How can I access to assets/image

Question

I do have the image called 18.png in assets/images/languages/

then I do have the attribute called language
Assuming, current_user.language = 18

How can I access and show the image in view?

Answer 1

Simply append the users language attribute to a relative language asset path inside your view.

<%= image_tag "languages/#{current_user.language}.png" %>

If this is something you're going to be using throughout your application you should move it into a helper method, eg :

def user_locale_tag
  image_tag "languages/#{current_user.language}.png"
end

In your authentication system you'll want to ensure that current_user exists before hand.
