I think I have the same issue with this. Using multiple yields to insert content
And I tried the solution. I tried to have <%= yield :content %> in my application.html.erb and have content_for :content and the yield inside, in my view. But it is not working on my app. Can you please explain more or give sample scenario on my problem?
The links inside, must not reload, so I will not use render partial on every template I will display.
I just recently started learning Rails so it was all a little bit confusing for me. Thank you.
I tried this; this is just an example I will fix the connection of sidebar later.
in my applicaion.html.erb
<!DOCTYPE html>
<html>
<head>
<title>Clinks</title>
<%= stylesheet_link_tag "application", media: "all" %>
<%= javascript_include_tag "application" %>
<%= csrf_meta_tags %>
</head>
<body>
<section id="container" >
<%= render 'layouts/header' %>
<%= render 'layouts/sidebar' %>
<section id="main-content">
<section class="wrapper">
<div class="row">
<!-- %= yield % -->
<%=yield(:content) %>
</div><!--/row -->
</section><!--/wrapper -->
</section><!--/main-content -->
</section><!--/container -->
</body>
</html>
in my menu_tables.html.erb inside layouts folder.
<% content_for(:content) do %>
<%= render 'menu_tables/sidemenu' %>
<%= yield %>
<% end %>
<%= render template: "layouts/application" %>
in my routes.rb
Rails.application.routes.draw do
root :to => 'pages#home'
resources :menu_tables, except: [:show]
end
then in _sidemenu.html.erb under menu_tables controller is the code for the links, so each links from sidebar have different sidemenu.
May be you need to tell your controller to use
layout 'menu'. In the link you provided names of the controller and layout matched, so it worked 'magically'. See guides:(Note: you can check what layout is used in logs, look for line similar to
Rendered menu_items/index.html.erb within layouts/application)
