    text
    copied!<p>I am trying to create a gem with a generator for Rails 3 (beta 4). I followed <a href="http://www.railsdispatch.com/posts/how-rails-3-enables-more-choices-part-1" rel="noreferrer">these instructions</a>, and but I couldn't get it running. The problem is that when I am defining a module in the generator file, the generator gets listed with 'rails generate', but can't get executed because the generator isn't found.</p> <p>From the instructions (doesn't work with 'rails generate my_gem:install'):</p> <pre><code>module MyGem class InstallGenerator &lt; Rails::Generators::Base source_root File.expand_path("../templates", __FILE__) # all public methods in here will be run in order def add_my_initializer template "initializer.rb", "config/initializers/my_gem_initializer.rb" end end end </code></pre> <p>Modified (works with 'rails generate install):</p> <pre><code>class InstallGenerator &lt; Rails::Generators::Base source_root File.expand_path("../templates", __FILE__) # all public methods in here will be run in order def add_my_initializer template "initializer.rb", "config/initializers/my_gem_initializer.rb" end end </code></pre> <p>However, I want to have namespaces for the generator, e.g. company:gem_name:generator, for which I have to use the module approach (I think). My guess is that it has something to do with the lookup and the directory structure, but I couldn't figure out how. I tried a couple of approaches:</p> <pre><code>lib -generators --my_gem.rb lib -generators --company ---my_gem.rb lib -generators --company ---my_gem_name ----my_gem.rb </code></pre> <p>but nothing helped. I also found quite a bit on the Internet, but non if showed what I needed.</p>
