Rails - Jan 2006 - Undefined method error

Hi everybody,

Small problem. I get this error:

undefined method `all_categories'' for BlogCategory:Class

Code of BlogCategory class is:

class BlogCategory < ActiveRecord::Base

  has_and_belongs_to_many :blog_posts

  validates_presence_of :name
  validates_uniqueness_of :name

  # Return all categories ordered by name
  def all_categories
    find :all, :order => ''name''
  end;

end

I call this function from FrontendController with simple:

@all_categories = BlogCategory.all_categories

As far as I can see there IS an all_categories method in BlogCategory 
class, but from some reason I can''t access it in controller.

Any ideas? I''m totally new to Ruby so I don''t know where to
start (tried
google, but with no luck).

find is a class method.

do

 def all_categories
    BlogCategory.find :all, :order => ''name''
  end;

Hi,

Updated the code with:

def all_categories
  BlogCategory.find(:all, :order => ''name'')
end

I still get the same error...
