ruby-on-rails - 使用正则表达式 ruby 验证电话号码

Question

我正在尝试验证电话号码是否为数字:-

这是我的user.rg

 number_regex = /\d[0-9]\)*\z/


 validates_format_of :phone, :with =>  number_regex, :message => "Only positive number without spaces are allowed"

这是我的view.html.haml

%li
   %strong=f.label :phone, "Phone Number"
   =f.text_field :phone, :placeholder => "Your phone number"

这是 Controller

def edit_profile
        @user = current_user
        request.method.inspect
        if request.method == "POST"
            if @user.update_attributes(params[:user])
                sign_in(@user, :bypass => true)
                flash[:success] = "You have updated your profile successfully"
                redirect_to dashboard_index_path
            else
                flash[:error] = "Profile could not be updated"
                render :action => "edit_profile"
            end
        end  
    end

当我第一次在文本字段中输入数字时，它会正确验证，但是如果我输入正确的格式，然后尝试输入错误的格式，则会跳过验证，并且会收到一条闪存消息，表明配置文件已成功更新，但是错误的值(带字母)未保存。

这可能是什么问题？

Answer 1

我用这个，:with =>“没问题”。

validates :phone,:presence => true,
                 :numericality => true,
                 :length => { :minimum => 10, :maximum => 15 }

如果您想要消息 (不是MASSAGE)，请尝试以下操作，

 validates :phone,   :presence => {:message => 'hello world, bad operation!'},
                     :numericality => true,
                     :length => { :minimum => 10, :maximum => 15 }

还要检查 this问题。
