Insert code inside string [duplicate]

Question

I'm new to RoR. I'm trying to print the string of the current user name logged in inside the string 'Logout' to personalise the message, but I can only get a print of the code...

<% if user_signed_in? %>
      <%= link_to('Log out #{current_user.first_name}', destroy_user_session_path, :method => :delete) %>

Any help would be appreciated!

Thank you.

use double quotes for the string

Use double quotes when you have to interpolate

<%= link_to("Log out #{current_user.first_name}", destroy_user_session_path, :method => :delete) %>

(Sure, it's a dupe, but that's not a valid reason to downvote a correct answer.)

Thank you! This worked. I'm not very familiar with ROR terms yet (string interpolation) to formulate the exact question. +++

@DaveNewton what was the comment about. I didn't get that

Someone downvoted your answer, which was improper behavior.

try this,

<%= link_to("Log out #{current_user.first_name}", destroy_user_session_path, :method => :delete) %>

you can't use interpolation with single-quoted string. Instead you can use double quotes.
