complement-migrationclj

(complement-migration conn migration)

If migration contains tx-data, function returns migration unchanged. If it contains tx-data-fn instead then it evaluates resolved symbol and merges the result with migration.

ensure-installedclj

(ensure-installed conn migration)

Ensure that migration is installed, be it schema, data or otherwise. A migration is represented in a format of a map with kv pairs:

:id - unique identifier of the migration. The id needs to be of type clojure.lang.Keyword. No migrations having same id will get installed after this one has been installed. :tx-data - a vector of datoms to be transacted if migration is not installed yet. :tx-data-fn - an alternative to :tx-data. It's a symbol representing a function that will be ran to produce tx-data. The function will be ran with one argument - conn.

If migration hasn't been installed before then function will return with a transaction result. It will return ::already-installed otherwise.
