I created a select element in one edit user form with:

```
t.select :identification_type, User.identification_type_hash

```

The hash is

```
{ :type_1 => 1, :type_2 => 2, ... }

```

I need to localize type name. But I didn't find the correct way to add translation into that yml file in locale directory.

I have tryed

```
en_US:
  type_1: Translationg of type 1
  type_2: Translationg of type 1

  active_record:
    attributes:
      identification_type:
        type_1: Translationg of type 1
        type_2: Translationg of type 1

  identification_type:
    type_1: Translationg of type 1
    type_2: Translationg of type 1

```

No one above works. (while translation of other things still works.)
And I failed to find a solution in ROR document.

So what is the correct way to localize these hash value?
