Rails - how to get category name out of database?

I have a Product which has a has_and_belongs_to_many relationship with a category. I am using simple_form with Twitter Bootstrap integration, in order to generate Checkboxes, that allow to select multiple Categories per Product.

Unfortunately when I ask Rails for "product.categories", what I get is : "[#]"

How can I access the name of this Category? "product.categories.name" doesnt seem to work.

You will get an array of names of categories of product by this: 

product.categories.collect(&:name).to_param

You can get objects of categories

product.categories.each do |category|
  category.name
end

or 

product.categories[0].name #for first category from categories
