    Invoice,
    "invoice",
    ["name", "number"],
    {
        number: String,
        amount: f64,
        due_date: Option<String>,
    },
    validate: {
        create: {
            number: [required, string_length(3, 50)],
            amount: [required, positive],
        },
        update: {
            amount: [optional, positive],
        },
    },
    filters: {
        create: {
            number: [trim, uppercase],
            amount: [round_decimals(2)],
        },
    }
