连接模型附加属性的表单

Question

一个用户通过 UserSkills 拥有很多技能。一项技能通过 UserSkills 拥有多个用户。

在我的新用户表单中，我可以为技能添加复选框，但是如果我向 UserSkills 模型添加熟练（字符串）属性，我该如何包含它？

我当前的代码：

<%= f.label :skills %>
<%= hidden_field_tag "user[skill_ids][]", nil %>
<% Skill.all.each do |skill| %>
<%= check_box_tag "user[skill_ids][]", skill.id, @user.skill_ids.include?(skill.id), id: dom_id(skill) %>
<%= link_to skill.skilltitle, skill_path(skill.id) %>

Answer 1

class User < ActiveRecord::Base
  has_many :user_skills
  accepts_nested_attributes_for :user_skills
end

class UserSkill < ActiveRecord::Base
  belongs_to :user
  belongs_to :skill

  accepts_nested_attributes_for :skill
  accepts_nested_attributes_for :user
end

...同时..以您的形式

<%= form_for @user do |f| %>
  <%= f.fields_for :user_skills do |f2| %>
    <%# add your user_skill attributes here %>
    <%= f2.check_box :proficiency %>
    <%= f2.fields_for :user do |f3| %>
      <%#  user attributes to go here %>
    <% end %>
<% end %>
