Question

我有這種形式的用戶輸入

<%= form_for @user, :html => {:name=>"new_user", :method => :post, :onclick => "return validate(this);", :multipart => true} do |form| %> 

    <fieldset> 
     <div class="field"> 
     <%= form.label :first_name %> 
     <%= form.text_field :fist_name %> 
     </div> 

     <div class="field"> 
     <%= form.label :last_name %> 
     <%= form.text_field :last_name %> 
     </div> 

     <div class="field"> 
     <%= form.label :email %> 
     <%= form.text_field :email %> 
     </div> 

     <div class="field"> 
     <%= form.label :password %> 
     <%= form.password_field :password %> 
     </div> 

     <div class="field"> 
     <%= form.label :confirm_password %> 
     <%= form.password_field :password_confirmation %> 
     </div> 

     <div class="field"> 
     <%= form.label :country %> 
     <%= form.select :country, User::COUNTRY, :prompt => 'Select your country' %> 
     </div> 

     <div class="field"> 
     <%= form.label :country_code %> 
     <%= form.text_field :code, :size=>10 %> 
     </div> 


     <div class="field"> 
     <%= form.label :phone_No %> 
     <%= form.text_field :phone, :size=>50 %> 
     </div>   

     <div class="actions"> 
     <%= form.submit 'Submit'%>     
     </div>   
    </fieldset> 
    <% end %>
