Show list of items not at the show page but at the index page

Question

May you help me please..

I have three models: Day, Course, Dish

class Day < ApplicationRecord 
  has_many :courses
   has_many :dishes, through: :courses 
end

class Course < ApplicationRecord 
  belongs_to :day 
  belongs_to :dish 
end

class Dish < ApplicationRecord
   has_many :courses 
  has_many :days, through: :courses
 end

class DaysController < ApplicationController
    before_action :require_user  

  def index 
    @days = Day.all 
  end
    
  def show 
    @day = Day.find(params[:id])
     @dishes = @day.dishes 
  end

  end

View index.html.erb:


    
    <% @days.each do |day| %> 
       
      <% end %> 
    <%= link_to "Back to Profile", profile_dir_path(@user), method: "get" %>

View show.html.erb:

Menu 
    <% @dishes.each do |dish| %>  
       
       <%= dish.name%>
        <%= dish.description%> 
          
     <% end %>

What do I really need: I need to display a list of dishes on the index page by clicking on the day button. (When user click on the weekday button he need to see menu list of items (in my implementation dishes))

But as you see I made display dishes on the show page.... May you give a couple of advise how can i realize it?

You can try with AJAX request. Here I have added one AJAX request with day button.

# app/views/days/index.html.erb


    
    <% @days.each do |day| %> 
      <%= button_to day.weekday, day_path(day), data: { remote: true } %> 
    <% end %> 
    
    
    <%= link_to "Back to Profile", profile_dir_path(@user), method: "get" %>

Here I am adding one view file for JS request.

# app/views/days/show.js.erb

$('.days').find('#menuList').html('<%= j (render "dishes", dishes: @dishes) %>');

Here I am adding _dishes.html.erb partial for rendering dishes.

# app/views/days/_dishes.html.erb

Menu 
<%= link_to "Close", "#", id: "closeLink" %>

<% dishes.each do |dish| %>  
    
    <%= dish.name %>
     <%= dish.description %> 
     
<% end %>

Enjoy :-)
