Method HandleError

mvc/mvc.go:342–348

HandleError registers a `hero.ErrorHandlerFunc` which will be fired when application's controllers' functions returns an non-nil error. Each controller can override it by implementing the `hero.ErrorHandler`.

(handler func(ctx *context.Context, err error))

// application's controllers' functions returns an non-nil error.
// Each controller can override it by implementing the `hero.ErrorHandler`.
func (app *Application) HandleError(handler func(ctx *context.Context, err error)) *Application {
	errorHandler := hero.ErrorHandlerFunc(handler)
	app.container.GetErrorHandler = func(*context.Context) hero.ErrorHandler {
		return errorHandler
	}
	return app
}

// Clone returns a new mvc Application which has the dependencies
// of the current mvc Application's `Dependencies` and its `ErrorHandler`.
