Use setHeader intead

renderNotFound :: (?context :: ControllerContext) => IO () Source #

Render's a generic not found page

This can be useful e.g. when an entity cannot be found:

action ExampleAction = do
    renderNotFound

You can override the default not found error page by creating a new file at static/404.html. Then IHP will render that HTML file instead of displaying the default IHP not found page.

Constructors

PolymorphicRender
Fields html :: Maybe (IO ()) json :: Maybe (IO ())

renderPolymorphic :: (?context :: ControllerContext) => PolymorphicRender -> IO () Source #

Can be used to render different responses for html, json, etc. requests based on Accept header Example:

show :: Action
show = do
    renderPolymorphic polymorphicRender {
        html = renderHtml [hsx|<div>Hello World</div>|]
        json = renderJson True
    }

This will render Hello World for normal browser requests and true when requested via an ajax request
