我正在尝试将我的应用程序切换为使用 Uuid,但我的迁移在事件表上失败。
SQLSTATE[42000]:语法错误或访问冲突:1068 定义了多个主键(SQL:更改表
添加主键events
(events_id_primary
))id
Schema::create('events', function (Blueprint $table) {
$table->uuid('id')->primary();
$table->string('title', 255);
$table->integer('join_id', 6)->unique();
$table->string('image')->nullable();
$table->string('location')->nullable();
$table->text('description')->nullable();
$table->timestamp('event_date')->nullable();
$table->timestamp('event_time')->nullable();
$table->foreignUuid('user_id')->nullable()->index();
$table->foreign('user_id')
->references('id')
->on('users')
->onDelete('cascade');
$table->softDeletes();
$table->timestamps();
});
Schema::create('users', function (Blueprint $table) {
$table->uuid('id')->primary();
$table->string('name')->nullable();
$table->string('email')->unique();
$table->string('username')->nullable();
$table->string('avatar')->nullable();
$table->string('phone_number')->nullable();
$table->timestamp('email_verified_at')->nullable();
$table->string('password');
$table->rememberToken();
$table->timestamps();
});
非常感谢任何帮助!
当您检查
integer()
的文档时,您会发现第二个参数不是用于大小,而是用于字段的自动增量/主字段。整数类型本身就是一个大小(tinyInteger、smallInteger、bigInteger,...)。 6
转换为布尔值返回 true。
/**
* Create a new integer (4-byte) column on the table.
*
* @param string $column
* @param bool $autoIncrement
* @param bool $unsigned
* @return \Illuminate\Database\Schema\ColumnDefinition
*/
public function integer($column, $autoIncrement = false, $unsigned = false)
{
return $this->addColumn('integer', $column, compact('autoIncrement', 'unsigned'));
}
你只需要删除那个6
Schema::create('events', function (Blueprint $table) {
$table->uuid('id')->primary();
$table->string('title', 255);
$table->integer('join_id')->unique();
$table->string('image')->nullable();
$table->string('location')->nullable();
$table->text('description')->nullable();
$table->timestamp('event_date')->nullable();
$table->timestamp('event_time')->nullable();
$table->foreignUuid('user_id')->nullable()->index();
$table->foreign('user_id')
->references('id')
->on('users')
->onDelete('cascade');
$table->softDeletes();
$table->timestamps();
});
