Ruby on rails RubyonRails：处理未链接到模型的表单

我在实现这一点上遇到了困难。此外，我在控制器的索引页上遇到了“错误数量的参数（1代表0）”错误

routes.rb

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

  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

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

潜在候选人\u controller.rb

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

  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

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

class PotentialcandidatesController

index.html.erb

send.html.erb

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

  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

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

过程

是

ActionController:：Base

中的一种方法，您不希望在控制器中重写它

---

更改名称，更新路由和表单，并重新启动服务器；它应该可以正常工作。

索引页的其余部分是什么？您的错误来自向不接受任何参数的方法发送参数。这就是我的索引页上的全部内容，即表单的链接。您确定该错误来自索引吗？我在此处收到错误：。那不是索引页吗？啊，我现在明白了。不能将

进程

用作控制器方法。它在

ActionController:：Base

中使用。我向控制器添加了一个空的send方法，但遇到了相同的错误。

send

也是

ActionController:：Base

中的一个方法。请记住，您还需要对路由和视图进行必要的更改。谢谢它的工作！我还有第二个问题。。。我试图从一个表单中获取信息，并在名为User的模型中创建一个新记录。在调用User.create（）之后，我是否必须执行任何操作？User.create将在数据库中创建一个条目。如果您想稍后使用该信息，则必须使用ActiveRecord将该条目提取出来。
