[英]Laravel LightHouse GraphQL DateTime Input in Mutation Is Always Null
我正在學習 Laravel 和 LightHouse,我正在嘗試創建一個使用 DateTime 並將其放入數據庫的突變。 每次我通過 DateTime 進行突變時,輸入都不會顯示,並且只是標記為空,在數據庫中觸發錯誤,因為該表不允許 DateTime 為空。 我所有的其他值都工作得很好,所以我很困惑。 GraphQL Playground 拋出的錯誤是SQLSTATE[23502]: Not null violation: 7 ERROR: null value in column \\"date_of_birth\\" violates not-null constraint\\nDETAIL: Failing row contains (17, Blaze, blaze@test.com, null, ABadPassword, null, 2020-08-26 19:54:38, 2020-08-26 19:54:38, null). (SQL: insert into \\"users\\" (\\"username\\", \\"password\\", \\"email\\", \\"updated_at\\", \\"created_at\\") values (Blaze, ABadPassword, blaze@test.com, 2020-08-26 19:54:38, 2020-08-26 19:54:38) returning \\"id\\")"
SQLSTATE[23502]: Not null violation: 7 ERROR: null value in column \\"date_of_birth\\" violates not-null constraint\\nDETAIL: Failing row contains (17, Blaze, blaze@test.com, null, ABadPassword, null, 2020-08-26 19:54:38, 2020-08-26 19:54:38, null). (SQL: insert into \\"users\\" (\\"username\\", \\"password\\", \\"email\\", \\"updated_at\\", \\"created_at\\") values (Blaze, ABadPassword, blaze@test.com, 2020-08-26 19:54:38, 2020-08-26 19:54:38) returning \\"id\\")"
在 GraphQL Playground 中嘗試的這個 Mutation:
mutation {
createUser(
username: "Blaze"
email: "blaze@test.com"
password: "ABadPassword"
date_of_birth: "1998-01-16 00:00:00"
){
id
}
}
這是我的架構:
"A date string with format `Y-m-d`, e.g. `2011-05-23`."
scalar Date @scalar(class: "Nuwave\\Lighthouse\\Schema\\Types\\Scalars\\Date")
"A datetime string with format `Y-m-d H:i:s`, e.g. `2018-05-23 13:43:32`."
scalar DateTime @scalar(class: "Nuwave\\Lighthouse\\Schema\\Types\\Scalars\\DateTime")
type Mutation {
createUser(
username: String @rules(apply: ["required", "unique:users,username"]),
password: String @rules(apply: ["required"]),
email: String @rules(apply: ["required", "unique:users,email"]),
date_of_birth: DateTime @rules(apply: ["required"])
): User! @create
}
type User {
id: ID!
username: String!
email: String!
email_verified_at: DateTime
password: String!
created_at: DateTime!
updated_at: DateTime!
date_of_birth: DateTime!
}
這是應用程序中 User.php 文件中的我的用戶:
<?php
namespace App;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Illuminate\Notifications\Notifiable;
class User extends Authenticatable
{
use Notifiable;
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [
'username', 'email', 'password',
'date_of_birth' => 'datetime'
];
/**
* The attributes that should be hidden for arrays.
*
* @var array
*/
protected $hidden = [
'password', 'remember_token',
];
/**
* The attributes that should be cast to native types.
*
* @var array
*/
protected $casts = [
'email_verified_at' => 'datetime',
];
}
這是我在數據庫中由遷移創建的表:
DatabaseName=# SELECT * FROM users;
id | username | email | email_verified_at | password | remember_token | created_at | updated_at|
date_of_birth
希望這為錯誤提供了足夠的上下文,並提前感謝您的幫助。
我認為您的問題在於您如何聲明模型的$fillable
。 您添加一個條目索引'date_of_birth'
和值'datetime'
這將使 Laravel 認為可填充值是datetime
改成這個
/**
* The attributes that are mass assignable.
*
* @var array
*/
protected $fillable = [
'username', 'email', 'password', 'date_of_birth',
];
