Ruby on Rails的爲HAS_ONE關係

Question

編輯表單我有一個clan.rb和clan_options.rb

clan.rb

class Clan < ActiveRecord::Base 
    has_one :options, :class_name => "ClanOptions", :foreign_key => "clan_id", dependent: :destroy 
    accepts_nested_attributes_for :options 
end 

clan_options.rb

class ClanOptions < ActiveRecord::Base 
    belongs_to :clan 
end 

要創建一個

<%= form_for @clan, :html => {:class => 'form-horizontal'} do |clan| %> 
    <fieldset> 
     <!-- Form stuff --> 
     <%= clan.fields_for :options do |o| %> 
      <!-- o.text_field --> 
     <% end %> 
    </fieldset> 
<% end %> 

我可以更新clan.rb的領域，但是當我嘗試：爲clan.rb和clan_options.rb我用下面的edit.html.erb編輯表單編輯值backgroundurl它不會保存它。 Backgroundurl是clan_options.rb

編輯之一：更新代碼和文本。

clans_controller.rb

class ClansController < ApplicationController 
    before_filter :check_login, :only => [:new, :edit] 
    before_filter :check_bound, :only => [:new, :edit] 
    before_filter :check_clan, :only => :new 

    def update 
     @clan = Clan.find(params[:id]) 
     if @clan.update_attributes(clan_update_params) 
      flash[:status] = TRUE 
      flash[:alert] = "Successfully updated your clan." 
      redirect_to clan_path(params[:id]) 
     else 
      flash[:status] = FALSE 
      flash[:alert] = @clan.errors.full_messages 

      redirect_to edit_clan_path(@clan.id) 
     end 
    end 

    def edit 
     clan = Clan.where(id: params[:id]) 
     if !clan.blank? 
      @clan = Clan.find(params[:id]) 

      user = User.where(id: session[:user_id]) 
      if !user.blank? 
       #De gebruiker is ingelogt en zit in de clan 
       @user = User.find(session[:user_id]) 
       if @clan.id != @user.clan.id 
        flash[:status] = FALSE 
        flash[:alert] = 'That was not your clan, you may not edit theirs.' 
        redirect_to clans_path 
       elsif @user.clanmember.group.rank != 10 
        flash[:status] = FALSE 
        flash[:alert] = "You must be the leader to edit the clan." 
        redirect_to clan_path(@clan.id) 
       end 
      end 
     else 
      flash[:status] = FALSE 
      flash[:alert] = 'that clan doesn\'t exist or has been removed.' 
      redirect_to clans_path 
     end 
    end 

    def clan_params 
     params.require(:clan).permit(:name, :prefix, :description, :user_id) 
    end 

    def clan_update_params 
     params.require(:clan).permit(:name, :prefix, :description, :user_id, options: [:id, :clan_id, :backgroundurl]) 
    end 
end
