An extra document is created

[georgeben]

Hey @pkosiec thanks for this cool tool. I noticed that I export an array of 6 objects from the collection folder, but 7 documents are created in the collection after seeding the database.

Here is my code:

// User roles is an array of 6 roles
module.exports = userRoles.map((role) => ({
  title: role,
  permissions: permissions[role],
}));

import { Seeder } from "mongo-seeding";
import path from "path";
import config from "../config";

const {
  dbHost, dbPort, dbName, dbUser, dbPassword,
} = config;
const seeder = new Seeder({
  database: "dburl",
  dropDatabase: false,
  dropCollections: true,
});

const collections = seeder.readCollectionsFromPath(
  path.resolve(__dirname, "../seeders"),
);

seeder.import(collections)
  .then(() => {
    console.log("Successfully seeded database");
  })
  .catch((err) => {
    console.log("Failed to seed the database", err);
  });

All 6 documents get created successfully, but one additional document containing just an ID is created also. It looks like this:

{"_id":{"$oid":"5ef62ba3b2928a7520202a01"}}

Hi @georgeben, are you sure the userRoles array doesn't contain any null/undefined value? Could you please print what exactly is in the array?

Also, are you sure there are no other files in the seeders directory?

Hey @pkosiec thank you for your quick reply. You're right, there was another file in my seeders directory. I am using babel to transpile my code before running it. After building my source code, I noticed babel was including some additional files that was causing that extra document to be created. I have resolved it now, so I'm closing this issue. Thanks once again.

@georgeben No problem - I'm glad you resolved your issue 🙂 Cheers!
