Question

我有以下代码返回与$ included数组中的标记关联的所有文件，这样可以正常工作。

FileObject::whereHas('tags', function($q) use ($included){
    $q->WhereIn('name', $included);
})->get())

现在我也要排除某些标签，所以我尝试下面的代码似乎不起作用。

FileObject::whereHas('tags', function($q) use ($included,$excluded){
    $q->WhereIn('name', $included)
      ->WhereNotIn('name', $excluded);
})->get())

如何创建此查询？

感谢。

返回的准备好的SQL字符串如下

select * from `fileobjects` 
where exists (
    select * from `tags` 
    inner join `taggables` on `tags`.`id` = `taggables`.`tag_id` 
    where `taggables`.`taggable_id` = `fileobjects`.`id` 
    and `taggables`.`taggable_type` = ? 
    and `name` in (?) and `name` not in (?)
)

但我需要的是这个

select * from `fileobjects` 
where 
(
    exists (
        select * from `tags` 
        inner join `taggables` on `tags`.`id` = `taggables`.`tag_id` 
        where `taggables`.`taggable_id` = `fileobjects`.`id` 
        and `taggables`.`taggable_type` = "App\\FileObject" 
        and `name` in (?)
    )
) 
and
(
    not exists (
        select * from `tags` 
        inner join `taggables` on `tags`.`id` = `taggables`.`tag_id` 
        where `taggables`.`taggable_id` = `fileobjects`.`id` 
        and `taggables`.`taggable_type` = "App\\FileObject" 
        and `name` in (?)
    )
)

解决
在我的情况下，这按预期工作

$files = FileObject::whereHas('tags', function($q) use ($included){
        $q->whereIn('name', $included);
    })->whereDoesntHave('tags', function($q) use ($excluded){
        $q->whereIn('name', $excluded);
    })->get();

Laravel Eloquent查询多个WHERE IN / NOT IN
