findOrFail Laravel 5 function for specific field
提问by pavlenko
This is my code:
这是我的代码：
$get_all = Geo_Postal_us::findOrFail($postal);
With this query, Laravel tries to find the idfield in the table.
通过这个查询，Laravel 尝试id在表中查找字段。
I don't have an idfield. I use the postalcolumn as primary key.
我没有id领域。我使用该postal列作为主键。
How do you set the function to find value in postalcolumn and not search from idcolumn?
您如何设置函数以在postal列中查找值而不是从id列中搜索？
Thanks,
谢谢，

You could create the behaviour you are looking for with the following:
您可以使用以下内容创建您正在寻找的行为：
Geo_Postal_us::where('postal', $postal)->firstOrFail();

Laravel by default is searching for the "id" column inside the table if you are using find(). To avoid running into errors here and maybe later, you should always tell laravel that you did take another name for your primary field.
如果您使用 find()，Laravel 默认会在表中搜索“id”列。为了避免在这里或以后遇到错误，你应该总是告诉 laravel 你确实为你的主要字段取了另一个名字。
To do that, in your Geo_Postal_us just edit as the following:
为此，在您的 Geo_Postal_us 中只需编辑如下：
class Geo_Postal_us extends Model
{
protected $primaryKey = 'postal'; //tell laravel to use 'postal' as primary key field
