This is generally not recommended as there might be multiple instances during a request cycle (f.e. when using sub-requests). Instead, it is recommended to inject the RequestStack and retrieve the current request each time you need it via `getCurrentRequest()`. Loading history...

			0 ignored issues – show Bug introduced 2019-01-09 20:30 UTC by Report Bug Copy Issue Report The method `orderBy()` does not exist on `Illuminate\Database\Eloquent\Builder`. Did you maybe mean `enforceOrderBy()`? This check marks calls to methods that do not seem to exist on an object. This is most likely the result of a method being renamed without all references to it being renamed likewise. Loading history...
