我试图提交一个“空白”表单,故意触发错误.
但是,它仍然响应“成功”功能而不是标记错误.但是,没有添加任何记录.
当我在输入字段中提交信息时,表单可以正常工作.
形成：
<%= simple_form_for :course,:url => {:action => 'create'},:remote => true do |f| %>
<%= f.input :title %>
<%= f.submit "Submit" %>
<% end %>
模型：
class Course < ActiveRecord::Base validates :title,presence: true end
控制器：
def create
@course = Course.new(course_params)
respond_to do |format|
if @course.save
format.html { redirect_to(:controller => 'schedule',:action => 'index') }
format.js
else
format.html { render :action => "new" }
format.js
end
end
end
create.js.erb
$(document).ready(function() {
$("form").on("ajax:success",function(e,data,status,xhr) {
alert("Success!");
}).bind("ajax:error",xhr,error) {
alert("Error!");
});
});
共享/ error_messages.html.erb
<% if object && object.errors.size > 0 %>
<div id="errorExplanation">
<h2><%= pluralize(object.errors.size,"error") %> prohibited this record from being saved.</h2>
<p>There were problems with the following fields:</p>
<ul>
<% object.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
我在这里做错了什么想法？谢谢！
解决方法
你不需要在你的js.erb文件中有document.ready.你可以这样做
调节器
if @result = @course.save ..
create.js.erb
<% if @result %>
alert("Success!");
<% else %>
$('#error-div').html('<%= j(render :partial => 'shared/error_messages',:object => @course) %>');
<% end %>
