我正在尝试保存插入表单的数据，当我按下保存并继续时，它再次进入“新”，我试图更改控制器中的错误操作并将其重定向到应用程序的任何页面但是它根本不响应错误操作，并且浏览器中的 url 更改为：

0.0.0.0:3000/students/15/student_previous_data/new?utf8=%E2%9C%93&student_previous_data[student_id]=15&student_previous_data[institution]=institution&student_previous_data[course]=course&student_previous_data[year]=2010&student_previous_data[total_mark]=60&commit=Save+%26+Proceed

对于年份属性，我使用的是 bootstrap-datepicker ，并且我使用了这个 JQuery 代码

jQuery ->
  $(".year").datepicker( { format: "yyyy", viewMode: "years", minViewMode: "years", autoclose: true });

这就是我的控制器中的创建操作

  def create
    @student_previous_data = StudentPreviousData.new(params[:student_previous_data])
    if @student_previous_data.save
      flash[:success] = 'Record Saved Successfully.'
      redirect_to '/user/dashboard'
    else
      flash.now[:error] = 'An error occurred please try again!'
      render 'new'
    end
  end

我如何使表格真正保存在数据库中？

将您的 form_for 更改为

<%= bootstrap_form_for(@student_previous_data, :url => student_student_previous_data_path(@student),
                       html: { class: 'form-horizontal' }, method: :post) do |f| %>

从

<%= bootstrap_form_for(@student_previous_data, :url => new_student_student_previous_datum_path(@student),
                       html: { class: 'form-horizontal' }, method: :get) do |f| %>

它会起作用。

这是名称本身的问题，控制器应该接受名称，singular但表单接受名称plural，我已经创建了一个新名称，controller并且控制器中model的名称'previous_detail'应该是>>redirect_to new_student_previous_detail_path(@student)并且表单应该是student_previous_details_path(@student)

你在使用GET方法，使用POST方法。

并student_student_previous_data_path(@student)在 url 中使用

您的表单网址不正确。您的网址应如下所示：

:url => student_student_previous_data_path(@student)

您当前的网址

:url => new_student_student_previous_datum_path(@student)

总是会将您直接重定向到您的新操作。你永远不会通过 create 动作。
