formValidation jquery插件在rails上提交一个空白的设计注册表单

我正在为我的Devise注册表单使用formValidation查询插件。 该插件来自formValidation.io 。 我可以让表单注册有效或无效的条目，但它总是提交一个空白表格。 由于某种原因，表单显示它已填写，但我不断收到错误，说必填字段不能为空。 当我查看跟踪时，注册信息正在那里注册……但它在线路的某处丢失了。

跟踪：

您的问题是您在所有表单输入中设置了name属性。 不要那样做。

因为你用firstname ， lastname等填充它们，你的params看起来像 

 {"firstname"=>"fred", "lastname"=>"flintstone", "email"=>"wilma@bedrock.com", "pw1"=>"dino123", "pw2"=>"dino123", "commit"=>"Create Account"}

什么时候应该看起来像 

 {"user" => {"firstname"=>"fred", "lastname"=>"flintstone", "email"=>"wilma@bedrock.com", "pw1"=>"dino123", "pw2"=>"dino123" }, "commit"=>"Create Account"}

Rails将自动填充那些user[firstname] ， user[lastname]等，这将使你的参数看起来像： user: { firstname: 'blabla', lastname: 'something'}

如果需要手动设置name ，并且代码需要具有属性的user对象，则需要将其写为name="user[attribute_name]"
