php - 如何解决 APIATO 项目中的完整性约束违规错误？

Question

我在里面开发了一个 APIATO 项目，我想执行 CRUD 操作，为此我创建了一个名为 upload 的函数，该函数负责发布详细信息，并通过将凭据传递给 .env 文件与我的数据库集成，当我尝试在邮递员中发送请求时我收到以下错误

Illuminate\Database\QueryException: SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'name' cannot be null (SQL: insert into `blogs_table` (`name`, `price`, `image`, `rating`, `country`, `description`, `user_id`, `updated_at`, `created_at`) values (?, ?, ?, ?, ?, ?, ?, 2021-08-08 17:06:53, 2021-08-08 17:06:53)) in file /home/vagrant/code/apiato/vendor/laravel/framework/src/Illuminate/Database/Connection.php on line 692

我没有得到如何解决此错误，请帮助我解决此问题...

Answer 1

您$request->input('name')在 BlogContoller.php 中为空。您可以nullable()在迁移中为name列添加方法，如下所示。

$table->string('name')->nullable();
