ruby-on-rails - Ruby on Rails Form_for 错误

Question

我正在用 Ruby on Rails 制作一个游戏作为学校项目，但现在我遇到了这个错误:

#<#:0x007ff34cca8f68> 的未定义方法“storylines_index_path”

我正在制作一个页面，您希望在其中添加一个表单来添加故事情节，因此我需要一个包含一些字段的表单。我想使用 form_for 方法。但是在添加时出现此错误

这是我的代码:

views/new.html.erb

<% provide(:title, 'Overzicht Storylines') %> 
<h1>Voeg nieuwe storyline toe</h1>
<%= form_for(@storyline) do |f| %>
  <%= render 'shared/error_messages' %>

  <%= f.label :title %>
  <%= f.text_field :title%>

  <%= f.submit "Create my account", class: "btn btn-large btn-primary" %>

<% end %>

storylines_controller.rb

class StorylinesController < ApplicationController   def index
  @storylines = Storylines.find(:all)   end

  def show
    @storyline = Storylines.find(params[:id])   
  end

  def new
    @storyline = Storylines.new   end end

故事情节.rb

class Storylines < ActiveRecord::Base   
  attr_accessible :title, :text
end

路线.rb

StoryLine::Application.routes.draw do   
  get "users/new"   
  get "storylines/new"

  resources :users
  resources :storylines
  resources :sessions, only: [:new, :create, :destroy]

  match '/signup',  to: 'users#new'
  match '/signin',  to: 'sessions#new'
  match '/signout', to: 'sessions#destroy', via: :delete

  root to: 'static_pages#home'

  match '/help',    to: 'static_pages#help'
  match '/contact', to: 'static_pages#contact'
  match '/about', to: 'static_pages#contact'
  match '/home', to: 'static_pages#home'

end

Rails 约定要求您以单数形式命名您的模型，即 Storyline 而不是 Storylines。在类定义和 Controller 中重命名您的模型名称应该可以解决此问题。
