Menu
I'm looking for solution to have partial with multiple yields.
In real example I have this views structure:
Basic application.erb (/views/layouts/application.erb):
<!DOCTYPE html>
<head>
<title>Some title</title>
</head>
<body>
<div class="page">
<%= yield %>
</div>
</body>
</html>
Some partial to DRY my code (/views/shared/content.erb):
<div class="content">
<div class="sidebar">
<%= yield :sidebar %>
</div>
<div class="main">
<%= yield %>
</div>
</div>
And controller view (/views/home/index.erb):
<%= render :partial => 'layouts/header' %>
<%= render :partial => 'shared/navigation' %>
<% # It is close to what I want to do %>
<%= render :layout => 'shared/content' do %>
<% content_for :sidebar do %>
<%# This is will go to application.erb, not in content.erb %>
<%= render :partial => 'shared/menu' %>
<% end %>
<%= yield %>
<% end %>
<%= render :partial => 'layouts/footer' %>
So the main issue here is to have a template block with multiple yield areas and ability to pass custom html or render another partial.

A partial allows you to separate layout code out into a file which will be reused throughout the layout and/or multiple other layouts. For example, you might have a login form that you want to display on 10 different pages on your site.
Rails Guides describes partials this way: Partial templates - usually just called "partials" - are another device for breaking the rendering process into more manageable chunks. With a partial, you can move the code for rendering a particular piece of a response to its own file.
Without any arguments, yield will render the template of the current controller/action. So if you're on the cars/show page, it will render views/cars/show. html. erb . When you pass yield an argument, it lets you define content in your templates that you want to be rendered outside of that template.
By default, if you use the :plain option, the text is rendered without using the current layout. If you want Rails to put the text into the current layout, you need to add the layout: true option and use the . text. erb extension for the layout file.
This question is old, however, it's still relevant when I was searching for an answer on Google.
I've come up with a solution, while still not beautiful, works very well. The idea uses Rails' capture method, which takes a block and stores its contents into a variable:
controller.html.erb
<%= render 'shared/partial', body: capture { %>
My body content
<% }, footer: capture { %>
My footer content
<% } %>
shared/_partial.html.erb
<div id="body"><%= body %></div>
<div id="footer"><%= footer %></div>
Hope this helps someone!

In my case I've found solution like this.
On my controller view (/views/home/index.erb):
<% sidebar_content = render :partial => 'shared/slider' %>
<%= render :layout => 'shared/content', :locals => {:sidebar => sidebar_content} do %>
<%= yield %>
<% end %>
The partial with multiple areas (/views/shared/content.erb):
<div class="content">
<div class="sidebar">
<%= sidebar %>
</div>
<div class="main">
<%= yield %>
</div>
</div>
This solution doesn't look pretty, but it works. I hope to find something better in near future.
