如何将对象从块辅助程序传递到块状流星中? [英] How to pass an object from to a block helper back to the block in meteor blaze?

问题描述

在流星0.8引起轰动之前，我能够将对象传递给自定义块帮助器内容，如下所示:

Before Meteor 0.8, that brought blaze, I was able to pass objects to a custom block helper content like this:

return options.fn(object)

现在，大放异彩的是，阻止助手需要返回这样的模板.

Now that with blaze, block helpers require to return a template something like this.

return Template.someTemplate

如何实现旧的行为.我想要的是以下内容:

How can I achieve the old behaviour. What I want to to is the following:

我使用了一个blockhelper

I use a blockhelper

{{#blockhelper argument="something"}}
   {{somePartOfTheObject}}
{{/blockhelper}}

然后在blockhelper定义中，我想根据参数做一些事情，这将返回一个对象.

Then in the the blockhelper definition, I want to do some stuff based on the argument, that will return an object.

UI.registerhelper "blockhelper", () ->
   object = getStuffFrom(this.argument)
   return Template.someTemplate(object)

根据需要，我创建了一个最小的模板

As needed by blaze I created a minimal template

<template name="someTemplate">
    {{> UI.contentBlock}}
</template>

Now blaze现在不允许将对象传递到此模板，因此可以在块内容中使用它.

Now blaze does not allow to pass an object to this template, so it can be used within the block contents.

我该如何解决?

我知道流星将是在控制器中获取对象.但是，由于我想将其用于原型框架，所以我希望能够直接从blockhelper创建一个或多个上述对象，以便有人可以传递将被转换为对象的精子.

I know the meteor-way would be to get the object in the controller. But as I want to use this for a prototyping framework, I want to be able to create said object or objects directly from the blockhelper, so someone can pass argmuents that will get converted to objects.

推荐答案

该解决方案非常简单.

如果我有助手:

UI.registerhelper "blockhelper", () ->
   object = getStuffFrom(this.argument)
   return Template.someTemplate

帮助程序的变量和对象实际上在模板中可用.因此，您只需这样做:

The variables and object of the helper are actually available in the template. So you simply do:

<template name="someTemplate">
    {{> UI.contentBlock object}}
</template>
