Question

当我尝试提交空白表单时，我会收到以下验证错误消息：

Start time time Looks like you forgot the appointment start time.
Start time time Sorry, we can't understand "" as a time.
Start time ymd Please choose a date for the appointment.
Start time ymd Sorry, we can't understand "" as a date.
Stylist services Please choose at least one service.

这些消息适用于以下属性：

start_time_time
start_time_time
start_time_ymd
start_time_ymd
stylist_services

我包含了属性名称，因此您可以清楚地看到错误消息的哪一部分是属性名称。

如何从错误消息中删除属性名称？

Answer 1

在rails 3.2.6中，您可以通过在语言环境文件（例如，config / locales / en.yml）中设置errors.format来抑制包含属性名称：

en:
  errors:
    format: "%{message}"

否则，默认格式为＆＃34;％{attribute}％{message}＆＃34;。

Answer 2

循环object.full_messages以输出每条完整的消息是很常见的：

<% if object.errors.any? %>
  <h2>Errors</h2>
  <ul>
  <% object.errors.full_messages.each do |msg| %>
    <li><%= msg %></li>
  <% end %>
  </ul>
<% end %>

<h2>Errors</h2>
<ul>
  <li>Start time time Looks like you forgot the appointment start time.</li>
  <li>Start time time Sorry, we can't understand "" as a time.</li>
  <li>Start time ymd Please choose a date for the appointment.</li>
  <li>Start time ymd Sorry, we can't understand "" as a date.</li>
  <li>Stylist services Please choose at least one service.</li>
</ul>

但是“完整”消息包含本地化字段名称后跟消息（正如您所见;这是因为消息通常是“不能为空”）。如果您只想要实际的错误消息减去字段名称，请使用内置的each迭代器：

<% if object.errors.any? %>
  <h2>Errors</h2>
  <ul>
  <% object.errors.each do |field, msg| %>
    <li><%= msg %></li>
  <% end %>
  </ul>
<% end %>

<h2>Errors</h2>
<ul>
  <li>Looks like you forgot the appointment start time.</li>
  <li>Sorry, we can't understand "" as a time.</li>
  <li>Please choose a date for the appointment.</li>
  <li>Sorry, we can't understand "" as a date.</li>
  <li>Please choose at least one service.</li>
</ul>

Answer 3

您可以使用i18n路线更改属性的显示名称。

配置/区域设置/ en.yml：

en:
  activerecord:
    attributes:
      somemodel:
        start_time_time: My Start Time Text  #renamed text
        stylist_services: "" #hidden txet

Answer 4

我做的几乎和布兰登一样。

首先，我为错误将呈现的对象编写了一个辅助函数。

#Remove unnecessary attribute names in error messages
def exclude_att(attribute, error_msg)
  if attribute.to_s == "Put attribute name you don't want to see here"
    error_msg
  else
    attribute.to_s.humanize + " " + error_msg
  end
end

然后，在具有验证形式的视图中，我做了：（注意：这是HAML代码而不是HTML，但标签仍然相同，所以你可以清楚地看到我在做什么）

%h3= "#{pluralize(@user.errors.count, 'error')} prohibited this user from being saved:"
  %ul
   - @user.errors.each do |att, error|
     %li= exclude_att(att, error)

这对我来说，没有宝石或第三方插件。
