[FIXED] How can I yield a "future" content_for tag in Rails 3?

May 18, 2022 content-for, partial, ruby-on-rails-3, templates, yield No comments

Issue

I have a template with 2 partials. In the first one, I am yieleding content which is only defined in the second partial (with a content_for tag). The problem is that the yield does not recognize that content yet since it was not defined.

If I reverse the order of the partials the yield recognized the content, yet the layout is not as I desire obviously...

Is there a way to do this? Thank you.

Solution

Okay, this was actually an easy fix. I moved the second partial into a content_for block placed above the first partial, and then just yielded it instead of declaring it as a partial.

[FIXED] how to render partial on everything except a certain action

May 18, 2022 content-for, partial, render, ruby-on-rails-3 No comments

Issue

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_filter, which I'd encourage over the above:

application_controller.rb

def disable_nav
  @disable_nav = true
end

my_controller

before_filter :disable_nav, only: [:landing_page]
