在Django表单上绑定不同的表单是什么？

Question

I'm working on a Project where some old code is and I found a part where I'm not really know what it does.

Here

form = UserForm(request.REQUEST)

What I normally do is

form = UserForm(request.POST)

What is the difference between this both snippets. What does request.REQUEST in the form?

Thanks

Answer 1

It gives you either request.POST or request.GET , but not recommended to use.

From HttpRequest reference

HttpRequest.REQUEST

For convenience, a dictionary-like object that searches POST first, then GET. Inspired by PHP's $_REQUEST.

For example, if GET = {"name": "john"} and POST = {"age": '34'}, REQUEST["name"] would be "john", and REQUEST["age"] would be "34".

It's strongly suggested that you use GET and POST instead of REQUEST, because the former are more explicit.

Answer 2

You could have looked up the documentation for request.REQUEST :

For convenience, a dictionary-like object that searches POST first, then GET.

Perhaps the authors of this code did not know if the form would be submitted via POST or GET, so used REQUEST to make sure they caught both.
