由 谁都会走 提交于 2019-11-27 01:55:21
问题 Hi Stackoverflow people, In my clean function in forms.py, I would like to save automatically some information in a session variable. However, I do not seem to get access to the request variable.

问题 I am trying to realize a Class Based ListView which displays a selection of a table set. If the site is requested the first time, the dataset should be displayed. I would prefer a POST submission, but GET is also fine. That is a problem, which was easy to handle with function based views , however with class based views I have a hard time to get my head around. My problem is that I get a various number of error, which are caused by my limited understanding of the classed based views. I have

Multiple form classes in django generic (class) views

由 寵の児 提交于 2019-11-26 14:16:01

For example in the inline_formset example in the django docs, I would want to present a page where an author and his books can be edited

How to use permission_required decorators on django class-based views
