在创建模型的GraphQL/Relay变异中,有没有办法获取模型ID？

Question

我们在一个新项目中使用Relay和GraphQL.

我们有一个Relay突变,它在DB中创建了一个新模型:

export default class AddCampaignMutation extends Relay.Mutation {
    getMutation() {
        return Relay.QL`mutation { addCampaign }`;
    }
    getVariables() {
        return {
            type: this.props.campaignType
        };
    }
    getFatQuery() {
        return Relay.QL`
            fragment on AddCampaignPayload {
                campaignEdge
                viewer
            }
        `;
    }
    getConfigs() {
        return [{
            type: 'RANGE_ADD',
            parentName: 'viewer',
            parentID: this.props.viewer.id,
            connectionName: 'campaigns',
            edgeName: 'campaignEdge',
            rangeBehaviors: {
              '': 'append',
            },
        }];
    }
    static fragments = {
        viewer: () => Relay.QL`
            fragment on User {
                id
            }
        `,
    };
}

但是,由于没有任何组件当前正在查询RANGE_ADD(viewer { campaigns })中指定的范围,因此Relay会智能地从该查询中排除该查询AddCampaignPayload.

这会导致控制台警告:

Warning: writeRelayUpdatePayload(): Expected response payload to include the newly created edge `campaignEdge` and its `node` field. Did you forget to update the `RANGE_ADD` mutation config?

我真的想要取回新创建的模型的ID,以便我可以将客户端导航到它.例如,回到新的campaignEdge,我想发送客户端/campaigns/${campaignEdge.node.id}.

有没有办法告诉Relay获取该优势？我是否正确配置了此突变？

您可以REQUIRED_CHILDREN在此上下文中使用.有关更多详细信息,请参阅https://github.com/facebook/relay/issues/237和https://github.com/facebook/relay/issues/236.

REQUIRED_CHILDREN 允许您为此模式指定额外的数据依赖项.
