在数组中对对象进行分组的最有效方法是什么？

例如,给定此对象数组:

[ 
    { Phase: "Phase 1", Step: "Step 1", Task: "Task 1", Value: "5" },
    { Phase: "Phase 1", Step: "Step 1", Task: "Task 2", Value: "10" },
    { Phase: "Phase 1", Step: "Step 2", Task: "Task 1", Value: "15" },
    { Phase: "Phase 1", Step: "Step 2", Task: "Task 2", Value: "20" },
    { Phase: "Phase 2", Step: "Step 1", Task: "Task 1", Value: "25" },
    { Phase: "Phase 2", Step: "Step 1", Task: "Task 2", Value: "30" …

我用这个叫保存:

console.log(this.model.isNew());
console.log(this.model);

this.model.save({}, {
    success: function (model, response, options) {
        console.log(response);
    },
    error: function (model, xhr, options) {
        console.log(xhr.result.Errors);
    }   
});

在isNew()返回false.但是输出this.model的ID为0.(this.model.id也是0)

我的网址是 url: ROOTAREA + "/Expenses/Entry/",

更新工作正常,并按预期使用PUT.

编辑:这是我的模型的一部分:

   defaults: function () {
        return {
            DocumentDate: "",
            JobNo_: "",
            PhaseCode: "",
            WorkTypeCode: "",
            Description: "",
            Quantity: 0,
            UnitCost: 0,
            ExpenseCurrencyCode: "",
            ReimbursementCurrencyCode: "",
            UnitofMeasureCode: "DIEM",
            LineNo_: 0
        };
    },
    idAttribute: "LineNo_",

我正在尝试遵循本指南,该指南经常被引用为Cocos2d-x的优秀教程.

问题是我对Cocos2d-x(2.2和3.0 alpha0)的下载不包括教程指示的文件install-templates-xcode.sh.

知道这里发生了什么吗？我搜索了那个词,没有出现任何内容,所以我假设它没有隐藏在文件中更深层次.

出于沮丧,我下载了cocos2d-iphone,该文件夹显然有install-templates.sh文件.我宁愿为多平台开发,但这个简单的问题真的让我烦恼.我只是希望能够创建一个Xcode项目并选择cocos2d-x模板(如上面链接的教程中所示).

请参阅github存储库:

的Cocos2D-X

的Cocos2D-iPhone

请注意,iPhone存储库具有install-templates文件.

也许我错过了一些明显的东西,通常就是这种情况.无论如何,非常感谢帮助.

I've looked around and tried many different methods, but can't seem to pass actual data to my controller's function.

Here is some code:

        var URL = "/Timesheet/Timesheet/UpdateEntry";

        var dataObject = { 'newWeekEntry': newEntry, 'oldWeekEntry': oldEntry };

        alert(JSON.stringify(dataObject));

        $.ajax({
            url: URL,
            type: 'PUT',    
            data: JSON.stringify(dataObject),
            dataType: 'json',
            success: function(result) {
                alert("success?");
            }
        });

newEntry and oldEntry are both objects.

The alert line outputs this (with some properties removed, just for brevity):

{"newWeekEntry":{"MondayHours":2,"TuesdayHours":2,"WednesdayHours":5,"ThursdayHours":5,"FridayHours":"4","SaturdayHours":0,"SundayHours":0},"oldWeekEntry":{"MondayHours":2,"TuesdayHours":2,"WednesdayHours":5,"ThursdayHours":5,"FridayHours":2,"SaturdayHours":0,"SundayHours":0}}

When I debug my controller action ("UpdateEntry"), the two …

从本质上讲,我希望每个分组都有单独的行数.我相信我应该使用RowNumber.这似乎已经讨论过了,但由于我的groupby不是字符串常量,所以我遇到了困难.

我的尝试导致了类似于:

=RowNumber(Parameters!GroupBy1.Value)

如果我按原样设置,则不会加载SSRS报告.

每个DS工作的行数.如果相反我使用:

=RowNumber("NameOfMyDataSet")

我将成功进行行计数,但不会重置每组.

