将自定义 Netlify CMS 小部件添加到 Gatsby 入门 Yellowcake

Question

我正在使用 Gatsby 启动器“YellowCake”，其中包含 Netlify CMS。

我正在尝试将另一个自定义小部件添加到初学者联系页面。我想在“电话”下添加“传真”。我已将其添加到 config.yml 文件中，并将传真号码添加到我的contact.md 文件中，并将其添加到我的 ContactPage.js 模板中。但它没有显示在页面上。

我不确定我错过了什么或做错了什么。希望得到任何帮助。

Config.yml

collections: # A list of collections the CMS should be able to edit
  - name: 'pages'
    label: 'Page'
    delete: false # Prevent users from deleting documents in this collection
    editor:

    files:
      - file: 'content/pages/contact.md'
        label: 'Contact Page'

          - {
              label: Template,
              name: template,
              widget: hidden,
              default: ContactPage,
            }

Answer 1

您没有在 GraphQL 查询中获取 fax 字段：

export const pageQuery = graphql`
  query ContactPage($id: String!) {
    page: markdownRemark(id: { eq: $id }) {
      ...Meta
      html
      frontmatter {
        title
        template
        subtitle
        featuredImage
        address
        phone
        email
        fax # <-- here
        locations {
          mapLink
          lat
          lng
        }
      }
    }
  }
`

由于在 JSX 中 phone 下 fax 的解构和渲染，其余代码应该单独工作。

“无法在类型‘MarkdownRemarkFrontmatter’上查询字段‘传真’”

在运行gatsby clean 和在localhost:8000/___graphql 操场上测试您的查询。奇怪的是，您有一个名为 slug 的 hidden 字段（具有 contact 值）但您没有使用它。在您的情况下，我会使用页面查询，例如：

export const contactData = graphql`
    query getContactData {
        page: allMarkdownRemark(
            filter: { frontmatter: { slug: { eq: "contact" }}}) {
            edges {
                node {
                 ...Meta
                 html
                 frontmatter {
                   title
                   template
                   subtitle
                   featuredImage
                   address
                   phone
                   fax
                   email
                   locations {
                      mapLink
                      lat
                      lng
                     }
                  }
               }
            }
        }
    }
`;

然后是这样的：

const ContactPage = ({ data: { page: {
      edges: [{
        node: {
          html,
          frontmatter
        }
      }]
    }}}) => (
  <Layout
    meta={frontmatter.meta || false}
    title={frontmatter.title || false}
  >
    <ContactPageTemplate {...frontmatter} body={html} />
  </Layout>
)
