Now }, createdBy: String, tasks: String }); This is our starting point, and we will build upon it when we look at more complex schemas in Chapter 10, Complex Schemas. For now we have these basic data objects as mentioned previously in this chapter. 032Z"), "__v" : 0 } [ 39 ] Schemas and Models Improving the Project schema Throughout the rest of the book we will be improving this schema, but the beauty of using Mongoose is that we can do this relatively easily. Putting together a basic schema like this to build upon is a great approach for prototyping—you have the data you need there, and can add complexity where you need, when you need it.
With this 1:1 relationship, it is the model that handles all document interaction— creating, reading, saving, and deleting. This makes the model a very powerful tool. Building the model, as we have seen, is pretty straightforward. model( 'User', userSchema ); If using a named Mongoose connection, the approach is very similar. model( 'User', userSchema ); Instances We'll be looking at how we interact with the data in the next chapter, but it is useful to have a good understanding of how a model works.
Boolean This SchemaType has only two values: true or false. Buffer This SchemaType is primarily used for storing binary information, for example, images stored in MongoDB. ObjectId This SchemaType is used to assign a unique identifier to a key other than _id, for example, a foreign key for referencing another document (see Chapter 10, Complex Schemas for more about this). ObjectId. ObjectId }); Mixed A mixed data object can contain any type of data. Mixed. Mixed }); [ 33 ] Schemas and Models While this sounds like it might be great, there is a big caveat.
