toBaseIdWitness :: ToBaseId ent => Key (BaseEnt ent) -> Key entesqueleto Database.Esqueleto.Internal.Internal Convert from the key of the BaseEnt(ity) to the key of the child entity. This function is not actually called, but that it typechecks proves this operation is safe.
useIdent :: IdentInfo -> Ident -> Builderesqueleto Database.Esqueleto.Internal.Internal Use an identifier.

esqueleto Database.Esqueleto.Legacy Record of functions to override the default behavior in mkColumns. It is recommended you initialize this with emptyBackendSpecificOverrides and override the default values, so that as new fields are added, your code still compiles. For added safety, use the getBackendSpecific* and setBackendSpecific* functions, as a breaking change to the record field labels won't be reflected in a major version bump of the library.

esqueleto Database.Esqueleto.Legacy The definition for the entity's primary key ID.
EntityIdField :: FieldDef -> EntityIdDefesqueleto Database.Esqueleto.Legacy The entity has a single key column, and it is a surrogate key - that is, you can't go from rec -> Key rec.
EntityIdNaturalKey :: CompositeDef -> EntityIdDefesqueleto Database.Esqueleto.Legacy The entity has a natural key. This means you can write rec -> Key rec because all the key fields are present on the datatype. A natural key can have one or more columns.
PersistInvalidField :: Text -> PersistExceptionesqueleto Database.Esqueleto.Legacy No documentation available.
PersistObjectId :: ByteString -> PersistValueesqueleto Database.Esqueleto.Legacy Intended especially for MongoDB backend
-
esqueleto Database.Esqueleto.Legacy Class that enables one to use toBaseId to convert an entity's key on a query into another (cf. toBaseId).
