how to render partial on everything except a certain action

I have a _header.html.erb partial which is where I put my navbar

on my launch page I don't want to display the navbar.

this is the body of application.html.erb

<body>
<%= render 'layouts/header' %>
<div id="container">
    <%= yield %>
</div>

</body>

How do I render it on every action except specific actions on specific controllers?

Solution

  • Replace your render with this:

    <%= render 'layouts/header' unless @disable_nav %>

    Then you can simply set disable_nav to true in any controller action you like:

    def landing_page
  @disable_nav = true
end

    As a before_action, which I'd encourage over the above:

    application_controller.rb

    def disable_nav
  @disable_nav = true
end

    my_controller

    before_action :disable_nav, only: [:landing_page]
