Laravel遷移失敗，但查詢無效

我有一個無法運行的遷移。Laravel遷移失敗，但查詢無效

public function up() 
{ 
    Schema::create('users_watch_history', function (Blueprint $table) { 
     $table->string('id', 36)->primary(); 
     $table->string('user_id', 36); 
     $table->string('video_id', 36); 
     $table->string('course_id', 36); 
     $table->timestamp('last_timestamp'); 
     $table->float('vid_watch', 5, 2); 
     $table->float('total_watch', 5, 2); 
     $table->text('watched_parts'); 
     $table->integer('last_position'); 
     $table->softDeletes(); 

     $table->foreign('user_id') 
      ->references('id')->on('users') 
      ->onDelete('cascade')->onUpdate('cascade'); 

     $table->foreign('video_id') 
      ->references('id')->on('videos') 
      ->onDelete('cascade')->onUpdate('cascade'); 

     $table->foreign('course_id') 
      ->references('id')->on('courses') 
      ->onDelete('cascade')->onUpdate('cascade'); 
    }); 
}

當遷移實際上是跑我不斷收到有關的last_timestamp列無效的默認值的錯誤消息。

$ php artisan migrate 


    [Illuminate\Database\QueryException] 
    SQLSTATE[42000]: Syntax error or access violation: 1067 Invalid 
    default value for 'last_timestamp' (SQL: create table 
    `users_watch_history` (`id` varchar(36) not null, `user_id` 
    varchar(36) not null, `video_id` varchar(36) not null, `course_id` 
    varchar(36) not null, `last_timestamp` timestamp not null, 
    `vid_watch` double(5, 2) not null, `total_watch` double(5, 2) not 
    null, `watched_parts` text not null, `last_position` int not null, 
    `deleted_at` timestamp null) default character set utf8 collate utf8_unicode_ci) 



    [PDOException] 
    SQLSTATE[42000]: Syntax error or access violation: 1067 Invalid default value for 'last_timestamp'

我的MySQL版本

> select @@version 
+------------+ 
| @@version | 
+------------+ 
| 5.6.34-log | 
+------------+ 
1 row in set (0.20 sec)

但是，這扔我的曲線是扭曲 - 如果我運行在CLI創建命令爲DB，一切工作正常？

> create table `users_watch_history` (`id` varchar(36) not null, `user_id` varchar(36) not null, `video_id` varchar(36) not null, `course_id` varchar(36) not null, `last_timestamp` timestamp not null, `vid_watch` double(5, 2) not null, `total_watch` double(5, 2) not null, `watched_parts` text not null, `last_position` int not null, `deleted_at` timestamp null) default character set utf8 collate utf8_unicode_ci; 
Query OK, 0 rows affected (0.19 sec)

表模式：

> show create table users_watch_history \G 
*************************** 1. row *************************** 
     Table: users_watch_history 
Create Table: CREATE TABLE `users_watch_history` (
    `id` varchar(36) COLLATE utf8_unicode_ci NOT NULL, 
    `user_id` varchar(36) COLLATE utf8_unicode_ci NOT NULL, 
    `video_id` varchar(36) COLLATE utf8_unicode_ci NOT NULL, 
    `course_id` varchar(36) COLLATE utf8_unicode_ci NOT NULL, 
    `last_timestamp` timestamp NOT NULL, 
    `vid_watch` double(5,2) NOT NULL, 
    `total_watch` double(5,2) NOT NULL, 
    `watched_parts` text COLLATE utf8_unicode_ci NOT NULL, 
    `last_position` int(11) NOT NULL, 
    `deleted_at` timestamp NULL DEFAULT NULL 
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci 
1 row in set (0.17 sec)

任何想法，這可能是造成這種有效的查詢不通過遷移運行？

檢查你的'explicit_defaults_for_timestamp' MySQL變量。控制檯和項目之間的區別可能在於不同的環境（對於該變量具有不同的值）。 https://dev.mysql.com/doc/refman/5.7/en/server-system-variables.html#sysvar_explicit_defaults_for_timestamp – Axalix

禁用MySQL嚴格模式。

在你laravel配置文件database.php，設置 'strict' => true 爲' strict' => false
或添加nullable()到 $table->timestamp('last_timestamp')->nullable();

其中一個的應該解決的問題。
