Hey, sorry for the newbie question here. Have been reading the docs but need some guidance, please. I’ve forked Discourse and made my own changes, which I’d like to then do my own deploy from. The guide on contributing walks you through how to make changes and submit a PR, but in this instance, I d…

Hey @leighno5 My thoughts to you are, from personal experience, is that writing plugins for Ruby to do what you are doing in your “fork” is much easier done from a plugin, when we understand Ruby and Rails enough to easily write a plugin for Discourse (or modify any Rails class). If we don’t unde…

No you’re exactly correct. I have no experience with Ruby at all, so certainly no offense taken! I’ve seen the plug-in guide and have been through it a couple of times, but unfortunately my Ruby ignorance continues to frustrate, and I have no clue how I would write a plug-in that would override tha…

Look at existing plugin code. There are absolutely loads of them now so plenty of examples. Do not skip on reading prior art so you can leverage it. Sounds like you just want to override one method which is simply a case of redefining it in your plugin.rb (though best practice is arguably to brea…

[图片] merefield: of redefining it in your plugin.rb At the risk of further showing my ignorance and taking advantage of the kindness you’ve already shown me, would you be willing to expand on this a bit? Or if you’re aware of another example where someone has overridden a module and can link t…

Here’s one where we’ve defined a method in the PostGuardian: lib/guardian_edits.rb f4332f974 require_dependency 'guardian' require_dependency 'guardian/post_guardian' class ::Guardian attr_accessor :featured_images …

[图片] merefield: Literally just write out the original method code and make your edit. Downside: if Discourse change the code your plugin could break the instance. This is what I was worried about. Is the advanced method mentioned in your next paragraph covered in the how-to guide? Is there a …

I wouldn’t worry about the advanced method for now. Just get it working. You can research Ruby on Rails in general elsewhere in the online guides. A bit out of scope of Discourse specifically and this forum. Just be aware.

Ok cheers! Let’s say I get round to writing a short plugin. If I’ve understood it correctly, I should then check the core code on each upgrade and rewrite the plugin if the relevant core code has changed. Is that it? Thanks.
