'{}' 与参数 '('',)' 的反向 NoReverseMatch。: ['(?P<id>[0-9]+)/\Z']

Question

NoReverseMatch 在 /Bookstore/book_detail/7/ 找不到带有参数“（”，）“的“edit_book”。尝试了 1 种模式：['Bookstore/edit_book/(?P[0-9]+)/\Z']

网址.py 路径('edit_book/int:id/', views.edit_book, name = 'edit_book'),

# delet book url
       path('delete_book/<int:id>', views.delete_book, name = 'delete_book')

视图.py def edit_book（请求，ID）： book = Book.objects.get(id =id) 形式 = EditBookForm（实例 = 书） 如果 request.method == 'POST': form = EditBookForm(request.POST, request.FILES, instance = book) 如果 form.is_valid(): 表格.保存() 返回重定向（'家'） 上下文={'形式'：形式} 返回渲染（请求，'update_book.html'，上下文）

删除书，以id为参数

def delete_book(request, id):
    # getting the book to be deleted
    book = Book.objects.get(id=id)
    # checking if the method is POST
    if request.method == 'POST':
        # delete the book
        book.delete()
        # return to home after a success delete
        return redirect('home')
    context = {'book': book}
    return render(request, 'delete_book.html', context)
