x-editable ActionController::ParameterMissing（参数缺失或值为空：employee）

Question

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：

视图如下：

          <table class="table table-striped table-bordered table-hover" id="sample_1">
                <thead>
                  <tr>
                    <th>Company name</th>
                    <th>Family</th>
                    <th>First name</th>
                    <th>Last name</th>
                    <th>Dob</th>
                    <th>Sub status</th>
                    <th>Gender</th>
                    <th>Uses tobacco</th>
                    <th>Tobacco cessation</th>
                    <th>Emp status</th>
                    <th>Coverage type</th>
                    <th>Currently enrolled</th>
                    <th>Current anthem</th>
                    <th>Current plan</th>
                    <th>Quote</th>
                    <th>Premium</th>
                  </tr>
                </thead>

                <tbody>
                  <% @employees.each do |employee| %>
                    <tr>
                     <td> 
                          <a href="#" data-xeditable="true" data-pk="<%= employee.id %>" data-model="PUT" data-type="text" data-name = "company_name" data-url="/employees/<%= employee.id %>" data-title="Enter title">

                             <%= employee.company_name %>
                          </a>
                     </td>

                      <td><%= employee.family_id %></td>
                      <td><%= employee.first_name %></td>
                      <td><%= employee.last_name %></td>
                      <td><%= employee.dob %></td>
                      <td><%= employee.sub_status %></td>
                      <td><%= employee.gender %></td>
                      <td><%= employee.uses_tobacco %></td>
                      <td><%= employee.tobacco_cessation %></td>
                      <td><%= employee.emp_status %></td>
                      <td><%= employee.coverage_type %></td>
                      <td><%= employee.currently_enrolled %></td>
                      <td><%= employee.current_anthem %></td>
                      <td><%= employee.current_plan_id %></td>
                      <td><%= employee.quote_id %></td>
                      <td><%= employee.premium %></td>

                    </tr>
                  <% end %>
                </tbody>
              </table>

这是视图的控制器：

class EmployeesController < ApplicationController
  before_action :set_employee, only: [:show, :edit, :update, :destroy]
  skip_before_filter :verify_authenticity_token
  def import
    Employee.import(params[:file])
    redirect_to employees_url, notice: "Census imported."
  end


  # GET /employees
  # GET /employees.json
  def index
    @employees = Employee.all
  end

  # GET /employees/1
  # GET /employees/1.json
  def show
  end

  # GET /employees/new
  def new
    @employee = Employee.new
  end

  # GET /employees/1/edit
  def edit
  end

  # POST /employees
  # POST /employees.json
  def create
    @employee = Employee.new(employee_params)

    respond_to do |format|
      if @employee.save
        format.html { redirect_to @employee, notice: 'Employee was successfully created.' }
        format.json { render :show, status: :created, location: @employee }
      else
        format.html { render :new }
        format.json { render json: @employee.errors, status: :unprocessable_entity }
      end
    end
  end

  # PATCH/PUT /employees/1
  # PATCH/PUT /employees/1.json
  def update
    respond_to do |format|
      if @employee.update(employee_params)
        format.html { redirect_to @employee, notice: 'Employee was successfully updated.' }
        format.json { render :show, status: :ok, location: @employee }
      else
        format.html { render :edit }
        format.json { render json: @employee.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /employees/1
  # DELETE /employees/1.json
  def destroy
    @employee.destroy
    respond_to do |format|
      format.html { redirect_to employees_url, notice: 'Employee was successfully destroyed.' }
      format.json { head :no_content }
    end
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_employee

    end

    # Never trust parameters from the scary internet, only allow the white list through.
    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


end

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。

员工路线：

import_employees POST   /employees/import(.:format)         employees#import
       employees GET    /employees(.:format)                employees#index
                 POST   /employees(.:format)                employees#create
    new_employee GET    /employees/new(.:format)            employees#new
   edit_employee GET    /employees/:id/edit(.:format)       employees#edit
        employee GET    /employees/:id(.:format)            employees#show
                 PATCH  /employees/:id(.:format)            employees#update
                 PUT    /employees/:id(.:format)            employees#update
                 DELETE /employees/:id(.:format)            employees#destroy

如果我可以提供任何其他帮助找到解决方案，请告诉我。

Answer 1

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"。
