Junk In The Trunk Free Clips

One of the plugins that make up the meta-rails project (
http://meta-rails.rubyforge.org
)

is charged with making a diagram of the application class and provides a query generator
• these classes. To do this I needed to load drivers and their views
directly from this plugin.

• after documenting and testing I have found a way to make it easy.



Upload
• drivers
All ruby \u200b\u200bon rails plugins can have the file in your root folder init.rb
running when loading rails application. This file is the hook (hook) which can be used to introduce
• plugin code in the Rails application.

If we put our drivers in the plugin subdirectory app / controllers to load
• can use the following code:

directory = "# {RAILS_ROOT} / vendor / plugins / NOMBRE_DEL_PLUGIN"

controller_path = File.join (directory , 'app', 'controllers') require "# {controller_path} / NOMBRE_DEL_CONTROLADOR.rb"

$ LOAD_PATH
if defined? (RAILS_GEM_VERSION) and RAILS_GEM_VERSION> = '1 .2.0'
Dependencies.load_paths

else raise "Engines plugin is Needed for running NOMBRE_DEL_PLUGIN with \\
Ruby on Rails version config.controller_paths
end

  
 Analyzing the code we see that this code is executed differently depending 
 use Ruby on Rails version 1.2.0 or later to previous. This is because to work 
 in versions prior to 1.2.0 we need the engines plugin installed ( http://rails-engines.org 

). Once

put this code we can create our drivers doing that inherit from ActionController:: Base class

  
  MetaQuerierController 

def index render: text => "It works!" End end

Views

for our drivers

Once we loaded the drivers, we must assign
1. subdirectories where they can find their views. We do this by changing a class variable with self.template_root:
   MetaQuerierController
   self.template_root
   class = "# {RAILS_ROOT} / vendor / plugins / meta_querier / app / views /" end
