if boolean == false syntax error

I can't get the following syntax to work: 

if document.anonymous == false ?

I get this error: " syntax error, unexpected tIDENTIFIER, expecting keyword_do or '{' or '(' "

Here is the corresponding field for "anonymous" in the document model

field :anonymous, type: Boolean, default: true

Thank you in advance!

Anyone looking at this now, for booleans you can simply use:

document.anonymous? - returns true for boolean with value 1

!document.anonymous? - returns true for boolean with value 0

either use 

if document.anonymous == false #OR unless document.anonymous

else

end

OR 

document.anonymous == false ? () : ()

Note:- In Ruby only false and nil are falsey. Ref this

There should not be question mark. Use this

if document.anonymous == false

Try unless document.anonymous in stead of if document.anonymous == false ?
