Question

在我的验证中没有显示错误消息不正确的保存数据显示错误消息，而不是显示错误消息，

 Missing template employees/create, application/create with {:locale=>[:en], :formats=>[:html], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :jbuilder]}

我的模特是，

  validates :emp_firstname, :presence=> {:message=>" cannot be blank"},
             :format => { :with => /\A[a-zA-Z@\.\s]*\z/, :message => "only alphabets."}
validates :emp_lastname, :presence=> {:message=>" cannot be blank"},
             :format => { :with => /\A[a-zA-Z@\.\s]*\z/, :message => "only alphabets."}
validates :address
validates :email_id, :presence=> {:message => "cannot be blank."},
             :format => { :with =>  /\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\Z/i, :message => "Give Correct format"}

我的观看页面是，

    <% if @employee.errors.any? %>
    <div id="error_explanation">
        <h2>
            <%= pluralize(@employee.errors.count, "error") %> Errors
        </h2>
        <ul>
            <% @employee.errors.full_messages.each do |message| %>
                <li>
                    <%= message %>
                </li>
            <% end %>
        </ul>
    </div>
<% end %>
<table align="center">
    <tr>
        <td>Firstname<span class="required"></span></td>
        <td><%= f.text_field :emp_firstname, :required => true%></td>
    </tr>
    <tr>
        <td>Lastname<span class="required"></span></td>
        <td><%= f.text_field :emp_lastname, :required => true %></td>
    </tr>
    <tr>
        <td>Address<span class="required"></span></td>
        <td><%= f.text_area :address, :required => true %></td>
    </tr>
    <tr>
        <td>Email_id<span class="required"></span></td>
        <td><%= f.text_field :email_id, :required => true%></td>
    </tr>

controller create method，

 def create
   @employee = Employee.new
   @employee.emp_firstname = params[:employee][:emp_firstname]
   @employee.emp_lastname = params[:employee][:emp_lastname]
   @employee.address = params[:employee][:address]
   @employee.email_id = params[:employee][:email_id]
   @employee.comp_id = params[:company][:comp_id]
   @employee.dom_id = params[:domain][:dom_id]
     if @employee.save
       respond_to do |format|
               format.html {flash[:notice] = 'Employee was successfully created.' and redirect_to action: "index"}   
       end
     end
 end

保存新员工时，不会显示验证错误消息。显示模板缺失错误。当我在现场提供正确的格式时，会保存员工的详细信息。请给我正确的方法来显示验证错误消息谢谢。

更新用
在验证之前，邮件是错误的，因此它会回滚。

Parameters: {"utf8"=>"✓", "authenticity_token"=>"2w/EyPI1+MGacWDXfX7fIE6VC5uDMlD9vbho+gXra1LD7U3XOzhLHoV5XSLmWwG5QY8tw9bOgMggMrt1/netdQ==", "employee"=>{"emp_firstname"=>"Aishwarya", "emp_lastname"=>"Prabha", "address"=>"xxxxxxx", "email_id"=>"dsfdsf"}, "company"=>{"comp_id"=>"1"}, "domain"=>{"dom_id"=>"3"}, "commit"=>"Save"}(0.2ms) BEGIN(0.2ms) ROLLBACK

更正邮件后，也会回滚。没有保存。

Parameters: {"utf8"=>"✓", "authenticity_token"=>"zxMM4m0F+aSejV+8UMk3gv3M3H2ueBz7xCppMEEQNqvX8YX9pAhKe4GFYknL7Okb8tb6JfuEzM5ZoLq/uozwjA==", "employee"=>{"emp_firstname"=>"Aishwarya", "emp_lastname"=>"Prabha", "address"=>"xxxxxxx", "email_id"=>"example@mail.com"}, "company"=>{"comp_id"=>""}, "domain"=>{"dom_id"=>""}, "commit"=>"Save"}(0.1ms)BEGIN(0.1ms)ROLLBACK

我的表格中有下拉列表不起作用。所以com_id和dom_id变空了。

如果成功保存对象而没有任何验证错误，您将重定向到索引操作，但如果出现错误怎么办？

您还应该处理错误情况，以便如果对象未保存，则应该呈现新表单，其中显示错误消息。

根据您的错误代码，它正在搜索不存在的创建视图文件，因此您应该明确声明

渲染'新' //在其他情况下检查此行

class EmployeesController < ApplicationController

def create
    @employee = Employee.new
    @employee.emp_firstname = params[:employee][:emp_firstname]
    @employee.emp_lastname = params[:employee][:emp_lastname]
    @employee.address = params[:employee][:address]
    @employee.email_id = params[:employee][:email_id]
    @employee.comp_id = params[:company][:comp_id]
    @employee.dom_id = params[:domain][:dom_id]
      if @employee.save
        respond_to do |format|
                format.html {flash[:notice] = 'Employee was successfully created.' and redirect_to action: "index"}   
        end
      else
        render 'new' // This will show your error messages

      end
end

结束

因此，如果对象的验证失败，它将呈现为新操作，然后将显示验证消息。

ruby on rails验证未显示错误消息
