How can I clean up this return type for neoism go-lang?
问题
我正在尝试使用neoism创建的这个模型现在正在工作，但我无法弄清楚如何使返回类型更短或更清晰。
可能有一种方法可以将这个：
[]struct { UserId string "json:\"account.UserId\""; FirstName string "json:\"account.firstName\""; LastName string "json:\"account.lastName\"" }
变成：
[]Account 或其他什么东西
以下是要翻译的代码：
package models
import (
"errors"
"strconv"
"time"
"github.com/jmcvetta/neoism"
)
var (
Accounts map[string]*Account
)
var (
db *neoism.Database
)
func panicErr(err error) {
if err != nil {
panic(err)
}
}
type Account struct {
UserId string `json:"account.UserId"`
FirstName string `json:"account.firstName"`
LastName string `json:"account.lastName"`
}
func init() {
var err error
db, err = neoism.Connect("http://neo4j:password@localhost:7474/db/data")
if err != nil {
panic(err)
}
}
func GetAccounts() []struct {
UserId string `json:"account.UserId"`
FirstName string `json:"account.firstName"`
LastName string `json:"account.lastName"`
} {
stmt := `
MATCH (account:Account) RETURN account.UserId, account.firstName, account.lastName
`
res := []struct {
UserId string `json:"account.UserId"`
FirstName string `json:"account.firstName"`
LastName string `json:"account.lastName"`
}{}
cq := neoism.CypherQuery{
Statement: stmt,
Result: &res,
}
err := db.Cypher(&cq)
panicErr(err)
return res
}

我是Go的新手，我正在根据这些neoism的示例进行开发：
https://gist.github.com/verdverm/b43444063995a7f5b913
有很多示例，但verdverm只是输出而不是返回。
我还有一个控制器，我想在其中输出JSON。
package controllers
import (
"github.com/astaxie/beego"
"social/models"
)
type AccountsController struct {
beego.Controller
}
func (c *AccountsController) Get() {
c.Data["json"] = models.GetAccounts()
c.ServeJson()
}
希望对Go的新手有所帮助！

This model I am trying to make with neoism is working now but I can't figure out how to make the return type shorter and or cleaner looking.
There must be a way to make this:
[]struct { UserId string "json:\"account.UserId\""; FirstName string "json:\"account.firstName\""; LastName string "json:\"account.lastName\"" }
Into:
[]Account or something
package models
import (
"errors"
"strconv"
"time"
// "fmt"
"github.com/jmcvetta/neoism"
)
var (
Accounts map[string]*Account
)
var (
db *neoism.Database
)
func panicErr(err error) {
if err != nil {
panic(err)
}
}
type Account struct {
UserId string `json:"account.UserId"`
FirstName string `json:"account.firstName"`
LastName string `json:"account.lastName"`
}
func init() {
var err error
db, err = neoism.Connect("http://neo4j:password@localhost:7474/db/data")
if err != nil {
panic(err)
}
}
// map[lastName:PATRUS UserId:7f7014f9-bd59-4739-8e1b-5aebfa00f4c5 firstName:LARISSA]
func GetAccounts() []struct { UserId string "json:\"account.UserId\""; FirstName string "json:\"account.firstName\""; LastName string "json:\"account.lastName\"" } {
stmt := `
MATCH (account:Account) RETURN account.UserId, account.firstName, account.lastName
`
res := []struct {
UserId string `json:"account.UserId"`
FirstName string `json:"account.firstName"`
LastName string `json:"account.lastName"`
}{}
// construct query
cq := neoism.CypherQuery{
Statement: stmt,
Result: &res,
}
// execute query
err := db.Cypher(&cq)
panicErr(err)
return res
}
Here is another copy:

I am new to go and I am going off of these examples for neoism:
https://gist.github.com/verdverm/b43444063995a7f5b913
There are many examples, but verdverm is always just outputting and not returning.
I have a controller as well where I would like to output the json.
package controllers
import (
"github.com/astaxie/beego"
"social/models"
)
type AccountsController struct {
beego.Controller
}
func (c *AccountsController) Get() {
c.Data["json"] = models.GetAccounts()
// c.Data["json"] = "hello world"
c.ServeJson()
}
Thanks for any help/tips for go newbie!

GetAccounts()函数能够返回一个账户指针的数组吗？
func GetAccounts() []*Account {}

Can getAccounts return an array of account pointers?
func GetAccounts() []*Account {}

包模型
导入 (
"错误"
"strconv"
"时间"
// "fmt"
"github.com/jmcvetta/neoism"
)
var (
账户映射[string]*账户
)
var (
数据库 *neoism.数据库
)
func 报错(err 错误) {
如果 err != nil {
报错(err)
}
}
类型 账户 结构体 {
用户ID 字符串 json:"account.UserId"
名字 字符串 json:"account.firstName"
姓氏 字符串 json:"account.lastName"
}
初始化() {
var err 错误
数据库, err = neoism.连接("http://neo4j:password@localhost:7474/db/data")
如果 err != nil {
报错(err)
}
}
// map[lastName:PATRUS UserId:7f7014f9-bd59-4739-8e1b-5aebfa00f4c5 firstName:LARISSA]
获取账户() []账户 {
语句 := MATCH (account:Account) RETURN account.UserId, account.firstName, account.lastName
var 账户们 []账户
// 构建查询
cq := neoism.CypherQuery{
语句: 语句,
结果: &账户们,
}
// 执行查询
错误 := 数据库.Cypher(&cq)
报错(错误)
返回 账户们
}
在函数之前使用上面的账户结构体，然后在内部创建一个变量，并使用指针将其用于neoism数据库的响应。
英文:
package models
import (
"errors"
"strconv"
"time"
// "fmt"
"github.com/jmcvetta/neoism"
)
var (
Accounts map[string]*Account
)
var (
db *neoism.Database
)
func panicErr(err error) {
if err != nil {
panic(err)
}
}
type Account struct {
UserId string `json:"account.UserId"`
FirstName string `json:"account.firstName"`
LastName string `json:"account.lastName"`
}
func init() {
var err error
db, err = neoism.Connect("http://neo4j:password@localhost:7474/db/data")
if err != nil {
panic(err)
}
}
// map[lastName:PATRUS UserId:7f7014f9-bd59-4739-8e1b-5aebfa00f4c5 firstName:LARISSA]
func GetAccounts() []Account {
stmt := `
MATCH (account:Account) RETURN account.UserId, account.firstName, account.lastName
`
var accounts []Account
// construct query
cq := neoism.CypherQuery{
Statement: stmt,
Result: &accounts,
}
// execute query
err := db.Cypher(&cq)
panicErr(err)
return accounts
}
need to use the Account struct above the function and then make a variable inside and use pointer to var for the response of neoism db.
