Question

我是后端开发的新手，我在将 User 模型与 Profile 模型连接时遇到了一些问题。当用户在 username 模型中设置它们时，我还想在配置文件模型中自动生成 User。我不知道该怎么做。这是我的代码

Resolver.js

Mutation: {
    signUpUser: async (parent, { userInput }) => {
      const { email, username, password } = userInput;
      const errors = [];
      if (!validator.isEmail(email)) {
        errors.push({
          message: "Invalid Email",
        });
      }
      const existingUser = await User.findOne({ email: email });
      if (existingUser) {
        const error = new Error("User exists already");
        throw error;
      }
      if (errors.length > 0) {
        const error = new Error("Invalid Input");
        error.data = errors;
        error.code = 402;
        throw error;
      }
      const hashedPassword = await bcrypt.hash(password, 12);
      const user = new User({
        email: email,
        password: hashedPassword,
        username: username,
      });
      
      const createdUser = await user.save();
      
      return {
        ...createdUser._doc,
        _id: createdUser._id.toString(),
      };
    },

用户模型

const mongoose = require("mongoose");
const Schema = mongoose.Schema;

const userSchema = new mongoose.Schema(
  {
    email: {
      type: String,
      required: true,
    },
    password: {
      type: String,
      required: true,
    },
    username: {
      type: String,
      required: true,
    },
    status: {
      type: String,
      default: "I am new!",
    },
    posts: [
      {
        type: Schema.Types.ObjectId,
        ref: "Post",
      },
    ],
    profile: {
      type: Schema.Types.ObjectId,
      ref: "Profile",
    },
  },
  { timestamps: true }
);


module.exports = mongoose.model("User", userSchema);

配置文件模型

const mongoose = require("mongoose");

const Schema = mongoose.Schema;
const profileSchema = new mongoose.Schema(
  {
    firstName: {
      type: String,
    
      default: null,
    },
    lastName: {
      type: String,
  
      default: null,
    },
    bio: {
      type: String,
      default: null,
    },
    profilePic: {
      type: String,
      default: null,
    },
    username: {
      type: String,
      default: null,
    },
    url: {
      type: String,
      default: null,
    },
    user: {
      type: Schema.Types.ObjectId,
      ref: "User",
    }
  },
  { timestamps: true }
);

module.exports = mongoose.model("Profile", profileSchema);

任何帮助都会很棒。谢谢你。我在这里使用 Graphql 和 apollo。
