To access this page, we need to set up a route to it. To do this we add to config/routing.py: | |||
<pre> | |||
map.connect('/hello_world', controller='hello_world', action='index') | |||
</pre> | |||
Now restart buildapi, and point your browser to: | |||
<pre> | |||
http://localhost:5000/hello_world | |||
