Rails3 ActionView 模板处理程序在生产服务器上不起作用 [英] Rails3 ActionView Template Handlers doesn't work on Production Server

问题描述

我使用的是 Rails 3.2.3/Ruby 1.9.3p125/jbuilder (0.4.0)

I am using Rails 3.2.3 / Ruby 1.9.3p125 / jbuilder (0.4.0)

在我的 view/mycontroller 文件夹中，我有一个 show.json.jbuilder 文件.当我使用 rails s -e production 在本地机器上测试所有内容时，一切正常.JSON 按预期呈现.

In my view/mycontroller folder i got a show.json.jbuilder file. when I test everything on my local machine with rails s -e production everything works fine. The JSON gets rendered as espected.

但是当我部署到 Ubuntu LTS (nginx/unicorn) 时，我收到以下错误消息:

But when I deploy to Ubuntu LTS (nginx/unicorn) I get the following Error Message:

ActionView::MissingTemplate (Missing template mycontroller/show, application/show with {:locale=>[:de, :en], :formats=>[:json], :handlers=>[:erb, :builder]}. Searched in:
  * "/home/deployer/apps/myapp/releases/#############/app/views"
):

当我在服务器上检查 jbuilder gem 是否与 bundle show jbuilder 一起安装时，一切似乎都正确.

When I check on my server if the jbuilder gem is installed with bundle show jbuilder everything seems right.

奇怪的是错误消息没有显示 :handlers=>[:erb, :builder, :jbuilder]显然缺少 jbuilder 处理程序.但是我该如何解决这个问题?

weird is that the Error message does't show :handlers=>[:erb, :builder, :jbuilder] The jbuilder handler is obviously missing. But how do I solve the problem?

问题不是基于 Jbuilder.我试过 rabl 也出现同样的问题.

The Problem is not based on Jbuilder. I tried rabl and the same problem appears.

有没有人有提示，如何调试?

Does any one has a hint, how to debug this?

这里有更多信息:

宝石文件

source 'https://rubygems.org'

gem 'rails', '3.2.3'
gem 'jquery-rails'
gem 'mysql2'
gem 'simple_form'

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'
  gem 'uglifier', '>= 1.0.3'
  gem 'bootstrap-sass', '2.0.2'
end

# Use unicorn as the app server
gem 'unicorn'

# Deploy with Capistrano
gem 'capistrano'

# for performance monitoring
gem 'newrelic_rpm'

# use asset pipline and flash
gem 'swf_fu', '~> 2.0'

gem 'geocoder'

# To use Jbuilder templates for JSON
gem 'jbuilder'

控制器

  def show

  end

show.json.jbuilder - 文件

show.json.jbuilder - file

 json.(@map, :id)

推荐答案

您的 jbuilder 似乎被跳过了.

Your jbuilder seems to be skipped.

jbuilder 是否在您的 Gemfile.lock 文件中?

Is jbuilder in your Gemfile.lock file?

cat Gemfile.lock | grep jbuilder

如果丢失:

RAILS_ENV=production bundle update jbuilder 

jbuilder 可以加载吗?

Is jbuilder loadable?

RAILS_ENV=production bundle exec rails console
> require 'jbuilder'
=> false  # this is false if jbuilder is pre-loaded

你能在控制台中构建吗?

Can you build in the console?

> Jbuilder.encode{|j| j.foo :bar }
=> "{\"foo\":\"bar\"}"

你能在你的控制器动作中构建吗?

Can you build in your controller action?

def the_method_you_are_testing
   raise Jbuilder.encode{|j| j.foo :bar }
end

您是否在不同的服务器设置中看到相同的错误，例如 Apache &乘客而不是 Nginx &独角兽，还是简单的 Rails 服务器?

Do you see the same error with a different server setup, such as Apache & Passenger instead of Nginx & Unicorn, or simply rails server?

rails server -e production

如果您将服务器应用从生产改为开发，您会得到相同的结果吗?

Do you get the same results if you change your server app from production to development?

rails server -e development

对于 RABL，您可以尝试将 RABL gem 最后 放在您的 Gemfile 中吗?

For RABL, can you try putting the RABL gem last in your Gemfile?

gem 'rails'
#...
gem 'rabl'

在需要构建器后立即尝试注册?

Try registering immediately after requiring builder?

require 'tilt'
require 'rabl'
# ...
require 'builder'
Rabl.register!

使用 RABL master 得到相同的结果吗?

Do you get the same results with RABL master?

gem 'rabl', :git => "git://github.com/nesquena/rabl.git"
