Reading, Updating and Adding to a yml file using Ruby on Rails

Question

I have one yml file.. Its structure is as follows.

en:
  hello: "Hello world"
  menu:
    profile: "My Profile"
    my_risk: "My Risk"
  header:
    profile: "My Profile"
    my_risk: "My Risk"

And when I am able to get the value of yml file using

yml_content = YAML.load_file('config/locales/en.yml')
p yml_content['en']

What i want to know is how to get the value profile alone which is inside menu of en Also i want to know whether we can add a new object like my_abc: "ABC" inside menu using ruby.

Thanks in advance

Answer 1

When you parse a YAML you get a Hash. So to get into an inner element, all you need to do is:

p yml_content['en']['menu']['profile']
# => "My Profile"

Also, since it is a hash, all you need to do to add to it, is simply assign a new key-value to it:

yml_content['en']['menu']['my_abc'] = "ABC"
