我正在尝试保存插入到表单中的数据，当我按下save＆amp;继续它再次转到'新'并且我试图改变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year属性，我使用的是bootstrap-datepicker，我使用这个JQuery Code
jQuery ->
$(".year").datepicker( { format: "yyyy", viewMode: "years", minViewMode: "years", autoclose: true });
这就是我控制器中的创建动作
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

如何让表单转到true以保存在数据库中？
答案 0 :(得分：1)
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)
始终会将您直接重定向到您的新操作。您永远不会传递创建操作。
答案 1 :(得分：1)
您正在使用GET方法，请使用POST方法。
在网址中使用student_student_previous_data_path(@student)
答案 2 :(得分：1)
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| %>
来自
<%= 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。
答案 3 :(得分：1)
这是名称本身的一个问题，控制器应该接受名称为singular，但表单接受名称为plural，我创建了一个新的controller和{{ 1}}在控制器中名称为model，它应该是＆gt;＆gt; 'previous_detail'并且表单应为redirect_to new_student_previous_detail_path(@student)
