Look in your Views directory.
Do you see a Llamada folder with llamada.rhtml inside it?
You shouldn't because that is the file your app is looking for.
You need to create a View template named llamada.rhtml for the information to appear in.
You're welcome.
Just try putting a file named llamada.rhtml in the establishment_contents folder and see what happens.
Every time I get a "TEMPLATE MISSING" error, it has meant I have failed to create a file to contain the output of the method.
the output needs a place to go. if you have a different view to display the results... user the render command
render :action => "other_action_name"
or
render :partial => "other_action_partial
