In the DB I have a column name time and it's type time,
On my code I'm using nestjs with class-validator and the user send this value for time 10:13:06 ( Assuming it is in 12h format ).
How do I validate this value using class-validator
current code
import {
IsDateString,
IsNotEmpty,
} from 'class-validator';
export class CreateFilmTime {
@IsDateString() // O know it's for date string
time: Date;
}
You could use @Matches with a regex like this:
@Matches(/^(1[0-2]|0?[1-9]):([0-5]?[0-9]):([0-5]?[0-9])$/)
You can reference @IsMilitaryTime decorator the class-validator documentation
const now = new Date();
const hours = String(now.getHours()).padStart(2, '0');
const minutes = String(now.getMinutes()).padStart(2, '0');
`${hours}:${minutes}` //hh:mm
According to the documentation, checks if the string represents a time without a given timezone in the format HH:MM (military). If the given value does not match the pattern HH:MM, then it returns false.
Concatenate to use and pass the validation using:
@IsMilitaryTime()
readonly time: string;
