如何使.liquid文件在Rails 3中工作

我正在使用Rails 3.0.9。 我试图使用液体，我收到一个错误。

这是我的Gemfile

source 'http://rubygems.org' gem 'rails', '3.0.9' gem 'sqlite3' gem 'liquid' 

这是一个初始化程序

 class LiquidView PROTECTED_ASSIGNS = %w( template_root response _session template_class action_name request_origin session template _response url _request _cookies variables_added _flash params _headers request cookies ignore_missing_templates flash _params logger before_filter_chain_aborted headers ) PROTECTED_INSTANCE_VARIABLES = %w( @_request @controller @_first_render @_memoized__pick_template @view_paths @helpers @assigns_added @template @_render_stack @template_format @assigns ) def self.call(template) "LiquidView.new(self).render(template, local_assigns)" end def initialize(view) @view = view end def render(template, local_assigns = nil) @view.controller.headers["Content-Type"] ||= 'text/html; charset=utf-8' # Rails 2.2 Template has source, but not locals if template.respond_to?(:source) && !template.respond_to?(:locals) assigns = (@view.instance_variables - PROTECTED_INSTANCE_VARIABLES).inject({}) do |hash, ivar| hash[ivar[1..-1]] = @view.instance_variable_get(ivar) hash end else assigns = @view.assigns.reject{ |k,v| PROTECTED_ASSIGNS.include?(k) } end source = template.respond_to?(:source) ? template.source : template local_assigns = (template.respond_to?(:locals) ? template.locals : local_assigns) || {} if content_for_layout = @view.instance_variable_get("@content_for_layout") assigns['content_for_layout'] = content_for_layout end assigns.merge!(local_assigns.stringify_keys) liquid = Liquid::Template.parse(source) liquid.render(assigns, :filters => [@view.controller.master_helper_module], :registers => {:action_view => @view, :controller => @view.controller}) end def compilable? false end end ::ActionView::Template.register_template_handler(:liquid, LiquidView) 

这是app / views / users / index.html.liquid

 
Listing users
  {% for user in @users %}  {% endfor %} 
 
 
Name
 
 
 {{ user.name }} 
  

这是控制器

 class UsersController < ApplicationController def index @users = User.all respond_to do |format| format.html # index.html.erb end end end 

我收到了这个错误。

 undefined method `template' for # Extracted source (around line #1): 1: 
Listing users
 2: 3:  4:

 我认为这应该可以帮助您，只需使用下面的代码更改初始化程序 
 class LiquidView def self.call(template) "LiquidView.new(self).render(#{template.source.inspect}, local_assigns)" end def initialize(view) @view = view end def render(template, local_assigns = {}) @view.controller.headers["Content-Type"] ||= 'text/html; charset=utf-8' assigns = @view.assigns if @view.content_for?(:layout) assigns["content_for_layout"] = @view.content_for(:layout) end assigns.merge!(local_assigns.stringify_keys) controller = @view.controller filters = if controller.respond_to?(:liquid_filters, true) controller.send(:liquid_filters) elsif controller.respond_to?(:master_helper_module) [controller.master_helper_module] else [controller._helpers] end liquid = Liquid::Template.parse(template) liquid.render(assigns, :filters => filters, :registers => {:action_view => @view, :controller => @view.controller}) end def compilable? false end end ActionView::Template.register_template_handler :liquid, LiquidView 
 只是不要忘记将liquid_methods [，：column_name]放到模型中
