Developing Discourse Plugins - Part 3 - Add custom site settings

I was looking how to create a site setting that validates a username, but found there’s a username type to do this. Here the list of site setting types we have today:

  • email
  • username
  • integer
  • regex
  • string
  • list
  • enum

Also, you can do custom validations for your plugin settings, it accepts a validator field that expects a Ruby class. You use it like this.

plugins:
  my_custom_username_validation:
    default: 'system'
    validator: 'UsernameSettingValidator'

You can check the UsernameSettingValidator class to see the interface of validators.

Cheers!
