在Rails 3中使用液体 [英] Using liquid in Rails 3

问题描述

我出于学习目的制作了Rails博客引擎.我想使用液体作为模板引擎.我有这样的东西

Im making a Rails blog engine for learning purpose. I want to use liquid as template engine. I have something like this

    ## posts_controller.rb
    ...
    def index
      @posts = Post.all
    end
   ... 
    ## posts/index.html.liquid
    {% for post in posts do %}
      {{ post.title }}
    {% endfor %}

那给了我以下错误:

undefined local variable or method `template' for
#<PostsController:0x103d16290>

我已经在Initializers/liquid.rb中加载了LiquidView 请让我知道我的问题是什么. 谢谢

I already had LiquidView loaded in initializers/liquid.rb Please let me know what is my problem. Thank you

推荐答案

据我所知，您应该具有用于​​属性的液体方法(在您的情况下为"title").尝试这样的事情

As I know you should have liquid methods for attributes (in your case for 'title'). try something like this

class Post < ActiveRecord::Base
  liquid_methods :title
end

然后看看.

如果不尝试使Liquid :: Drop继承Post类

If not try to make Post class inherited by Liquid::Drop

喜欢

class Posts < Liquid::Drop

end

**顺便说一句，因为您在声明缺少模板变量时遇到错误，请确保您的液体渲染部分如下

** BTW since you get an error claiming missing template variable make sure your liquid rendering part is as follows

(直接从液态文档复制)

(directly copied from liquid doc)

@template = Liquid::Template.parse("hi {{name}}")  # Parses and compiles the template
@template.render( 'name' => 'tobi' )               # Renders the output => "hi tobi"

希望这会有所帮助
