// This is a Prisma database schema definition, which describes the structure and relationships between various entities in the database. Here's a brief overview of the different models:

// Publisher: Represents a publisher, with attributes such as first name, last name, email, phone, age, and availability. A publisher can have many availabilities and assignments, and can also have multiple user accounts and sessions.
// Availability: Represents the availability of a publisher on a specific day and time range. An availability belongs to a publisher and can have a name, day of the week, day of the month, start time, and end time.
// CartEvent: Represents a cart event, which is an event that requires a certain number of publishers to work. A cart event has a start and end time, a duration, and can have multiple shifts. It also has a location and an event type.
// Shift: Represents a shift, which is a specific time period during a cart event where one or more publishers are required to work. A shift belongs to a cart event and can have a name, start and end time, and can require transport.
// Assignment: Represents an assignment of a publisher to a specific shift. An assignment belongs to a shift and a publisher and can be tentative or final.
// Location: Represents a location where a cart event can take place. A location can have a name, address, and multiple cart events.
// Overall, this schema seems to represent a system for managing publishers and their assignments to cart events, including their availabilities and locations.
