pq: malformed array literal: - postgresql

Question

I want to insert json array request like
{
"name": "Sales Commission",
"commission_type":"ZCo6QCHOBth7MD-8sohHQ",
"time_period_from": "2022-05-13 12:00:00",
"time_period_to": "2022-05-18 12:00:00",
"service_id": [
{
"service_id": "1",
"service_type": "1",
"commission_type": "1",
"commission_rate": "1.50"
}
],
"package_id": [
{
"package_id": "1",
"package_type": "1",
"commission_type": "1",
"commission_rate": "1.50"
}
],
"product_id": [
{
"product_id": "1",
"product_type": "1",
"commission_type": "1",
"commission_rate": "1.50"
}
],
"employee_id": [
{
"employee_id": "1",
"commission_type": "1",
"commission_rate": "10.50"
}
],
"status": "active"
}
I am using Golang with Postgres. I had made struct of the Model which is below:
type AutoGenerated struct {
Name string `json:"name"`
CommissionType string `json:"commission_type"`
TimePeriodFrom string `json:"time_period_from"`
TimePeriodTo string `json:"time_period_to"`
Services []Services `json:"service_id"`
Packages []Packages `json:"package_id"`
Products []Products `json:"product_id"`
Employees []Employees `json:"employee_id"`
Status string `json:"status"`
}
type Services struct {
ServiceID string `json:"service_id"`
ServiceType string `json:"service_type"`
CommissionType string `json:"commission_type"`
CommissionRate string `json:"commission_rate"`
}
type Packages struct {
PackageID string `json:"package_id"`
PackageType string `json:"package_type"`
CommissionType string `json:"commission_type"`
CommissionRate string `json:"commission_rate"`
}
type Products struct {
ProductID string `json:"product_id"`
ProductType string `json:"product_type"`
CommissionType string `json:"commission_type"`
CommissionRate string `json:"commission_rate"`
}
type Employees struct {
EmployeeID string `json:"employee_id"`
CommissionType string `json:"commission_type"`
CommissionRate string `json:"commission_rate"`
}
Request which is being decoded
var ReqMapData model.AutoGenerated
err := json.NewDecoder(r.Body).Decode(&ReqMapData)
if err != nil {
log.Println(err)
}
While performing data insertion I am facing this issue like "pq: malformed array literal: "[{"service_id":"1","service_type":"1","commission_type":"1","commission_rate":"1.50"}]"""
Code which inserts data
serJson, errJson := json.Marshal(reqMap.Services)
if errJson != nil {
util.CheckErrorLog(r, errJson)
return false
}
pkgJson, errJson1 := json.Marshal(reqMap.Packages)
if errJson1 != nil {
util.CheckErrorLog(r, errJson1)
return false
}
proJson, errJson2 := json.Marshal(reqMap.Products)
if errJson2 != nil {
util.CheckErrorLog(r, errJson2)
return false
}
empJson, errJson3 := json.Marshal(reqMap.Employees)
if errJson3 != nil {
util.CheckErrorLog(r, errJson3)
return false
}
Qry.WriteString("INSERT INTO commission_template(id, name, commission_type, time_period_from, time_period_to, service_id, package_id, product_id, employee_id, status) ")
Qry.WriteString(" VALUES ($1, $2, $3, $4, $5, $6, $7, $8, $9, $10);")
err := ExecuteNonQuery(Qry.String(), nanoid, reqMap.Name, reqMap.CommissionType, reqMap.TimePeriodFrom, reqMap.TimePeriodTo, string(serJson), string(pkgJson), string(proJson), string(empJson), reqMap.Status)
if err != nil {
util.CheckErrorLog(r, err)
return false
}
// ExecuteNonQuery - Update, Insert Query
func ExecuteNonQuery(SQLQry string, params ...interface{}) error {
_, err := VDB.Exec(SQLQry, params...)
return err
}
