I have seen this code in discourse_signatures plugin User.register_custom_field_type('see_signatures', :boolean) User.register_custom_field_type('signature_url', :text) User.register_custom_field_type('signature_raw', :text) if SiteSetting.signatures_enabled then add_to_serializer(:post, :user_signature, false) { if SiteSetting.signatures_advanced_mode then object.user.custom_fields['signature_raw'] else object.user.custom_fields['signature_url'] end } # I guess this should be the default @ discourse. PR maybe? add_to_serializer(:user, :custom_fields, false) { if object.custom_fields == nil then {} else object.custom_fields end } end In discourse national flags plugin User.register_custom_field_type('nationalflag_iso', :text) if SiteSetting.nationalflag_enabled then byebug; add_to_serializer(:post, :user_signature, false) { object.user.custom_fields['nationalflag_iso'] } byebug; # I guess this should be the default @ discourse. PR maybe? add_to_serializer(:user, :custom_fields, false) { if object.custom_fields == nil then {} else object.custom_fields end } end I am not able to understand what is add_to_serializer is doing. I checked in def add_to_serializer def add_to_serializer(serializer, attr, define_include_method=true, &block) klass = "#{serializer.to_s.classify}Serializer".constantize rescue "#{serializer.to_s}Serializer".constantize klass.attributes(attr) unless attr.to_s.start_with?("include_") klass.send(:define_method, attr, &block) return unless define_include_method # Don't include serialized methods if the plugin is disabled plugin = self klass.send(:define_method, "include_#{attr}?") { plugin.enabled? } end I understand that User.register_custom_field_type('signature_raw', :text) will register a custom field type to User object. But what is add_to_serializer doing? I am not able to understand, can you explain me in plain english?

Hi, When running the following code, TopicSerializer.class_eval do attributes :flag_name def flag_name object.flag_name end end I was getting the error “block in activate!': uninitialized constant TopicSerializer (NameError)”. I think I have to “import” or “require” the TopicSerializer dependency. Can you please tell me what would be the dependency, as I am not able to figure it out.

Add this directly above your code require_dependency 'topic_serializer' require_dependency 'topic_serializer' class ::TopicSerializer attributes :flag_name def flag_name object.flag_name end end

Hi thanks, but I got the error " `load’: No such file to load – topic_serializer (LoadError)". Does it pull from the app/serializers folder? I checked in that folder, I could find topic_list_serializer.rb, and many other related to topic, but couldnt find topic_serializer.rb

Right! Try TopicViewSerializer. require_dependency 'topic_view_serializer' class ::TopicViewSerializer attributes :flag_name def flag_name object.flag_name end end

Heyy, I have added a custom field to my category edit box. When I submit the form, I can see something these fields are submitted in the js console custom_fields[default_tag][]:good-feedback custom_fields[default_tag][]:one-more-tag in my main plugin file, I am doing add_to_serializer(:basic_category, :default_tag){object.custom_fields[“default_tag”]} My custom fields aren’t getting saved to the db.

[תמונה] fzngagan: in my main plugin file, I am doing add_to_serializer(:basic_category, :default_tag){object.custom_fields[“default_tag”]} My custom fields aren’t getting saved to the db. does doing: add_to_serializer(:basic_category, :default_tag, false ){object.custom_fields[“default_tag”]} now work?

I had solved it that time by adding a function on :before_action event and converted the array to a delimited string and vice versa while retrieving. I didn’t actually dig into why an array couldn’t be stored as custom field out of the box.

So this might streamline the code potentially?

Yes it would if it worked in this case. I’ll try this in sometime and get back to you.

Poor you that must’ve been painful at the time :wink:
