Question

我尝试从包含三个参数的表单中验证并保存电子邮件：name，：email和：message，然后发送整个电子邮件。目前，电子邮件将成功发送，无需验证参数或创建电子邮件实例。

控制器

def thank_you
    @name = params[:name]
    @email = params[:email]
    @message = params[:message] || "Hello!"

    if Email.create(name: @name, email: @email, message: @message)

      ActionMailer::Base.mail(
          :from => @email, 
            :to => 'erikvdw@comcast.net', 
            :subject => "A new contact form message from #{@name}", 
            :body => @message).deliver
    end
  end

模型

class Email < ActiveRecord::Base
  validates_presence_of :name
  validates_format_of :email, :with => /\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\z/i
  validates_length_of :message, :maximum => 500, :minimum => 10
end

查看

<%= form_tag("/thank_you") do %>
                  <div class="row">
                    <div class="col-md-5">
                      <div class="input-group">
                          <%= text_field_tag :name, nil, class: 'form-control', placeholder: 'Your Name' %>
                      </div>
                    </div>
                    <div class="col-md-7">
                      <div class="input-group">
                        <span class="input-group-addon" id="basic-addon1">@</span>
                        <%= text_field_tag :email, nil, class: 'form-control', placeholder: 'Your Email Address' %>
                      </div>
                    </div>
                  </div>
                  <br>
                  <div class="row">
                    <div class="col-md-12">
                      <div class="input-group text-area-wide">
                        <%= text_area_tag :message, nil, class: 'form-control text-area-wide', placeholder: 'When are you available?' %>
                      </div>
                    </div>
                  </div>
                  <br>
                  <%= submit_tag 'Get Started', class: 'btn btn-success' %>
                  <p><a href="http://www.skype.com/en/" target="_blank">Skype</a> required</p>
                <% end %>

我认为你在操作中的问题

＆＃13;

Email.create

＆＃13;

因为它在内存中创建了一个实例而没有将实例保存到数据库中。您必须直接调用save方法或检查验证方法 - email.valid？，如下所示：

＆＃13;

 email = Email.create(name: @name, email: @email, message: @message)
if email.valid?
  #send email
end

＆＃13;

无法在控制器中创建对象实例
