Relationship method must return an object of type Illuminate\Database\Eloquent\Relations\Relation from model call by not view in Laravel 4
提问by kaimerra
I have a model, Ability, which belongs to another model AbilityType.
我有一个模型，能力，属于另一个模型能力类型。
<?php
class Ability extends Eloquent {
public function abilityType() {
return $this->belongsTo('AbilityType');
}
public function name() {
return $this->abilityType->name;
}
}
I can make this call in my blade template successfully:
我可以在我的刀片模板中成功进行此调用：
$ability->abilityType->name
But when I make that same call in my Ability model, it throws an exception:
但是当我在我的能力模型中进行同样的调用时，它会抛出一个异常：
ErrorException Relationship method must return an object of type Illuminate\Database\Eloquent\Relations\Relation
Do the dynamic properties differ in behavior between view and model layer? What am I missing here?
动态属性在视图层和模型层之间的行为是否不同？我在这里错过了什么？
回答by Joseph Silber
Laravel uses a special getFooAttributesyntax to load dynamic properties:
Laravel 使用一种特殊的getFooAttribute语法来加载动态属性：
class Ability extends Eloquent {
public function abilityType ()
{
return $this->belongsTo('AbilityType');
}
public function getNameAttribute ()
{
return $this->abilityType->name;
}
}
