Question

ruby中有没有办法绕过application.html.erb但是仍然使用控制器的相应视图？

现在我有

render :layout => false

但我从视图中收到以下错误：

undefined method `each' for nil:NilClass

以下是我目前的帖子控制器：

class PostsController < ApplicationController
  def index
    @posts = Post.where('is_deleted' => false, 'is_hidden' => false).limit(15).order('created_at DESC')
  end 
  def show
    @posts = Post.find(params[:id], :conditions => 'is_deleted = false')
  end 
  def page
    render :layout => false
    @posts = Post.where('is_deleted' => false, 'is_hidden' => false).limit(15).offset(params[:page].to_i * 15).order('created_at DESC')
  end 
end

Answer 1

def page
  render :layout => false
  @posts = Post.where('is_deleted' => false, 'is_hidden' => false).limit(15).offset(params[:page].to_i * 15).order('created_at DESC')
 end

应该是

def page
  @posts = Post.where('is_deleted' => false, 'is_hidden' => false).limit(15).offset(params[:page].to_i * 15).order('created_at DESC')
  render :layout => false
end

渲染布局false但仍加载视图
