Typescript kendo.data.DataSourceSchemaModelFieldValidation required option is boolean

[John]

kendo.d.ts v2017.3.1026

should be 

 interface DataSourceSchemaModelFieldValidation {
  required?: boolean | { message: string };

 

to support custom required message.

Hello John,

In order to set a custom messages you can use the approach illustrated in the example below:

For more information on defining and using custom messages please refer to this article.

i use the approach of creating model definitions and use them many times in datasources.

     export var TALERTS_Model = kendo.data.Model.define({
        id: 'ALERT_ID',
        fields: {
            'ALERT_ID': { type: 'number' },
            'CLASS_NAME': { type: 'string', validation: { maxLength: 50, required: { message: 'this is required' } } },
            'DESCRIPTION': { type: 'string', validation: { maxLength: 100 } },
            'CATEGORY': { type: 'string', validation: { maxLength: 100 } },
        }
    });


 

the above is invalid because required accepts boolean only and not object.

kendo.d.ts

interface DataSourceSchemaModelFieldValidation {
    required?: boolean;
    min?: any;
    max?: any;
    minLength?: any;
    maxLength?: any;
    [rule: string]: any;
}

 

and is not the best solution to work with any data type when using typescript as when defining a model in datasource.

Hi John,

Thank you for reporting the behavior to us. I have logged this and we will update the TypeScript definitions as soon as possible. Until then I can suggest modifying the Kendo typescript file locally so that there is no error when using custom messages. 

As a token of gratitude for reporting this to us I have updated your Telerik points.
