Laravel Eloquent 在数据特定字段上使用 where

Question

这是我的代码：

$course = Course::where('id', $activeCourseId)
        ->with(["blocks.cards" => function($q) use($cardsDueIds) {
            $q->whereNotIn('blocks.cards.id', $cardsDueIds);
            $q->take(50);
        },
        "cards",
        "blocks.cards.contexts",
        "blocks.cards.user_contexts",
        "blocks.cards.block.course",
        "blocks.cards.thisUser"])
        ->first();

我尝试只获取 block.cards，其中每个 block.cards[’id'] 都不在 $cardsDueIds。

实际上我有这个错误“

Unknown column 'blocks.cards.id' in 'where clause'

".

有人知道如何正确执行此操作吗？谢谢！

Answer 1

试试这个，

$course = Course::where('id', $activeCourseId)
          ->with(["blocks.cards" => function($q) use($cardsDueIds) {
               $q->whereNotIn('id', $cardsDueIds);
        }])
        ->first();

Answer 2

$q->whereNotIn('blocks.cards.id', $cardsDueIds);

至

 $q->whereNotIn('id', $cardsDueIds);

因为你已经处于那种关系中所以回电
