Plugin using own gem

tgxworld · Septembre 12, 2016, 9:27

Gems declared in a plugin are installed and loaded differently as per our implementation:

lib/plugin/instance.rb

main


      
          def register_topic_thumbnail_size(size)
            if !(size.kind_of?(Array) && size.length == 2)
              raise ArgumentError.new("Topic thumbnail dimension is not valid")
            end
            DiscoursePluginRegistry.register_topic_thumbnail_size(size, self)
          end
          
          # Register a callback to add custom payload to Site#categories
          # Example usage:
          #   register_site_categories_callback do |categories|
          #     categories.each do |category|
          #       category[:some_field] = 'test'
          #     end
          #   end
          def register_site_categories_callback(&block)
            Site.add_categories_callbacks(enabled: method(:enabled?), &block)
          end
          
          # Add a category parameter that includes both controller param permission
          # and transactional callback. This allows plugins to extend category updates

In order to get it to work, you’ll have to specify all the gem’s dependencies which are not already included in the Gemfile.
