Adding properties

Properties have types. In neomodel, all the basic types are available:

• String
• Integer
• Float
• Boolean
• Date, DateTime
• UniqueID

Apart from that, there are other extra types that exist as well, as follows:

• JSON
• Email (a string with extra checks for its format)
• Point (the Neo4j spatial type)

Each of these properties is created with some optional parameters to define; for instance, whether they are required or not.

For our purposes, let's create a User model with the following properties:

• login (String): Required and a primary key
• password (String): Required
• email (Email): Optional
• birth_date (Date): Optional

The User model should look like this:

class User(StructuredNode):
    login = StringProperty(required=True, primary=True)
    password = StringProperty(required=True)
    email = EmailProperty()
    birth_date = DateProperty()

Now that our model exists, we can use it to create and retrieve nodes, without writing any Cypher queries.
