ngResource保存（）的奇怪行为 [英] ngResource save() strange behaviour

问题描述

有人请阐明这一些轻？

Can someone please shed some light on this?

var discountResource = $resource(GLOBALS.apiPath + 'discounts/:id');
var discountResponse = discountResource.save($scope.discountForm);

这会导致一个GET到/折扣

This results in a GET to /discounts

然而这会导致一个POST /折扣（预期的行为）

However this results in a POST to /discounts (expected behaviour)

var discountResource = $resource(GLOBALS.apiPath + 'discounts');
var discountResponse = discountResource.save($scope.discountForm);

我对此很坚持，因为我想用第一个选项，以声明的占位符。但对我的生活，我不能得到它的工作。

I'm very stuck on this, as I would like to use the first option, with the placeholder declared. But for the life of me I cannot get it to work.

我要选择1的原因是这样我就可以在工厂decalre并注入资源进入我的控制器。基本上我不希望每次我需要一个API互动时间重新声明它。我希望是有道理的。

The reason I want option 1 is so that I can decalre it in a factory and inject the resource into my Controllers. Basically i don't want to redeclare it every time I need an API interaction. I hope that makes sense.

推荐答案

尝试这样的事情

 Module.factory("Discount", ["$resource", function ($resource) { return $resource(GLOBALS.apiPath + "discounts/:Id", { Id: "@Id" }, {
            somthingCustomIfNeeded: { method: 'POST', url: GLOBALS.apiPath + "something-custom" }
        }); }]);

注意 {ID：@Id} 对象吗？它告诉角度如何解决：id变量

Notice the { Id: "@Id" } object? It tells Angular how to resolve that :Id variable

从文档报价

如果该参数值是与@ pfixed然后该参数的值将从数据对象相应的属性来提取$ P $（设置调用操作方法时）。例如，如果该defaultParam对象是{someParam：'@someProp'}然后someParam的值将是data.someProp

If the parameter value is prefixed with @ then the value for that parameter will be extracted from the corresponding property on the data object (provided when calling an action method). For example, if the defaultParam object is {someParam: '@someProp'} then the value of someParam will be data.someProp
