Django UpdateView 生成“GET”请求而不是“POST”

Question

我正在关注一本名为 Django for Beginners 的书，并创建了一个显示报纸文章的项目。部分功能是能够编辑这些文章。我已尽可能密切关注，但在点击“更新”按钮时仍然出现错误：

我的 urls.py

from django.urls import path
from .views import (ArticleListView,
 ArticleUpdateView, 
 ArticleDetailView,
 ArticleDeleteView)

urlpatterns = [
    path('<int:pk>/edit/', ArticleUpdateView.as_view(), name = 'article_edit'),
    path('<int:pk>/', ArticleDetailView.as_view(), name = 'article_detail'),
    path('<int:pk>/delete/', ArticleDeleteView.as_view(), name = 'article_delete'),
    path('', ArticleListView.as_view(), name = 'article_list'),
]

我的意见.py

from django.shortcuts import render
from django.views.generic import ListView, DetailView
from django.views.generic.edit import UpdateView, DeleteView
from django.urls import reverse_lazy
from .models import Article

# Create your views here.
class ArticleListView(ListView):
    model = Article
    template_name = 'article_list.html'

class ArticleDetailView(DetailView):
    model = Article
    template_name = 'article_detail.html'

class ArticleUpdateView(UpdateView):
    model = Article
    fields = ('title', 'body')
    template_name = 'article_edit.html'

class ArticleDeleteView(DeleteView):
    model = Article
    template_name = 'article_delete.html'
    success_url = reverse_lazy('article_list')

我的models.py：

from django.db import models
from django.conf import settings
from django.contrib.auth import get_user_model
from django.urls import reverse

# Create your models here.
class Article(models.Model):
    title = models.CharField(max_length=225)
    body = models.TextField()
    date = models.DateTimeField(auto_now_add=True)
    author = models.ForeignKey(
        get_user_model(),
        on_delete=models.CASCADE,
    )

    def __str__(self):
        return self.title

    def get_absolute_url(self):
        reverse('article_detail', args=[str(self.id)])

我的 HTML：

<!-- templates/article_edit.html -->    
{% extends 'base.html' %}
    
{% block content %}
<h1>Edit</h1>
<form action="" method="post">{% csrf_token %}
{{ form.as_p }}\
<button class="btn btn-info ml-2" type="submit">Update Article {{article.pk}}</button>
</form>
{% endblock content %}

点击编辑按钮后，根据这本书，应用程序应该将我转发到“article_detail”页面，但是这并没有发生。

我们将不胜感激。

谢谢 安迪

Answer 1

最后只是在models.py中的get_absolute_url函数中简单地省略了一个return语句。