如果我使用变量分组名称,如何重置每组的行数？

我在ECS中尝试启动任务定义时收到错误:

CannotPullContainerError: failed to register layer: devmapper: Thin Pool has 4405 free data blocks which is less than minimum required 4480 free data blocks. Create more free space in thin pool or use dm.min_free_space option to change behavior

我发现这篇文章有一些推荐步骤,但运行这些并不能解决问题.

这是我收到的信息 docker info

试图使用Backbone的导航属性.

 this.navigate("week/" + companyName + "/" + employeeNo + "/" + weekEnd, { trigger: true, replace: false });

上面的代码执行一次.

它击中了这个:

routes: {
    "week/:companyName/:employeeNo/:weekEnd": "getWeek"
},

然后这个函数被击中两次:

getWeek: function (companyName, employeeNo, weekEnd) {
    console.log('getWeek:', companyName, employeeNo, weekEnd);
 }

它在Firefox中记录两次,在IE和Chrome中只记录一次.

这是什么问题？我原本甚至没有将触发器设置为true,并且Firefox忽略了它并仍然触发了URL.

我正在按照本指南使用Gatsby部署到S3存储桶。

如果我跑aws s3 ls mybucketname.com，

我得到了我上传的单个文件： 2019-02-15 15:53:58 477 favicon-16x16.png

但是，如果我跑步npm run deploy，

我收到此错误：

> gatsby-plugin-s3 deploy

? Failed.
AccessDenied: Access Denied

这是我中的相关代码gatsby-config.js：

plugins: [
{
     resolve: `gatsby-plugin-s3`,
     options: {
         bucketName: 'mybucketname.com'
     },
 },

这是我在AWS中创建的用户所附的IAM策略：

{
"Version": "2012-10-17",
"Statement": [
    {
        "Sid": "ListObjectsInBucket",
        "Effect": "Allow",
        "Action": [
            "s3:ListBucket"
        ],
        "Resource": [
            "arn:aws:s3:::mybucketname.com"
        ]
    },
    {
        "Sid": "AllObjectActions",
        "Effect": "Allow",
        "Action": "s3:*Object",
        "Resource": [
            "arn:aws:s3:::mybucketname.com/*"
        ]
    }
]
}

还有其他可以确定该错误来源的东西吗？

这真让我讨厌.在Objective-C中,我有一个Item具有布尔属性的实体Deleted.我希望能够将值设置Deleted为YES或1.

这是我的代码:

NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
NSEntityDescription *entity = [NSEntityDescription entityForName:@"Item" inManagedObjectContext:managedObjectContext];
[fetchRequest setEntity:entity];

NSString *itemID = [[fetchedObjects objectAtIndex:(int)[currentTable selectedRow]] valueForKey:@"ItemID"];
NSPredicate *predicate = [NSPredicate predicateWithFormat:@"ItemID = %@", itemID];
[fetchRequest setPredicate:predicate];

NSError *error = nil;
Item *objectToDelete = [[managedObjectContext executeFetchRequest:fetchRequest error:&error] objectAtIndex:0];
if (objectToDelete == nil) {
    NSLog(@"ERROR");
}

[fetchRequest release];

[objectToDelete setValue:[NSNumber numberWithBool:YES] forKey:@"Deleted"];

[managedObjectContext save:&error];

需要注意的是,我能够成功地改变不同的属性; 例如:我字符串-del添加到的末尾Item的属性Code和Name.当我查看数据表时,这些值的字符串会相应更新,但值Deleted仍为0.

axios我在维护应用程序调用之间的会话状态时遇到问题NodeJS。这是相关代码：

const express = require("express")
const cors = require("cors")
const app = express()
const initialize = require("@helpers/initialize")
const { PORT } = require("@config")

app.use(function(req, res, next) {
  res.header('Access-Control-Allow-Origin', 'http://localhost:3001');
  res.header('Access-Control-Allow-Credentials', true);
  res.header('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept');
  next();
})

app.use(cors({
    origin: ['http://localhost:3001'],
    methods: ['GET', 'POST'],
    credentials: true
}))

app.listen(PORT, () => console.log(`> App listening on port ${PORT}!`))

initialize()

我的helpers/initialize.js功能基本上被剥离以进行故障排除：

const axios = require("axios")
const {
    CS_API,
    CS_COMMANDS: { LOGIN }
} = require("@config")

module.exports = () …
