Rails: shell command in controller

I'm trying to run shell command with rake task of another project in rails controller:

def generate
  render json: `cd /Users/user/project && rvm use ruby-2.1.1@gemset && bundle exec rake users:build`
end

The problem is that not working for that task (nothing happening) but if I run rake routes for example it is running well.

if you are running another ruby project, make sure you clean the current bundler environment before run command. Bundler provides an easy way to tackle this inconvenient by doing:

 Bundler.with_clean_env{   
    render json:  `cd /Users/user/project  && rvm use ruby-2.1.1@gemset && BUNDLE_GEMFILE=path/to/Gemfile bundle exec rake users:build`
 }

take note of BUNDLE_GEMFILE and Bundler.with_clean_env

Best!

Instead of issuing a system call, can you try this (place the following snippet in your controller file):

require 'rake'

Rake::Task["users:build"]
