Django CreateView没有保存对象

更新时间:2023-12-04 09:30:22

提示:请勿使用 exclude 在定义表单时,请使用 fields ,这是更安全的方法,也是推荐的做法。

One tip: don't use exclude when defining forms, use fields, is more secure and the recommended way to do it.

重定向是通过 get_success_url 方法定义的。如果您的模型中有方法 get_absolute_url CreateView 将重定向到该URL,否则您始终可以覆盖 get_success_url

The redirect is defined by get_success_url method. If you have in your model the method get_absolute_url CreateView will redirect to that URL, otherwise you can always override get_success_url in your view.

使用 get_absolute_url

Using get_absolute_url:

class Post(models.Model):
    user = models.ForeignKey(User)
    post_title = models.CharField(max_length=200)
    post_content = models.CharField(max_length=500)
    post_date = models.DateTimeField('date posted')

    @permalink
    def get_absolute_url(self):
        return ('myurlname', (), {'myparam': something_useful})

使用 get_success_url

Using get_success_url:

class PostCreate(CreateView):
    template_name = 'app_blog/post_save_form.html'
    model = Post
    form_class = PostForm

    def form_valid(self, form):
        form.instance.user = self.request.user
        form.instance.post_date = datetime.now()
        form.save()
        return super(PostCreate, self).form_valid(form)

    def get_success_url(self):
        return reverse('myurlname', args=(somethinguseful,))
