x-editable ActionController::ParameterMissing（参数缺失或值为空：employee）
x-editable ActionController::ParameterMissing (param is missing or the value is empty: employee)
我正在尝试获取 x-editable gem，在此处找到：Bootstrap-x-editable-rails GitHub。我一直在寻找 1-2 天，但未能解决问题，所以我将其发布在这里。
我尝试将 x-editable 功能集成到我的数据中table，我已经做到了可以单击 table 元素和将弹出编辑框。但是，当我按 enter 键确认更改时，我在控制台中收到此错误：

我知道 skip_before_filter :verify_authenticity_token 代码片段使应用程序容易受到攻击，并且不会长期保留它，它只是我解决之前遇到的另一个问题的创可贴。

如果我可以提供任何其他帮助找到解决方案，请告诉我。
在您的控制器中，您的强参数定义如下所示：
def employee_params
params.require(:employee).permit(:company_name, :family_id, :first_name, :last_name, :dob, :sub_status, :gender, :uses_tobacco, :tobacco_cessation, :emp_status, :coverage_type, :currently_enrolled, :current_anthem, :current_plan_id, :quote_id, :premium)
end
这意味着它希望提交的数据包含一个名为 employee 的键，其值是包含任何这些允许的属性作为键的哈希值。
如果您查看正在提交的实际数据（在日志中），您会发现未遵循此格式：
{"PUT"=>{"company_name"=>"New Compa"}, "id"=>"3"}
我猜这是因为您在视图中的 <a> 元素上有 data-model="PUT"。请尝试将其更改为 data-model="employee"。
