呈现文字但仍然丢失模板错误

Question

def r_return 

    if var 
    begin 
     User.transaction do 
     #code here 
     end 
    render :text => html 
    return 
    rescue => e 
     #rescue here 
    end 
    else 
    redirect_to root_path 
    end 
    #it has to been render at the end? 
    #render :text => html 
end 

我的代码有什么问题？无法呈现它开始...结束块？或者我失踪了？

Answer 1

这似乎是一个例外被投入开始救援块。
