である私のusers_controller

def create  
    @user = User.new(params[:user]) 
    if @user.save! 
     clear_current_session 
     MailAgent.registration_confirmation(@user).deliver 
     flash[:notice] = 'Please activate your account by clicking on the link sent to you by email.' 
     redirect_to new_user_url 
    else 
     flash.now[:error] = 'Please fix the listed errors' 
     render 'new' 
    end 
    end 

に作成されています。上部に最も近い線は、下部にある線よりも関連性が高い。多くの行は "間違ったエラー"となり、問題ではないが、問題のために失敗する。どのようなものが適切かを理解するには、推測作業と健全な経験が必要です。

スタックトレースを含めると、さらにお手伝いできます。
