create:
notice: '%{resource_name} was successfully created'
alert: ''
update:
notice: '%{resource_name} was successfully updated'
alert: ''
destroy:
notice: '%{resource_name} was successfully destroyed'
alert: '%{resource_name} could not be destroyed'You can customize it for one particular controller like this:
en:
flash:
users:
create:
notice: 'You just create a new user!'
update:
notice: 'You change it'
destroy:
notice: 'The user is no more'
alert: 'You can not delete it'
