* @method Users setGroups() 设置当前记录的“组”收藏
我想在一个用户的所有字段中设置 null。 如果这是简单的字段，例如：
* @method Users setNumber() Sets the current record's "number" value
那么我 make:
$user = $query;
$user->setNumber(NULL);
$user->save();
这个工作正常，但我想为此添加，
* @method Users setGroups() Sets the current record's "Groups" collection
但如果我 make:
$user = $query;
$user->setNumer(NULL);
$user->setUsers(NULL);
$user->save();
我有错误：
Couldn't call Doctrine_Core::set(), second argument should be an instance of Doctrine_Collection when setting many-to-many references.
第二个参数必须如何？
I would like set null in all fields in one user.
If this is simple fields, for example:
* @method Users setNumber() Sets the current record's "number" value
then i make:
$user = $query;
$user->setNumber(NULL);
$user->save();
this working ok, but i would like add for this
* @method Users setGroups() Sets the current record's "Groups" collection
but if i make:
$user = $query;
$user->setNumer(NULL);
$user->setUsers(NULL);
$user->save();
i have error:
Couldn't call Doctrine_Core::set(), second argument should be an instance of Doctrine_Collection when setting many-to-many references.
how must be the second argument for this?

即您将值设置为 Group 对象的空集合
i.e. you're making the value an empty collection of Group objects
