My application has pages of two basic types: forms and tables.
As such, I have two different CSS files, forms.css and tables.css.
In my application layout file (application.html.erb), I'd like to load different stylesheets depending on some sort of flag set in a given view.
For example, <%= defined?(@tables) : stylesheet_link_tag 'tables' ? stylesheet_link_tag 'forms' %>.
The above snippet doesn't actually work, but that's what I'm trying to accomplish?
Any ideas?
You should move this to a before_filter in your controller. Keep the view lightweight.
In the view:
<%=stylesheet_link_tag @foo %>
before_filter in Controller:
before_filter :get_css_file
def get_css_file
@foo = defined?(@tables) ? 'tables' : 'forms'
end
I presume you set @tables in your controller, so you might have to adjust your logic, but you get the idea. In fact you already know if it's a table or form page controller, probably, so you'd basically just be setting @foo directly: @foo = 'tables' etc.
I've just tried a similar thing and it works for me. Your code isn't quite right, perhaps you just need to change it to
<%= stylesheet_link_tag(defined?(@tables) ? 'tables' : 'forms') %>
Your ternary operator syntax is wrong, if that's what you're trying to do. I think you mean this:
<%= defined?(@tables) ? stylesheet_link_tag 'tables' : stylesheet_link_tag 'forms' %>
The question mark (?) and colon (:) changed places.
