DOWNTIME_REASON = 'Adding foreign key' # When using the methods "add_concurrent_index" or "add_column_with_default" # you must disable the use of transactions as these methods can not run in an # existing transaction. When using "add_concurrent_index" make sure that this # method is the _only_ method called in the migration, any other changes # should go in a separate migration. This ensures that upon failure _only_ the # index creation fails and can be retried or reverted easily. # # To disable transactions uncomment the following line and remove these # comments: # disable_ddl_transaction! def change create_table :issue_metrics do |t| t.references :issue, index: { name: "index_issue_metrics" }, foreign_key: true, dependent: :delete, null: false t.datetime 'first_mentioned_in_commit_at' t.datetime 'first_associated_with_milestone_at' t.datetime 'first_added_to_board_at' t.timestamps null: false end end end
