So, trying to use some convention over configuration i have changed my
code where my end points will be:
module/action
def action():
or
module1/module2/action
def action():
and in my utils.expose i will try to add to my views {}:
views{'modules1/action': 'myapp.module1.views.action'}
or
views{'modules1/module2/action': 'myapp.module1.module2.views.action'}
but i cant get out of 404 erro. The code:
