Angular – Got warning after update angular 7 to angular 8 version

• The CLI offers a command line flag to change your style when creating a new project with ng new my-app --style=scss

• As you can see, the extension is .scss, not .sass (at least for the syntax you're using, which is LESS)

• You are missing a semicolon h1 { color: red; }

• Remember to update your angular.json and component files accordingly if you don't reecreate a new project to resolve that

@list_route and @detail_route are extra actions that we can add to a ViewSet. Both provide a custom routing facility in view set. Any methods on the ViewSet decorated with @detail_route or @list_route will also be routed. list_route will give all the related records, whereas detail_route will provide only a particular record. For example, given a method like this on the UserViewSet class:

class UserViewSet(ModelViewSet):
    ...

    @detail_route(methods=['post'], permission_classes=[IsAdminOrIsSelf])
    def set_password(self, request, pk=None):

The following URL pattern would additionally be generated:

URL pattern: ^users/{pk}/set_password/$ Name: 'user-set-password'

def myview(request , id):
