Thanks @keegan !
I think I got the plugin.rb file setup correctly, the loop looks correct.
However, I’m struggling on the topic-custom-field-initializer.js file. Here is my code for both files. Any pointers for the initializer.js file? I think I’m really close here, when creating a new topic, I am getting 1/3 fields, the listingDetails field but still missing the isClassifiedListing and listingStatus
enabled_site_setting :topic_custom_field_enabled
register_asset 'stylesheets/common.scss'
after_initialize do
fields = [
{ name: 'isClassifiedListing', type: 'boolean' },
{ name: 'listingStatus', type: 'string' },
{ name: "listingDetails", type: 'json' }
]
fields.each do |field|
register_topic_custom_field_type(field[:name], field[:type].to_sym)
add_to_class(:topic, field[:name].to_sym) do
if !custom_fields[field[:name]].nil?
custom_fields[field[:name]]
else
nil
end
end
add_to_class(:topic, "#{field[:name]}=") do |value|
custom_fields[field[:name]] = value
end
on(:topic_created) do |topic, opts, user|
topic.send("#{field[:name]}=".to_sym, opts[field[:name].to_sym])
topic.save!
end
PostRevisor.track_topic_field(field[:name].to_sym) do |tc, value|
tc.record_change(field[:name], tc.topic.send(field[:name]), value)
tc.topic.send("#{field[:name]}=".to_sym, value.present? ? value : nil)
end
add_to_serializer(:topic_view, field[:name].to_sym) do
object.topic.send(field[:name])
end
add_preloaded_topic_list_custom_field(field[:name])
# Serialize to the topic list
add_to_serializer(:topic_list_item, field[:name].to_sym) do
object.send(field[:name])
end
end
end
