格式错误：在表格第一个参数不能包含零或为空

Question

我下面这个教程设置与条纹设计集成：http://www.jaredrader.com/blog/2013/12/18/a-stripe-integration

我已经成功设立的条纹详细情况和创建的各种控制器，模型和观点。

然而，形式创造一个ArgumentError in Users::Registrations#new

这里的错误代码：

ArgumentError in Users::Registrations#new 
    Showing /home/action/workspace/mediadb/app/views/devise/registrations/new.html.erb where line #62 raised: 

    First argument in form cannot contain nil or be empty 

形式：

<div class="panel panel-default"> 
    <div class="panel-heading"> 
<% if params[:plan] == "2" %> 
<h1>Sign up with premium!</h1> 
    </div> 

    <div class="panel-body"> 
<%= form_for(resource, :as => resource_name, :url => registration_path(resource_name)) do |f| %> 
    <%= devise_error_messages! %> 

    <%= hidden_field_tag 'plan', params[:plan] %> 

    <div class="form-group"> 
     <%= f.label :name %> 
     <%= f.text_field :name, autofocus: true, class: "form-control" %> 
    </div> 

    <div class="form-group"> 
     <%= f.label :email %> 
     <%= f.email_field :email, class: "form-control" %> 
    </div> 

    <div class="form-group"> 
     <%= f.label :password %> 
     <%= f.password_field :password, class: "form-control" %> 
    </div> 

    <div class="form-group"> 
     <%= f.label :password_confirmation %> 
     <%= f.password_field :password_confirmation, class: "form-control" %> 
    </div> 

    <h2>Payment</h2> 

    <%= f.hidden_field :stripe_card_token %> 
     <div class="form-group"> 
     <%= label_tag :card_number, "Credit Card Number" %> 
     <%= text_field_tag :card_number, nil, name: nil, class: "form-control" %> 
     </div> 
     <div class="form-group"> 
     <%= label_tag :card_code, "Security Code on Card (CVV)" %> 
     <%= text_field_tag :card_code, nil, name: nil, class: "form-control" %> 
     </div> 
     <div class="form-group"> 
     <%= label_tag :card_month, "Card Expiration" %> 
     <%= select_month nil, {add_month_numbers: true}, {name: nil, id: "card_month"}%> 
     <%= select_year nil, {start_year: Date.today.year, end_year: Date.today.year+15}, {name: nil, id: "card_year"}%> 
     </div> 
     <div id="stripe_error"> 
     <noscript>JavaScript is not enabled and is required for this form. First enable it in your web browser settings.</noscript> 
     </div> 

    <div class="form-group"> 
     <%= f.submit "Sign up", class: "btn btn-lg btn-success" %> 
    </div> 
    <% end %> 
    </div> 
<% else %> 
    <h1>Sign up for free</h1> 
    </div> 
    <div class="panel-body"> 
    <%= form_for(resource, :as => resource_name, :url => registration_path(resource_name), html: { id: "free_plan"}) do |f| %> 
     <%= devise_error_messages! %> 

     <%= hidden_field_tag 'plan', params[:plan] %> 

     <div class="form-group"> 
      <%= f.label :name %> 
      <%= f.text_field :name, autofocus: true, class: "form-control" %> 
     </div> 

     <div class="form-group"> 
      <%= f.label :email %> 
      <%= f.email_field :email, class: "form-control" %> 
     </div> 

     <div class="form-group"> 
      <%= f.label :password %> 
      <%= f.password_field :password, class: "form-control" %> 
     </div> 

     <div class="form-group"> 
      <%= f.label :password_confirmation %> 
      <%= f.password_field :password_confirmation, class: "form-control" %> 
     </div> 

     <div class="form-group"> 
      <%= f.submit "Sign up", class: "btn btn-lg btn-primary" %> 
     </div> 
     <% end %> 
    <% end %> 
    </div> 
</div> 

的routes.rb中文件：

Rails.application.routes.draw do 
    resources :lists 
    resources :publications 
    resources :contacts 

    devise_for :users, controllers: { registrations: 'users/registrations' } 

    devise_scope :user do 
    get '/sign_up', to: 'users/registrations#new', as: :sign_up 
    get '/sign_in', to: 'devise/sessions#new', as: :sign_in 
    get '/:id/edit', to: 'users/registrations#edit', as: :edit 
    put 'users/update_plan', :to => 'users/registrations#update_plan' 
    put 'users/cancel_plan', :to => 'users/registrations#cancel_plan' 
    end 

    resources :users, only: [:index, :show] 



    # root should always be last 
    root to: 'pages#home' 
end 

注册控制器：

class Users::RegistrationsController < Devise::RegistrationsController 

    def new 
    unless (params[:plan] == '1' || params[:plan] == '2') 
     flash[:notice] = "Please select a plan to sign up." 
     redirect_to root_url 
    end 
    end 

    def update_plan 
    @user = current_user 
    @user.update_attributes(plan_id: params[:plan], email: params[:email], stripe_card_token: params[:user][:stripe_card_token]) 
     if @user.plan_id == 2 
     @user.save_with_payment 
     redirect_to edit_user_registration_path, notice: "Updated to premium!" 
     else 
     flash[:error] = "Unable to update plan." 
     render :edit 
     end 
    end 

    def cancel_plan 
    @user = current_user 
    if @user.cancel_user_plan(params[:customer]) 
     @user.update_attributes(stripe_customer_token: nil, plan_id: 1) 
     flash[:notice] = "Canceled subscription." 
     redirect_to edit_user_registration_path 
    else 
     flash[:error] = "There was an error canceling your subscription. Please notify us." 
     render :edit 
    end 
    end 

    private 

    def build_resource(*args) 
    super 
    if params[:plan] 
     resource.plan_id = params[:plan] 
     if resource.plan_id == 2 
     resource.save_with_payment 
     else 
     resource.save 
     end 
    end 
    end 

    def setup 
    plans = Plan.all 
    plans.each do |plan| 
     unless plan.id == 1 
     @startup_plan = plan 
     end 
    end 
    end 
end 

任何想法有什么不对？

Answer 1

更新Users::RegistrationsController#new如下

def new 
    if (params[:plan] == '1' || params[:plan] == '2') 
    super 
    else 
    flash[:notice] = "Please select a plan to sign up." 
    redirect_to root_url 
    end 
end
