Redmine

Actually Mephisto is in the process of throwing their plugin system away and using Engines instead. You should be able to create a Redmine or Rails plugin to override anything in Redmine without changing the core.

Hey Eric,

I really tried to overload existing redmine-views and -controllers with engines for several days - but couldn't get it to work.. :(

Will try it again :)

@Jean-Philippe: Would it be possible that I could get write access to http://www.redmine.org/wiki/redmine/Plugins that I can add some documentation about my experiences writing redmine plugins?

+1. As the Engines docs say, you can't really clobber models with a plugin - you'd have to copy the whole existing model into the plugin, which kind of defeats the purpose. I was able to get it to work for one page load with some evil hackery, but at the end Rails insists on loading the original plugin.

-1.

I have to disagree. I'm working on a Redmine plugin and the engines system has worked very well, I think a "real" plugin system would require a huge amount of effort to even reach the same level. Models can be a problem, true, but it's not difficult to inject code into existing models in the plugin initialization code. I added a new has_many association to projects in this way. Some problems can occur in development mode because of reloading, but they can be worked around.

Martin Liu: you should be able to edit the wiki now.

Hi, Brian.
Could you tell us how to do this? "I added a new has_many association to projects in this way."
Thanks.

This code is working great for me. As you can see in the ClassMethods and InstanceMethods modules, you can easily add or override methods in the Redmine core.

# init.rb
require_dependency 'issue_patch'

# issue_patch.rb
require_dependency 'issue'

module IssuePatch
  def self.included(base) # :nodoc:
    base.extend(ClassMethods)

    base.send(:include, InstanceMethods)

    # Same as typing in the class 
    base.class_eval do
      belongs_to :my_plugin_class
    end

  end

  module ClassMethods   
    # Methods to add to the Issue class
  end

  module InstanceMethods
    # Methods to add to specific issue objects
  end
end

# Add module to Issue
Issue.send(:include, IssuePatch)

Hi,
In my redmine application i added some plugins while overriding a same patch in different plugin but it take priority with the top level i unable to run my bottom plugin patch.

For Example:

Plugin 'A'   Am writing patch for issues controller and issue before_save callBack
   plugin 'B'   Am overriding same issue controller patch and model before_save callBack

The above scenario Plugin 'A' patch's only running plugin 'B' code does't run

Any one have any solution for this?
