私の見解では異なる確認メッセージを表示するために、この醜い重複に直面しています。

<% if current_user.password.nil? and current_user.services.count == 1 %>
  <%= link_to "Disconnect #{service.provider.capitalize}", service, :confirm => 'Remove this service will delete your account, are you sure?', :method => :delete %>
<% else %>
  <%= link_to "Disconnect #{service.provider.capitalize}", service, :confirm => 'Are you sure you want to remove this authentication option?', :method => :delete %>
<% end %>

これを回避する方法があるかどうか知りたいですか？

ありがとうございました！

実行するだけです：

<%= link_to "Disconnect #{service.provider.capitalize}", service, :confirm => current_user.password.nil? and current_user.services.count == 1 ? 'Remove this service will delete your account, are you sure?' : 'Are you sure you want to remove this authentication option?', :method => :delete, :class => "remove" %>

または、これをより理解しやすくするために：

<% confirm_message = current_user.password.nil? and current_user.services.count == 1 ? 'Remove this service will delete your account, are you sure?' : 'Are you sure you want to remove this authentication option?' %>

<%= link_to "Disconnect #{service.provider.capitalize}", service, :confirm => confirm_message, :method => :delete, :class => "remove" %>

私はRubyの三項演算子を使用しています。確認してください：http：//invisibleblocks.wordpress.com/2007/06/11/rubys-other-ternary-operator/

ヘルパー関数を作成できます。

def auth_confirm_delete(current_user)
  if current_user.password.nil? and current_user.services.count == 1
      'Remove this service will delete your account, are you sure?'
  else 
      'Are you sure you want to remove this authentication option?'
  end
end

そして、それはビューでより良く見えます:

<%= link_to "Disconnect #{service.provider.capitalize}", service, :confirm => auth_confirm_delete, :method => :delete %>
