How to push keys and values into an empty hash w/ Ruby?

Question

I have a dictionary class and want to be able to push keys (as keywords) and values (as definitions) into an empty hash with an \'add\' method. I don\'t understand how to syntac

Looking at your Rspec, It looks like you need this setup.

class Dictionary
  def initialize
    @hash = {}
  end

  def add(key_value)
    key_value.each do |key, value|
      @hash[key] = value
    end
  end

  def entries
     @hash
  end

  def keywords
     @hash.keys
  end

end

Do not use key.to_sym in add method, just key

To give flexibility to add method, I can return the self object to continuesly add.

def add(key_value)
  key_value.each do |key, value|
    @hash[key] = value
  end
  self
end

So, I can do this now.

@d.add("a" => "apple").add("b" => "bat")
