Method: Factory.alias

Defined in:
lib/factory_girl/aliases.rb

.alias(pattern, replace) ⇒ Object

Defines a new alias for attributes.

Arguments:

  • pattern: Regexp A pattern that will be matched against attributes when looking for aliases. Contents captured in the pattern can be used in the alias.

  • replace: String The alias that results from the matched pattern. Captured strings can be substituded like with String#sub.

Example:

Factory.alias /(.*)_confirmation/, '\1'

factory_girl starts with aliases for foreign keys, so that a :user association can be overridden by a :user_id parameter:

Factory.define :post do |p|
  p.association :user
end

# The user association will not be built in this example. The user_id
# will be used instead.
Factory(:post, :user_id => 1)
