I need to modify a javascript controller (create-account). If I were writing it from scratch, I’d add a mixin called something like (FooValidation), the same way the mixins PasswordValidation and UsernameValidation are applied (discourse/app/assets/javascripts/discourse/controllers/create-account.js.es6 at f03b6bd8c925163b41b9e33b39484d102dbaee44 · discourse/discourse · GitHub ). I can’t figure out how, though.
I could just add the relevant properties/methods to the create account controller using PluginApi.modifyClass, but that doesn’t feel right, especially seeing as I’ll want to reuse the mixin.
What’s the best way to achieve this?

I believe the modifyClass method accepts a mixin as an argument, so I’d try something like this:
api.modifyClass("controller:create-account", FooValidation);

Ah you’re right, modifyClass calls Ember’s reopen, which can take mixins as an argument. I couldn’t get it to work at first but I got it! Thanks!

هل يمكنك مشاركة بعض أمثلة الكود؟
أقوم بذلك في معاينات قائمة المواضيع: https://github.com/paviliondev/discourse-topic-previews/blob/master/assets/javascripts/discourse/initializers/preview-edits.js.es6
مثال محدد: api.modifyClass('component:topic-list', Settings);
لقد قمت بذلك لفصل الكود المشترك الذي كان سيتكرر لولا ذلك ويكون تقريبًا نسخة ولصق.
