导轨中缺少模板错误

Question

new.html是注册表单，它会创建导师帐户。 它涉及错误处理。 _error_messages.html.erb是处理错误的文件，就像填写所有文本字段一样。 例如，示出了： '

The form contains 3 errors. 

    Name can't be blank 
    Password confirmation can't be blank 
    Password confirmation doesn't match Password 

然而，当没有在new.html任何输入提交表单，它示出了错误

Answer 1

当您提交表单，请求发送给create行动：

def create 
    @tutor = Tutor.new(tutor_params) 
    if @tutor.save 
     # if @tutor valid save it and redirect to show action 
     redirect_to @tutor 
    else 
     # else render the register template(or action) 
     render 'register' 
    end 
    end 

在create动作有一个条件if，在一切都很好，@tutor已经保存和Rails呼叫重定向到显示第一案行动，否则Rails试图render注册模板不存在（错误声称它）​​。要解决该问题，请创建register模板，并选择所需的html代码，如果@tutor未保存，则该代码应运行。
