Confused about the ways to write code for instance variables

debugcn Published at Dev

I am quite confused on how we write instance variables in Rails.

 Posted by: <%= link_to(@item.user.username, store_path(@item.user)) %>
 Price: <%= number_to_currency @item.price %>

vs

Subject: <%= subject_name @item %>

I am just curious what is the difference between (i) subject_name @item and (ii) @item.price?

Is it not supposed to be @item.subject_name?

I would expect that subject_name isn't a variable, but a method. I guess you have a method subject_name defined in one of your helper files that takes an argument - @item in this example.
