我刚创建了一个新的Rails API应用程序,我试图第一次运行它。 我安装了foreman gem,我正在使用命令
foreman start
启动服务器,但我收到了这些错误:

我已尝试更新gemset并重新设置终端等。
然而没有任何效果。想知道是否有人可以就如何继续诊断此错误来源提出想法
由于
EDIT 以下是ApplicationController.rb的内容
class ApplicationController < ActionController::API
include ActionController::MimeResponds
include ActionController::ImplicitRender
end
的Gemfile:
source 'https://rubygems.org'
gem 'rails', '3.2.8'
gem 'rails-api'
gem 'pg'
gem 'thin'
gem 'foreman'
gem 'rabl'
gem "paperclip"
gem 'aws-sdk'
group :development do
gem 'annotate', :git=>'git://github.com/ctran/annotate_models.git'
gem 'debugger'
end
错误指向此文件中的第8行:wrap_parameters.rb
# Be sure to restart your server when you modify this file.
#
# This file contains settings for ActionController::ParamsWrapper which
# is enabled by default.
# Enable parameter wrapping for JSON. You can disable this by setting :format to an
empty array.
ActiveSupport.on_load(:action_controller) do
ERROR >>>> wrap_parameters format: [:json]
end
# Disable root element in JSON by default.
ActiveSupport.on_load(:active_record) do
self.include_root_in_json = false
end
答案 0 :(得分:9)
wrap_parameters中的问题在rails-api的0.0.3版本中得到修复,但是对于以前生成的应用程序,我们必须用initializers / wrap_parameters.rb中的第一个代码块替换这个:
ActiveSupport.on_load(:action_controller) do
include ActionController::ParamsWrapper
wrap_parameters format: [:json] if respond_to?(:wrap_parameters)
end
我现在已经在我的一个heroku应用程序中对它进行了测试并且运行良好。无需再重写全功能轨道中的代码:)

您的Rails项目目录的根目录中是否有Procfile
?对于最简单的设置,我的Procfiles通常如下所示:
web: bundle exec thin start -p $PORT
(当然,你的Gemfile中也需要gem 'thin'
。)
