在Django 3中实现Post和Category模型的视图和URL模式,可以按照以下步骤进行:
下面是一个示例:
$ django-admin startproject myproject
$ cd myproject
$ python manage.py startapp myapp
from django.db import models
class Category(models.Model):
name = models.CharField(max_length=100)
def __str__(self):
return self.name
class Post(models.Model):
title = models.CharField(max_length=100)
content = models.TextField()
category = models.ForeignKey(Category, on_delete=models.CASCADE)
def __str__(self):
return self.title
from django.shortcuts import render
from django.views.generic import ListView, DetailView
from myapp.models import Post, Category
class PostListView(ListView):
model = Post
template_name = 'post_list.html'
context_object_name = 'posts'
class PostDetailView(DetailView):
model = Post
template_name = 'post_detail.html'
context_object_name = 'post'
class CategoryListView(ListView):
model = Category
template_name = 'category_list.html'
context_object_name = 'categories'
class CategoryDetailView(DetailView):
model = Category
template_name = 'category_detail.html'
context_object_name = 'category'
from django.urls import path
from myapp.views import PostListView, PostDetailView, CategoryListView, CategoryDetailView
urlpatterns = [
path('posts/', PostListView.as_view(), name='post_list'),
path('posts/<int:pk>/', PostDetailView.as_view(), name='post_detail'),
path('categories/', CategoryListView.as_view(), name='category_list'),
path('categories/<int:pk>/', CategoryDetailView.as_view(), name='category_detail'),
]
from django.contrib import admin
from django.urls import include, path
urlpatterns = [
path('admin/', admin.site.urls),
path('', include('myapp.urls')),
]
现在,你可以通过访问相应的URL路径来查看和操作Post和Category模型的数据。例如,访问/posts/
将显示所有的Post列表,访问/posts/1/
将显示ID为1的Post的详细信息。
这是一个简单的示例,你可以根据实际需求进行更复杂的开发和定制。对于更多关于Django的信息和教程,你可以参考腾讯云的Django产品介绍。
