Update Models - Matrix Systems

[casaltarelli]

Purpose We have decided to remove the current Model DeviceAssignment and instead have chosen to incorporate user_id directly into our Device model. This will require for us to add additional attributes into our Device model such as:

• User ID [FK]
• Device Name
• is Active

Expected Behavior Upon the creation of a new Device record within our database we need to supply the respective user for which the device belongs too. Our Device model should contain the following attributes:

• device_id [PK]
• user_id [PK, FK]
• registration_date
• device_name
• os_version
• mac_address
• is_active
