Laravel：每当我返回一个模型时，总是返回一个与它的关系

发布于09月05日

I have 2 tables:

User        |   Doctor
----------  |  ----------
id          |  id
email       |  user_id
name        |  signature
last_name   |  photo
password    |  description
date_birth  |

每Doctor与User相关，但每User不一定与Doctor相关.我这样做是因为我不想使用单表继承，最终得到NULL个字段.

Is there a way to make, something like this?

// Instead of
$doctor = Doctor::with('User')->find(1);
$doctor->user->name;
// This
$doctor = Doctor::find(1);
$doctor->name;

附言:我不知道该在标题中写些什么，我应该写些什么，这样它才与问题更相关？

推荐答案

You can specify default eager loaded relationships using the $with property on the model.

class Doctor extends Eloquent {

    protected $with = ['user'];

    // ...
}

(The property might need to be public, I forget. Laravel will yell at you if it does.)

You will still need to use $doctor->user->name, but the relationship will be automatically loaded without you needing to explicitly call it. If you really want to use the $doctor->name syntax, you could create Accessors for those column names, which would then fetch and pass the appropriate User relationship columns.
