RUby在軌道上，如果其他語法混淆

有問題，如果其他 - 我想這是一個語法問題，但我似乎無法得到它。我使用了下面的建議，它仍然拋出500錯誤。我不知道確切的錯誤，因爲存在自定義錯誤消息，「500」是唯一給出的技術信息。有沒有一個調試模式，我可以在開發端提供額外的信息？RUby在軌道上，如果其他語法混淆

我想要做的是顯示一個下拉菜單，並允許選擇，如果你是一個「DSD」，否則下拉應該被禁用，這就是爲什麼我需要IF語句。

這是當前的聲明，如果我運行：

更新

 <% 
      if (sign_on.acctypw1.strip =="DS") 
       select_tag(:distributor_number_X, options_for_select(distributors_array), {:style => "width:400px", :disabled => "true"}) 
      else (sign_on.acctypw1.strip =="DSD")    
       select_tag(:distributor_number_X, options_for_select(distributors_array), {:style => "width:400px" }) 
      end 
     %>

這裏是從服務器日誌中的錯誤：你想用elsif

你離開了一個O您的第一個'options_for_select' – Huy 2013-03-22 16:02:00

什麼是500錯誤？ – 2013-03-22 19:00:33

@bobkendall當你可以發佈錯誤時，它會有所幫助。 :) – 2013-03-22 21:14:47

而不是在那裏。

您還需要來包裝你if/elsif/end在<% %>標籤，因爲這是ERB

進行了更改，現在得到一個500 – 2013-03-22 18:41:48

我改變了代碼塊以下，我仍然得到上面<％如果（sign_on.acctypw1.strip ==「DS」）％> \t \t \t \t <％= select_tag（：distributor_number_X，options_for_select（distributors_array），{：式=> 「寬度：400像素」，是：停用=> 「真」}）％> \t \t \t \t <％ELSIF（sign_on.acctypw1。條== 「REP」）％> \t \t \t \t <％= select_tag（：distributor_number_X，options_for_select（distributors_array），{：式=> 「寬度：400像素」，是：停用=> 「假」}）％> \t \t \t \t <% end %> – 2013-03-29 15:01:18

我想這是你的看法（erb.html文件）你是否和else語句也有裏面去<% %>。

<% if sign_on.acctypw1.strip =="DS" %> 
    <%= select_tag(:distributor_number_X, options_for_select(distributors_array), {:style => "width:400px", :disabled => "true"}) %> 
<% else sign_on.acctypw1.strip =="DSD" %>    
    <%= select_tag(:distributor_number_X, options_for_select(distributors_array), {:style => "width:400px" }) %> 
<% end %>

此外，東西要記住 -

<% "This will be evaluated" %> 
<%= "This will be evaluated and outputted to your view" %>

這似乎是最高效的，但仍然失敗asa 500 – 2013-03-22 20:15:37

你能告訴我們錯誤是什麼嗎？ – Catfish 2013-03-22 22:50:19

不，他們有一個自定義錯誤頁面捕捉錯誤，只顯示它是一個500是否存在並擴展錯誤模式，我可以啓用？ – 2013-03-25 12:01:14
