Hi,
I am new to yesod and following the documentation to make a form. In the documentation the form template was created in .hs file itself. But I have a separate hamlet where I want to customize.
I want to access "fields" in my hamlet file. The expected type of 'generateFormPost' is (xml, Enctype) . Can anybody tell me what I should be returning from 'tableMform extra' . I think it should be in xml format. But I think I should not be using toWidget as in below example of documentation.
tableMform extra = do fields <- forM lis (\(w,h) -> mopt intField "this is not used" (Just h) ) return (fields) ---I know this line has the type error. Can anybody suggest how to deal with it
{- --I am referring this code from yesod website to make my form. In this it was using runFormGet, but I want use generateFormPost and moreover it was creating a widget which is used in displaying the website. I don't want to create the widget here but in my hamlet file where the 'fields' is accessed via interpolation.
personForm :: Html -> MForm Handler (FormResult Person, Widget) personForm extra = do (nameRes, nameView) <- mreq textField "this is not used" Nothing (ageRes, ageView) <- mreq intField "neither is this" Nothing let personRes = Person <$> nameRes <*> ageRes let widget = do toWidget [lucius| ##{fvId ageView} { width: 3em; } |] [whamlet| #{extra} <p> Hello, my name is # ^{fvInput nameView} \ and I am # ^{fvInput ageView} \ years old. # <input type=submit value="Introduce myself"> |] return (personRes, widget)
-}
getHomeR :: Handler Html getHomeR = defaultLayout $ do -- Generate the form to be displayed (fields, enctype) <- generateFormPost tableMform let (fires,fiview) = unzip fields $(widgetFile "layout") |]
Please let me know if there is any misunderstanding. I have idea of how to get the form from the way done in the documentation, but I want to use a separate hamlet file, as I want to customize the look of the form.
