func AddHelper ¶

func AddHelper(name string, f interface{})

AddHelper registers functions with TemplateBroker that will be available in templates during rendering.

func TemplateBroker ¶

func TemplateBroker(r *gadget.Request, status int, body interface{}, data *gadget.RouteData) (int, string)

TemplateBroker attempts to render interface{} value body as the context of a html/template.Template. It requires adherence to a few simple conventions for locating templates: 1) all templates are inside a "templates" directory in the root directory of the Gadget application; 2) a "templates/base.html" file exists and can be parsed as a Go template; 3) templates will be loaded from a directory matching the lower-cased plural name of the controller and the lower-cased name of the action, plus the extension ".html". For example, the Show method of a FavoriteController would look for a template "templates/favorites/show.html."

All error codes can also be served via their own templates. Non-200 statuses will result in TemplateBroker looking for a "templates/403.html", "templates/502.html", etc.
