Question

我已将种子数据添加到class_details表并进行了迁移。在我的user_classes表中，我需要获取用户选择的class_detail的对应ID。但是我无法将class_detail ID保存在user_class表中。 user_class表取决于用户表。谁能帮助我！预先感谢。

seed.rb

ClassDetail.create!([
  {standard_name: "Class 1 to 5" , class_category: "PRIMARY"},
  {standard_name: "Class 6 to 8" , class_category: "MIDDLE"},
  {standard_name: "Class 9 to 10" , class_category: "SECONDARY"},
  {standard_name: "Class 11 to 12" , class_category: "HIGHER SECONDARY"}
  ])

user_class.rb

class UserClass < ApplicationRecord
  belongs_to :user
  belongs_to :class_detail
  accepts_nested_attributes_for :class_detail, update_only: true

  validates_presence_of :user_id
end

class_detail.rb

class ClassDetail < ApplicationRecord
  has_many :user_class
  has_many :users, through: :user_class
end

user.rb

has_one :user_class, dependent: :destroy
has_many :class_details, through: :user_classes

控制器

def update_profile
    if @user.update(user_params)
      redirect_to profile_index_path, notice: 'Profile was successfully updated.'
    else
      render :index
    end
  end
private

  def set_user
    @user = User.find(current_user.id)
    @user.user_class || @user.build_user_class
  end

  def user_params
    params.require(:user).permit(:name,user_class_attributes: %i[id standard_name class_category class_detail_id])
  end
end

查看代码

 <%= form_for(@user, url: {action: 'update_profile'}, html: {class: 'form-horizontal'}) do |f| %>
<%= f.fields_for :user_class, @user.user_class do |c| %>
<div class="card card-primary">
  <div class="card-header">
    <h3 class="card-title">
      <%= t('.education') %>
    </h3>
  </div>
  <div class="card-body">
    <div class="form-group">
      <label for="example-text-input">
        Class Name
      </label>
      <div class="col-sm-10">
        <%= c.select :class_detail_id, ClassDetail.all.collect { |p| [ p.standard_name, p.id ] }, {}, {class: 'form-control'} %>
      </div>
    </div>
  </div>
</div>
<% end %>
<div class="card-footer">
  <%= f.submit 'Save Changes', class: 'btn btn-primary' %>
  &nbsp;&nbsp;
  <%= link_to 'Back', root_path, class: 'btn btn-secondary' %>
</div>
<% end %>
