Resolve alias field

[zabaala]

Hi

I'm trying to create somes types and a case sound strange for me. When I try to create a field with a custom name, and I set the correct field name in alias, the aliased value field value is not returned.

The value is returned only if implement resolveCustomFieldResolve() method. It's correct?

Thanks.

This is my UserType.php with a custom field called images:

return [
    'idUser' => [
        'type' => Type::nonNull(Type::int()),
        'description' => 'User identification, primary key'
    ],
    'images' => [
        'type' => GraphQL::paginate('ImageType'),
        'description' => 'Images create by the user',
        'args' => $pagination
    ],
]

protected function resolveImagesField($root, $args)
{
    $images = $root->images(); 
    return $images->paginate($args['limit'], ['*'], 'page', $args['page']);
}

Thanks, @albertcito.

In my case is different. I want understand because the alias is not resolved automatically.

BTW you are passing $pagination to args, to receive him in resolveImagesField($root, $args) method. What does $pagination do? And where i can find all attributes that can be passed to a field (like as: type, description, args, alias, ...others)?

Please elaborate your issue or show an example

@rebing,

Let's say i creating a Customer Type from a model that has a attribute called address_number. Then we would have something similar to this:

<?php

class Subscriber extends Type
{
  // ...
  public function fields()
  {
    'addressNumber' => [
      'type' => Type::int(),
      'alias' => 'address_number'
     ]
  }
}

In that case, if I do not implement the resolveAddressNumberResolve() method, the address_number value will not be returned, although the field is being queried in the database. My question is: should not this / could happen automatically, since I am informing the alias?

This ends up generating unnecessary code. Implementing this method would be interesting in cases such as the email field mentioned in the example of the repository itself, where the field needs to be returned in the low case.

Same issue as #130 if i understand correctly your problem

<?php

class Subscriber extends Type
{
  // ...
  public function fields()
  {
    'addressNumber' => [
      'type' => Type::int(),
      'alias' => 'address_number',
      'resolve' => function ($root) { // As a workaround
               return $root->address_number;
      }
     ]
  }
}

@anolek exactly!

My question is: because alias is not resolved automatically as mentioned by @rebing here?

Follow a piece of his comment:

To be honest, I don't think I've ever used the alias field myself, but that doesn't look like the correct behavior. It should be as you said that it automatically resolves to the correct field. So if the alias is end_period_number, then it should resolve to $root->end_period_number automatically.

@zabaala As I mentioned in the other thread, you can look into it and find the problem in SelectFields class.

@zabaala I believe this was fixed with #283 , can you try the v1.22.0 release?

[anolek]

After upgrading to v1.22.0, it is, indeed fixed @mfn

[zabaala]

I'll try it soon, @mfn.

Thanks.

[dharkness]

Aliases work for me as well with v1.22.0.

There has been now feedback from OP but given the other feedback and the PR I merged, I'm pretty sure this is fixed.

If not, please simply create a new issue => thanks!
