Question

What is the best way to link a newly created contact to the current user in Mongoose?

I'm faced with the challenge of creating a contact that is specifically added to the current user's contact array.

Currently, my controller only creates a generic contact and doesn't cater to the individual user.

Controller:

function contactsCreate(req, res) {

  Contact
    .create(req.body)
    .then(contact => res.status(201).json(contact))
    .catch(() => res.status(500).json({ message: 'Something went wrong'}));
}

Contact Model:

const contactSchema = new Schema({

  firstName: String,
  lastName: String,
  email: String,
  job: String,
  address: String,
  number: Number
});

User model:

const userSchema = new mongoose.Schema({

  username: { type: String, unique: true, required: true },
  email: { type: String, unique: true, required: true },
  passwordHash: { type: String, required: true },
  contacts: [{ type: mongoose.Schema.ObjectId, ref: 'Contact' }]
});

Answer №1

If you have the username available in the request object, you can use the following code to successfully create a new contact:

async function addNewContact(req, res) {
  const username = req.User.username

  try {
      const newContact = await Contact.create(req.body)
      const user = await User.findOne({username})
      user.contacts.push(newContact)
      await user.save()
      return res.status(201).json(newContact)
  } catch (error) {
      return res.status(500).json({ message: 'An error occurred while adding the contact'})
  }
}

Big thanks to LazyElephant for the helpful input. Here is the modified solution:

const createNewContact = async (req, res) => {
  const userID = req.user.id;

  try {
    const contact = await Contact.create(req.body);
    const user = await User.findById(userID);
    user.contacts.push(contact);
    await user.save();
    return res.status(201).json(contact);
  } catch (error) {
    return res.status(500).json({ message: 'An error occurred, please try again'});
  }
}
