I''m unable to pass a subset of a form''s parameters to another
method
within the same controller. The error message is "wrong number of
arguments (0 for 3)" and there aren''t any parameters listed.
Here''s the controller code:
class InfoController < ApplicationController
def show_actual_forecast_data
# parameters from the form
data_type = params[:datatype]
productnbr = params[:productlinenbr]
start_date = params[:start_date]
end_date = params[:end_date]
detail_or_sum = params[:detail_sum]
@time_search = TimePeriodSearch.new(data_type, productnbr,
start_date, end_date, dtail_or_sum)
if detail_or_sum == "detail" then
if dtype == "actual" then
redirect_to({:action => ''test_page''}, :datatype
=> data_type,
:start_date => start_date,
:end_date => end_date)
end
end
end
def test_page(datatype, start_date, end_date)
@actual_data = Dailytotal.actual_data_sum(datatype, start_date,
end_date)
end
end
Here''s the TimePeriodSearch model:
class TimePeriodSearch
attr_accessor :datatype, :productnbr, :start_date, :end_date,
:detail_or_sum
def initialize(datatype, productnbr, start_date, end_date,
detail_or_sum)
@datatype, @productnbr = datatype, productnbr
@start_date, @end_date = start_date, end_date
@detail_or_sum = detail_or_sum
end
end
Any feedback would be greatly appreciated.

If test_page is an action, then it cannot have any parameters unless those parameters have default values. Either: def test_page @actual_data = Dailytotal.actual_data_sum(params[:datatype], params[:start_date], params[:end_date]) end Or: def test_page(datatype = params[:datatype], start_date params[:start_date], end_date = params[:end_date]) @actual_data = Dailytotal.actual_data_sum(datatype, start_date, end_date) end should work.

Uh... redirect_to does not call another action... It does an http redirect... meaning new request... meaning no args are passed. If you want to call another action in the same controller, just call it... like any other method. b Dan Manges wrote:> On Apr 20, 8:33 am, Paul Bednar <rails-mailing-l...-ARtvInVfO7ksV2N9l4h3zg@public.gmane.org> > wrote: >> I''m unable to pass a subset of a form''s parameters to another method >> within the same controller.

It''s possible to pass parameters using redirect_to to another method in the same controller. Here''s what I did. 1. Fix the redirect_to code. redirect_to :action => "test_page", :aproductnbr => productnbr, :a_start_date => start_date, :a_end_date => end_date 2. Change the test_page method to the following def test_page @actual_data = Dailytotal.actual_data_sum(params[:aproductnbr], params[:a_start_date], params[:a_end_date]) end 3. Ignore the TimePeriodSearch model and @time_search, as they aren''t needed.
