Question

我有一个名为org和department的模型。每当组织注册时，它必须通过以逗号分隔值的形式输入部门名称来创建其所拥有的部门列表。部门列表也可以稍后编辑。这些是我的模特：

0rg

class Org < ActiveRecord::Base
  has_many :departments, dependent: :destroy
  attr_accessible :name, :website, :department_list
  validates :name, presence: true
  validates :website, presence: true

  def department_list
    departments.collect { |d| d.department_name }.join(', ')
  end

  def department_list=(text)
    if id && text
      departments.destroy_all
      text.split(',').each do |d|
        departments.create(department_name: d.strip.capitalize)
      end
   end
 end
end

系

class Department < ActiveRecord::Base
  attr_accessible :department_name, :org_id
  belongs_to :org
end

我的观点

<%= f.text_area :department_list, :cols => "10", :rows => "10" %>

问题：

当组织通过输入部门名称作为逗号分隔值进行注册时，它不会存储在数据库中。但是，当组织稍后通过编辑操作更新字段时，只会存储部门名称，并且可以随时进一步编辑。我希望在组织注册时存储部门名称。

请帮助。

class Webs::RegistrationsController < Devise::RegistrationsController
  prepend_before_filter :require_no_authentication, :only => [ :new, :create, :cancel ]
  prepend_before_filter :authenticate_scope!, :only => [:edit, :update, :destroy]

  # GET /resource/sign_up

  def new
    build_resource({})
    respond_with self.resource
  end

  # POST /resource
  def create
    build_resource(sign_up_params)

    # customized code begin

    # create a new child instance depending on the given user type



    child_class = params[:web][:user_type].camelize.constantize
    resource.role = child_class.new(params[child_class.to_s.underscore.to_sym])

    # first check if child instance is valid
    # cause if so and the parent instance is valid as well
    # it's all being saved at once
    valid = resource.valid?
    valid = resource.role.valid? && valid

    # customized code end

    if valid && resource.save
      if resource.active_for_authentication?
        set_flash_message :notice, :signed_up if is_navigational_format?
        sign_up(resource_name, resource)

      end
    else
     clean_up_passwords resource
     render :new
    end
 end

 # GET /resource/edit
 def edit
   render :edit
 end

 # PUT /resource
 # We need to use a copy of the resource because we don't want to change
 # the current user in place.
 def update

   self.resource = resource_class.to_adapter.get!(send(:"current_#{resource_name}").to_key)
   prev_unconfirmed_email = resource.unconfirmed_email if resource.respond_to?(:unconfirmed_email)

   if resource.update_with_password(account_update_params)
      resource.role.update_attributes(params[:org])
      resource.role.update_attributes(params[:user])
      if is_navigational_format?
        flash_key = update_needs_confirmation?(resource, prev_unconfirmed_email) ?
          :update_needs_confirmation : :updated
        set_flash_message :notice, flash_key
      end
      sign_in resource_name, resource, :bypass => true
      respond_with resource, :location => after_update_path_for(resource)
   else
      clean_up_passwords resource
     render :edit
   end
 end
end

未存储逗号分隔值
