A tip / duh moment:
I had to add some custom meta tags in a site I’m building. They were different for every page. I considered putting them in a model somewhere, but that seemed like overkill since they weren’t being updated on any kind of regular basis. I also considered making different views that used other partials to fill out the content but that seemed messy.
I ended up creating an instance variable in my controller called @metas. It’s a hash that looks like this:
@metas = {
description: "This is the meta description for the page",
keywords: "foo, bar, baz, fizz, buzz"
}
I wrap that inside a private metas method in whatever controller I want to use:
private
def metas
@metas = {
...
}
end
Then call a before filter on it:
before_filter :metas
Then, in my application layout, I have this block:
<% if @metas.present? %>
<% @metas.each do |name, value| %>
<meta name="<%= name %>" content="<%= value %>">
<% end %>
<% end %>
Now, in any controller, I just have to define that metas method and set whatever parameters I want and it will pop up on that page.
There may be a better way to do this, but it seems to work pretty well. Would love to hear suggestions or comments if anyone has them.
