我在做Redis还是什么？-DEV365 开发者社区

首先，让我们从错误开始。

node:internal/process/esm_loader:94
    internalBinding('errors').triggerUncaughtException(
                              ^

[ErrorReply: ERR unknown command 'JSON.SET', with args beginning with: 'Album:01GAZ32CZWSPB78HE8M75VH1GR' '.' '{"artist":"Mushroomhead","title":"The Righteous & The Butterfly","year":2014,"genres":["m' ]

我的redis-server在后台运行，并查看与Redis一起使用的主要数据库的情况，我去了redis-om-node。我将一些片段放在一起，试图了解整个流程。

import { Client, Entity, Schema, Repository } from "redis-om";

const client = new Client();
await client.open("redis://localhost:6379");

class Album extends Entity {}

const albumSchema = new Schema(Album, {
  artist: { type: "string" },
  title: { type: "text" },
  year: { type: "number" },
  genres: { type: "string[]" },
  outOfPublication: { type: "boolean" }
});

const albumRepository = client.fetchRepository(albumSchema);

const album = albumRepository.createEntity();
album.artist = "Mushroomhead";
album.title = "The Righteous & The Butterfly";
album.year = 2014;
album.genres = ["metal"];
album.outOfPublication = true;

const id = await albumRepository.save(album); // '01FJYWEYRHYFT8YTEGQBABJ43J'

console.log(id);

任何从redis-om-node或redis-om中脱脂的人都会识别此代码。

在package.json文件中，我已经安装了这些软件包，因为我将主数据库从 mongodb 更改为 redis 。
。

遇到一个错误，不知道它来自何处或什么是我现在已经处理过的事情了。我知道我不是奥利人。因此，请继续推动。

我以为不是我，而是代码或其他东西，所以我开始挖掘Google和Stackoverflow和Dev.to。我发现我可以创建一个新的存储库，而不是像我那样取出它，或者在这里完成了，const albumRepository = client.fetchRepository(albumSchema);我更新了代码。

import { Client, Entity, Schema, Repository } from "redis-om";

const client = new Client();
await client.open("redis://localhost:6379");

class Album extends Entity {}

const albumSchema = new Schema(
  Album,
  {
    artist: { type: "string" },
    title: { type: "text" },
    year: { type: "number" },
    genres: { type: "string[]" },
    outOfPublication: { type: "boolean" }
  },
  { dataStructure: "JSON" }
);

// const albumRepository = client.fetchRepository(albumSchema);
const repository = new Repository(client, albumSchema);

// const album = albumRepository.createEntity();
const album = repository.createEntity();
album.artist = "Mushroomhead";
album.title = "The Righteous & The Butterfly";
album.year = 2014;
album.genres = ["metal"];
album.outOfPublication = true;

// const id = await albumRepository.save(album);
const id = await repository.save(album);

console.log(id);

猜猜什么？有一个与以前的错误不同。

/home/user/Projects/web/ARMS-redis/node_modules/redis-om/dist/index.js:907
    const id = this.schema.generateId();
                           ^

TypeError: this.schema.generateId is not a function
    at Repository.createEntity (/home/user/Projects/web/ARMS-redis/node_modules/redis-om/dist/index.js:907:28)
    at file:///home/user/Projects/web/ARMS-redis/src/index.js:24:26
    at processTicksAndRejections (node:internal/process/task_queues:96:5)

我去了/home/user/Projects/web/ARMS-redis/node_modules/redis-om/dist/index.js:907

  createEntity(data = {}) {
    const id = this.schema.generateId();
    return new this.schema.entityCtor(this.schema, id, data);
  }

这是具有或指向不存在的generateId函数的createEntity。同一文件中有一个类，var Schema = class { ... }，它具有generateId函数。

我回到了挖掘，发现存储库中的另一种方法createAndSave({})。 express-redis-om-workshop。

我进行了修改：

import { Client, Entity, Schema, Repository } from "redis-om";

const client = new Client();
await client.open("redis://localhost:6379");

class Album extends Entity {}

const albumSchema = new Schema(
  Album,
  {
    artist: { type: "string" },
    title: { type: "text" },
    year: { type: "number" },
    genres: { type: "string[]" },
    outOfPublication: { type: "boolean" }
  },
  { dataStructure: "JSON" }
);

// const albumRepository = client.fetchRepository(albumSchema);
const repository = new Repository(client, albumSchema);

// const album = albumRepository.createEntity();
// const album = repository.createEntity();
// album.artist = "Mushroomhead";
// album.title = "The Righteous & The Butterfly";
// album.year = 2014;
// album.genres = ["metal"];
// album.outOfPublication = true;

// const id = await albumRepository.save(album);
// const id = await repository.save(album);

const id = await repository.createAndSave({
  artist: "Mushroomhead",
  title: "The Righteous & The Butterfly",
  title: "The Righteous & The Butterfly",
  year: 2014,
  genres: ["metal"],
  outOfPublication: true
});

console.log(id);

仍然，

/home/user/Projects/web/ARMS-redis/node_modules/redis-om/dist/index.js:907
    const id = this.schema.generateId();
                           ^

TypeError: this.schema.generateId is not a function
    at Repository.createEntity (/home/user/Projects/web/ARMS-redis/node_modules/redis-om/dist/index.js:907:28)
    at Repository.createAndSave (/home/user/Projects/web/ARMS-redis/node_modules/redis-om/dist/index.js:915:25)
    at file:///home/user/Projects/web/ARMS-redis/src/index.js:34:29
    at processTicksAndRejections (node:internal/process/task_queues:96:5)

此刻，我可以感觉到头骨（幽灵骑手）的压力和疲倦。我看了一些动漫，走了一点。首先，我回到了有关黑客马拉松的主要文章，然后我开始仔细阅读，寻找线索。 redis.io。两者之间有什么不同的redis.com？我不知道，所以我不知道。 redis.io，我读过，The open source, in-memory data store used by millions of developers as a database, cache, streaming engine, and message broker.，我记得我之前已经读过它或类似的东西。我像任何开发人员一样，单击 docs ，并且在我知道自己在redis-stack之前。我意识到， redis-stack 不仅与 redis 相同，还与Extends Redis with modern data models and processing engines. Includes documentation for the bundled Redis modules and RedisInsight.

相同

得出结论，我浪费了整天的方向，做正确的事。我安装了 redis-stack ，并使用此解决方案来修复另一个Could not create server TCP listening socket *:6379。

我将因此入睡。我想我明天会做得很好。
