Community has_many CommunityTopics
example.com/shop/WALMART/topic/new にアクセスし
、サブミット後に新しいレコードを作成すると、CommunityTopics のフォームが表示されます。
しかし、入力したすべてのデータは保存されず、すべて空になります:(

私のコードは

ルート.rb

resources :communities, :path => "shop", do
    resources :community_topics, :path => "topic", :as => :'topic'
end

models/community.rb

def to_param
  "#{community_name}"
end

community_topics_controller.rb #new

  def new
    @community = Community.find_by_community_name(params[:community_id]) 
    @community_topic = @community.community_topics.build 
    @community_topic.user_id = current_user.id 


    respond_to do |format|
      format.html # new.html.erb
      format.json { render json: @community_topic }
    end
  end

community_topics_controller.rb #create

  def create
    @community = Community.find_by_community_name(params[:community_id]) 
    @community_topic = @community.community_topics.build (params[:id]) 

    respond_to do |format|
      if @community_topic.save
        format.html { redirect_to community_topic_path(@community.community_name, @community_topic), notice: 'Community topic was successfully created.' }
        format.json { render json: [@community, @community_topic], status: :created, location: @community_topic }
      else
        format.html { render action: "new" }
        format.json { render json: @community_topic.errors, status: :unprocessable_entity }
      end
    end
  end

この行を見てください

@community_topic = @community.community_topics.build (params[:id])

それに間違ったパラメーターを渡しました。する必要があります

params[:community_topic] :)
