文章管理系统

文章管理系统是一个用于管理文章的后台系统，包括文章的增删改查。

#### **3.1 模型设计**

文章模型已经在博客系统中定义，这里不再重复。

#### **3.2 Django Admin集成**

通过Django Admin管理文章。

**示例：自定义Admin界面**

Python复制

```python
from django.contrib import admin
from .models import Post

class PostAdmin(admin.ModelAdmin):
    list_display = ('title', 'author', 'created_at')
    search_fields = ('title', 'content')
    list_filter = ('author', 'created_at')

admin.site.register(Post, PostAdmin)
```

#### **3.3 API开发**

使用Django REST framework为文章管理系统开发API。

**示例：文章序列化器**

Python复制

```python
from rest_framework import serializers
from .models import Post

class PostSerializer(serializers.ModelSerializer):
    class Meta:
        model = Post
        fields = ['id', 'title', 'content', 'author', 'created_at', 'updated_at']
```

**示例：文章视图集**

Python复制

```python
from rest_framework import viewsets
from .models import Post
from .serializers import PostSerializer

class PostViewSet(viewsets.ModelViewSet):
    queryset = Post.objects.all()
    serializer_class = PostSerializer
```

**示例：API路由**

Python复制

```python
from django.urls import path, include
from rest_framework.routers import DefaultRouter
from .views import PostViewSet

router = DefaultRouter()
router.register(r'posts', PostViewSet)

urlpatterns = [
    path('', include(router.urls)),
]
```
