通过Netlify CMS创建时帖子未更新

Question

我已经通过Netlify CMS创建了一个新帖子，但是这些帖子并没有在Gatsby网站上更新。我已经完全按照add Netlify CMS to existing sites文档进行了操作，但似乎所有工作都很好，只是该帖子未显示在我的网站上。

以下是带有回购和config.yml文件的指向我网站的链接：

我的网站：https://my-blogger.netlify.app/

我的仓库：https://github.com/mohammedasker/blogger

config.yml

backend:
  name: git-gateway
  branch: master

media_folder: "static/media"
public_folder: "/media"

collections:
  - name: "blog"
    label: "Blog"
    folder: "src/content"
    create: true
    slug: "{{year}}-{{month}}-{{day}}-{{slug}}"
    fields:
      - { label: "Layout", name: "layout", widget: "hidden", default: "blog" }
      - { label: "Title", name: "title", widget: "string" }
      - { label: "Slug", name: "slug", widget: "string" }
      - { label: "Draft", name: "draft", widget: "boolean", default: true }
      - { label: "Description", name: "description", widget: "text" }
      - { label: "Publish Date", name: "date", widget: "datetime" }
      - { label: "Body", name: "body", widget: "markdown" }

其他信息 我在部署详细信息中注意到，“ gatsby-node.js”中的path值为null，这可能会阻止更新该帖子。话虽这么说，当部署全部为绿色时，问题仍然存在。

已更新：添加了“ gatsby-node.js”文件

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

exports.onCreateNode = ({ node, getNode, actions }) => {
  const { createNodeField } = actions
  if (node.internal.type === `MarkdownRemark`) {
    const slug = createFilePath({ node, getNode, basePath: `pages` })
    createNodeField({
      node,
      name: `slug`,
      value: slug,
    })
  }
}

exports.createPages = ({ graphql, actions }) => {
  const { createPage } = actions
  const blogPostTemplate = path.resolve(`src/templates/blog-post.js`)
  return graphql(`
    {
      allMarkdownRemark {
        edges {
          node {
            frontmatter {

      }
    }
  `).then(result => {
    if (result.errors) {
      return Promise.reject(result.errors)
    }
    result.data.allMarkdownRemark.edges
      .filter(({ node }) => !node.frontmatter.draft)
      .forEach(({ node }) => {
        createPage({
          path: node.frontmatter.path,

由于Gatsby是静态站点生成器，因此您必须重新构建以更新内容。 仅在构建后，您才能检查更新，因为在构建时Gatsby会从Netlify CMS中获取更新的数据。

但是您可以使用Netlify CMS实施实时更新，您需要添加降价页面。
