Question

我正在尝试使用GraphQL查询带有Gridsome中对象的非结构化数组。当前看起来非常混乱，感觉应该有更好的方法来实现这一点。

从CMS加载到GraphQL中的数据如下所示：

{
    title: "Homepage",
    top_image: "imgurl.jpg",
    page_builder: [
             {
                 type: "slider",
                 field: "data example",
                 different_field: "data example"
             },
              {
                 type: "call_to_action",
                 field_for_cta: "data example",
                 different_cta_field: "data example"
             }
    ]
}

如您所见，page_builder中的对象将具有不同的字段，具体取决于客户端如何构建此部分。

当我尝试在GraphQL中查询它时。它将变得非常混乱：

<page-query>
query {
  data: pages(path: "/pages") {
    title,
    top_image,
    page_builder {
      type,
      field,
      different_field,
      type,
      field_for_cta,
      different_cta_field

      #this list will have way more fields depending on all the page builder elements

    }
    }
  }
</page-query>

有没有一种方法可以按类型组织此字段，并且只返回此特定类型的字段？

假设gridsome支持片段，则可以执行以下操作：

<page-query>
query {
  data: pages(path: "/pages") {
    title,
    top_image,
    page_builder {
      ...A @include(if: $includeA)
      ...B @include(if: $includeB)
      ...C @include(if: $includeC)
    }
  }
}

# Note: Replace PageBuilderType with appropriate type
fragment A on PageBuilderType {
  # your fields here
}
fragment B on PageBuilderType {
  # your fields here
}
fragment C on PageBuilderType {
  # your fields here
}
</page-query>

然后您可以在调用createPage时定义变量，如here所示：

api.createPages(({ createPage }) => {
    createPage({
      path: '/my-page',
      component: './src/templates/MyPage.vue',
      queryVariables: {
        includeA: someCondition,
        includeB: someCondition,
        includeC: someCondition,
      },
    })
  })
}
