A complete guide to Views, URLs, and Meta Title/Description/Keywords for the Django Community Application using Django REST Framework.

1. Views (community/views.py)

from rest_framework import generics, permissions
from django.shortcuts import get_object_or_404

from .models import (
    Community, CommunityPost, Comment, CommunityMembership
)
from .serializers import (
    CommunityListSerializer,
    CommunityDetailSerializer,
    CommunityPostListSerializer,
    CommunityPostDetailSerializer,
    CommunityPostCreateSerializer,
    CommentSerializer,
    CommentCreateSerializer,
    CommunityMembershipSerializer,
)

# ====================== Community Views ======================

class CommunityListCreateView(generics.ListCreateAPIView):
    """List all public communities or create a new one"""
    queryset = Community.objects.filter(is_public=True).select_related('created_by')
    serializer_class = CommunityListSerializer
    permission_classes = [permissions.IsAuthenticatedOrReadOnly]

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


class CommunityDetailView(generics.RetrieveUpdateDestroyAPIView):
    """Retrieve, update or delete a community"""
    queryset = Community.objects.select_related('created_by')
    serializer_class = CommunityDetailSerializer
    lookup_field = 'slug'
    permission_classes = [permissions.IsAuthenticatedOrReadOnly]


# ====================== Community Post Views ======================

class CommunityPostListCreateView(generics.ListCreateAPIView):
    """List posts in a community or create a new post"""
    serializer_class = CommunityPostListSerializer
    permission_classes = [permissions.IsAuthenticatedOrReadOnly]

    def get_queryset(self):
        community_slug = self.kwargs.get('community_slug')
        return CommunityPost.objects.filter(
            community__slug=community_slug
        ).select_related('author', 'community').prefetch_related('tags', 'likes')

    def perform_create(self, serializer):
        community = get_object_or_404(Community, slug=self.kwargs.get('community_slug'))
        serializer.save(author=self.request.user, community=community)

    def get_serializer_class(self):
        if self.request.method == 'POST':
            return CommunityPostCreateSerializer
        return CommunityPostListSerializer


class CommunityPostDetailView(generics.RetrieveUpdateDestroyAPIView):
    """Get, update or delete a specific post"""
    serializer_class = CommunityPostDetailSerializer
    permission_classes = [permissions.IsAuthenticatedOrReadOnly]
    lookup_field = 'slug'

    def get_queryset(self):
        community_slug = self.kwargs.get('community_slug')
        return CommunityPost.objects.filter(
            community__slug=community_slug
        ).select_related('author', 'community').prefetch_related('tags', 'likes', 'comments')


# ====================== Comment Views ======================

class CommentListCreateView(generics.ListCreateAPIView):
    """List comments or add a new comment on a post"""
    serializer_class = CommentSerializer
    permission_classes = [permissions.IsAuthenticatedOrReadOnly]

    def get_queryset(self):
        post_slug = self.kwargs.get('post_slug')
        return Comment.objects.filter(
            post__slug=post_slug, parent=None
        ).select_related('user').prefetch_related('replies')

    def perform_create(self, serializer):
        post = get_object_or_404(CommunityPost, slug=self.kwargs.get('post_slug'))

# ====================== Membership Views ======================

class JoinCommunityView(generics.CreateAPIView):
    """Join a community"""
    serializer_class = CommunityMembershipSerializer
    permission_classes = [permissions.IsAuthenticated]

    def perform_create(self, serializer):
        community = get_object_or_404(Community, slug=self.kwargs.get('slug'))
        serializer.save(user=self.request.user, community=community)

2. URLs (community/urls.py)

from django.urls import path
from .views import (
    CommunityListCreateView,
    CommunityDetailView,
    CommunityPostListCreateView,
    CommunityPostDetailView,
    CommentListCreateView,
    JoinCommunityView,
)

app_name = 'community'

urlpatterns = [
    # Communities
    path('communities/', CommunityListCreateView.as_view(), name='community-list-create'),
    path('communities/<slug:slug>/', CommunityDetailView.as_view(), name='community-detail'),

    # Join Community
    path('communities/<slug:slug>/join/', JoinCommunityView.as_view(), name='join-community'),

    # Posts
    path('communities/<slug:community_slug>/posts/', 
         CommunityPostListCreateView.as_view(), name='post-list-create'),
    
    path('communities/<slug:community_slug>/posts/<slug:slug>/', 
         CommunityPostDetailView.as_view(), name='post-detail'),

    # Comments
    path('communities/<slug:community_slug>/posts/<slug:post_slug>/comments/', 
         CommentListCreateView.as_view(), name='comment-list-create'),
]

3. SEO Meta Title, Description & Keywords

Updated save() Methods in Models

Community Model

def save(self, *args, **kwargs):
    if not self.slug:
        base_slug = slugify(self.name)[:150]
        self.slug = f"{base_slug}-{uuid4().hex[:8]}"

    # SEO Auto Generation
    if not self.meta_title:
        self.meta_title = f"{self.name} Community | Discussions & Resources"

    if not self.meta_description:
        if self.description:
            self.meta_description = self.description[:157] + ("..." if len(self.description) > 160 else "")
        else:
            self.meta_description = f"Join {self.name} - A vibrant community to discuss, share knowledge and connect with like-minded people."

    if not self.meta_keywords:
        keywords = slugify(self.name).replace('-', ', ')
        self.meta_keywords = f"{keywords}, community, forum, discussion, members"

    super().save(*args, **kwargs)

CommunityPost Model

def save(self, *args, **kwargs):
    if not self.slug:
        base_slug = slugify(self.title)[:150]
        self.slug = f"{base_slug}-{uuid4().hex[:6]}"

    # SEO Auto Generation
    if not self.meta_title:
        self.meta_title = f"{self.title} | {self.community.name}"

    if not self.meta_description:
        if self.content:
            desc = self.content[:157].strip()
            self.meta_description = desc + ("..." if len(self.content) > 160 else "")
        else:
            self.meta_description = f"Read this interesting post in the {self.community.name} community."

    super().save(*args, **kwargs)

Updated Serializers (Include Meta Fields)

# In CommunityDetailSerializer
fields = [
    'id', 'name', 'slug', 'description', 'is_public',
    'meta_title', 'meta_description', 'meta_keywords',   # SEO Fields
    'member_count', 'created_by', 'created_at'
]

# In CommunityPostDetailSerializer
fields = [
    'id', 'title', 'slug', 'content',
    'meta_title', 'meta_description',                    # SEO Fields
    'community', 'author', 'tags',
    'like_count', 'comment_count', 'is_liked', 'created_at'
]

---

Recommended Meta Lengths

Field	Recommended Length	Purpose
meta_title	50–60 characters	Page title in search results
meta_description	150–160 characters	Description in search results
meta_keywords	5–10 comma-separated	Helps search engines
