How to rename result field in golang rethinkdb driver gorethink?
问题
以下是要翻译的内容：
r.table('customers').map(function(purchase) {return {zip:customer('address')('zip'), product:purchase('name')};}).run(...)
在gorethink中，如何表示map({"new_column_name":Row.Field("original_column_name")})？
非常感谢任何帮助...

gorethink

我刚刚将你的Node.js代码（在你之前的版本中）转换成了Golang：
session, err := r.Connect(r.ConnectOpts{Address: "localhost:28015",})if err != nil {return}res, err := table.ConcatMap(func(customer r.Term) interface{} {return customer.Field("purchases").Map(func(purchase r.Term) interface{} {return map[string]interface{}{"zip": customer.Field("address").Field("zip"),"product": purchase.Field("name"),}})}).Run(session)if err != nil {return}defer res.Close()var response interface{}for res.Next(&response) {fmt.Println(response)}
以上是翻译好的代码部分。

I just port your node.js code (in your former version) to golang :
session, err := r.Connect(r.ConnectOpts{Address: "localhost:28015",})if err != nil {return}res, err := table.ConcatMap(func(customer r.Term) interface{} {return customer.Field("purchases").Map(func(purchase r.Term) interface{} {return map[string]interface{}{"zip": customer.Field("address").Field("zip"),"product": purchase.Field("name"),}})}).Run(session)if err != nil {return}defer res.Close()var response interface{}for res.Next(&response) {fmt.Println(response)}
