Rails: How to display certain characters and dismiss the rest?

When I use 

<%= current_user.name[0,20] %>

it only shows 20 character, as I want.

However, I want to use this approach in another context. I have 

<%= @patient.human_attribute_value(:complaints).html_safe %>

and I want to display only [0,20] characters of this, but I didn't manage. I tried 

<%= @patient.human_attribute_value(:complaints[0,20]).html_safe %>

but it gives me an error.

Can you please help me?

In your context :complaints is a symbol that is sent as parameter. Why do you treat it as a property that returns a value?

Try

<%= @patient.human_attribute_value(:complaints)[0,20].html_safe %>
