Client side

setupUnsyncedClientQuery

Arguments

:: (PersistEntity clientRecord, PersistEntityBackend clientRecord ~ SqlBackend, MonadIO m)

=> (a -> clientRecord)

How to insert a _new_ record

-> [a]

-> SqlPersistT m ()

Setup an unsynced client store

You shouldn't need this.

setupClientQuery

Arguments

=> (a -> clientRecord)

Create an un-deleted unsynced record on the client side

-> (sid -> a -> clientRecord)

Create an un-deleted synced record on the client side

-> (sid -> clientRecord)

Create an deleted synced record on the client side

-> ClientStore (Key clientRecord) sid a

-> SqlPersistT m ()

Setup a client store

You shouldn't need this.

clientGetStoreQuery

Arguments

:: (Ord sid, PersistEntity clientRecord, PersistField sid, PersistEntityBackend clientRecord ~ SqlBackend, MonadIO m)

=> (clientRecord -> a)

How to red a record

-> EntityField clientRecord (Maybe sid)

The server id field

-> EntityField clientRecord Bool

The deleted field

You shouldn't need this.

Server side side

serverGetStoreQuery

Arguments

:: (PersistEntity record, PersistEntityBackend record ~ SqlBackend, MonadIO m)

=> (record -> a)

How to read a record

-> SqlPersistT m (ServerStore (Key record) a)

You shouldn't need this. This uses insertKey function and is therefore unsafe.
