Q:

How to obtain value from vars

Am trying to get value from request.vars but end up getting a null value.
My code:
if request.vars.message:
    return request.vars.message
R = request.vars.message
return dict (R=R, form =form)

My vew.html
{{=R}}
This prints none. 

A:

In your code, whenever request.vars.message has a value, it immediately returns the value (inside the if block). The only case in which the code reaches the return dict(...) line at the end is when request.vars.message is missing (technically, any falsey value, but in most cases it is probably None, meaning there is no message key in the request.vars object).
If you want to send the value of message to the view to be displayed, then do not return inside the if block.
