Ruby loop question and dumping results into YAML file

I am working on a Ruby script that will dump a key, value pair into a yaml file. But for some reason my loop is only grabbing the last instance in the loop. There should be multiple key value pairs.

Code:

# Model for languages Table
class Language < ActiveRecord::Base
end

# Model for elements Table
class Element < ActiveRecord::Base
  has_many :element_translations
end

# Model for element_translations Table
class ElementTranslation < ActiveRecord::Base
  belongs_to :element
end

# Find ALL languages
lang = Language.all
# Get all elements
elements = Element.where("human_readable IS NOT NULL")
info = ''

elements.each do |el|
 开发者_开发百科 lang.each do |l|
    et = el.element_translations.where("language_id = ?", l.id)
    et.each do |tran|
      info = {
        el.human_readable.to_s => tran.content.to_s
      }
    end
    File.open(l.code.to_s + ".yml", "w", :encoding => "UTF-8") do |f|
      YAML.dump(info, f)
    end
  end
end

Any ideas?

When you do:

info = {
  el.human_readable.to_s => tran.content.to_s
}

did you mean:

info << {
  el.human_readable.to_s => tran.content.to_s
}

Otherwise you're just re-assigning info each time.

If you're going to do this, make info an array: info = [] as opposed to info = ''.

In this loop

et.each do |tran|
  info = {
    el.human_readable.to_s => tran.content.to_s
  }
end

you repeatedly create new hash with one key el.human_readable.to_s with different values. However, even if you'll redo it as

info = {}
et.each do |tran|
  info[el.human_readable.to_s] = tran.content.to_s
end

you won't get more than 1 result, because key isn't changing - you'll just repeatedly assign it different values. What exactly do you want to get dumped? May be you'd want an array here, not key-value map?

info_array = []
et.each do |tran|
  info_array << tran.content.to_s
end
info = { el.human_readable.to_s => info_array }
