Rails Simple_form在加载表单时显示表单验证错误

Question

嗯，我是rails的新手，我试图在索引动作的模态中创建一个表单，除了打开这个模态以外，我发现所有需要的输入都是红色的，令人困惑，因为我没有点击提交按钮但是检查验证，你可以在屏幕截图中看到，所以我在这里做错了什么？任何帮助表示赞赏

这是index.html.erb中的模态部分

<%= render 'popup' %>

这里是_popup.html.erb

<% content_for :popup do %>
<%- model_class = Supplier -%>
 <div class="modal splash fade" id="splash" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
  <div class="modal-content">
    <div class="modal-header">
      <h1><%= t '.title', :default => model_class.model_name.human.titleize %></h1>
    </div>
    <div class="modal-body">
      <%= render 'form' %>
    </div>           
  </div>
</div>
 </div>
 <% end %>

这是_form.htm.erb

<%= simple_form_for(@supplier ,remote: true) do |f| %> 
 <div class="form-inputs">
  <%= f.input :name %>
  <%= f.input :code %>
  <%= f.input :email , :hint => "should be a valid email "%>
  <%= f.input :status %>
  <%= f.input :total_credit %>
  <%= f.input :user_id,collection: [] || User.all ,label_method: :name , value_method: :id ,include_blank: true %>
  <%= f.input :notes %>
 </div>
 <div class="modal-footer">
   <%= f.button :submit %>
 </div>
<% end %>

和控制器动作：索引

def index
 @suppliers  = Supplier.all
 @supplier   = Supplier.new
end

这是我的模特：

class Supplier < ActiveRecord::Base

has_many :supplier_branches
has_many :supplier_phones
has_many :supplier_contacts
has_many :purchase_invoices
belongs_to :user

validates :name,:code, presence: true
validates :email, format: { with: /\A([^@\s]+)@((?:[-a-z0-9]+\.)+[a-z]{2,})\z/i, on: :create }

end
