I have this:

```
      <%-f.fields_for(:clearances, :index => []) do |ff|

            puts ff.object.methods.sort
            if ff.object.newrecord?
              ff_id = "new_"
            else
              ff_id = "show_"
            end

      -%>

```

Which gives me this:

. . .  
metaclass  
method  
method\_missing  
methods  
nested\_attributes\_options  
new\_record?  
nil?  
object\_id  
partial\_updates  
. . .

```
And we follow the new user roles

```

link # features/app/models/  
clearances/step\_definitions/clearance\_steps.rb:14  
undefined method `newrecord?’ for #Clearance:0x2b203e415238  
(ActionView::TemplateError)

So, where does the missing method go between the puts and the if?

newrecord? vs new\_record?

you’re missing an underscore in your code.

newrecord? should be new\_record? instead.
