How to modify a gem?

Question

I have a gem to which I'd like to do few changes.

I have it defined in my Gemfile as follows:

gem 'mongo_mapper", :git => "git://github.com/jnunemaker/mongomapper", :branch => "rails3" 

I was not able to find it in /usr/local/ruby/lib/ruby/gems/1.9.1/gems.

Answer 1

I'm not quite sure what you mean.

Do you mean you want to override the behaviour of the gem's code?

Is this the question you are asking:

"I'm using a gem in my Rails project, and want to change it's behaviour slightly. Given that this is the gem in question (as specified in my Gemfile), how would I go about this?"

Answer 2

bundle show mongo_mapper
