Laravel Eloquent CollectionWhere 列值的条件闭包

Question

我正在尝试做如下的事情:

$block = MatStock::whereHas('matDims', function (Builder $query) use ($request) {
    $query->where('width', $request->width)
        ->where('height', $request->height)
        ->where('thickness', $request->thickness)
        ->where('length', function ($column) use ($request) {
            return $column/$request->length > 0
            // how can i do that where condition?
        })
});

我的问题是在最后一个条件下。我希望我的问题很清楚。谢谢。

Answer 1

whereRaw 应该可以解决问题

->whereRaw('(length / ?) > 0', [$request->length])
