You’ve created an instance method, but you’re trying to call it as if it was a class method (and you probably meant for city to be the second bind variable in your call to find) Fred ---

– अभिनव [http://twitter.com/abhinav](http://twitter.com/abhinav) Make search a class method, ie, define search like this in your model: def self.search(business\_name, city) # note “self” ## do something end
