【问题描述】：

我想根据job_id: ID! 进行查询，但似乎我做错了什么，我想了解是什么。

所以我在这里接受工作 ID。

render() {
 const { job } = this.props.navigation.state.params;
 const job_id = job._id;
 ........
}

所以现在我想在这里使用job_id 进行查询

const GET_APPLICATIONS = gql`
  query getJobApplicationsForThisJob($job_id: ID!) {
    getJobApplicationsForThisJob(job_id: $job_id) {
      _id
    }
  }
`;

const DELETE_JOB = gql`
  mutation deteleJob($_id: ID!) {
      deleteJob(_id: $_id) {
        message
      }
    }
`;

const mutationConfig = {
    props: ({ mutate, ownProps }) => ({
        deleteJob: (_id) => mutate({ variables: { _id } }),
        ...ownProps,
    })
}

export default compose(
    withApollo,
    graphql(GET_APPLICATIONS, { name: "getApplications" }),
    graphql(DELETE_JOB, mutationConfig)
)(JobDetails);

但我最终得到以下错误

Invariant Violation: The operation 'getJobApplicationsForThisJob' wrapping 'JobDetails' is expecting variable 'job_id' but it was not found in the props passed to 'Apollo(JobDetails)'

有什么想法吗？

问题解决了。

我用过这样的 HOC

export default compose(
    withApollo,
    graphql(GET_APPLICATIONS, { name: "getApplications", options: (props) => ({ variables: { job_id: props.navigation.state.params.job._id } }) }),
    graphql(DELETE_JOB, mutationConfig)
)(JobDetails);
