by Knut Olav Bøhmer 02 Jan '11

Hi, Can anyone help me extend the "Random bananas" example from http://docs.yesodweb.com/book/forms/ to include a fileField, so that I can understand how to use the fileField. I have tried something like this: data Params = Params { minNumber :: Int , maxNumber :: Int , singleWord :: String , pluralWord :: String , fileTest :: FileInfo } paramsFormlet :: Maybe Params -> Form s m Params -- Same as: paramsFormlet :: Formlet s m Params paramsFormlet mparams = fieldsToTable $ Params <$> intField "Minimum number" (fmap minNumber mparams) <*> intField "Maximum number" (fmap maxNumber mparams) <*> stringField "Single word" (fmap singleWord mparams) <*> stringField "Plural word" (fmap pluralWord mparams) <*> fileField "test" (fmap fileTest mparams) I have problems understanding what's going on here. Regards -- Knut Olav Bøhmer

Yesod internal error reporting
by Aur Saraf 02 Jan '11

Hi, Yesod currently reports internal server errors in a way that is very hard to debug, in my opinion - with many "..." instead of text (I am thinking specifically about the SQL error I have in front of my eyes, but I'm pretty sure I've seen it with other errors too). How hard would it be to improve this? Or was this fixed in a newer version than I'm using? Thanks, Aur

rendering hamlet (esp julius) manually
by Max Cantor 01 Jan '11

I was wondering how to render a hamlet template (I'm specifically interested in julius - more on that later) outside of the context of a Handler handling a web request. The reason I want to do this is I have come client side javascript (for android and ios + phonegap) and it would be nice to use julius to automatically generate some javascript code for the xcode project. To be specific, i have a .js file like this: var URL_HOME = "http://localhost"; // var URL_HOME = "http://myhost"; var URL_PROFILE = URL_HOME + "/boo"; If its possible to render julius without a request, then I could do this: var URL_HOME = @HomeR@; var URL_PROFILE = @ProfileR@; and add a small executable to generate the JS file. So, how would one do this? Sorry if this is obvious, i spent some time trying and digging around the haddocks, didn't find an answer. happy new years, max
