Question

我更新流星0.7到0.8，铁路由器0.6.2到0.7.0并添加了火焰布局0.2.2。

以前我有使用两个参数的路径。剥离到它看起来像这样的基本部分：

{{#each users}}                                                                                                                                                                          
   <a href="{{pathFor 'template' _id=this._id fooParam=foo}}">link text</a>
{{/each}}

更新后，pathFor仅返回模板的url，没有对params进行任何操作。我还可以显示变量，一切都正确显示：

{{#each users}}
   {{this._id}} {{!displayed correctly in browser}}  
   {{foo}}      {{!displayed correctly in browser}}                                                                                                                            
   <a href="{{pathFor 'template' _id=this._id foo_param=foo}}">link text</a>
{{/each}}

如果我只是尝试使用带有_id set的数据上下文，那么结果没有变化：

{{#each users}}                                                                                                                            
   <a href="{{pathFor 'template'}}">link text</a>
{{/each}}

任何想法都将不胜感激！

Answer 1

来自iron-router的{{1}}回复：

{{pathFor}}和{{urlFor}}仍然适用于一些api更改：


{{pathFor'routeName'params = this query =“key = value＆amp; key2 = value2”hash =“somehash”anotherparam =“anothervalue”}}

{{urlFor}}
相同

根据History.md（第41-47行）中的评论：

 /**
 * Example Use:
 *
 *  {{pathFor 'items' params=this}}
 *  {{pathFor 'items' id=5 query="view=all" hash="somehash"}}
 *  {{pathFor route='items' id=5 query="view=all" hash="somehash"}}
 */

换句话说，您的pathFor帮助器需要如下所示：

<a href="{{pathFor 'template' _id=this._id query="foo_param=foo"}}">link text</a>

希望有所帮助。

fletch是正确的，因为我昨天修复了同样的事情。见https://github.com/EventedMind/iron-router/issues/580#issuecomment-39526280。

对于每个路径，我在浏览器控制台中收到以下错误：

我刚将{{pathFor'items'this}}更改为{{pathFor'items'params = this}}

在Blaze升级后，pathFor参数不再有效
