我跟着@JellyBool的视频学习。
在CMD命令行上运行了下面的命令。
php artisan make:migration create_articles_table --create=articles
然后在 2015_10_23_022143_create_articles_table.php 中书写了下面的代码
public function up() { Schema::create('articles', function (Blueprint $table) { $table->increments('id'); $table->string('title'); $table->text('content'); $table->timestamps('published_at'); $table->timestamps(); }); }
接着在CMD上运行就弹出错误了,数据库里也没有显示articles
表,是哪个地方出现了字段重复?

好吧 终于发现了 是我的疏忽大意
$table->timestamps('published_at'); 应该改为 $table->timestamp('published_at');
timestamps()与timestamp()不同。前者是一个 Laravel 用来管理创建和修改作为created_at和updated_at TIMESTAMP列的方法。所以跟下面的方法重复了,导致出现字段重复的问题
楼主,我执行php artisan migrate
的时候就失败,你怎么可以执行成功
[PDOException]
SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using pas
sword: YES)
我用的5.1版本.evn文件修改如下:
DB_HOST=127.0.0.1
DB_DATABASE=homestead
DB_USERNAME=root
DB_PASSWORD=secret
执行上面呢句就报错
