parse-platform - Parse.com，将用户添加到创建的角色

Question

我有一个云代码，它在用户注册时创建两个帐户角色。下面是方法

Parse.Cloud.afterSave("account", function(request) {
    var accountName = request.object.get("name");

    //create admin role
    var adminRoleACL = new Parse.ACL();
    adminRoleACL.setPublicWriteAccess(true);
    var adminRole = new Parse.Role(accountName + "_Administrator", adminRoleACL);
    adminRole.save() ; 

    //create user role
    var userRoleACL = new Parse.ACL();
    userRoleACL.setPublicWriteAccess(true);
    var userRole = new Parse.Role(accountName + "_User", userRoleACL);
    userRole.save();
});

现在我想要实现的是添加刚刚注册这两个角色的用户。但不幸的是，我在云代码中看到我无法获得当前用户。所以我所做的是在从客户端创建角色后将用户添加到角色中。下面是相同的代码。代码执行正常，我没有看到任何错误，但是我没有看到用户被添加到数据浏览器中的角色。知道为什么会这样吗？我错过了什么吗？非常感谢您的所有帮助。

user.signUp(null, {
    success : function(user) {
        var currentUser = Parse.User.current();

        var accountName = account.get("name");

        var query = new Parse.Query(Parse.Role);
        query.contains("name", accountName);

        query.find({
            success : function(roles) {
                if (!roles) {
                    alert("No roles for " + accountName + " were found");
                } else {
                    for (var i = 0; i < roles.length; i++) {
                        //add the user for admin role
                        //TODO: this needs to be done only once for the account owner
                        if (roles[i].get("name").search(USER_TYPE.ADMIN) >= 0) {
                            roles[i].getUsers().add(currentUser);
                        }

                        //add the user for user role
                        if (roles[i].get("name").search(USER_TYPE.USER) >= 0) {
                            roles[i].getUsers().add(currentUser);
                        }
                        var saved = roles[i].save();
                    }
                    alert("User was added into roles");
                }
            },
            error : function(error) {
                alert("Could not add users to the account " + accountName + " error: " + error.message);
            }
        });

        alert("User created successfully");
    },
    error : function(user, error) {
        alert("Error: " + error.code + " " + error.message);
    }
});

感谢您的帮助。我通过使用这样的云代码来完成它

1. 在创建帐户时创建角色。

   Parse.Cloud.afterSave("account", function(request) {
   
       var accountName = request.object.get("name");
       //create admin role
       var adminRoleACL = new Parse.ACL();
       adminRoleACL.setPublicReadAccess(false);
       adminRoleACL.setPublicWriteAccess(false);
       var adminRole = new Parse.Role(accountName + "_Administrator", adminRoleACL);
       adminRole.save();
   
       //create user role
       var userRoleACL = new Parse.ACL();
       userRoleACL.setPublicReadAccess(false);
       userRoleACL.setPublicWriteAccess(false);
       var userRole = new Parse.Role(accountName + "_User", userRoleACL);
       userRole.save();
   });
   

2. 然后将用户添加到创建的角色

   Parse.Cloud.define("addUsersToRole", function(request, response) {
   
       Parse.Cloud.useMasterKey();
       var currentUser = request.user;
       var accountName = request.params.accountname;
       var isAdmin = request.params.admin;
   
       var query = new Parse.Query(Parse.Role);
       query.contains("name", accountName);
       query.find({
           success : function(roles) {
               console.log("roles: " + roles.length);
               for (var i = 0; i < roles.length; i++) {
   
                   if ( isAdmin = false && roles[i].get("name").search("_Administrator") >= 0)
                       continue;
   
                   roles[i].getUsers().add(currentUser);
                   roles[i].save();
               }
               response.success();
           },
           error : function(error) {
               response.error("error adding to admin role " + error);
           }
       });
   });
