Monkey patch Array so that we can find values. Used when caching some arrays

patch_arracy.rb

class Array

  # Given an Array, find if a value exists for a given key. This is helpful in our settings
  # since we cache the entire settings array, but occasionally we wan to find a specific
  # setting, i.e. "Site Title", "Posts per page", etc....
  # USAGE::: array.find_value? "key", "Value is Case Sensitive"
  
  def find_value key, value
    if self.first.respond_to? key.parameterize.underscore.to_sym
      self.select { |item| item.send(key.parameterize.underscore) == value }.first rescue nil
    else
      false
    end
  end
