Redmine

You can't only one view file gets rendered, but there are efforts to bring more hooks into views in which each plugin could in turn inject code in the view rather than superseeding it.

benjamin agullana: you can use Redmine's hooks in your plugins like the core does, if the 2 plugins are yours. Maybe engines also provides some specific render method or options, but you'll have to look deeper in their code or doc for that.

@developpers: Rails view rendering is getting better and better regarding performance. We could easily split some views into many parts and add more hooks. But maybe it has to be benchmarked, I don't know if there are performance problems with the hook mechanism.

Alright, thank you for your answers.
I don't know muck about Redmines's hooks though, could you tell me more about them?

Many informations can be found in the dedicated wiki page : Hooks

1. in the first plugin, you insert in your views a call_hook helper like this :

   <%= call_hook(:view_hook_for_my_first_plugin) %>
   

2. in the second plugin, you can use this hook by including something like this in a file required in your init.rb :

   module MySecondPlugin
     class Hooks < Redmine::Hook::ViewListener
       render_on :view_hook_for_my_plugin_1,
                 :partial => 'path/to/a/view/inserted/in/that/page'
     end
   end
   

I often use it in sidebar for instances, to avoid second plugin to erase what first one did. You can do many other things with hooks, everything shoud be in the wiki page.

Oops, render_on :view_hook_for_my_first_plugin,, not render_on :view_hook_for_my_plugin_1,

Agreed. If you (or anyone) notice any views that could be split easily, open a new feature request for it (category: Code Cleanup).
