我有这个GraphQL查询:
mutation CreateBudget(
$revenue: Float!,
$hours: Int!,
$projectId: Int!,
) {
createBudget(
revenue: $revenue,
hours: $hours,
projectId: $projectId,
) {
id
}
}
对于最佳实践,我想在这里使用camelcase,但是在我的数据库中使用snake_case。该表如下所示:
CREATE TABLE IF NOT EXISTS `budgets` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`revenue` double(8,2) NOT NULL,
`hours` int(11) NOT NULL,
`project_id` int(10) unsigned NOT NULL,
`created_at` timestamp NULL DEFAULT NULL,
`updated_at` timestamp NULL DEFAULT NULL,
PRIMARY KEY (`id`),
KEY `budgets_project_id_foreign` (`project_id`),
CONSTRAINT `budgets_project_id_foreign` FOREIGN KEY (`project_id`) REFERENCES `projects` (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_unicode_ci;
我使用Lighthouse's @rename directive以便在大小写之间进行转换。但是,在运行查询时,在提交查询时,代码的某些部分似乎无法识别项目ID,从而导致以下SQL错误:
SQLSTATE[HY000]: General error: 1364 Field 'project_id' doesn't have a default value (SQL: insert into `budgets` (`revenue`, `hours`, `updated_at`, `created_at`) values (1200, 12, 2019-12-03 09:12:13, 2019-12-03 09:12:13))
发送的变量是
variables: {
revenue: 1200,
hours: 12,
projectId: 1
}
这是我的schema.graphql的外观,使用Budget类型的@rename指令:
type Budget {
id: ID!
revenue: Float!
hours: Int!
projectId: Int! @rename(attribute: "project_id")
project: Project! @belongsTo
created_at: DateTime
updated_at: DateTime
}
type Mutation {
createBudget(
revenue: Float!
hours: Int!
projectId: Int!
): Budget @create(model: "App\\Models\\Budget\\Budget")
}
我一定忽略了一些简单的事情,但似乎无法发现它。有人要试一试吗?

从4.7版开始支持在突变上使用重命名指令,并且需要在突变中的属性上额外声明重命名指令。
您的突变应如下所示:
type Mutation {
createBudget(
revenue: Float!
hours: Int!
projectId: Int! @rename(attribute: "project_id")
): Budget @create(model: "App\\Models\\Budget\\Budget")
}
