为什么我在使用 php artisan tinker 时收到 Laravel 错误没有这样的表

Question

更新：正如有人在评论和答案中建议的那样，它有效。 但是当我在保存后尝试在末尾写入$profile->user时，它显示为空。 有人能猜出为什么吗？

我正在使用 Laravel 7。我不断收到错误Illuminate/Database/QueryException with message 'SQLSTATE[HY000]: General error: 1 no such table: profiles (SQL: insert into "profiles" ("title", "description", "user_id", "updated_at", "created_at") values (Cool Title, Description, 1, 2020-08-24 11:58:39, 2020-08-24 11:58:39))' ： Illuminate/Database/QueryException with message 'SQLSTATE[HY000]: General error: 1 no such table: profiles (SQL: insert into "profiles" ("title", "description", "user_id", "updated_at", "created_at") values (Cool Title, Description, 1, 2020-08-24 11:58:39, 2020-08-24 11:58:39))'

当我尝试使用这些命令时：

 php artisan tinker
Psy Shell v0.10.4 (PHP 7.4.9 — cli) by Justin Hileman
>>> $profile = new \App\Profile();
=> App\Profile {#3184}
>>> $profile->title='Cool Title';
=> "Cool Title"
>>> $profile->description='Description';
=> "Description"
>>> $profile->user_id = 1;
=> 1
>>> $profile->save();

保存后，我收到该错误。

如果需要更多代码，请告诉我我会更新我的问题。 这是我在开始时提到的唯一错误。

Answer 1

我不知道您是否在数据库中创建了user_profiles表，但您可以在 tinker 中执行以下操作：

$profile = new \App\UserProfiles();

如果模型已经创建

Answer 2

您必须迁移表（如果您还没有创建表，让我们创建一个。）：

php artisan migrate

重复你的代码后：

$profile = new \App\Profile();

$profile->title='Cool Title';

$profile->description='Description';

$profile->user_id = 1;

$profile->save();

如果您使用 Laravel 8，请使用：

    $profile = new App\Models\Profile();
