Re: [web-devel] Yesod Examples

To be effective in haskell we have to learn how to interpret compiler error messages. For others to be effective at helping you with your problems, they need to see your compiler error messages. On Tue, Mar 29, 2011 at 12:40 PM, Zachary Kessin wrote:

Compile time error, plus I'm pretty sure the code is not actually doing what I want it to.

Like I said, I want a post method that will add a row to the database, and a get that will retrieve a list of the rows (as a JSON).

Are you getting a compile-time error, or is the result at runtime not what you expected? More details will be helpful here.

Ok, I'm trying to setup a handler to take data from a HTTP post, and store it into a database, This is what I came up with, but its not right. Can someone tell me what I am doing wrong. postPostMessageR :: Handler RepJson postPostMessageR = do liftIO $ putStrLn "POST" CharecterPost clients _ <- getYesod (text, charecter) <- do text <- lookupPostParam "text" charecter <- lookupPostParam "charecter" case (text, charecter) of (Just text', Just charecter') -> return (text', charecter') _ -> invalidArgs ["text not provided."]

jsonToRepJson $ jsonMap (("text", text'),( "charecter", charecter'))
