python Flask Triangle中的语法错误

问题描述

由于我希望将AngularJS与Flask结合使用，所以我寻找了一个很好的工具来处理这些框架，因为Jinja和Angular会有彼此的问题。我发现这是非常酷，工作，但刚刚达到一定点。像这样的东西的作品，例如：

 < a ng-show =post.linkhref ={{post。链路|角}}> 
 {{post.title | angular}} 
< / a> 
  

但是另一方面，这是行不通的：

 < span> 
< a href =＃/ posts / {{$ index | angular}}>评论< / a> 
< / span> 
  

当我尝试这样做时，我收到以下错误：

我做错了什么，或者只是在这种情况下，框架是有限的吗？帮助非常感谢。

解决方案

Since I wanted to use AngularJS in combination with Flask, I searched for a cool tool to handle these frameworks properly since Jinja and Angular would have problems with each other. I found Triangle which is pretty cool and working but just up to a certain point. Stuff like this works for example:

<a ng-show="post.link" href="{{post.link|angular}}">
    {{post.title|angular}}
</a>

But on the other hand this does not work:

<span>
    <a href="#/posts/{{$index|angular}}">Comments</a>
</span>

When I try to do that, I receive following error

Am I doing something wrong or is the framework just limited in that case? Help is highly appreciated.

解决方案

As the error message is saying, $ cannot be used in Jinja as part of a variable.

Instead, you'll need to change Angular's delimiter notation:
