从内容数据以编程方式创建 Gatsby 页面 [英] Programmatically create Gatsby pages from Contentful data

问题描述

我正在寻求有关 GatsbyJS 和 Contentful 的帮助.文档没有给我足够的信息.

I am looking for help with GatsbyJS and Contentful. The docs aren't quite giving me enough info.

我希望基于内容丰富的数据以编程方式创建页面.在这种情况下，数据类型是零售商店"，在/retail_store_name

I am looking to programmatically create pages based on contentful data. In this case, the data type is a retail "Store" with a gatsby page at /retail_store_name

每个商店的 index.js 基本上是几个 react 组件，其中传递了 props，例如商店名称和谷歌地点 ID.

The index.js for each store is basically a couple of react components with props passed in e.g. shop name and google place ID.

1. 向内容添加数据.这是我的示例数据模型:

1. Add data to contentful. Here is my example data model:

{
    "name": "Store"
    "displayField": "shopName",
    "fields": [
        {
            "id": "shopName",
            "name": "Shop Name",
            "type": "Symbol",
            "localized": false,
            "required": true,
            "validations": [
                {
                "unique": true
                }
            ],
            "disabled": false,
            "omitted": false
            },
            {
            "id": "placeId",
            "name": "Place ID",
            "type": "Symbol",
            "localized": false,
            "required": true,
            "validations": [
                {
                "unique": true
                }
            ],
            "disabled": false,
            "omitted": false
        }
}

我已将内容丰富的站点数据添加到 gatsby-config.js

I've added the contentful site data to gatsby-config.js

// In gatsby-config.js
plugins: [
    {
        resolve: `gatsby-source-contentful`,
        options: {
        spaceId: `your_space_id`,
        accessToken: `your_access_token`
        },
    },
];

查询内容丰富 - 我不确定这应该发生在哪里.我有一个模板文件，它可以作为根据内容数据创建的每个商店网页的模型.

Query contentful - I'm not sure where this should happen. I've got a template file that would be the model for each store webpage created from contentful data.

如前所述，这只是一些传入 props 的组件.示例:

As mentioned this is just some components with props passed in. Example:

import React, { Component } from "react";

export default class IndexPage extends Component {
constructor(props) {
    super(props);
    this.state = {
        placeId: "",
        shopName: "",
    };
}
render (){
    return (
        <ComponentExampleOne shopName={this.state.shopName} />
        <ComponentExampleTwo placeId={this.state.placeId} />
    );
}

我真的不知道该怎么做.最终目标是为非技术用户自动发布，他们在 Contentful 中发布新商店以在生产站点上进行更新.

I'm really not sure how to go about this. The end goal is auto publishing for non-tech users, who post new stores in Contentful to be updated on the production site.

推荐答案

您可以在构建时动态创建页面，为此您需要向 gatsby-node.js 文件添加一些逻辑.这是一个简单的片段.

You can create pages dynamically at build time and to do that you need to add some logic to the gatsby-node.js file. Here is a simple snippet.

const path = require('path')

exports.createPages = ({graphql, boundActionCreators}) => {
  const {createPage} = boundActionCreators
  return new Promise((resolve, reject) => {
    const storeTemplate = path.resolve('src/templates/store.js')
    resolve(
      graphql(`
        {
          allContentfulStore (limit:100) {
            edges {
              node {
                id
                name
                slug
              }
            }
          }
        }
      `).then((result) => {
        if (result.errors) {
          reject(result.errors)
        }
        result.data.allContentfulStore.edges.forEach((edge) => {
          createPage ({
            path: edge.node.slug,
            component: storeTemplate,
            context: {
              slug: edge.node.slug
            }
          })
        })
        return
      })
    )
  })
}

导出的 createPages 是 Gatsby Node API 函数，您可以在文档 这里.

the createPages that was exported is a Gatsby Node API function you can find the complete list in the docs here.

对于查询 allContentfulStore 是这样调用的，因为您的 contentType 名称是 store，gatsby 查询将是 allContentful{ContentTypeName}.

For the query allContentfulStore it's called like that because your contentType name is store the gatsby query will be allContentful{ContentTypeName}.

最后，我创建了一个 YouTube 视频系列，解释了如何使用 Contentful 构建 Gatsby 网站.您可以在此处

Finally, I created a youtube video series explaining how you can build a Gatsby website with Contentful. You can find it here

我希望这能回答你的问题.干杯，哈立德
