将未嵌套的树规范化为使用 Normalizr 嵌套的树

Normalizing not nested tree into nested with Normalizr

本文关键字:嵌套 Normalizr 规范化      更新时间:2023-09-26

我必须规范化来自服务器的两个响应,并使用normalizr将它们存储在我的商店中。第一个回复给了我部分,第二个回复给了我帖子。部分有很多帖子一个帖子只能有一个部分

第一反应(部分):

[
  {
    id: 10,
    title: "foo"
  },
  ...
]

第二答复(员额):

[
  {
    id: 2,
    sid: 10, //id of the section
    title: "foo",
    text: "foo foo"
  },
  ...
]

我想将响应规范化到此架构中:

{
  entities: {
    sections: {
      10: {title: "foo", posts: [2, 5, 12, 152]},
      15: {title: "example", posts: [1, 8]},
      ...
    },
    posts: {
      1: {id: 1, sid: 15, title: "abc", text: "something"},
      2: {id: 2, sid: 10, title: "foo", text: "foo foo"},
      ...
    }
  }
}

由于响应不是嵌套的,我不知道如何定义架构。

也许你可以用简单的代码做到这一点?没有任何库?oO

var posts = [ ... ]; // some posts here
var sections = [ ... ]; // some sections here
var schema = { entities: { sections: {}, posts: {} } };
for (var i = 0; i < sections.length; i++) {
    var section = sections[i];
    schema.entities.sections[section.id] = {
        title: section.title,
        posts: []
    }
}
for (var j = 0; j < posts.length; j++) {
    var post = posts[j];
    schema.entities.posts[post.id] = post;
    schema.entities.sections[post.sid].posts.push(post.id);
}
