Callbacks
factory_bot makes six callbacks available:
| Callback | Timing |
|---|---|
| before(:all) | called before any strategy is used to construct an object, including custom strategies |
| before(:build) | called before a factory builds an object (via FactoryBot.build or FactoryBot.create) |
| after(:build) | called after a factory builds an object (via FactoryBot.build or FactoryBot.create) |
| before(:create) | called before a factory saves an object (via FactoryBot.create) |
| after(:create) | called after a factory saves an object (via FactoryBot.create) |
| after(:stub) | called after a factory stubs an object (via FactoryBot.build_stubbed) |
| after(:all) | called after any strategy has completed, including custom strategies |
Examples
Calling an object's own method after building
##
# Define a factory that calls the generate_hashed_password method
# after the user factory is built.
#
# Note that you'll have an instance of the object in the block
#
factory :user do
after(:build) { |user, context| generate_hashed_password(user) }
end
Skipping an object's own :after_create callback
##
# Disable a model's own :after_create callback that sends an email
# on creation, then re-enable it afterwards
#
factory :user do
before(:all){ User.skip_callback(:create, :after, :send_welcome_email) }
after(:all){ User.set_callback(:create, :after, :send_welcome_email) }
end
