javascript - 如何使用云代码和 Shashido 在按钮单击时更改解析 Angular 色数组？

Question

如果单击该函数并且我必须在云代码中对其进行编码，我需要将数组的值从“User”更改为“Admin”。

但是有一个问题，数组没有改变

以下代码可以工作，但只有 nameRoleQuery 的部分不起作用，这就是我需要更改的部分。

promoteToAdmin: function promoteToAdmin(request, response) {
    if (!request.params.companyUser) {
        response.error('Request did not have an authenticated user attached with it');
    } else {
        var companyUser;
        var companyUserQuery = new Parse.Query('CompanyUser');
        companyUserQuery.include('user');
        companyUserQuery.include('company');
        companyUserQuery.get(request.params.companyUser, {
            useMasterKey: true
        }).then((giveRolename) => {
                        var nameRoleQuery = new Parse.Query(Parse.Role);
                        request.nameRoleQuery.set('user', ['Admin']);
                        return nameRoleQuery.save(null, {
                            useMasterKey: true
                        });
                    }).then((companyUserObject) => {
            companyUser = companyUserObject;
            var userRoleQuery = new Parse.Query(Parse.Role);
            userRoleQuery.equalTo('name', 'Company-User-' + companyUser.get('company').id);
            return userRoleQuery.first({
                useMasterKey: true
            });
        }).then((userRole) => {
            var usersInUserRole = userRole.relation('users');
            usersInUserRole.remove(companyUser.get('user'));
            return userRole.save(null, {
                useMasterKey: true
            });
        }).then((userRoleSaveResult) => {
            var adminRoleQuery = new Parse.Query(Parse.Role);
            adminRoleQuery.equalTo('name', 'Company-Admin-' + companyUser.get('company').id);
            return adminRoleQuery.first({
                useMasterKey: true
            });
        }).then((adminRole) => {
            var usersInAdminRole = adminRole.relation('users');
            usersInAdminRole.add(companyUser.get('user'));
            return adminRole.save(null,{
                useMasterKey: true
            });
                    }).then((saveResult) => {
                        console.log('after');
            response.success('fissa is aan');
        }, (error) => {
            console.log(error);
        });
                    console.log();
    }

}

Angular 色数组需要更改。

仍然不确定你到底想做什么，但这就是我想你想要发生的事情。

CompanyUser 有一个名为“user”、类型为 Parse.User 的指针。当您运行此查询时，您希望根据您的图像更新此 Parse.User。以下内容应该有效:

        //AS ABOVE
             .then((giveRolename) => {
                  var user = giveRoleName.get("user");
                  user.remove('role','user');
                  user.add('role','admin');
                  return user.save(null, {useMasterKey:true});
           }).then((companyUserObject) => {
//companyUserObject is Parse.User object. If CompanyUser object is needed, store in variable beforehand. 

我在下面列出了我对当前代码的改进建议。它的顺序性较差，并且在流程中间发生错误时提供了更大的后备。它没有箭头功能，因此您必须进行相应的更改。

function promoteToAdmin(request, response) {

    var params = request.params;
    var companyUserId = params["companyUser"];

    var companyUser;

    return Parse.Promise.as().then(
        function()
        {
            if(!companyUser)
            {
                return Parse.Promise.error("Request did not have an user attached with it.");
            }
            var CompanyUser = Parse.Object.extend("CompanyUser");
            var companyUserQuery = new Parse.Query(CompanyUser);
            companyUserQuery.include("user");
            companyUserQuery.include("company");
            return companyUserQuery.get(companyUserId,{useMasterKey:true});

        }
    ).then(
        function(fetchedCompanyUser)
        {
            companyUser = fetchedCompanyUser;
            var company = companyUser.get("company");

            var userRoleQuery = new Parse.Query(Parse.Role);
            userRoleQuery.equalTo('name', "Company-User-" + company.id )

            var adminRoleQuery = new Parse.Query(Parse.Role);
            adminRoleQuery.equalTo('name', "Company-Admin-" + company.id);


            return Parse.Promise.when(
                userRoleQuery.first({useMasterKey:true}),
                adminRoleQuery.first({useMasterKey:true})
            )

        }
    ).then(
        function(userRole,adminRole)
        {
            if(!userRole || !adminRole)
            {
                return Parse.Promise.error("No role found")
            }

            var user = companyUser.get("user");

            user.remove("role","user");
            user.add("role","admin");

            userRole.getUsers().remove(user);
            adminRole.getUsers().add(user);


            return Parse.Promise.when(
                user.save(null,{useMasterKey:true}),
                userRole.save(null,{useMasterKey:true}),
                adminRole.save(null,{useMasterKey:true})
            )

        }
    ).then(
        function(user,userRole,adminRole)
        {
            response.success("success");
        },
        function(error)
        {
            response.error(error);
        }
    )

}
