No such file to load in Rails 3.1 Engines

[akremer]

Hi Pat,

This is semi-related to #230 -- I've created a Rails 3.1rc6 engine named "product" like so:

rails plugin new product --mountable -d mysql

I then created my indexable models, and added thinking_sphinx as a dependency in the engine's gemspec:

s.add_dependency "thinking-sphinx", ">= 2.0.6"

In the engine's lib/product/engine.rb, I followed #230 and ensured that any app which uses this engine adds the engine's model directory:

require 'thinking_sphinx'

module Product
  class Engine < Rails::Engine
    config.after_initialize do
      ::ThinkingSphinx::Configuration.instance.model_directories << File.expand_path('../../../app/models/', __FILE__)
    end
  end
end

The problem is that whenever I try to run any rails command inside the engine's folder (IE, to generate new models or even a migration), I get the following:

/Users/akremer/proj/product/lib/product/engine.rb:1:in `require': no such file to load -- thinking_sphinx (LoadError)

from /Users/akremer/proj/product/test/dummy/script/rails:6:in `<top (required)>'

from script/rails:6:in `<main>'

It seems like the dummy application rails creates is trying to use the engine, but not finding Thinking Sphinx even though it is listed as a dependency in the gemspec. If I run a bundle in the dummy app's folder I can see TS is being used so I don't think it's an issue with the dependency itself.

Any ideas?

Thanks for your help!

So it turns out the 2.0.6 gem was pretty much empty - I'd made a presumption on git syntax, which is now fixed, and 2.0.7 is released. Give that a shot, let me know if it fixes the problem :)

Argh! That wasn't something I had even thought of checking. That's working great now.. Thanks!

I'd be surprised if anyone had thought to check it - I'm glad @pixeltrix pointed it out to me, otherwise I would have been confused as well.

No worries -- learned more about the loading procedures of engines than I wouldve ever cared for these past few hours... A good experience :-) ------Original Message------ From: freelancing-god To: Alex Kremer Subject: Re: [thinking-sphinx] No such file to load in Rails 3.1 Engines (#278) Sent: Aug 29, 2011 00:23
