Question

Async addReferral(userId: string, referral_code?: string | undefined) {

// Check that the user hasn't been referred before
const referral = await this.prisma.referralCode.findMany({
where: {
user_id: userId,
type: ReferralType.USER,
},
});

if (referral?.length > 0) {
throw new BadRequestException(USER_ALREADY_REFERRED);
}

// If the code exists, check its validity
const referralCode = await this.prisma.referralCode.findUnique({
where: {
code: referral_code,
},
});

if (!referralCode) {
throw new BadRequestException(INVALID_REFERRAL_CODE);
}

// DB writes after this (redacted)
}
