Hi, I was following up on your tutorial Django + AngularJS for a Powerful Web Application where I get to edit /src/blog/urls.py I tried to import from django.views.genric.base import TemplateView. When I cd 'd to src folder and run python manage.py runserver I got the following error:
ImportError: No module named genric.base

First of all, appreciate this project. This is very helpful. As I know tags feature is essential for a blog system. Admin should be able to control (add/edit/delete) tags and client user should be able to filter blogs via tags or searching.

models.py in posts app.

replace the exiting upload_location function with this code snippet. I have already ported my db to Postgres, hence I ain't making a pull request.

def upload_location(instance, filename):
     #filebase, extension = filename.split(".")
     #return "%s/%s.%s" %(instance.id, instance.id, extension)
     PostModel = instance.__class__
     last = PostModel.objects.order_by("id").last()
     new_id = 1 if last == None else (last.id+1)

    """
    instance.__class__ gets the model Post. We must use this method because the model is defined below.
    Then create a queryset ordered by the "id"s of each object, 
    Then we get the last object in the queryset with `.last()`
    Which will give us the most recently created Model instance
    We add 1 to it, so we get what should be the same id as the the post we are creating.
    """
    return "%s/%s" %(new_id, filename)

I see no relationship between the post and comment am i missing something here ?

We don't need to declare the field names of SerializerMethodField instances in read_only_fields

Hi, i am an audience from Youtube.When i was learning this course, i found some questions.

• Blog-API-with-Django-Rest-Framework/src/accounts/api/views.py function:post
  I think it's needed check_password here.
• How can i sign out if it's needed.
  So i think the login function is not complete.Is it necessary to update self.request.user.So the user logged in can log out.

Thanks for the courses, i learned a lot from it.
Waiting for your replay.

When creating a post and there's no user logged in, the result shows "Authentication credentials were not provided", something like that.
When I'm trying to create a post and there's no user logged in, it doesn't show the message above. It still proceed in creating.

What do I need to do?

This the code the I used.

from rest_framework.generics import (
CreateAPIView,
DestroyAPIView,
ListAPIView,
UpdateAPIView,
RetrieveAPIView,
RetrieveUpdateAPIView
)

from rest_framework.permissions import (
AllowAny,
IsAuthenticated,
IsAdminUser,
IsAuthenticatedOrReadOnly,

)

from posts.models import Post

from .permissions import IsOwnerOrReadOnly

from .serializers import (
PostCreateUpdateSerializer,
PostDetailSerializer,
PostListSerializer
)

class PostCreateAPIView(CreateAPIView):
queryset = Post.objects.all()
serializer_class = PostCreateUpdateSerializer
permission_classes = [IsAuthenticated]

def perform_create(self, serializer):
    serializer.save(user=self.request.user)

class PostDetailAPIView(RetrieveAPIView):
queryset = Post.objects.all()
serializer_class = PostDetailSerializer
lookup_field = 'slug'
#lookup_url_kwarg = "abc"

class PostUpdateAPIView(RetrieveUpdateAPIView):
queryset = Post.objects.all()
serializer_class = PostCreateUpdateSerializer
lookup_field = 'slug'
permission_classes = [IsAuthenticatedOrReadOnly, IsOwnerOrReadOnly]
#lookup_url_kwarg = "abc"
def perform_update(self, serializer):
serializer.save(user=self.request.user)
#email send_email

class PostDeleteAPIView(DestroyAPIView):
queryset = Post.objects.all()
serializer_class = PostDetailSerializer
lookup_field = 'slug'
#lookup_url_kwarg = "abc"

class PostListAPIView(ListAPIView):
queryset = Post.objects.all()
serializer_class = PostListSerializer
