The view need a controller to return a dict variable at least one to be
executed I think...
So maybe your controller has noting to do so you just have created a view
with the code that you want to be executed (the code that you showed us)...
Try returning a empty var from your controller if you have noting to compute
in your controller... Something like this :
def func():
a = None
return dict(a=a)
use the same controller name and view name of the function in the folder of
the dedicated controller in your view...
