withSqlitePool

Arguments

:: (MonadBaseControl IO m, MonadIO m) |
=> Text |
-> Int | number of connections to open
-> (ConnectionPool -> m a) |
-> m a |

withSqliteConn :: (MonadBaseControl IO m, MonadIO m) => Text -> (Connection -> m a) -> m a

createSqlitePool :: MonadIO m => Text -> Int -> m ConnectionPool

module Database.Persist.Sql

data SqliteConf

Information required to connect to a sqlite database

Constructors

Fields

sqlDatabase :: Text
sqlPoolSize :: Int

Instances

runSqlite

Arguments

:: (MonadBaseControl IO m, MonadIO m) |
=> Text | connection string
-> SqlPersistT (NoLoggingT (ResourceT m)) a | database action
-> m a |

A convenience helper which creates a new database connection and runs the given block, handling `MonadResource` and `MonadLogger` requirements. Note that all log messages are discarded.

Since 1.1.4

wrapConnection :: Connection -> IO Connection

Wrap up a raw `Connection` as a Persistent SQL `Connection`.
