Setting associations in Rails app

Im a little rusty to Rails and I'm trying to find an appropriate way to set a series of has_and_belongs_to_many associations. I have created a method, which I intend to make private, which sets the associations. 

  def update

    def set_associations
        industriesParams = params[:business][:industry_ids].reject{ |c| c.empty? }
        @business.update(:industry_ids => industriesParams)
    end

        @business = Business.find(params[:id])
        @business.set_associations

  end

In this attempt, I am getting "undefined method `set_associations'" which I don't quite get. But I am also seeking a cleaner way of setting the associations from scratch.

Thanks, in advance.

This should do the work : 

def update
  @business = Business.find(params[:id])
  set_associations  
end

private

def set_associations
  industriesParams = params[:business][:industry_ids].reject{ |c| c.empty? }
  @business.update(:industry_ids => industriesParams)
end

But to make things shorter, you could even write the following :

def update
  @business = Business.find(params[:id])
  industriesParams = params[:business][:industry_ids].reject{ |c| c.empty? }
  @business.update(:industry_ids => industriesParams)
end
