【学習6.0】【MacOSX】会話

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(16,17行目)

  get '/conversations', to: 'conversations#list', as: "conversations"
  get '/conversations/:id', to: 'conversations#show', as: "conversation_detail"

config\routes.rb

Rails.application.routes.draw do

  # ルートを　app\views\pages\home.html.erb　に設定
  root 'pages#home'

  devise_for :users, 
              path: '', 
              path_names: {sign_up: 'register', sign_in: 'login', edit: 'profile', sign_out: 'logout'},
