DateTime validation not accepting valid DateTime string #7657

ABP Framework version: v5.3.0

UI Type: Angular

Database System: EF Core (PostgreSQL.)

Tiered (for MVC) or Auth Server Separated (for Angular): no

When I try to set a datetime string in Angular that is a valid format to a datetime field in a DTO I get a validation exception in Angular.

Even when I try a different format:

I can't find anything in the Validation documentation that addresses this automatic datatype validation. We haven't set any special rules for validation of this field or defined a specific format for it.

It WILL accept an ordinary date string without the time like this: "13/04/2024".

How do I get it to accept a value that includes time?

The DTO:

export interface GetRunListDto extends PagedAndSortedResultRequestDto {
  filterText?: string;
  name?: string;
  startDateTimeMin?: string;
  startDateTimeMax?: string;
  scenarioName?: string;
}

 "eWater.Repros.Runs.GetRunListDto": {
      "baseType": "Volo.Abp.Application.Dtos.PagedAndSortedResultRequestDto",
      "isEnum": false,
      "enumNames": null,
      "enumValues": null,
      "genericArguments": null,
      "properties": [
        {
          "name": "FilterText",
          "jsonName": null,
          "type": "System.String",
          "typeSimple": "string",
          "isRequired": false
        },
        {
          "name": "Name",
          "jsonName": null,
          "type": "System.String",
          "typeSimple": "string",
          "isRequired": false
        },
        {
          "name": "StartDateTimeMin",
          "jsonName": null,
          "type": "System.DateTime?",
          "typeSimple": "string?",
          "isRequired": false
        },
        {
          "name": "StartDateTimeMax",
          "jsonName": null,
          "type": "System.DateTime?",
          "typeSimple": "string?",
          "isRequired": false
        },
        {
          "name": "ScenarioId",
          "jsonName": null,
          "type": "System.Guid?",
          "typeSimple": "string?",
          "isRequired": false
        }
      ]
    }

    HI,

    here is the DateTimeModelBinder to convert string to datetime.

    https://github.com/dotnet/aspnetcore/blob/main/src/Mvc/Mvc.Core/src/ModelBinding/Binders/DateTimeModelBinder.cs#L35

    You can see the supported time format in swagger

    We aren't using MVC we are using Angular front end. Is this something I have to define on the DTO on the server side?

    We don't use MVC so can DateTimeModelBinder still be used?

    Hi,

    Yes, the server-side uses it.

    Well I added the MVC modules but there's nothing on how I'm supposed to make this class work.

    Hi,

    I mean your time format is not correct.

    This is the code logic for binding time https://github.com/dotnet/aspnetcore/blob/main/src/Mvc/Mvc.Core/src/ModelBinding/Binders/DateTimeModelBinder.cs#L35
