def my_view(request):
    ...

7.5.4. require_http_methods

from django.views.decorators.http import require_http_methods


@require_http_methods(['GET', 'POST'])
def my_view(request):
    # do something
    pass

7.5.5. require_GET

from django.views.decorators.http import require_http_methods


@require_GET
def my_view(request):
    # do something
    pass

7.5.6. require_POST

from django.views.decorators.http import require_http_methods


@require_POST
def my_view(request):
    # do something
    pass
