Question

我有这个表格，我试图将表格的内容提交给模特＆＃34; Leeds＆＃34;然后根据数据是否通过模型验证显示成功/失败消息。

我遇到的问题是当我点击＆＃34;发送消息＆＃34;按钮，它从Root到Root/leeds。

这是我使用的形式：

<%= form_for @leed, {url:root_path, html: {id:"contactForm", name:"sentMessage", novalidate:true}} do |leed| %>
    <div class="row">
            <div class="col-md-6">
                <!-- Name -->
                <div class="form-group">
                    <%= leed.text_field :name, class: "form-control", :placeholder => "Your name *", :required => true, :data => {:validation_required_message => 'Please enter your name.' }  %>
                    <p class="help-block text-danger"></p>
                </div>
                <!-- Email -->
                <div class="form-group">
                    <%= leed.email_field :email, class: "form-control", :placeholder => "Your email *", :required => true, :data => {:validation_required_message => 'Please enter your email address.' } %>
                    <p class="help-block text-danger"></p>
                </div>
                <!-- Phone -->
                <div class="form-group">
                    <%= leed.telephone_field :phone, class: "form-control", :placeholder => "Your phone *", :required => true, :data => {:validation_required_message => 'Please enter your phone number.' } %>
                    <p class="help-block text-danger"></p>
                </div>
            </div>
            <!-- Message -->
            <div class="col-md-6">
                <div class="form-group">
                    <%= leed.text_area :message, class: "form-control", :placeholder => "Your message *", :required => true, :data => {:validation_required_message => 'Please enter a message.' } %>
                    <p class="help-block text-danger"></p>
                </div>
            </div>
            <div class="clearfix"></div>
            <!-- Submit -->
            <div class="col-lg-12 text-center">
                <div id="success">
                    <%= render 'shared/error_messages' %>
                </div>
                <%= button_tag "Send Message", class: "btn btn-xl" %>
            </div>

    </div>
<% end %>

这是我的routes.rb：

Rails.application.routes.draw do
  root 'home#index'
  post "/" => 'home#create'
end

这是我的HomeController方法：

  def create
    @leed = Leed.new(leed_params)
    if @leed.save
      #update page to reflect success
      flash[:success] = "Thank you, we'll contact you as soon as possible"
    else
      #update page to flect failure
      flash[:danger] = "There was an issue with the login attempt #{@leed.errors.full_messages.inspect}"
    end
    # redirect_to thank_you.html.erb
    render nothing:true
  end

Answer 1

在#create方法的最后，您有render nothing: true。这意味着帖子请求将被提交给/ lead，但是服务器不会告诉浏览器去其他地方，所以浏览器将保留在/ lead url。如果您希望在完成发布请求后将浏览器重定向到其他页面，则可以在创建操作结束时添加重定向。希望有所帮助！

Answer 2

Puhlze是对的，您应该能够将页面重定向到Flash消息应该显示的位置。您还可以创建remote: true表单并创建一个create.js.erb文件，该文件将弹出通知消息而无需重新呈现页面;这是我们在使用AJAX提交时通常会做的事情。

无法在按钮提交时显示闪烁或错误消息
