Question

您好我正在尝试使用Rails form_for帮助程序来创建新表单。我已经为表单提供了一个新模型，但是它一直试图使用错误的路由来引发异常的动作attr。当我明确定义动作ex (url: {action: 'create'})

时，它确实有效

class Person < ActiveRecord::Base
end

class PeopleController < ApplicationController
    def new
        @person = Person.new
    end
end

这是在我的配置/路由文件中：

resources :people

这就是我在视图中所做的事情（即使用HAML）

= form_for(@person) do |f|
    = f.label :name
    = f.text_field :name
    = f.submit

，抛出的异常是

未定义的方法`people_index_path'

之前我曾经使用它（使用erb和早期版本的rails），所以我不确定它们是怎么回事。非常感谢任何帮助！

Rake路线看起来像这样：

people      GET    /people(.:format)          people#index
            POST   /people(.:format)          people#create
new_person  GET    /people/new(.:format)      people#new
edit_person GET    /people/:id/edit(.:format) people#edit
 person     GET    /people/:id(.:format)      people#show
            PATCH  /people/:id(.:format)      people#update
            PUT    /people/:id(.:format)      people#update
            DELETE /people/:id(.:format)      people#destroy

这是服务器日志中的报告

Rails 4.0.2 form_for帮助程序使用错误的路由？
