Change how swagger ui sends array of values

[kasir-barati]

I am using NestJS and class-validator. We can in class-validator do this as we all know:

enum Gender { male = 'male', female = 'female' }

class A {
  @ApiProperty({
    required: false,
    description: `filter result by their gender`,
    example: [Gender.male],
    enum: Gender,
    type: [Gender],
  })
  @IsArray()
  @IsEnum(Gender, { each: true })
  genders: Gender[];
}

This A is used to validate query string Then when we sends a request with swagger it will sends something like this if we specify one age. http://localhost:9000/endpoint?genders=male

But this will make class-validator unsatisfied in my experience. I mean it throw an Error and says genders is not an array.

What will work?

Sending this request http://localhost:9000/endpoint?genders[]=male. class-validator understand how to deal with genders[] but if you sends genders you have to do this: http://localhost:9000/endpoint?genders=male&genders=male

I suggest raising this directly with https://github.com/swagger-api/swagger-ui

@kasir-barati Any secret knowledge you've obtained in the last few months that you might share with me?

Kinda have the same issue but haven't managed to dig out a solution
