在顶部 <div> 中显示 simple_form 错误消息 [英] Displaying simple_form error messages in top &lt;div&gt;

问题描述

我有以下两个_forms:

用户表单

<%= simple_form_for(@user, :url => @target) do |f|％＞<% if @user.errors.any?％＞<div id="error_explanation"><h2><%=pluralize(@user.errors.count, "error") %>禁止保存此用户:</h2><ul><% @user.errors.full_messages.each do |msg|％＞<li><%=msg%></li><%结束%>

<%结束%><%= f.input :email, :label =>用户电子邮件"%><%= f.input :password, :label =>用户密码"%><%= f.input :first_name %><%= f.input :last_name %><%= f.button :submit %><%结束%>

租户表格

<%= simple_form_for(@tenant, :url => @target) do |f|％＞<% if @tenant.errors.any?％＞<div id="error_explanation"><h2><%=pluralize(@tenant.errors.count, "error") %>禁止保存此租户:</h2><ul><% @tenant.errors.full_messages.each do |msg|％＞<li><%=msg%></li><%结束%>

<%结束%><%= f.input :name, :label =>'名称', :required =>真%><%= f.input :billing_email, :label =>'电子邮件', :required =>真%><%= f.input :country, :label =>'国家', :required =>真%><%= f.button :submit %><%结束%>

我从 stackoverflow 看到以下帖子 Rails 3.0 中的 f.error_messages

这里有一个方法，可以通过使用 f.error_messages 从简单的表单返回错误消息，但我一直无法让它工作，因为我不确定这个方法应该保存在哪里.有人有任何提示吗?方法如下:

class StandardBuilder  "title-error")错误列表< "error-recap round-border")结尾结尾

解决方案

只需将 error: false 添加到您的输入中，这不会清除 css，但会清除内联错误

f.input error: false 或 :error =>错误的

来自 http://ruby.railstutorial.org/book/ruby-on-rails-tutorial

/app/views/shared/_error_messages.html.erb

 <% if object.errors.any?％＞<div id="error_explanation"><div class="alert alert-error">表单包含 <%=pluralize(object.errors.count, "error") %>.

<ul><% object.errors.full_messages.each do |msg|％＞<li>* <%= msg%></li><%结束%>

<%结束%>

在视图中

<%= form_for(@user) do |f|％＞<%= render 'shared/error_messages', object: f.object %><%= f.label :name %><%= f.text_field :name %><%= f.label :email %><%= f.text_field :email %><%= f.label :password %><%= f.password_field :password %><%= f.label :password_confirmation, "Confirmation" %><%= f.password_field :password_confirmation %><%= f.submit 创建我的账户"，类别:btn btn-large btn-primary"%><%结束%>

I have the following two _forms:

user form

<%= simple_form_for(@user, :url => @target) do |f| %>
  <% if @user.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@user.errors.count, "error") %> prohibited this user from being saved:</h2>
      <ul>
      <% @user.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  <%= f.input :email, :label => "User Email" %>
  <%= f.input :password, :label => "User Password" %>
  <%= f.input :first_name %>
  <%= f.input :last_name %>
  <%= f.button :submit %>
<% end %>

tenant form

<%= simple_form_for(@tenant, :url => @target) do |f| %>
  <% if @tenant.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@tenant.errors.count, "error") %> prohibited this tenant from being saved:</h2>

      <ul>
      <% @tenant.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  <%= f.input :name, :label => 'Name', :required => true %>
  <%= f.input :billing_email, :label => 'Email', :required => true %>
  <%= f.input :country, :label => 'Country', :required => true %>
  <%= f.button :submit %>
<% end %>

I have come across the following post from stackoverflow f.error_messages in Rails 3.0

Here there is method so that error messages can be returned from the simple form by using f.error_messages but I have been unable to get this working as I am unsure whereabout this method should be saved. Anyone got any hints? The method is as follows:

class StandardBuilder < ActionView::Helpers::FormBuilder
  def error_messages
    return unless object.respond_to?(:errors) && object.errors.any?

    errors_list = ""
    errors_list << @template.content_tag(:span, "There are errors!", :class => "title-error")
    errors_list << object.errors.full_messages.map { |message| @template.content_tag(:li, message) }.join("\n")

    @template.content_tag(:ul, errors_list.html_safe, :class => "error-recap round-border")
  end
end

解决方案

Just add error: false to your inputs this will not clear the css but will clear the inline errors

f.input error: false or :error => false

Edit:

From http://ruby.railstutorial.org/book/ruby-on-rails-tutorial

/app/views/shared/_error_messages.html.erb

 <% if object.errors.any? %>
  <div id="error_explanation">
   <div class="alert alert-error">
     The form contains <%= pluralize(object.errors.count, "error") %>.
   </div>
  <ul>
   <% object.errors.full_messages.each do |msg| %>
    <li>* <%= msg %></li>
   <% end %>
 </ul>
</div>
<% end %>

in VIEW

<%= form_for(@user) do |f| %>
  <%= render 'shared/error_messages', object: f.object %>

  <%= f.label :name %>
  <%= f.text_field :name %>

  <%= f.label :email %>
  <%= f.text_field :email %>

  <%= f.label :password %>
  <%= f.password_field :password %>

  <%= f.label :password_confirmation, "Confirmation" %>
  <%= f.password_field :password_confirmation %>

  <%= f.submit "Create my account", class: "btn btn-large btn-primary" %>
<% end %>
