[dancer-users] Dancer2::Manual: confused as to use of 'appname' keyword to distribute code across packages

[Amelia Ireland]

Hello James,

Apologies for not filling out all the modules in the app.psgi file and
adding unnecessary confusion!

The response you're getting, not being able to locate the template file, is
usually due to a config error in setting the paths to the directory your
app looks in for template files. Have you tried debugging by printing out
the 'views' parameter (see
https://metacpan.org/pod/distribution/Dancer2/lib/Dancer2/Manual.pod#TEMPLATES
)?

You can also check that the endpoints you have defined are working
correctly by returning a text string; once that is verified, you know it's
just the template engine parameters that need altering.
