「48 | メッセージと会話 | 会話表示」の内容をBootstrapに変更します。
会話表示できるようにします。
「app\controllers」フォルダに「conversations_controller.rb」ファイルを新規作成して下さい。
app\controllers\conversations_controller.rb(新規作成したファイル)
class ConversationsController < ApplicationController before_action :get_conversations def list end def show @user = User.find(params[:id]) @conversation = Conversation.where("(sender_id = ? AND receiver_id = ?) OR (sender_id = ? AND receiver_id = ?)", current_user.id, params[:id], params[:id], current_user.id ).first if !@conversation.present? redirect_to conversations_path, alert: "無効です" else @messages = Message.where(conversation_id: @conversation.id) end end private def get_conversations @conversations = Conversation .where("sender_id = ? OR receiver_id = ?", current_user.id, current_user.id) .order(updated_at: :desc) end end
ルートの設定をします。
「config\routes.rb」ファイルに以下の記述を追加します。
記述追加 config\routes.rb(18,19行目)
get '/conversations', to: 'conversations#list', as: "conversations" get '/conversations/:id', to: 'conversations#show', as: "conversation_detail"
