Question

我有一个bootstrap模式，当我点击按钮时，将调用此引导模型（打开弹出菜单）并传递不同的 offer_id 。

此弹出菜单打开一个表单（如编辑表单），我编辑了所有信息，然后点击编辑按钮，然后只更新了第一条记录。

例如，我想编辑 offer_id = 1 的信息，填写所有表单并提交，然后 offer_id = 1 更新 not offer_id = 5

所以我不确切地知道我错在哪里，我错过了什么..

在同一页面上修改按钮和模型（ _employee_details.html.erb ）

修改按钮

<div class="edit-recr-wrp1"> 
       <button type="button" class="btn btn-primary fa fa-pencil-square-o" data-toggle="modal" data-target="#exampleModal1" data-offer_id="<%= emp['offer_letter_id'] %>" data-employee_id="<%= emp['employee_id'] %>"></button>               
</div>

模态“#exampleModal1”

    <div class="modal fade" id="exampleModal1" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">

Answer 1

关于编辑和更新方法，你有一些想念。你应该通过id找到，我的意思是它应该像

@employees = EmployeeDetail.find(id)

其次请在更新方法中写一个加注，以检查传递数据的真实表单或仅传递第一个数据，这就是为什么它只更新了您的第一列。在def update =＆gt;

raise params.inspect

然后你会确定自己的参数是否正确，def employee_params方法是否有效？

Answer 2

你应该使用

def update
    @employees = EmployeeDetail.find(params[:employee_details][:offer_letter_id])

如果offer_letter_id是您的主键或

def update
    @employees = EmployeeDetail.find_by(offer_letter_id: params[:employee_details][:offer_letter_id])

在任何其他情况下......

如何将参数从form_for方法传递到rails中的控制器方法？
