Mongoose Models

Create a User model

1. Create a User model:

   user/models.js

    'use strict';
   
    var mongoose = require('mongoose');
    var Schema = mongoose.Schema;
   
    // define the userSchema
    var userSchema = new Schema({
      name  : {
        givenName   : String,
        familyName  : String
      }
    });
   
    // Export the User model
    exports.User = mongoose.model('User', userSchema);
   

   For more information on mongoose please read mongoose documentation

2. Check the test runner.

   You should now see that our test passed.

    addition
      ✓ should add 1+1 correctly
   
    Users: models
      #create()
        ✓ should create a new User
   
    ✔ 2 tests complete (21 ms)
   

Add fields to the User model

3. First modify the test:

    describe('#create()', function () {
      it('should create a new User', function (done) {
        // Create a User object to pass to User.create()
        var u = {
          name: {
            givenName: 'Barack',
            familyName: 'Obama'
          },
          // new attributes
          emails: [
            {
              type: 'home',
              value: 'home@example.com'
            },
            {
              type: 'work',
              value: 'work@example.com'
            }
          ]
        };
        User.create(u, function (err, createdUser) {
          // Confirm that that an error does not exist
          should.not.exist(err);
          // verify that the returned user is what we expect
          createdUser.name.givenName.should.equal('Barack');
          createdUser.name.familyName.should.equal('Obama');
          // new tests
          createdUser.emails[0].type.should.equal('home');
          createdUser.emails[0].value.should.equal('home@example.com');
          createdUser.emails[1].type.should.equal('work');
          createdUser.emails[1].value.should.equal('work@example.com');
          // Call done to tell mocha that we are done with this test
          done();
        });
      });
    });
   

   You should see that the test are now failing.

    addition
      ✓ should add 1+1 correctly
   
    Users: models
      #create()
        1) should create a new User
   
    ✖ 1 of 2 tests failed:
   
    1) Users: models #create() should create a new User:
       TypeError: Cannot read property '0' of undefined
   

4. Add an emails list attribute to the User schema:

    // ...
    // define the emailSchema
    var emailSchema = new Schema({
      // Since `type` is special keyword in mongoose we must set the def. to
      // and object. I.e. this would not work:
      // type: String,
      type  : {type: String},
      value : String
    });
   
    // define the userSchema
    var userSchema = new Schema({
      name  : {
        givenName   : String,
        familyName  : String
      },
      emails: [emailSchema]
    });
    // ...
   

5. Test should now be passing. If they are not try restarting the test runner. command+c and running npm start
