rails 创建元素失败，参数数量错误（给定 1，预期 0）
rails create element fail with wrong number of arguments (given 1, expected 0)
我最近在做一个"old"rails项目
我 运行 bundle install 给我 arror json 1.8.0 然后用 bundle update 和 bundle install
修复它
然后运行rake db:schema:load
而当我 运行 rake db:seed 给出错误时：
ArgumentError: wrong number of arguments (given 1, expected 0)
我删除了 seeds.rb 的所有行，只放了一个创建失败并出现相同的错误
同时打开一个控制台（rails 控制台）并尝试使用不同的模型创建两次但失败了
irb(main):002:0> Group.create( name: "Test" )
(0.5ms) BEGIN
(0.2ms) ROLLBACK
ArgumentError: wrong number of arguments (given 1, expected 0)

根据@max 评论的解决方案是：
- 更改 Gemfile 中的 rails 版本
从 gem 'rails', '4.2.0.beta2' 到 gem 'rails', '4.2.7'
- 运行
bundle update rails
问题解决了！
