Instance Method Details

#after(*dependencies, &block) ⇒ Object

Run this seed after the specified dependencies have run If a block is specified the contents of the block are executed after all the dependencies have been executed.

If no block is specified just the dependencies are run. This makes it possible to create shared dependencies. For example

Would look for a db/seeds/shared/users.seeds.rb seed and execute it.

Examples:

db/seeds/production/users.seeds.rb

after 'shared:users'
