用露营和哈姆渲染局部

Question

我正在尝试使用露营制作一个简单的博客，就像露营附带的示例一样，只是我想将 haml 用于视图而不是 markaby。我想使用 _post.html.haml 部分呈现帖子，但我觉得我可能会走错路。

博客.rb

require 'camping'

Camping.goes :Blog

Blogtitle = "My Blog"

module Blog
  # Path to where you want to store the templates
  set :views, File.dirname(__FILE__) + '/views'
  module Blog::Models
    class Post < Base; belongs_to :user; end
    class Comment < Base; belongs_to :user; end
    class User < Base; end
  end

  module Blog::Controllers
    class Index
      def get
        @posts = Post.find :all
        render :index
      end
    end
  end
end

views/index.html.haml

!!!
%html
%head
%meta{'http-equiv' => 'Content-Type', :content => 'text/html', :charset => 'UTF-8' }/
%title=Blogtitle
%body=render @posts

views/_post.html.haml

%h2=post.title
%p=post.html_body

错误

NoMethodError at /
undefined method `to_sym' for #<Array:0xb6e426d4>

Ruby  (eval): in lookup, line 12

Traceback (innermost first)

%body=render @posts

Answer 1

首先，要渲染一个局部，你必须这样做：

render :_post, :locals => { :post => post }

如果您想渲染所有帖子，只需使用循环：

%body
  - @posts.each do |post|
    = render :_post, :locals => { :post => post }
