Yesod.Contrib.League.Crud.Persist

This module provides default database operations using Persist. Start out by setting crudDB = return crudPersistDefaults and then you can override any operations within your Crud instance.

Documentation

crudPersistDefaults :: CrudPersist sub => CrudDB sub

Retrieve a record of database operations that use Persist. By default, the select is limited to returning 1000 entities, so we don't end up retrieving entire large tables.

crudRunDB :: CrudPersist sub => YesodDB (Site sub) a -> CrudM sub a

Run a database query within the CrudM monad.

crudSelectList :: CrudPersist sub => [Filter (Obj sub)] -> [SelectOpt (Obj sub)] -> CrudM sub [Ent sub]

Run a selectList on the CRUD type, using the given filters and options. Return the entities as a plain pair of ObjId and Obj.

crudEntPair :: Entity t -> (Key t, t)

Helper function to convert a Persist Entity into a plain pair.
