流星，铁：路由器在Router.go上传递多个属性 [英] Meteor, Iron:Router Passing Multiple Properties on Router.go

问题描述

我的困境是我想将多个对象属性传递给Meteor中的iron：router路由。原因是我想向其传递一个属性来命名我的url和一个属性来查找一个集合项。它们彼此完全独立，我不能使用url属性，因为它不是收集项中的值。这就是我所拥有的：

My dilemma is that I would like to pass multiple object properties to an iron:router route in Meteor. The reasoning is that I would like to pass it a property to name my url with and a property to find a collection item with. They are completely independent of each other and I can't use the url property because it is not a value in the collection item. This is what I have:

Template.items.events({
'click': function () {
    itemName = this.name.replace(/ /g,'')
    Router.go('itemDetails', {itemName: itemName})
    }
});

问题是，尽管路由器可以处理此问题并将其发送到正确的网址，但我无法使用 itemName 来查找我正在寻找的收集项对象（假设这是不可能的）。

The problem is that although the Router handles this fine and sends me to the correct url, I cannot use itemName to find the collection item object that I am looking for (assume this is impossible).

Router.route('/items/:itemName', {
    name: 'itemDetails', 
    data: function() {return Items.findOne({name: this.params.itemName})}
});

上述路由器配置不会返回任何内容，因为 name！= this.params .itemName 用于任何对象。

The above Router configuration will not return anything because name != this.params.itemName for any object.

我尝试传递 this 对象，或创建具有多个属性的对象，但iron：router不会没有它。

I've tried passing the this object, or creating objects with multiple properties, but iron:router won't have it.

感谢您的帮助。

编辑＃1：为了进一步说明问题，我的问题与路由到使用URL中多个ID的页面相同。例如，如何将属性传递给iron：router以填充：_ id 和：itemId 属性？

Edit #1: To help explain the question further, my problem is the same as routing to a page that uses multiple id's in the URL. For example, how would I go about passing properties to iron:router to fill the :_id and :itemId properties?

Router.route('items/:_id/:_itemId', {
    name: 'detailDetails',
    data: function() {...}
});

编辑＃2：我要具体做的是将两个属性传递给iron：router并具有其中一个附加到URL，另一个用于路由的data属性以返回收集项。例如：

Edit #2: What I would like to do specifically is pass two properties to iron:router and have one of them be appended to the URL, and the other be used in the data property of the route to return a collection item. Example:

....
    Router.go('itemDetails', {_id: itemBeingPassedId, itemName: nameToBeAppendedToURL})
....

Router.route('/items/:itemName', {
    name: 'itemDetails',
    data: function(){return Items.findOne(_id)
});

每当我尝试这样做时，它都会说 _id 未定义。因此，基本上，如何将属性传递给 data 而不将其作为URL的一部分并使用 this.params ？

Whenever I try to do that, it says that _id is undefined. So basically, how can I pass a property to data without having it be a part of the URL and using this.params?

推荐答案

问题是如何将多个参数传递给Router.go？只需将它们全部放入第二个参数的对象中即可：

Is the question how to pass multiple parameters to Router.go? Just put all of them in the object for the second parameter:

Router.go('itemDetails', {_id: 'foo', '_itemId': bar});

编辑：

好吧，如果您要将任意值传递给url，可以使用查询参数：

Ok, if you want to pass arbitrary values to the url, you can use query paramters:

Router.go('itemDetails', {itemName: 'foo'}, {query: 'id=bar'});

该ID仍将保留在URL中，如下所示：

The id will still be in the url though, it will look like this:

http://example.com/items/foo?id=bar

您可以像这样检索它：

Router.route('/items/:itemName', {
    name: 'itemDetails',
    data: function(){
        return {
            item: Items.findOne(this.params.query.id),
            itemName: this.params.itemName
        };
    }
);
