Bundler for Rails 3 Engine

Hello All,

My google-fu did not find this answer :

How do I configure a Rails-3 Engine so that the engine’s Gemfile is integrated with the parent-Rails-app’s bundle?

Thanks

You package your plugin as a gem, then add it as a dependency to your Rails app.

Write up a yourplugin.gemspec and put gem 'yourplugin', :path => '/to/your/plugin' in your app try.

Hi Jeremy,

I'm not sure you answered the OP's question (as I'm looking for the same answer). He wants to know, if he has a Gemfile within his gem/ engine how can he get the Rails app/Bundler to automatically load it's dependencies along with the Rails app's hardcoded dependencies.

For example, if you create your own Rails 3 Engine gem called MyShop and MyShop has a dependency on ActiveMerchant, he wants to put that dependency in a Gemfile within MyShop and not within the Rails app itself.

I agree with this (your Rails app shouldn't need to know what the dependencies are for the dependencies you have, Bundler should just take care of them) and I'm trying to do the same thing.

Cheers,

Andy

Me too. Anyone figured it out yet?

I'm looking for the same! Is it possible?

Jeremy answered the question. Really. Gemfiles are for apps, not for gems. You specify a gem's dependencies through its gemspec. Have a look at all the gems on github or try

$ gem specification activemerchant --ruby

to get an idea.

That's what bundler does. It's up to you to declare the dependencies in the appropriate way. For gems that means in a gemspec.
