Active Yaml - model interfaces for yaml files

Build Status Gem Gem Version

Framework that allows you to use model classes for mapping Yaml files.


gem 'activeyaml'

And then execute:

bundle install

Or install it yourself as:

gem install activeyaml

Require if necessary:

require 'active_yaml'

Usage with model

You can create models that will take data from your Yaml files. Suppose you have the following Yaml file: examples/example.yaml. With the following content:

    lol: 'text'
    cheburek: 'cheburek'
      first: '1'

(This and all subsequent examples will use this yaml file)

Then, you could do the following:

require 'active_yaml'

class User < ActiveYaml::Base
  yaml 'examples/example.yaml'

You can then create instances of your model and use call chains to retrieve data from the Yaml file.

user = # output: 'text'
user.yaml.kek.users.first # output: '1'

If you complete the chain not to the final value. You will get an object like a hash. It won’t respond to []. However, you can use a dot to go through the values further. You can also use data from Yaml files inside your model.

class User < ActiveYaml::Base
  yaml 'examples/example.yaml'

  # The method will return "text"
  def test_method

There is also method yaml_data which will return the contents of the Yaml file as a regular hash.

user.yaml_data # will return a hash with the contents from the Yaml file

Usage without model

You also don’t have to create models to use this framework. After that, an object will be instantiated in the user variable, allowing chains of calls to be made. To do this you can do the following:

user = ActiveYaml.create('examples/example.yaml') # output: 'text'
