Ruby on Rails. Store variables in text field DB

Question

How I can store ruby string with variables in DB? For example I have model Stack and attribute welcome_message. I want store in welcome_message next string - "Hi, #{user}. How do you do?" Then I make:

user = "artem"
p stack.welcome_message

and got-

"Hi, \#{user}. How do you do?"

I can't fixate it in view, because I want change position varibles in field.

store you welcome message like this

Hi, <user>. How do you do?

and then, while displaying,

user = "artem"
p stack.welcome_message.gsub('<user>', user)

Its like adding a placeholder for user name.
