Module Database.ERD.Generic

showDatabaseKey :: String -> (a -> Int) -> a -> String   

Shows a database key for an entity name as a string. Useful if a textual representation of a database key is necessary, e.g., as URL parameters in web pages. This textual representation should not be used to store database keys in attributes!

readDatabaseKey :: String -> (Int -> a) -> String -> Maybe a   

Transforms a string into a key for an entity name. Nothing is returned if the string does not represent a reasonable key.

newEntry :: Show a => (Int -> a -> Dynamic) -> (Int -> a -> b) -> a -> Transaction b   

Insert a new entity and assign a new key for it.

newEntryR :: (Show a, Show b) => (Int -> (a,b) -> Dynamic) -> a -> b -> Transaction ()   

getEntry :: (Read a, Show a) => (Int -> a -> Dynamic) -> (Int -> a -> b) -> Int -> Transaction b
