如何使用NetlifyCMS和Gatsby将子弹显示在graphql中？

Question

在站点上添加netlify cms时，如何将子弹显示在graphql中？我有一个博客文章集，除了子弹外，所有内容都显示出来：

backend:
  name: git-gateway
  branch: master # Branch to update (optional; defaults to master)

media_folder: static/images
public_folder: /images

collections:
  - name: "blog"
  label: "Blog"
  folder: "content/blogPost"
  create: true
  slug: "{{year}}-{{month}}-{{day}}-{{slug}}"
  fields: # The fields for each document, usually in front matter
    - { label: "Layout", name: "layout", widget: "hidden", default: "blog" }
    - { label: "Title", name: "title", widget: "string" }
    - { label: "Publish Date", name: "date", widget: "datetime" }
    - { label: "Featured Image", name: "thumbnail", widget: "image" }
    - { label: "Body", name: "body", widget: "markdown" }

这是我的graphql查询：

将slug在GraphQL查询是不是在该领域的frontmatter的一部分config.yml。这些段字段无关。您在查询中指的是Gatsby中的节点。

fields您的中缺少上述GraphQL查询中的值node。如下例所示，必须通过gatsby-node.js添加配置来使用它：

const { createFilePath } = require('gatsby-source-filesystem')

exports.onCreateNode = ({ node, boundActionCreators, getNode }) => {
  const { createNodeField } = boundActionCreators

  if (node.internal.type === `MarkdownRemark`) {
    const value = createFilePath({ node, getNode })
    createNodeField({
      name: `slug`,
      node,
      value,
    })
  }
}
