question: get constrains in decorators and not the message about class-validator

[emir-gradient]

Hello.

In your custom validator, you can utilize snippet similar to this one:

import { getMetadataStorage, MetadataStorage } from 'class-validator';

// ... Some other code
const dataType = CreateAdminDTO; // you put your data type here (one you are validating). I think you can use ValidationError.target for this.
const metadataStorage: MetadataStorage = getMetadataStorage();
const metas = metadataStorage.getTargetValidationMetadatas(dataType, null, false, false);

console.log(metas);

// Result is like:
//   [
// ValidationMetadata {
//   groups: [],
//   each: false,
//   context: undefined,
//   type: 'customValidation',
//   name: 'minLength',
//   target: [class CreateAdminDTO],
//   propertyName: 'username',
//   constraints: [ 4 ], => validator was @minLength(4)
//   constraintCls: [class CustomConstraint],
//   validationTypeOptions: undefined
// },
// ... other metadatas
// ]
