Passing data between form views in Pyramid

I'm making a project in pyramid framework, so i have a view which have a form in it with 2 input type texts and a submit button.

The form is a post method, so im getting them with a POST request.

I want to send them to a new view and display them on the screen. meaning:

I tried with HTTPfound but i guess im missing an understanding on how to really pass the variables.

Please help me...

Another way to pass the data from one view to another is via the URL. This does not require server-side support, unlike sessions. Also, it's RESTful ;)

return HTTPFound('/here?greeting=Hello&subject=World')

In your second view you then simply get the variables from request.GET:

greeting = request.GET.get('greeting', '')
subject = request.GET.get('subject', '')
# pass the data to the template
return {
    "greeting": greeting,
    "subject": subject
}

Regarding your comment: You can't use HTTPFound with POST. You can, however, directly submit your form to /here using <form method="post" action="/here" ...>. In this case you'll be able to access the data using request.POST.get('greeting').

The easiest way to accomplish is to use sessions.

  • You need a session backend which stores your data on a server (see pyramid_redis_session). There are also cookie-based session solutions where all data is stored on the client side.

  • The first view writes all passed over data to a session:

    request.session["mydata"] = value

  • The second view reads data from the session

     print(request.session["mydata"])
