Instance Method Details

#has_child_profile_fields(*keys) ⇒ Object

This creates an easier way to access a composed ProfileField’s child field values. Instead of calling 

.children.where( :label => :account_number ).first.value
.children.where( :label => :account_number ).first.value = "12345"

you may call

.
. = "12345"

after telling the profile_field to create these accessors:

class BankAccount < ProfileField
  ...
  has_child_profile_fields :account_holder, :account_number, ...
  ...
end

Furthermore, this method modifies the intializer to build the child fields on build of the main profile_field.
