Rails, render a different header just on homepage

Question

I'm creating a rails app and I must differentiate the header for home page.

I already created a partial with the _home_header version and the _header version to use in every page, but I don't know how can I manage the change.

The header is included in my layout, and I render the same layout for every page. How can I tell to "layout" to use the _home_header version instead of the standard version when I request homepage?

Answer 1

I would use the current_page? helper and look at the root_path.

# app/views/layouts/application.html.erb
<% if current_page?(root_path) %>
    <%= render 'layouts/home_header' %>
<% else %>
    <%= render 'layouts/header' %>
<% end %>

Answer 2

Use something like this in application.html.erb

<% if request.original_url == root_url %>  ## Specify the home url instead of root_url(if they are different)
  <%= render 'layouts/home_header' %>      ## Assuming that _home_header.html.erb is under layouts directory
<% else %>
  <%= render 'layouts/header' %>           ## Assuming that _header.html.erb is under layouts directory
<% end %>
