typescript - Check for a Valid Instance of in NestJS

Question

I'v'e been trying to validate my request based on my entity (Product) dto. Everything is working fine, except for 'From' and 'To' fields. Customer and Type fields are validated correctly, if i try to send a request with wrong data, that's what i get.

"statusCode": 400,
"message": [
    "type must be a valid enum value"
],
"error": "Bad Request"

Expected Behavior ProductDto should validate 'From' and 'To' fields from LeagueEntity.

Answer 1

You need to add @Type(() => LeagueEntity) to your from and to properties so that class-transformer and class-validator know what they are properly validating. As these are sub classes, you'll probably want to add @ValidateNested() as well
