I can't figure out how to tell Dancer that my app should use development.yml under Apache. I have the following in vhosts.conf SetEnv DANCER_ENVIRONMENT "development" When I put the following fragment in config.yml, everything works db_name: "mydb" db_user: "dev" db_pass: "dev" When I take the above out of config.yml, and put it in development.yml, all the config->{} values are empty. For example, I get the following error in my Apache log DBI connect('dbname=','',...) failed: FATAL: because, my code is my $dbh = DBI->connect( "dbi:Pg:dbname=" . config->{db_name}, config->{db_user}, config->{db_pass}, {AutoCommit => 0} ); If I put the above in development.yml, and put the following in production.yml, it fails because it can't find the prod databases db_name: "mydb" db_user: "prod" db_pass: "prod" It is almost as if development.yml is not being seen at all. It is being bypassed. Maybe that also explains why I am not getting any development.log. Any ideas? I am using Dancer 1.3011. Puneet,
