Javascript 控制器操作正在以html格式处理，而不是执行.js.erb文件

我正在尝试将datepicker添加到我的应用程序中，以将日期值传递给我的控制器，并根据日期范围获取筛选的记录…但我不断收到错误

以下是我的费用控制者行动：

def dateFilter 
   @expenses = current_user.expenses.where(:created_at =>   params[:start_date]..params[:end_date])

  respond_to do |format|
    format.html
    format.json { render json: @expenses }
    format.js
   end
end

我的应用程序/views/expenses/dateFilter.js.erb

$('.dateFilter').append('<%= escape_javascript(render(@expenses)) %>');

304ms内完成500个内部服务器错误

ActionView::Template::Error (undefined method `datepicker_input' for #<#<Class:0x000000037b87e0>:0x00000003500570>):

2:     <%= datepicker_input "expense", :start_date, :class => 'dateFilter', :dateFormat => 'mm/dd/y' %>
3:     <%= datepicker_input "expense", :end_date, :class => 'dateFilter', :dateFormat => 'mm/dd/y' %>
4:     <%= submit_tag "Submit" %>
5:     <% end %>

有人请帮我解决我的问题…

范围查询只对DateTime对象起作用，而您在其中传递字符串。尝试将参数转换为datetime对象，它应该可以工作

@expenses=current_user.expenses.where:created_at=>params[：start_date]。to_datetime..params[：end_date]。to_datetime

您的表单标签有一个：class=>“date_form”和：remote=>true，应该作为javascript请求正确提交。但是application.js中的代码

$“日期表格”。提交

这意味着date_表单不是一个类，而是一个id

是否有另一张id为date_form的表格

我建议把console.logis放在这甚至可以执行的地方；在您的application.js之前

$.ajax({
  type: 'POST',

谢谢你的回答，但是我的dateFilter.js.erb没有被执行。控制器操作作为html而不是js执行。它给出了缺少模板的错误。根据您在问题中显示的错误，@expenses对象为nil，这就是渲染对象抛出错误的原因。但是你现在所说的和问题中的不一样？您是否有用于呈现html的datefilter.html.erb？请发布整个错误堆栈，以便我能更好地帮助您。是的，添加到_datetime给了我命名错误，但它帮助我找到了一个拼写错误，修复后我现在得到了丢失的模板错误。我有_dateFilter.html.erb部分，我在上面的日志中显示了它。我还编辑了日志以显示缺少模板的错误。嘿，dateFilter是一个部分。请将文件重命名为dateFilter.html.erb，它应该可以工作。请记住，Rails的理念是约定优于配置。你需要特别遵循这一点。正如你所建议的，我添加了console.log，即使我从我的表单标签中删除了：class=>“date\u form”和$“date\u form”。submit。。从我的application.js。将我的_dateFilter.html.erb重命名为dateFilter.html.erb后，我编辑了日志。
