Gorethink Insert Issue
问题
var data = map[string]interface{}{
"json_received": [
{
"ezpOrderId": "ezp_123",
"firstName": "Vasanth",
"lastName": "K",
"orderDesc": "Sample"
}
],
"created_on": "03-22-2015",
"status": "1"
}
result, err := r.Table("order_json").Insert(data).RunWrite(session)
当我尝试运行这个程序时，我得到了一个错误，错误信息是"json_received"后面缺少操作数。
请帮助我通过Go编程将数据变量插入到RethinkDB中。
英文:
var data = map[string]interface{}{"json_received": [{"ezpOrderId": "ezp_123","firstName": "Vasanth","lastName": "K","orderDesc": "Sample"}]"created_on": "03-22-2015","status": "1"}result, err := r.Table("order_json").Insert(data).RunWrite(session)
When i m tried to run this program i got the error as "missing operand" after "json_received":[ line.
Please help me to insert the data variable in rethink db via go programming..

Go语言不支持像你尝试做的那样的JSON字面量。
这是一个修复后的版本（在Play上查看）。
请注意，对于所有的子结构，在创建时必须声明类型。
你试图让json_received成为一个JSON对象列表，所以我使用了[]map[string]interface{}。
另外，正如其他人指出的，多行的map/list字面量在每行后面必须有一个逗号，比如：orderDesc，status。
package mainimport "fmt"func main() {var data = map[string]interface{}{"json_received": []map[string]interface{}{{"ezpOrderId": "ezp_123","firstName": "Vasanth","lastName": "K","orderDesc": "Sample",},},"created_on": "03-22-2015","status": "1",}fmt.Printf("%#v\n", data)//result, err := r.Table("order_json").Insert(data).RunWrite(session)}
英文:
Go does not support json literals like you are trying to do.
Here's a fixed version (on Play).
Notice that for all sub structures, you must declare the type when creating it.
You were trying to make json_recieved to be a list of json objects, so I used []map[string]interface{}.
And, as others have pointed out, multi-line map/list literals must have a comma after each line, as in: orderDesc, status.
package main
import "fmt"func main() {var data = map[string]interface{}{"json_received": []map[string]interface{}{{"ezpOrderId": "ezp_123","firstName": "Vasanth","lastName": "K","orderDesc": "Sample",},},"created_on": "03-22-2015","status": "1",}fmt.Printf("%#v\n", data)//result, err := r.Table("order_json").Insert(data).RunWrite(session)}

你在json_received数组后面漏掉了逗号。
"json_received": [{"ezpOrderId": "ezp_123","firstName": "Vasanth","lastName": "K","orderDesc": "Sample"}], // <--
英文:
you are missing comma after json_received array
"json_received": [{"ezpOrderId": "ezp_123","firstName": "Vasanth","lastName": "K","orderDesc": "Sample"}] , //<--
