Hi All! I'am trying to use Persist to select all entities from table but can't figure out syntax to use. Now I was able to select using fake Filter. How can I avoid fake filter and select all record?

Just use an empty list of filters, eg:
selectList [] [] 0 0 If you haven't specified types elsewhere, you can do so with a type signature like this: selectList ([] :: [Filter MyEntity]) [] 0 0 HTH, Michael

No worries. Good luck learning Haskell (and Yesod)!
