Django:从html表单向模型插入值时找不到模型？

我正在尝试使用基本django表单向sqlite数据库插入值

这些是我的设置

型号.py

   def get_absolute_url(self):
        return reverse ('books:detail',kwargs={'pk':self.pk})

book\u form.html

{% extends 'books/base.html'%}
 {%block content%}


                   <form class="form-horizontal" action="" method="post" enctype="multipart/form-data">
                        {% csrf_token %}
                         {{form}}

                        <div class="form-group">
                                <button type="submit" class="btn btn-sucess">Submit
                                </button>
                            </div>
                      </form>
{% endblock %}

在我看来，url.py很好，因为我可以使用模型表单进行插入，它很好，但在这里它返回了错误

如何解决此问题并使用表单插入值？

您正在从模型调用Book。你应该打电话给Book，因为它已经导入了。 将代码更改为：

    if form.is_valid():
        book_obj=Book()
        book_obj.name = request.POST.get("name")
        book_obj.author = request.POST.get("author")
        book_obj.genere = request.POST.get("genere")
        book_obj.year = request.POST.get("year")
        book_obj.save()
        return redirect('books:index')

另一个错误

MultiValueDict'对象没有属性'\u committed'

删除这一行

book\u obj.image=request.FILES

并重试现在的事情是，在将其直接分配给图像之前，您需要处理

request.FILES

，这是一个不同的问题，您应该首先研究如何使用德扬戈。官方文档中有一个简单的例子，你几乎可以复制粘贴到你的代码中，关于StackOverflow的问题很多，可以告诉你怎么做。@dirkgroten，我想知道这个方法在使用模型表单时是否有效，它在做这个工作。。请注意，您永远不应该（我强调这一点，这非常重要）将模型变量直接分配给您的用户输入

book\u obj.author=request.POST.get（“author”）

非常危险！您正在将未经处理的输入保存到数据库中，这可能允许任何人向您的应用程序中注入恶意代码，包括SQL注入和XSS注入。始终使用表单的

已清理\u数据
字典。@dirkgroten，当然。。。。
