Rails error "wrong number of arguments (1 for 0)"

Question

I am using a scope to filter my results :

@hotels = @hotels.type(params[:hotel_type]) unless params[:hotel_type].blank?

with

scope :type, lambda { |type|
  self.scoped.where('hotel_type_id IN ( ? )', type.join(', ')) unless type.blank?
}

And params[:hotel_type] = ["2","3"]

Anyone can help me? I think it's because it's an array but i don't know how to fix this.

Thank you

You should be able pass in type without the join because the SQL escaping should take care of it for you. — tadman

i think you cant name your scope type, i'd name it by_type

Sometimes reserved words sneak up and bite you like this.

Yes, i didn't think so but it seems logical!

Yesterday I tried to name a column 'type' and that didn't work either.

Type is used in single table inheritance to name a attribute in order to use same table for diff classes.
