Question

I am trying to learn Ruby on Rails by playing around with stuff and I’m attempting to play around with Grit. However I am a bit confused coming from a PHP background where I get the repo stuff from. My code

class RepoController < ApplicationController
  require "grit"
  repo = Grit::Repo.new("blahblahblah")

  def index()
    puts YAML::dump(repo)
  end

  def show()
    repo.commits('master', 10)
    puts repo.inspect
  end
end

I am trying to dump out information on the objects, but I cannot seem to access the repo variable. My IDE and Ruby keep saying undefined local variable or method repo' and I don’t know why it cannot access the repo variable, it’s declared at the top of the class?

You’ve got scope problems. Try:

require 'grit'

class RepoController < ApplicationController
  def repo
    @repo ||= Grit::Repo.new("blahblahblah")
  end

  def index()
    puts YAML::dump(repo)
  end

  def show()
    repo.commits('master', 10)
    puts repo.inspect
  end
end
