Any time you're querying a Model in Eloquent, you're using the Eloquent Query Builder. Eloquent models pass calls to the query builder using magic methods (__call, __callStatic). Model::query() returns an instance of this query builder.
Therefore, since where and other query calls are passed to the query builder:
Model::where()->get();
与以下内容相同:
Model::query()->where()->get();
Where I've found myself using Model::query() in the past is when I need to instantiate a query and then build up conditions based on request variables.
$query = Model::query();
if ($request->color) {
$query->where('color', $request->color);
}
Hope this example helps.
