类型为 "image"的 GraphQL 错误字段 "File"必须选择子字段。你的意思是 "image { ... }"吗？

Question

我正在使用 gatsby 和 Netlify CMS 构建一个站点。我使用了 Gatsby Site Starter。

我不断收到"file"类型的“GraphQL 错误字段”图像，必须选择子字段。您的意思是“图像 { ... }”吗？尝试部署到 Netlify 时出错。一切都在本地主机上完美运行，但图像似乎有些失败。我查看了 Netlify CMS 页面上提供的示例，发现有人具有完全相同的设置，一个列表小部件(充当画廊)，其中包含图像和描述，here .

配置文件

backend:
  name: git-gateway
  repo: grantballmer/gatsby-starter-netlify-cms
  branch: master

media_folder: static/img
public_folder: /img

collections:

  - name: "gallery"
    label: "Gallery"
    folder: "src/pages/services"
    create: true
    fields: 
      - { label: "Template Key", name: "templateKey", widget: "hidden", default: "gallery" }
      - {label: "Title", name: "title", widget: "string"}
      - label: "Grid"
        name: "grid"
        widget: "list"
        fields: 
          - {label: "Image", name: "image", widget: "image"}
          - {label: "Band Name", name: "band", widget: "string"}`

Gallery.js(模板文件)

import React from 'react';
import { graphql } from 'gatsby';
import Layout from "../components/Layout";
import PhotoGrid from "../components/services/PhotoGrid";

const GalleryTemplate = ({ data }) => {
  const { markdownRemark: gallery } = data;
  const images = gallery.frontmatter.grid;

  return (
    <Layout>
      <PhotoGrid images={images} />
    </Layout>
  );
};

export default GalleryTemplate;

export const galleryQuery = graphql `
  query Gallery($id: String!) {
    markdownRemark(id: { eq: $id }) {
      html
      frontmatter {
        title
        grid {
          image 
          band
        }
      }
    }
  }
`;

我没有使用过 Netlify CMS，但看起来您的 Image 可能是一个带有子字段的集合(例如: image { source, id .. } ，在这种情况下，您应该像这样重写查询:

export const galleryQuery = graphql `
  query Gallery($id: String!) {
    markdownRemark(id: { eq: $id }) {
      html
      frontmatter {
        title
        grid {
          image { 
             id
             source
             ..
          }
          band
        }
      }
    }
  }
`;
