Django 3.1.3版本的表单没有保存到模型中

Question

我正在学习本教程

我已经回去写了完全匹配的代码。我有另一个名为category_ad的表单，它与此表单完全相同。但就我而言，我不明白bookmark_add为什么不使用表单条目更新数据库。

型号.py

from django.db import models
from django.contrib.auth.models import User

class Category(models.Model):
title = models.CharField(max_length=255)
description = models.TextField(blank=True, null=True)
created_by = models.ForeignKey(User, related_name='categories', on_delete=models.CASCADE)
created_at = models.DateTimeField(auto_now_add=True)
class Meta:
verbose_name_plural = 'Categories'
def __str__(self):
return self.title

class Bookmark(models.Model):
category = models.ForeignKey(Category, related_name='bookmarks', on_delete=models.CASCADE)
title = models.CharField(max_length=255)
description = models.TextField(blank=True, null=True)
url = models.CharField(max_length=255, blank=True)
created_by = models.ForeignKey(User, related_name='bookmarks', on_delete=models.CASCADE)
created_at = models.DateTimeField(auto_now_add=True)
def __str__(self):
return self.title

View.py

from django.shortcuts import render, redirect
from django.contrib.auth.decorators import login_required
from .forms import BookmarkForm

@login_required
def bookmark_add(request, category_id):
if request.method == 'POST':
form = BookmarkForm(request.POST)
if form.is_valid():
bookmark = form.save(commit=False)
bookmark.created_by = request.user
bookmark.category_id = category_id
bookmark.save()
return redirect('category', category_id=category_id)
else:
form = BookmarkForm()
context = {
'form': form
}
return render(request, 'bookmark/bookmark_add.html', context)

Forms.py

from django.forms import ModelForm
from .models import Bookmark

class BookmarkForm(ModelForm):
class Meta:
model = Bookmark
fields = ['title', 'description', 'url']

Urls.py

path('', dashboard, name='dashboard'),
path('categories/', categories, name='categories'),
path('categories/add/', category_add, name='category_add'),
path('categories/<int:category_id>/', category, name='category'),
path('categories/<int:category_id>/add_bookmark', bookmark_add, name='bookmark_add')
]

bookmark_add.html

{% extends 'core/base.html' %}
{% block content %}
<div class="container">
<h1 class="title">Add link</h1>
<form method="post" action=".">
{% csrf_token %}
{{ form.as_p }}
<button type="submit" class="button is-primary">Submit</button>
</form>
</div>
{% endblock %}

解决了这个问题！

这是一个愚蠢的问题，也是我的疏忽。感谢youtube上的内容创建者。我只需要添加"/"到add_bookmark的url路径。

问题：path('categories/<int:category_id>/add_bookmark', bookmark_add, name='bookmark_add')

修复：path('categories/<int:category_id>/add_bookmark/', bookmark_add, name='bookmark_add')
