我遇到了一个问题,我的Laravel's Eloquent Model没有给我一个名为' id'它只是变成一个整数(0)而不是一个字符串。虽然这个专栏在某种程度上得到了保护,但在其他模型中,其中包括“#id;'是一个整体,它返回的价值就好了。
问题:我不能使用VARCHAR作为主键吗?
注意:我必须创建更多具有相应模型的表,其中主键必须是字符串;我有点新的Laravel
迁移:
Schema::create('country', function (Blueprint $table) {
$table->engine = 'InnoDB';
$table->string('id', 5);
$table->string('name', 45);
$table->string('currency_symbol', 5);
$table->string('currency_name', 45);
$table->float('tax_rate');
$table->string('url')->nullable();
$table->string('support_email', 90);
$table->string('noreply_email', 90);
$table->boolean('active');
$table->boolean('root');
$table->primary('id');
});
模型非常简单:
use Illuminate\Database\Eloquent\Model;
class Country extends Model
{
protected $table = 'country';
}
但是当我试图找回它时......
echo Country::find('ve')->first()->toJSON();
//Output:
{"id":0,"name":"Test","currency_symbol":"T".....
// And...
var_dump(Country::find('ve')->first()->id);
//Output:
int:0
但是如果我使用print_r()函数,那么这就是输出:
App\Http\Models\Country\Country Object

如果您的主键不是自动递增值,那么您需要让模型知道它不是。否则,它会自动尝试将主键转换为整数。
因此,请尝试将此添加到模型中,然后检索值。
public $incrementing = false;
需要注意的另一点是,在使用first()
方法时,无需致电find()
。在幕后,它已经为你做了,所以你可以缩短它:
Country::find('ve')->id;
