Examples

<!--- Tell Wheels to verify that the `handleForm` action is always a `POST` request when executed --->
<cfset verifies(only="handleForm", post=true)>

<!--- Make sure that the edit action is a `GET` request, that `userId` exists in the `params` struct, and that it's an integer --->
<cfset verifies(only="edit", get=true, params="userId", paramsTypes="integer")>

<!--- Just like above, only this time we want to redirect the visitor to the index page of the controller if the request is invalid and show an error in The Flash --->
<cfset verifies(only="edit", get=true, params="userId", paramsTypes="integer", handler="index", error="Invalid userId")>
