我一直试图弄清楚一些代码.我有一个表格,我正在尝试使用Wicked和Cocoon宝石.一切正常,包括link_to_add_association功能.我正在为Cocoon推荐的相关表单字段渲染部分,并且除了link_to_remove_association函数之外,一切似乎都在找工作.它返回以下错误:

new_record?nil的未定义方法:NilClass

这是我的部分错误:

<div class="nested-fields">
  <div>
    <%= f.input :address1 %>
  </div>
  <div>
    <%= f.input :address2 %>
  </div>
  <div>
    <%= f.input :city %>
  </div>
  <div>
    <%= f.input :state %>
  </div>
  <div>
    <%= f.input :postal %>
  </div>
  <div>
    <%= link_to_remove_association "remove task", f %>
  </div>
</div>

以下是调用partial的视图:

<%= simple_form_for @vendor, url: wizard_path do |f| %>
    <div id="locations">
      <%= f.simple_fields_for :locations do |location| %>
        <%= render 'location_fields', :f => location %>
      <% end %>
      <div class="links"> …

你可以在包含WickedWizard gem的控制器中使用非restful方法吗？

控制器:

class Books::BookUpdateController < ApplicationController

  include Wicked::Wizard
  steps :title_step,  :ai_archive_step, :ai_override_step #etc

   def show
      ...
   end

   def update
      ...
   end

   def waterfall
      ...# loads of code to set up instance variables in the view, which I don't want to have to include in the normal show action for all the wizard steps. 
   end
end

路线:

resources :book_update do     
  member do
    get 'waterfall'
    ... and others 
  end
end

gem的版本1和更低版本允许非静态操作,但是这个解决此PR的提交强制执行步骤名称.我去这条路线的错误 http://localhost:3000/book_update/3949/waterfall是

Wicked::Wizard::InvalidStepError in Books::BookUpdateController#waterfall …

好吧,所以我真的不了解邪恶的宝石中的嵌套路由.

到目前为止,我有这个.我不确定是否所有内容都在正确的文件夹中,或者我是否正确.

的routes.rb

resources :events   
resources :events do
  resources :build, controller: 'events/build' 
end

控制器/ events_controller.rb

 def create
        @event = Event.new(event_params)
        if @event.save
            flash[:success] = "Event Created!"
            redirect_to event_build_path(event_id: "event", id: @event.id) 
            # previously had redirect_to event_build_path without parameters)
        else
            render 'new'
        end
    end

控制器/活动/ build_controller.rb

class Events::BuildController < ApplicationController
    include Wicked::Wizard

    steps :details, :visibility

    def show
        @event = Event.find(params[:event_id])
        render_wizard
    end
end

意见/编译/ details.html.erb

<%= form_for @event do |f| %>
#blab blah 
<% end %>

我一开始event_build_path没有参数,我有这个错误 No route …
