与RoR相对较新。使用Rails 4，Foundation，使用AJAX（remote：true）。每次提交条目时，db条目的数量都会翻倍。第一次提交生成两次，第二次提交生成4，第三次生成8，依此类推。表格是一个显示模态。当我在simple_form_for调用中删除remote：true标记时，它只添加一个条目，因此我怀疑它与此有关。我试图弄明白我已经绞尽脑汁待了2天。
这是表单（_form.html.erb）
<%= simple_form_for @applicant_address, remote: true do |f| %>
<%= f.error_notification %>
<div class="form-inputs black_label">
<%= f.hidden_field :applicant_id %>
<%= f.input :street, :label => "Street Address" %>
<%= f.input :city %>
<%= f.input :state %>
<%= f.input :zip, :label => "Zip Code" %>
<%= f.input :length_years, :label => "Years at this address" %>
<%= f.input :length_months, :label => "Months at this address" %>
</div>
<div class="form-actions">
<%= f.button :submit, :value => "Submit New Address" %>
</div>
<% end %>
这是控制器（applicant_addreses_controller.erb）：
class ApplicantAddressesController < ApplicationController
before_action :set_applicant_address, only: [:show, :edit, :update, :destroy]
# GET /applicant_addresses
# GET /applicant_addresses.json
def index
@applicant_addresses = ApplicantAddress.all
end
# GET /applicant_addresses/1
# GET /applicant_addresses/1.json
def show
end
# GET /applicant_addresses/new
def new
@applicant_address = ApplicantAddress.new(:applicant_id => params[:applicant_id])
end
# GET /applicant_addresses/1/edit
def edit
end
# POST /applicant_addresses
# POST /applicant_addresses.json
def create
@applicant_address = ApplicantAddress.new(applicant_address_params)
@applicant = @applicant_address.applicant
@applicant_address.user_id = current_user.id
respond_to do |format|
if @applicant_address.save
format.html { redirect_to applicant_path(@applicant_address.applicant_id) }
format.json { render :show, status: :created, location: @applicant_address }
format.js
else
format.html { render :new }
format.json { render json: @applicant_address.errors, status: :unprocessable_entity }
end
end
end
这是js（create.js.erb）：
/* Updating the list with the new data elements */
$("#panel2").html("<%= escape_javascript(render 'applicants/show_addresses', :applicant => @applicant) %>");
/* Activating Best In Place */
$(document).ready(function() {
jQuery(".best_in_place").best_in_place();
});
/* Closing the Modal */
$("#myModal").foundation('reveal','close')
$(document).foundation();
以下是显示数据的部分列表（_show_addresses.html.erb）：

值得注意的是......删除行完美无缺。
此外，我的文件夹中只有application.js文件，它位于assets / javascripts /文件夹中。
非常感谢任何帮助。感谢。
答案 0 :(得分：1)
验证您的application.js文件是否包含对jquery_ujs和rails_ujs的引用。如果两者都存在，则删除jquery_ujs。
当我遇到此问题时，删除工作正常，但我也遇到了双重删除确认。这个问题在同样的修复中得到了缓解。通过删除jquery_ujs引用，问题就消失了。
这个答案不是我自己的。实际上，我在阅读此条目后修复了此问题：link-to-confirm-displays-popup-twice
此answer中的评论有助于：
...删除在其中复制的jquery_ujs 来自application.js的rails_ujs停止弹出两次....
