Question

你如何处理这种情况？在laravel这是直截了当的

$contracts = Contracts::with('bidinvitations')->with('bidinvitations.planentries)->where('created_at','2017-02-1')->get();

这样做的前提是，在 where子句旁边，列（例如 created_at ）必须来自父表（合约）。

如何查询来自另一个表的where子句，例如

$contracts = Contracts::with('bidinvitations')->with('bidinvitations.planentries)->where('bidinvitations.planentries.created_at','2017-02-1')->get();

此查询： where(**'bidinvitations.planentries.created_at'**,'2017-02-1')

只是没有工作

你可以做这样的事情

$createdAt = '2017-02-1';
$contracts = Contracts::with(['bidinvitations' => function($bidinvitations_query) use($createdAt) {
                                $bidinvitations_query->with(['planentries' =>
                                    function($planentries_query) use($createdAt) {
                                        $planentries_query->where('created_at', $createdAt);
                                    }
                                ]);
                            }])->get();

laravel-eloquent where子句来自关系表两层深
