Loopback 4: Exclude issue in hasone relations

Nobody has claimed this yet.

Hello all,

I have looked for a solution to that, but I see nothing in the documentation and in the forums. I start to think that it is not possible to do, or that it is some kind of issue.

In a schema, It is possible to exclude a field how comes from a @hasone relation?


I have tried several things. The more weird is that if in the exclude you indicate a property who appears in the model A and in the hasOne relation model, in the schema, for both models, the property is excluded. :

```
@patch('/user/{id}', {
responses: {
'204': {
description: 'Update all the information related with the user',
},
},
})
@authenticate('jwt', { required: [PermissionKey.UpdateOwnUser] })
async updateById(
@param.path.string('id') id: string,
@requestBody({
content: {
'application/json': {
schema: getModelSchemaRef(UserFeatures, {
includeRelations: true,
exclude: ['idUser', 'stripeCustomerId', 'userIAM.permissions'],
}),

},
},
})
```
The problem is that the exclude doesnt´work for the hasOne relation: exclude: ['idUser', 'stripeCustomerId'] --> OK exclude: ['permissions'] --> Fails

Any idea of how to exclude a field of the "hasOne Relation model"?

Thanks in advance

Start at getModelSchemaRef and the @requestBody schema shown in the issue, focusing on how includeRelations and exclude are interpreted for hasOne relations. Reproduce the example with exclude: ['permissions']; done means the nested relation field is excluded without changing the existing top-level exclusions.
