Instance Method Details

#attributized ⇒ Object

Converts keys with hash values – e.g. posts: {} – to posts_attributes for nested forms.

Also, Allows rails specific values like _destroy or _delete.

NOTE: You must enable ‘allow_destroy: true` in your call to `accepts_nested_attributes_for` anyway, so this is secure to whitelist here.
