Question

我有两个模型Employee和Overtime Definition关联设置如下

员工

class Employee < ActiveRecord::Base

has_many :overtime_definitions

加班定义

class OvertimeDefinition < ActiveRecord::Base

belongs_to :employee

我为员工创建了一个加班定义，一切看起来都很好。但是我在为员工编辑时却遇到了麻烦。

overtime_definitions__controller：

    def new
        @flag = params[:flag]
        @employee = Employee.find(params[:id])
        @overtime = OvertimeDefinition.new
     end

      def create
        @employee = Employee.find(params[:overtime_definition][:employee_id])
        @overtime = OvertimeDefinition.new(params[:overtime_definition])
        if (params[:half_day_extra_duty_hours][:hour].to_s !="" || params[:half_day_extra_duty_hours][:minute].to_s !="")
          @overtime.half_day_extra_duty_hours   = params[:half_day_extra_duty_hours][:hour].to_s + ":" + params[:half_day_extra_duty_hours][:minute].to_s + ":" + "00"
        else
         @overtime.half_day_extra_duty_hours = nil
        end
        if (params[:full_day_extra_duty_hours][:hour].to_s !="" || params[:full_day_extra_duty_hours][:minute].to_s !="")
          @overtime.full_day_extra_duty_hours   = params[:full_day_extra_duty_hours][:hour].to_s + ":" + params[:full_day_extra_duty_hours][:minute].to_s + ":" + "00"
        else
         @overtime.full_day_extra_duty_hours = nil
        end
     if @overtime.save
      flash[:notice] = "Overtime Successfully Created for #{@employee.name}"
      redirect_to :action => 'search_overtime'
    end
  end

def edit
    @flag = params[:flag]
    @overtime = OvertimeDefinition.find(params[:id][:employee_id])
    @employee = Employee.find(params[:id])
  end

  def update
    @employee = Employee.find(params[:id])
    @overtime = OvertimeDefinition.find(params[:id])
    if @overtime.update_attributes(params[:overtime_definition])
     flash[:notice] = "Overtime Successfully Updated for #{@employee.name}"
            redirect_to :action => 'search_overtime'
    else
     render :action => 'edit',:flag=>params[:flag]
    end
  end

在编辑方法

中尝试使用这些

@overtime = OvertimeDefinition.find(params[:id][:employee_id])

#gives me can't convert Symbol into Integer错误。
@overtime = OvertimeDefinition.find(params[:id])

#gives me Couldn't find OvertimeDefinition with ID=1353 error.Actually 1353是该员工的ID。

3。@overtime = OvertimeDefinition.find(params[:employee_id])

#gives me couldn't find OvertimeDefinition without an ID错误。

我的_search_overtime_employee_list包含用于新操作和编辑操作的这些链接

<%=link_to "Calculation" ,:action => "new",:id=>employee.id, :flag=>"Calculation" %>

<%= link_to "Re-Calculate",:action => "edit",:id=>employee.id,:flag=>"Re-Calculate" %>

new.rhtml

<%= form_tag :action => 'create' do %>
<%= render :partial =>'form'%>
<center>
    <%= submit_tag "Save",:onclick=>"return validate()",:class=>"buttons"%>
</center>
<% end %>
<%= link_to "Back" ,:action => "search_overtime" %>

edit.rhtml

<%= form_tag :action => 'update', :id=>@employee.id,:flag=> params[:flag],:value=>params[:id] %>
<%= render :partial =>'form'%>
<center>
    <%= submit_tag "Update",:onclick=>"return validate()",:class=>"buttons"%>
</center>
<%= link_to "Back" ,:action => "search_overtime" %>

与_form.rhtml

员工详细信息

<table cellspacing="5">
 <tr>
    <td><b>Employee Code</b></td>
    <%= hidden_field 'overtime_definition','employee_id',:value=>params[:id] %>
    <td><%= @employee.employeeid %></td>

    <td><b>Location</b></td>
    <td><%= @employee.location.name%></td>

</table>

</br>

    </tr>
     <tr>

    <td colspan="2" id="ov_hm" style="display: none">

     <%= od.text_field :full_day_amount, :onkeypress => "return numbersonly(event)", :style => "width:40px" %>
     </td>
 </tr>
<%end%>

我完全失去了这个编辑动作的工作。非常感谢任何帮助！

Answer 1

您当前的edit链接是：

<%= link_to "Re-Calculate",:action => "edit",:id=>employee.id,:flag=>"Re-Calculate" %>

在您的编辑操作中：

@overtime = OvertimeDefinition.find（params [：id] [：employee_id]）##让我无法将符号转换为整数错误。

根据修改链接，您可以直接在查询参数中传递:id，您可以将其作为params[:id]进行访问。你的params哈希中没有params[:id][:employee_id]所以当你说params[:id][:employee_id] Ruby试图将:employee_id转换为一个符号整数时。因此，错误。

我认为你应该从你的链接传递:id中的OvertimeDefinition记录的id。并以

的形式访问它

@overtime = OvertimeDefinition.find(params[:id])

在Controller的行动中。

@overtime = OvertimeDefinition.find（params [：id]）##给了我不能找到ID = 1353错误的OvertimeDefinition。实际上1353是id 那个员工。

这是因为您在employee id中传递params[:id]，所以显然这不起作用。你需要在这里传递OvertimeDefinition id。

@overtime = OvertimeDefinition.find（params [：employee_id]）##给了我没有ID错误，找不到OvertimeDefinition。

您未在:employee_id链接中的查询参数中传递任何edit。因此，params [：employee_id]将为nil并且find方法失败，因为您没有向其传递任何ID。

解决方案：

更新您的edit link，如下所示：

<%= link_to "Re-Calculate",:action => "edit",:id=> @overtimedefinition.id , :employee_id => employee.id,:flag=>"Re-Calculate" %>

将@overtimedefinition.id替换为适当的OvertimeDefinition记录ID。由于您还没有共享代码，我不知道OvertimeDefinition变量的名称。

将您的edit操作更新为：

  def edit
    @flag = params[:flag]
    @overtime = OvertimeDefinition.find(params[:id])
    @employee = Employee.find(params[:employee_id])
  end

无法获得编辑功能工作
