如何在Golang AppEngine中创建子实体?

I'm attempting to create a Child entity based on the docs here: https://cloud.google.com/appengine/docs/standard/python/datastore/entities

When I intiate the user instance, I'm getting an error "issing ',' in argument list" even though there is only one agument.

When I attempt to assign the parent value to Prospect on initiation, I get this error:
expected '==', found '='

func sign(w http.ResponseWriter, r *http.Request) {  
    c := appengine.NewContext(r)  
    zip, err := strconv.Atoi(r.FormValue("zip"))  

    //user := user.Current(c)  
    user = Client(name: "Bryan")   
    // error thrown "missing ',' in argument list"

    p = Prospect(parent=user )
    // error thrown: expected '==', found '='  
    p := Prospect{  
        Name:  r.FormValue("name"),  
        Zip:  zip,  
        Date:  time.Now(),  
    }  

It looks just like the examples in the documentation, what am I doing wrong?

我正在尝试根据以下文档创建子实体: https://cloud.google.com/appengine/docs/standard/python/datastore/entities

启动用户实例时,即使只有一个参数,也会出现“在参数列表中“ issing','”错误。 < p>当我尝试在启动时将父值分配给Prospect时,出现以下错误:
预期的'==',发现了'='

  func  sign(w http.ResponseWriter,r * http.Request){
c:= appengine.NewContext(r)
 zip,err:= strconv.Atoi(r.FormValue(“ zip”))
 
 // 用户:= user.Current(c)
用户=客户端(名称:“布莱恩”)
 //错误抛出“在参数列表中缺少','” 
 
p =期望(父=用户)
 /  /引发错误:预期为'==',发现为'='
p:=预期{
名称:r.FormValue(“ name”),
 邮编:zip,
日期:time.Now(),
} 
   
 
 

看起来像文档中的示例一样,我在做什么错呢?

    When using the App Engine docs and writing in Go, you constantly get redirected to the Python docs. It is the most annoying thing on the planet. Always check the URL you are at after navigation and clicking links. If you are in the right place, you should find "go" in the URL somewhere. If it shows python or java, replace it with go in the URL and hope it exists.

    So the page you really want is this: https://cloud.google.com/appengine/docs/standard/go/datastore/entities
