Ruby on Rails：處理未鏈接到模型的表單

Question

我在執行此操作時遇到困難。此外，我遇到了我的控制器的索引頁上的「錯誤的參數數量（1爲0）」錯誤。

的routes.rb

resources :potentialcandidates, :only => [:index, :send, :process] 
get 'potentialcandidates/send' => 'potentialcandidates#send', :as => :send_potentialcandidate 
post 'potentialcandidates/process' => 'potentialcandidates#process', :as => :process_potentialcandidate 

potentialcandidates_controller.rb

class PotentialcandidatesController < ApplicationController 
    def index 
    end 

    def process 
    @name = params[:name] 
    @email = params[:email] 
    # Add user to user model 
    @user = User.create(email: @email, name: @name, status: "active") 
    end 
end 

index.html.erb
<a href="<%= send_potentialcandidate_path %>">Add</a>

send.html.erb

<%= form_tag process_potentialcandidate_path do %> 
     <%= text_field_tag "name" %> 
     <%= text_field_tag "email" %> 
     <%= submit_tag %> 
    <% end %>

process是ActionController::Base的方法和你不希望重寫它在你的控制器。

更改名稱，更新路由和表單，然後重新啓動服務器;它應該工作得很好。
