Hey Discourse Plugin Gurus, Just a quick question about Discourse plugins and Rails initializers. If a Discourse plugin has a directory called “config” and a subdirectory under “config” called “initializers” does the Discourse Rails app read all the plugin initializer files under the “initializers…

[image] fzngagan: After skimming through this Ruby on Rails Guides: Configuring Rails Applications Yeah, I read that Rails guide a lot lately. Basically, I’m “OK” with how Rails 6 config works (still learning, but getting more and more comfortable each day). I am just wondering if we can u…

[image] neounix: I am just wondering if we can use the same structure in a Discourse plugin (for initializers), if Rails will read the initializers in the subdirectories like they do in Rails 6; or do we have to register the plugin initializer directory as a configuration “asset” (for a lack of …

I believe so too. You load any additional Ruby files you need from within plugin.rb. Here’s an example from the Follow plugin: plugin.rb 0290c4282 after_initialize do Notification.types[:following] = 800 Notification.types[:following_p…

[image] fzngagan: Discourse doesn’t read any ruby file other than plugin.rb as far as I know. It does read the js and config files. All the ruby files have to be require d in plugin.rb. That’s kinda my impression reading though a number of Discourse plugins on GitHub. Seems Discourse only re…

[image] neounix: However, I was hoping I was wrong and there might be a “deeper” integration of Discourse plugins and Rails; as I have been getting very spoiled on how great Rails 6 is. I think there should be a way to require initializer code in plugin.rb too. Did you try this in plugin.rb …

[image] fzngagan: I think there should be a way to require initializer code in plugin.rb too. Did you try this in plugin.rb Yes, that is not a problem calling and loading the initializers in plugin.rb. The reason for my question was because I am currently writing a fairly large Rails 6 app …

Yeah, I would love those rails perks being ported to discourse plugins. One of my personal favourite would be able to live reload the ruby files without restarting the server.

[image] fzngagan: live reload the ruby files without restarting the server This is what reloadable_patch is for. If you wrap ruby class changes in reloadable_patch, it should live reload!

[image] markvanlan: If you wrap ruby class changes in reloadable_patch , it should live reload! Can I wrap the whole plugin.rb file inside it for dev? More seriously, how far can we go with it? Also, adding new files or changing any yml files needs a server restart right?

You shouldn’t have to do a reloadable_patch for everything. Many of the methods defined in instance.rb to make plugin development easy, use reloadable_patch internally like add_to_serializer. lib/plugin/instance.rb 66402abe9 @admin_route = { label: label, loc…
