User model: username format method

Ok, so in my user model i have created get_username in an attempt to format the username.

The idea is to be able to use

TheUser.get_username

and it would correctly format the username based on user level (admin). As a test I created this:

  def get_username 
    fname = '<span style="color:red">John</span>'
    fname
  end

However, it displayed the value literally with the code showing..

How would i be able to plug the username in as well as display correctly

The Model is not supposed to create the html. You do that in the views. May I suggest another approach instead:

I suppose, you got some variable to store the user_level. Use this in the view like so:

# .ERB-File
<span class="<%= user.user_level %>"><%= user.user_name %></span>

Now format it with css:

# .css-File
span.normal_user {
  color: green;
}
span.admin {
  color: red;
}

PS: I'm not sure about the ERB-Syntax (I use haml).

You can use html_safe.

 def get_username 
   fname = '<span style="color:red">John</span>'
   fname.html_safe
 end

To get the user_name use:

def get_username 
  fname = "<span style='color:red'>#{user_name}</span>"
  fname.html_safe
end

Note that this is very bad code, not only is this abusing the seperation of responsibilty of MVC it also may introduce security vulernabilities.

Code like this should be in view or a helper.
