+# Attribute Getter without the Recursion
+
+You may find yourself adding a custom *getter* method for one of the
+attributes in a Rails model. It might look something like this:
+
+```ruby
+def name
+  name || account.name
+end
+```
+
+This method will fall on its face as it quickly expands the stack
+recursively calling itself. Instead, you can tell `ActiveRecord` that you
+want the value of that attribute without invoking the getter
+Instead, we want to get the value of the attribute without invoking the
+model's getter. `ActiveRecord` allows us to do this with the
+[`read_attribute`](http://api.rubyonrails.org/classes/ActiveRecord/AttributeMethods/Read.html#method-i-read_attribute)
+method. Check it out:
+
+```ruby
+def name
+  read_attribute(:name) || account.name
+end
+```
