【问题描述】:
我遇到了一个问题,我的 Laravel 的 Eloquent 模型没有为我提供名为“id”的列的值,它只是变成整数 (0) 而不是字符串。我虽然该列以某种方式受到保护,但在“id”是整数的其他模型中,它返回值就好了。
问题:我不能对主键使用 VARCHAR 吗?
注意:我必须创建更多具有相应模型的表,其中主键需要是字符串;我有点新 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');
});
模型真的很简单:
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
但如果我使用 print_r() 函数,这是输出:
App\Http\Models\Country\Country Object
