Rails 2.3搜索表單在驗證失敗時丟失字段值

我有一個表單是搜索表單。當它無法驗證而不是保留字段值時，它們將被刪除，用戶必須重新輸入。我如何保留字段值？Rails 2.3搜索表單在驗證失敗時丟失字段值

sign_in.html.erb：

 <% form_tag(params.merge({ :action => "sign_in" }), :method => "post", :id => "sign_in_form") do %> 
      <div class="form_item_half"> 
      <%= build_field_label(:user, :username, "Username") %> 
      <%= text_field :user, :username, :class => "text" %> 
      </div> 

      <div class="form_item_half" onKeypress="return keyRestricted(event)" onKeydown="return keyRestricted(event)"> 
      <%= build_field_label(:user, :ssn_third, "Last four digits of Social Security Number") %> 
      <span id="exes">XXX-XX-</span> 
      <%= password_field :user, :ssn_third, :maxlength => "4", :class => 'text securitynum3', :autocomplete => "off" %> 
      </div> 

      <%= build_field_label(:user, :dob, 'Date of birth') %> 
      <div class="padding-bottom10 form_item_full clearfix date"> 
      <%= select_month 14, :prompt => 'Select Month' %> 
      <%= text_field :dob, :day, :size => 2, :value => 'Day', :class => 'text' %> 
      <%= text_field :dob, :year, :size => 4, :value => 'Year', :class => 'text' %> 
      <div id="date_errors"></div> 
      </div> 

      <div class="padding-bottom10 form_item_full clearfix"> 
      <%= render :partial => "/shared/captcha" %> 
      </div> 

      <div class="mp_buttons clearfix"> 
      <input type="image" class="button" name="continue" 
        src="/images/v6/buttons/btn_signinsecurely.png" title="SignIn" alt="Sign In Securely"> 
      </div> 
     <% end %>

onboarding_controller.rb：

def sign_in 
    if request.post? 
     flash[:errors] = Messages['onboarding/invalid_creds']; return unless @onboarding_user 
     flash[:errors] = Messages['onboarding/invalid_creds']; return unless params[:user][:username] == @onboarding_user.username 
     flash[:errors] = Messages['onboarding/invalid_creds']; return unless @onboarding_user.same_last_four?(params[:user][:ssn_third]) 
     flash[:errors] = Messages['general/wrong_captcha']; return unless captcha_match? 
     unless 
      Date.new(params[:dob][:year].to_i, params[:date][:month].to_i, params[:dob][:day].to_i) == @onboarding_user.dob.to_date 
     flash[:errors] = Messages['onboarding/invalid_creds'] 
     render :sign_in 
     end 
     session[:onboarding_user] = @onboarding_user 
     redirect_to :action => sign_up 
    end 
    end

如果輸入的值不匹配什麼是存儲在數據庫中的@onboarding_user，那麼我們閃錯誤消息和渲染：sign_in。但是，這並不保留字段值...

@onboarding_user裝入一個的before_filter：

before_filter :load_objects_from_params, :only => :sign_in 

    def load_objects_from_params 
    @onboarding_user = OnboardingUser.find(params[:id]) unless params[:id].blank? 
    @onboarding_user = OnboardingUser.find_by_username(params[:user][:username]) unless @onboarding_user or request.get? 
    end

這裏是由控制器看到的參數哈希：

Processing OnboardingController#sign_in (for 127.0.0.1 at 2013-06-18 09:17:17) [POST] 
    Parameters: {"authenticity_token"=>"Ij6v3x/QVZQ9pU1JPL433xMnzAJ/I4ndo+nFMCHK1Ok=", "action"=>"sign_in", "captcha_word"=>"asa", "date"=>{"month"=>"1"}, "user"=>{"username"=>"al", "ssn_third"=>"[FILTERED]"}, "continue.x"=>"-325", "continue.y"=>"-810", "controller"=>"onboarding", "dob"=>{"year"=>"12", "day"=>"1"}}

這裏的HTML這實際上得到的標籤：

<form action="/onboarding/sign_in?authenticity_token=Ij6v3x%2FQVZQ9pU1JPL433xMnzAJ%2FI4ndo%2BnFMCHK1Ok%3D&amp;captcha_word=asa&amp;continue.x=-325&amp;continue.y=-810&amp;date%5Bmonth%5D=1&amp;dob%5Bday%5D=1&amp;dob%5Byear%5D=12&amp;user%5Bssn_third%5D=3333&amp;user%5Busername%5D=al" id="sign_in_form" method="post" novalidate="novalidate">

任何想法/建議是不勝感激！提前致謝！

另外，我正在通過jQuery驗證插件進行客戶端驗證。我沒有在這裏包含代碼，因爲我認爲這不是相關的，但如果有必要，我可以提供。

實際上有兩個問題在這裏：

我並沒有呈現sign_in頁面中所有的驗證情況：

閃光燈[：錯誤] =消息[ '入職/ invalid_creds'] ;渲染：sign_in;除非@onboarding_user
sign_in.html.erb中的參數名稱必須與被驗證的對象相同。因此，例如，而不是這樣的：
「文本」％>

，我需要這樣的：

<%= text_field :onboarding_user, :username, :class => "text" %>

希望這可以幫助別人的未來！
