我有以下表格关系:
organizations
id - integer
organization_users
organization_id - integer (FK)
user_id - integer (FK)
users
id - integer
我试图通过雄辩的关系来吸引组织的所有用户。这是我的Organization.php模型及其关系:
class Organization extends Model
{
public function Users(){
return $this->hasManyThrough('App\User', 'App\OrganizationUser',
'organization_id', 'user_id', 'id');
...
}
我尝试了很多这种关系的组合,比如
return $this->hasManyThrough('App\User', 'App\OrganizationUser',
'user_id', 'organization_id', 'id');
但是所有错误都出现了同样的错误(这个错误来自第一个查询):
Illuminate\Database\QueryException with message 'SQLSTATE[42S22]: Column not
found: 1054 Unknown column 'organization_users.id' in 'on clause' (SQL: select
`users`.*, `organization_users`.`organization_id` from `users` inner join
`organization_users` on `organization_users`.`id` = `users`.`user_id` where
`organization_users`.`organization_id` = 1)'
我是否有可能让关系检索user_id以在users表上查询而不是Laravel尝试检索organization_users.id?如果没有,还有另一种解决方法吗?

这是many to many关系。
用户模型:
public function organizations()
{
return $this->belongsToMany('App\Organization','organization_users');
}
组织模式:
public function users()
{
return $this->belongsToMany('App\User','organization_users');
}
To,让所有用户加入他们的组织:
$users=User::with('organizations')->get();
foreach($users as $user)
{
print_r($user->name);
foreach($user->organizations as $organization)
{
print_r($organization->name);
}
}

您所描述的内容看起来可能是“多对多”关系。
