Laravel Lighthouse GraphQL 重命名关系突变

Question

我在更新与 graphQL 查询的重命名关系时遇到问题。

这是相关的架构和 Laravel 模型：

Laravel 型号

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Relations\BelongsTo;
use Illuminate\Database\Eloquent\Relations\BelongsToMany;

class Lead extends Model
{
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    // protected $fillable = [
    //     'lead_type_id',
    // ];

    protected $guarded = [];
    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        //
    ];

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        // 'created_at' => 'timestamp',
        // 'updated_at' => 'timestamp'
    ];

    /**
     * Get the LeadActions for the Lead.
     */
    public function leadActions()
    {
        return $this->hasMany(\App\Models\LeadAction::class);
    }

    /**
     * Get the clients for the Lead.
     */
    public function clients(): BelongsToMany
    {
        return $this->belongsToMany(Client::class);
    }

    /**
     * Get the LeadType for the Lead.
     */
    public function leadType(): BelongsTo
    {
        return $this->belongsTo(\App\Models\LeadType::class, 'lead_type_id');
    }
}

?>

<?php

namespace App\Models;

use App\Models;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Relations\HasMany;

class LeadType extends Model
{
    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name'
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        //
    ];

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'name' => 'string',
        'created_at' => 'timestamp',
        'updated_at' => 'timestamp'
    ];

    /**
     * Get the Leads for the LeadType.
     */
    public function leads(): HasMany
    {
        return $this->hasMany(Models\Lead::class);
    }

}
?>

GraphQl 架构

type Lead {
   id: ID!
   lead_type: LeadType @belongsTo(relation: "leadType")
   clients: [Client!]! @belongsToMany
   created_at: DateTime!
   updated_at: DateTime!
}
input UpdateLeadInput {
   id: ID!
   clients: UpdateClientsRelation
   lead_type: UpdateLeadTypeRelation
}
input UpdateLeadTypeRelation {
   create: CreateLeadTypeInput
   connect: ID
   update: UpdateLeadTypeInput
   upsert: UpsertLeadTypeInput
   delete: ID
   disconnect: ID
}

使用以下 graphQl 查询，我得到一个 SQL 错误，因为缺少列 lead_type：查询

mutation UpdateLead {
  updateLead(input: {id: 1, lead_type: {connect: 1}}) {
    id
    clients {
      id
      name
    }
    lead_type {
      id
      name
    }
  }
}

SQL错误

Column not found: 1054 Unknown column 'lead_type' in 'field list' (SQL: update `leads` set `lead_type` = {\"connect\":\"1\"}, `leads`.`updated_at` = 2020-01-14 17:11:17 where `id` = 1

我遵循了 Laravel 命名约定，并在线索 table 上将列命名为 lead_type_id。如果我删除 lead_type 关系到 leadType 的重命名，我可以成功运行更新突变，但我无法弄清楚如何让它使用正确的列名称（lead_type_id) 同时保持关系重命名。

非常感谢任何帮助。

非常感谢

您是否尝试过 @rename 指令？我的意思是你必须在 UpdateLeadInput 中的 lead_type 上使用它，因为灯塔寻找名为 lead_type 的关系，并且由于未定义，它假设 lead_type 是一个参数。

要么重命名模型中的关系，例如：

class Lead extends Model
{
    public function lead_actions()
    {
        return $this->hasMany(\App\Models\LeadAction::class);
    }

    public function lead_type(): BelongsTo
    {
        return $this->belongsTo(\App\Models\LeadType::class, 'lead_type_id');
    }
}

或

使用@rename指令（我没试过，但我的意思是它是这样工作的）：

input UpdateLeadInput {
   id: ID!
   clients: UpdateClientsRelation
   lead_type: UpdateLeadTypeRelation @rename(attribute: "leadType")
}
