specific theme per project

Added by Vianney Lecroart over 15 years ago

Hello,

I wanted to have different themes for different project.

In themes.rb, I changed this:

    @current_theme ||= Redmine::Themes.theme(th)

with:

    th = Setting.ui_theme
    if not @project.nil?
      th << "_#{@project.identifier}" 
    end
    @current_theme ||= Redmine::Themes.theme(th)

Then, I created different themes like:

classic_proj1/
classic_proj2/

The strange thing is that it almost works but when I do a force refresh with the browser, it displays classic theme instead of the proj1 one.
Is it a cache issue or something?
Have you a better idea to do that?

Hello,

I have found where was your issue.

In your code, just change this :

th = Setting.ui_theme

by this

th = String.new(Setting.ui_theme)

The problem was that the _=_ just copy the pointer and not the value.

Thank you François,

It works fine now, I see that I lack some knowledge in ruby :/

My company has adapted this patch slightly to be more robust. We've added checking for the existence of the per-project theme so that it will default to the global theme if no per-project one exists. Our version also removes the prefix on the per-project theme, since for our site most of the per-project themes have little to do with the overall theme, and the overall theme for our site seldom changes. As a side note, we find that the easiest way to manage per-project themes is to simply create symlinks to other themes, unless there's actual per-project customization for a given project.

Here is a patch containing our changes:
