The official documentation can be found here.

MongoDb Query a One-To-Many Relationship

enter image description here

I have the following Documents, and I would like to return all the Organizations that a User belongs to, however I can’t figure out the exact query I need to write?

I tried this, But I get an error

const organization = await Organization.find({ users: {$in: req.currentUser!.id} });

organization.ts(13, 3): The expected type comes from property 'users' which is declared here on type 'FilterQuery<OrganizationDoc>'

Model for Organization


import mongoose from "mongoose";
import { updateIfCurrentPlugin } from "mongoose-update-if-current";
import { UserDoc } from "./user";
import { PlanDoc } from "./plan";
interface OrganizationAttrs {
  name: string;
  users: UserDoc[];
  plan: PlanDoc;
}

interface OrganizationDoc extends mongoose.Document {
  name: string;
  users: UserDoc[];
  plan: PlanDoc;
  version: number;
}

interface OrganizationModel extends mongoose.Model<OrganizationDoc> {
  build(attrs: OrganizationAttrs): OrganizationDoc;
}

const organizationSchema = new mongoose.Schema(
  {
    name: {
      type: String,
      required: true,
    },
    users: [
      {
        type: mongoose.Schema.Types.ObjectId,
        ref: "User",
      },
    ],
    plan: {
      type: mongoose.Schema.Types.ObjectId,
      ref: "Plan",
    },
  },
  {
    toJSON: {
      transform(doc, ret) {
        ret.id = ret._id;
        delete ret._id;
      },
    },
  }
);
organizationSchema.set("versionKey", "version");
organizationSchema.plugin(updateIfCurrentPlugin);

organizationSchema.statics.build = (attrs: OrganizationAttrs) => {
  return new Organization(attrs);
};

const Organization = mongoose.model<OrganizationDoc, OrganizationModel>(
  "Organization",
  organizationSchema
);

export { Organization };

I think the issue is that users is an array of UserDoc types?

    Because users is an array of UserDoc. first find the user then query Organization by the user that you found.

    import express, { Request, Response } from "express";
import { Organization } from "../models/organization";
import { User } from "../models/user";

const router = express.Router();

router.get("/api/organization", async (req: Request, res: Response) => {
  const user = await User.findById(req.currentUser!.id);
  if (user) {
    const organization = await Organization.find({ users: user });
    res.send(organization);
  }
});

export { router as indexOrganizationRouter };

    well you can do that with javascript but in typescript, $in request an Array so you can easy fixed it by put userId to array

    const organization = await Organization.find({ users: {$in: [req.currentUser.id]} });
