Laravel Lighthouse GraphQL renamed relationship mutation - php

Question

I'm having an issue updating a renamed relationship with a graphQL query.
Here's the related schema and Laravel models:
Laravel Models
<?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 Schema
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
}
Using the following graphQl query I get an SQL error for missing column lead_type:
Query
mutation UpdateLead {
updateLead(input: {id: 1, lead_type: {connect: 1}}) {
id
clients {
id
name
}
lead_type {
id
name
}
}
}
SQL Error
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
I've followed the Laravel naming convention, and named the column lead_type_id on the leads table. If I remove the renaming of the lead_type relationship to leadType I can successfully run an update mutation, but I can't figure out how to get it to use the correct name for the column (lead_type_id) whilst keeping the relationship renamed.
Any help is greatly appreciated.
Many Thanks

Answer 1

Have you tried #rename directive? I mean you have to use it on lead_type in your UpdateLeadInput, because lighthouse looks for relation named lead_type, and as this is not defined, it assume that lead_type is an argument.
Either rename your relations in models, like:
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');
}
}
OR
use #rename directive (I didn't try it, but I mean it works like this):
input UpdateLeadInput {
id: ID!
clients: UpdateClientsRelation
lead_type: UpdateLeadTypeRelation #rename(attribute: "leadType")
}
