persistManyFileWith :: PersistSettings -> [FilePath] -> Q Exppersistent Database.Persist.TH Same as persistFileWith, but uses several external files instead of one. Splitting your Persistent definitions into multiple modules can potentially dramatically speed up compile times. The recommended file extension is .persistentmodels.
Examples
Split your Persistent definitions into multiple files (models1, models2), then create a new module for each new file and run mkPersist there:-- Model1.hs share [mkPersist sqlSettings] $(persistFileWith lowerCaseSettings "models1")
-- Model2.hs share [mkPersist sqlSettings] $(persistFileWith lowerCaseSettings "models2")
Use persistManyFileWith to create your migrations:-- Migrate.hs mkMigrate "migrateAll" $(persistManyFileWith lowerCaseSettings ["models1.persistentmodels","models2.persistentmodels"])
Tip: To get the same import behavior as if you were declaring all your models in one file, import your new files as Name into another file, then export module Name. This approach may be used in the future to reduce memory usage during compilation, but so far we've only seen mild reductions.
