I have a Rails 5 application that will have dynamic content in the header based on the current route. I realize that I can get the route and compare it with something like if(current_page?('/home')) but is this really the best way?

I think using params[:controller], params[:action] or current_page? would be better

You can use named routes with current_page?:

if(current_page?(posts_path))

and 

if(current_page?(post_path(1))

In addition, you can also check the the current path by using request if you're in root path

request.url
   #=> "http://localhost:3000"

request.path
   #=> "/"

Think of initializing your dynamic content in controller's actions. It is the common solution for such things.

For example:

html:

<title><%= @title %></title>

controller:

def index
  ...
  @title = 'Hello world'
  ...
end

Also, you can initialize dynamic content in Rails views using content_for helper method. There is a similar question about this Rails: How to change the title of a page?

If you are sure that you have to set this content in a different place and based on the current route, I advise you to use params[:controller] and params[:action] parameters, although your solution is not bad too.

  • I am in agreement with your solution, I feel like the controller should be concerned with something like this, rather than the view. Thank you. – Drakken Saer Aug 03 '16 at 23:26
