Hi,
Coming from developing on joomla/wordpress I am curious over discourse backend file modification functionning through docker.
I have read the documentation on how to create a plugin(How can I make my own Discourse plugins? - #2 by merefield), but I don’t want to do that yet, I just want to be able to test code live
On a non docker MVC installation, doing a modification on a file via ftp, it was instantly reflected and while with docker I understand the need to rebuild the app to apply permanent modification, what if you want to test things live?
Live test code modifications don’t seem to work :
For example, I want to disable searches for anonymous users so I edited :
/var/www/discourse/app/controllers/search_controller.rb by adding “if current_user.present?” after “def show” with an end at the bottom of the function.
I was surprised that this does not have any effect on front end, and even renaming the conrolller to search_controllerold would not have any effect on the searches.
But somehow, renaming an image in /var/www/discourse/public/images# would hide the image on front-end 
!
Can anyone please tell me how things work here, is there another cached version of the system more than just the app that starts from its image?
Thank you
