undefined local variable or method `invoices' for Provider:Class

I'm pretty new to Rails, and I think my app has progressed quicker than my knowledge of Rails/Ruby has ...

I have the following models:

[ -- Begin -- ] class Provider < ActiveRecord::Base   has_many :invoices   has_one :user

  def self.get_invoices     invoices.find(:all)   end end

class User < ActiveRecord::Base   belongs_to :Provider   belongs_to :Consumer

  def invoices_raised     Provider.get_invoices   end

   ...

end [ -- End -- ]

and when I call User.invoices_raised I get this error:

undefined local variable or method `invoices' for Provider:Class

Now I thought that having the "has_many :invoices" line would automatically make the connection and let me access "invoices" like that, but obviously I'm wrong. Anyone care to correct me?

Cheers,

I'm not sure what you're trying to do here, but you're clearly
getting classes and instances confused. I think what you meant to do
is this:

class Provider < ActiveRecord::Base    has_many :invoices    has_one :user end

class User < ActiveRecord::Base    belongs_to :provider # Note the lower case here    belongs_to :consumer    has_many :invoices, :through => :provider

   ... end

Then you can just call user.invoices for a particular user.
