This feature is also known as the Nova 'Traffic Cop'. This has been an issue since the introduction of Office 2011, but it only occurs when using the Borders button on the Ribbon. This may occur if another user updates the model after you have opened the 'Edit' page on the resource. If a model has been updated since it was last retrieved by Nova, Nova will automatically respond with a 409 Conflict HTTP status code and display an error message to prevent unintentional model changes. Use App \Models \User use App \Nova \Resource use Illuminate \Database \Eloquent \Model use Laravel \Nova \Http \Requests \NovaRequest class User extends Resource # Preventing Conflicts
