如果success_url与Django中的模型本身无关，该怎么办？ [英] What if success_url is irrelevant with the model itself in Django

问题描述

如果success_url由模型确定，我们可以自定义通用视图，如下所示。

If the success_url is determined by the model, we can customize the generic view as below.

def get_success_url(self):
    return '/object/%s' % (self.object.id)

但是如果success_url与模型无关，比如我们要返回页面，然后再进入表单页面。它可以是详细页面，列表页面或其他任何内容。可以将表单中的引荐网址存储吗？任何想法都不胜感激。

But if the success_url is irrelevant with the model, such as, we want to return to the page before we entered the form page. It can be a detail page, a list page, or anything else. Can I store the referral url in the form? Any idea is appreciated.

推荐答案

成功页面不会总是相同，否则您可以在 get_success_url reverse（）的URL >。
对于动态重定向，您可以像建议的一样将URL添加到表单的隐藏输入中，也可以在url的querystring中将表单发布到（例如， / myurl？next = /重定向-URL / ）。那么你可以在你的视图类中执行以下操作：

I assume that the success page will not always be the same as otherwise you could just include the url with something like reverse() in get_success_url. For a dynamic redirect you could either, like you suggested add the url in a hidden input to the form or in the querystring of the url the form is posted to (eg. /myurl?next=/redirect-url/). Then you could do in your view class something like:

# url is in the form in a hidden input 'next'
def get_success_url(self):
    return request.POST['next']

# url is in the query string ?next=xxxx
def get_success_url(self):
    return request.GET['next']
