在Laravel中将数组转换为雄辩的模型

Question

I have mysql table 'test' with three columns,

1.sno    2.name    4.country

this code is easily understandable

$person = \App\Test::find(1);
$person->country;         //Defined in Test eloquent model

now i want to do something like this:

$p = ['sno' => 1, 'name' => 'Joe', 'country' => '1' ];
$p->country;      //Return relevent column form countries table as defined in Model

The thing to remember is that the user i am trying to map is already present in the database table. How to i convert an array to eloquent model?

Answer 1

You could instantiate the model class with no attributes:

$dummy = new \App\Test;

Then you can call the newInstance() method:

$attributes = ['sno' => 1, 'name' => 'Joe', 'country' => '1' ];
$desiredResult = $dummy->newInstance($attributes, true);

The true flag in the method is telling eloquent that the instance already exists in database, so you can continue working with it normally. Now you can do:

$desiredResult->country //'1'
