Question

Imagine you have a template which has a button that by clicking on it, you will will be redirected to another template to choose an item and then come back to previous template. Something like this scheme :

(Template 1)
|
|
|
*------------------ > (Template 2, with some items)
                      |
                      |
                      |
                (Select an Item)
                      |
                      |
<---------------------*
|
|    
(Template 1 , again)

But when I redirect to my previous template, it seems that I lost all of my items that I filled-in before. I just need to override one part in original template and not all of it.

Needless to say, I have two view functions: One that creates Template-1 and another one for passing the selected item to the original template !!

Answer 1

You can’t be directed to another template, you can only be directed to another view. (A template is pretty much irrelevant to the whole request/response cycle; it’s just one of the ways that Django can produce a response, but isn’t a necessary part of it and can even be used outside it, for example in sending emails.)

The way to preserve state between views is to use sessions.
