Node.js, MongoDB, and AngularJS Web Development

Compiling a Model

Once you have defined the Schema object for a model, you need to compile it into a Model object. When Mongoose compiles the model, it uses the connection to the MongoDB database established by mongoose.connect() to ensure that the collection is created and has the appropriate indexes, as well as required and unique settings, when applying changes.

The compiled Model object acts in much the same way as the Collection object defined in Chapter 13. It provides the functionality to access, update, and remove objects in the model and subsequently in the MongoDB collection.

To compile the model, you use the model() method in the mongoose module. The model() method has the following syntax:
