保持列名称在雄辩 [英] Reserved column names in Eloquent

问题描述

$ b $我可以看到以下实例属性：

  protected $ connection 
 protected $ table 
 protected $ primaryKey 
 protected $ perPage 
 public $ incrementing 
 public $时间戳
 protected $ attributes 
 protected $ original 
 protected $ relations 
 protected $ hidden 
 protected $ visible 
 protected $ appends 
 protected $ fillable 
 protected $ guarded 
 protected $ dates 
 protected $ dateFormat 
 protected $ casts 
 protected $ touches 
 protected $ observables 
 protected $ with 
 protected $ morphClass 
 public $ exists 
 public $ wasRecentlyCreated 
  

问题：

• 为什么这些东西不是 static ，看到他们是类级别配置东西？


• 这是否意味着我不能在表列中使用这些名称？



• 如果我有一个名为这样的列的遗留表，该怎么办？


• 谁想出了这个天才的想法？

解决方案

这些属性不能是静态的，因为他们被用作他们的模型配置。如果您在模型类中重写它们，那么您可以定义自己的参数，如果没有，那么这个Eloquent认为它应该使用默认值。
是的，您的表格中不应有与其中一个属性名称相匹配的列名。

From a cursory look into Illuminate\Database\Eloquent\Model I can see the following instance attributes:

protected $connection
protected $table
protected $primaryKey
protected $perPage
public    $incrementing
public    $timestamps
protected $attributes
protected $original
protected $relations
protected $hidden
protected $visible
protected $appends
protected $fillable
protected $guarded
protected $dates
protected $dateFormat
protected $casts
protected $touches
protected $observables
protected $with
protected $morphClass
public    $exists
public    $wasRecentlyCreated

Questions:

• Why are these things not static, seeing as they are class-level configuration stuff?
• Does it mean I cannot use these names for my table columns?
• Is there an official list of names one cannot use as table columns?
• What if I have a legacy table with columns named like this?
• Who came up with this genius idea?

解决方案

These attributes can not be static because they are used as their model configuration. If you rewrites them in your model class, you define your own parameters, if not, the Eloquent believes it should use the defaults. Yes, you should not have a column name in your table that matches the name of one of these attributes.
