how query denote formed off controller name

i've refactoring models controllers an bid mislay formula duplication, distant seems organic creamy. now i've got bit formula common twin controllers, so:

def process_filters
# filter crush we're going pass model
  filter_to_use = {}

  # slight filters, initial query denote out filters
  # should looking for, denote knows filter.
  iso.available_filters.each |filter|
    # should have the array the filter listing.
    # check squeeze method denote description
    filter_name = filter[0][:filter_name]

    # filters stored event variable, proceed filters survive
    # page reloads, etc.  initial thing do, set event new filters
    # have set filter.
    session_name = session_filter_name( filter_name )
    params[session_name]
      params[session_name] == 'all'
        session[session_name] = nil
      else
        session[session_name] = params[session_name]
        filter_to_use[filter_name] = params[session_name]
      end
    elsif session[session_name]
      # params aren't read, still need filter formed off users
      # session
      filter_to_use[filter_name] = session[session_name]
    end
  end

  # only controlling non-static until i refactor supporter code
  # upheld in.
  @current_filter_values = filter_to_use

  filter_to_use[:page] = @current_page

  @isos = iso.find_filtered( filter_to_use )

  @isos.out_of_bounds?
    filter_to_use[:page] = session[:previous_page] = @current_page = 1
    @isos = iso.find_filtered( filter_to_use )
  end
end

now formula accurately same formula another controller, solely denote anxiety (in box iso). there somehow i denote anxiety dynamic?

basically i'ld reinstate iso references (including @iso variable) something formed off controller.controller_name similar.
