Laravel eloquent with Trashed on relationship
提问by S_R
I need to be able to get a Models Relationship including its soft deleted elements, but only for this 1 instance. I do not want to change the model so that every time I use the relationship it returns all the soft deleted records too.
我需要能够获得包括其软删除元素在内的模型关系，但仅限于此 1 个实例。我不想更改模型，以便每次使用关系时它也会返回所有软删除的记录。
How can I achieve this?
我怎样才能做到这一点？
User Model
用户模型
class User extends Authenticatable
{
public function contacts(){
return $this->hasMany('App\Contacts','user_id','id');
}
}
Controller
控制器
$user = User::findOrFail($id);
//Need to be able to get the trashed contacts too, but only for this instance and in this function
$user->contacts->withTrashed(); //Something like this
return $user;
How can I get the trashed rows only this 1 time inside my controller?
我怎样才能在我的控制器中只获得这 1 次垃圾行？
Thanks
谢谢

You can use withTrashedmethod in different ways.
您可以withTrashed以不同的方式使用方法。
To associate the call with your relationship you can do as follows:
要将呼叫与您的关系相关联，您可以执行以下操作：
public function roles() {
return $this->hasMany(Role::class)->withTrashed();
}
To use the same in the fly:
在飞行中使用相同的：
$user->roles()->withTrashed()->get();
For your special scenario:
对于您的特殊情况：
$user->contacts()->withTrashed()->get();

You can do this with:
你可以这样做：
$user = User::findOrFail($id);
$user->contacts()->withTrashed()->get(); //get all results
return $user;
When you call the relation with (), you can append the withTrashed()method. After that you need to get()the results.
当您使用 调用关系时()，您可以附加该withTrashed()方法。之后，你需要get()的结果。

Looking at the Laravel Documentation on Querying soft deleted models:
查看有关查询软删除模型的 Laravel 文档：
//The withTrashed method may also be used on a relationship query:
$flight->history()->withTrashed()->get();
The problem is using $user->contactsreturns collection of related records of contacts to user, while $user->contacts()will make a new query.
问题是使用$user->contacts将联系人相关记录的集合返回给用户，同时$user->contacts()会进行新的查询。
