Issue "Grammar::parameterize() must be of the type array" while try to run a seed class
提问by ReynierPM
I have the following seeder class in Laravel 5.3.x (latest):
我在 Laravel 5.3.x（最新）中有以下播种机类：
public function run()
{
$faker = Faker::create();
$bands = \App\Band::all()->pluck('id')->toArray();
for ($i = 1; $i < 100; $i++) {
\App\Album::create([
'band_id' => $faker->randomElements($bands),
'name' => $faker->name,
'recorded_date' => $faker->date(),
'release_date' => $faker->date(),
'number_of_tracks' => $faker->randomNumber(5),
'label' => $faker->sentence(3),
'producer' => $faker->company,
'genre' => $faker->randomElements([
'Art Punk',
'Alternative Rock',
'College Rock',
'Experimental Rock',
'Folk Punk',
'Goth / Gothic Rock',
'Grunge',
'Hardcore Punk'
], 1)
]);
}
}
Each time I try to run the seed I got the following error:
每次我尝试运行种子时，都会出现以下错误：
[Symfony\Component\Debug\Exception\FatalThrowableError]
Type error: Argument 1 passed to Illuminate\Database\Grammar::parameterize() must be of the type array, string given, called in /data/www/vendor/laravel/framework/src/Illuminate/Database/Query/Grammars/Grammar.php on line 665

Why?
为什么？

Change $faker-randomElements()to $faker->randomElement(). band_idis expecting an integer and given an array. genreis expecting a string and given an array.
更改$faker-randomElements()为$faker->randomElement()。band_id期待一个整数并给出一个数组。genre期待一个字符串并给出一个数组。
