Is it possible to use in MARKMIN editor variables, that are declared in the controller on in the model?

 

I have tested to create variables in the model and after use it in the editor as: @{variable} but nothing happend.

 

In the controller I have tried:

def index():
  variable="Hola Mundo"
  return auth.wiki(env=dict(variable=variable))

 

and after use it in the MARKMIN editor as @{variable} but nothing happend...
