How to call a Model Method from a Controller in Rails 3?

Question

In my model I have something like:

class CML < Lead
 def model_method
  #something
 end
end 

and in my Controller:

def recommend
    @var.model_method
    #more stuff
  end

and @var is a CML object, however I keep getting:

undefined method `model_method' for #

Does anyone knows why?

Thanks!

Answer 1

It seems @var is empty at that point

you should use something like (choose one):

@var = Var.find params[:id]
#or
@var = Var.new
#or
@var = Var.create

then you could call your

@var.model_method
