ruby count for object attribute

I have a object with the next field:

class Post
 field :repost , type: Integer
 attr_accessible :repost
end

In my controller in action repost, I want increase the counter + 1.

I try:

@post.repost += 1

but I get:

NoMethodError (You have a nil object when you didn't expect it!
You might have expected an instance of Array.

How can I fix it?.
