Laravel ORM Array to String Conversion
提问by Mark Karavan
Laravel 5.3, PHP 5.6
Fresh laravel newproject, minimal configuration.
Laravel 5.3，PHP 5.6 Freshlaravel new项目，最少配置。
I have made a simple migration and model, and am trying to seed data into it via php artisan tinker.
我做了一个简单的迁移和模型，并试图通过php artisan tinker.
My migration looks like this:
我的迁移如下所示：
<?php
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;
class CreatesFooTable extends Migration
{
/**
* Run the migrations.
*
* @return void
*/
public function up()
{
Schema::create('foo', function (Blueprint $table) {
$table->increments('id');
$table->string('foo', 20);
$table->timestamps();
});
}
/**
* Reverse the migrations.
*
* @return void
*/
public function down()
{
Schema::dropIfExists('foo');
}
}
When I run php artisan migratethe database populates just fine.
当我运行php artisan migrate数据库填充就好了。
The corresponding model is simple:
对应的模型很简单：
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
class Foo extends Model
{
protected $table = 'foo';
protected $fillable = ['foo'];
}
I have a ModelFactory as well:
我也有一个 ModelFactory：
$factory->define(App\Foo::class, function (Faker\Generator $faker) {
return [
'foo' => $faker->email,
];
});
Tinker does what I think it should do when I try to makea flyer from the factory:
当我尝试make从工厂制作传单时，Tinker 做了我认为应该做的事情：
>>> factory('App\Foo')->make();
=> App\Foo {#696
foo: "[email protected]",
But when I try to hit the database, Eloquent fails to wrap the query values in a string:
但是当我尝试访问数据库时，Eloquent 无法将查询值包装在字符串中：
>>> $foo = factory('App\Foo')->create();
Illuminate\Database\QueryException with message 'SQLSTATE[22001]: String data, right truncated: 1406 Data too long for column 'foo' at row 1 (SQL: insert into `foo` (`foo`, `updated_at`, `created_at`) values ([email protected], 2016-09-06 23:59:03, 2016-09-06 23:59:03))'
Nothing like this on Google. Any ideas?
谷歌上没有这样的东西。有任何想法吗？

Some of the faker methods return their result as an array, as a default. For example:
默认情况下，一些 faker 方法将其结果作为数组返回。例如：
$faker->words(3)
would return:
会返回：
array('porro', 'sed', 'magni')
To return the result as a string you can pass trueas the second argument for some methods, as in the previous example using the wordsmethod:
要将结果作为字符串返回，您可以true作为某些方法的第二个参数传递，如使用该words方法的前一个示例：
$faker->words(3, true)
returns:
返回：
"porro sed magni"
As described in the readme:
如自述文件中所述：
words($nb = 3, $asText = false) // array('porro', 'sed', 'magni')

Solved it. The problem was the faker library. Apparently when you explicitly cast (string)$faker->whateverit fixes the problem.
解决了。问题是伪造的图书馆。显然，当你明确地投射(string)$faker->whatever它时，问题就解决了。
