For the following code:
<%= link_to "Some Page", some_path %>
How do I apply a css class current
using the current_page?
helper method?
Or if some other better way is available?
In app/helpers/application_helper.rb
def cp(path)
"current" if current_page?(path)
end
In your views:
<%= link_to "All Posts", posts_path, class: cp(posts_path) %>
Basically write a simple wrapper around it. Additionally you could extend the method to allow additional classes to be applied by adding arguments. Keeps the views concise/dry. Or, without extending the method, you could just do simple String interpolation like so to add additional classes:
<%= link_to "All Posts", posts_path, class: "#{cp(posts_path)} additional_class" %>
