How to use daterange type?

[esoteloferry]

Schema DB:

create table if not exists dayoffs (
id int GENERATED ALWAYS AS IDENTITY,
PRIMARY KEY(id),
user_id int not null,
from_to DATERANGE not null
);

The code generated is:

// Dayoff is an object representing the database table.
type Dayoff struct {
	ID     int    `boil:"id" json:"id" toml:"id" yaml:"id"`
	UserID int    `boil:"user_id" json:"user_id" toml:"user_id" yaml:"user_id"`
	FromTo string `boil:"from_to" json:"from_to" toml:"from_to" yaml:"from_to"`

	R *dayoffR `boil:"-" json:"-" toml:"-" yaml:"-"`
	L dayoffL  `boil:"-" json:"-" toml:"-" yaml:"-"`
}

Questions:

1. FromTo in code generated has string type. Is that ok?
   I would like to insert a record, and tried both methods below but they don' t work
2. How can I insert a record?

	dayoffDB := models.Dayoff{
		UserID: p.UserID,
		FromTo: fmt.Sprintf(`'[%s , %s]'::daterange`, p.FromDate.String(), p.ToDate.String()),
	}

or

	dayoffDB := models.Dayoff{
		UserID: p.UserID,
		FromTo: fmt.Sprintf(`[%s , %s]`, p.FromDate.String(), p.ToDate.String()),
	}
