how to validate date field for if nothing is passed see the current date

Question

I have an endpoint as follows:

[HttpGet]
[ProducesResponseType(typeof(IEnumerable<TestsDto>), (int)HttpStatusCode.OK)]
public async Task<ActionResult<IEnumerable<TestsDto>>> GetAsync(Guid textId, Guid phraseId, Guid heightId, Guid? weightId, Guid? productId, decimal? value, DateTime? date)
{
    
    var test= await _testingHandler.GetAsync(textId, phraseId, currencyId, heightId, weightId, value, date );
    return Ok(apps);
}

How do I validate, if the last field that is date no value is passed to it I always assign the current date in this field ?

Answer 1

You want to do this check only on the API right? There is no magic, you will need to create a method or just a conditional to check for you.

if (date == null) date = Datetime.Now;

Or you could create a validation class using libraries like Fluentvalidation /Abstractvalidator to perform this action for you.

Hello, see if this works for you:

[HttpGet]
[ProducesResponseType(typeof(IEnumerable<TestsDto>), (int)HttpStatusCode.OK)]
public async Task<ActionResult<IEnumerable<TestsDto>>> GetAsync(Guid textId, Guid phraseId, Guid heightId, Guid? weightId, Guid? productId, decimal? value, DateTime? date)
{
    if (date == null)
         date = DateTime.Now;
    var test= await _testingHandler.GetAsync(textId, phraseId, currencyId, heightId, weightId, value, date );
    return Ok(apps);
}
