# 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
|
|
```
