Question

我正在尝试通过employee的显示页面上的employee_skill表格向员工添加技能，但每次尝试创建时都会收到以下错误。

错误：

ActiveRecord::RecordNotFound in EmployeeSkillsController#create

Couldn't find Employee with 'id'=

<div class="section">
<div class="top-border left"></div>
  <div class="top-border right"></div>
    <h3> Add Skill</h3>
    <%= form_for([EmployeeSkill.new]) do |f| %>
    <%= @employee.name%>
<div class="field">
     <%= f.label :Skill %><br>
    <%= f.collection_select :skill_id, Skill.all, :id, :skillType, :prompt => "Select skill" %>

  <div class="actions">

    @employee_skill = EmployeeSkill.new

在EmployeeSkill操作

中初始化show的实例

@employee = Employee.find(params[:id]) 
@employee_skill = @employee.employee_skills.new
# The above statement will set :employee_id with employee's id

然后以表格

使用它

<%= form_for([@employee, @employee_skill]) do |f| %>

如果:url生成不正确，您也可以明确传递

<%= form_for([@employee, @employee_skill], url: employee_employee_skills_path(@employee)) do |f| %>

在尝试添加到表
