Remote execution plugin missing job templates

Problem:

I installed the remote execution plugin using the “manual method” at Foreman :: Plugin Manuals.

However, it appears to not have been fully initialized. The job templates are missing when I browse over to https://my-foreman-host//job_templates. And if I try to create a template using https://my-foreman-host//job_templates/new, I get the following error: Oops, we're sorry but something went wrong undefined method job_category’ for #JobTemplate:0x00007efd128bd5b0`

Is there a way to reinitialize the data for the plugin? I haven’t started using it yet.

Expected outcome:

Should see default job templates and should be able to create a template

Hi,
most likely the database wasn’t migrated and/or seeded. rake db:migrate and rake db:seed are the commands you should be looking at.

foreman-rake db:migrate:status showed a few in a “down” state, so foreman-rake db:migrate fixed that. Pages like https://my-foreman-host/remote_execution_features began to work, but the default templates still didn’t appear. They finally appeared after I added a smart proxy to the “Remote Execution” tab when editing at subnet at https://my-foreman-host/subnets/1-10-1-122-0-25/edit
