Checkbox

A checkbox field represents a boolean (true/false) value.

Options:

  • defaultValue (default: false): This value will be used for the field when creating items if no explicit value is set.
  • db.map: Adds a Prisma @map attribute to this field which changes the column name in the database
  • graphql.read.isNonNull (default: false): If you have no read access control and you don't intend to add any in the future, you can set this to true and the output field will be non-nullable. This is only allowed when you have no read access control because otherwise, when access is denied, null will be returned which will cause an error since the field is non-nullable and the error will propagate up until a nullable field is found which means the entire item will be unreadable and when doing an items query, all the items will be unreadable.
  • graphql.create.isNonNull (default: false): If you have no create access control and you want to explicitly show that this is field is non-nullable in the create input you can set this to true and the create field will be non-nullable and have a default value at the GraphQL level. This is only allowed when you have no create access control because otherwise, the item will always fail access control if a user doesn't have access to create the particular field regardless of whether or not they specify the field in the create.
