Rails
1

hello ,
i have problem when i want to show page after user submit data into
database.
this is code in controller

class ComponentsController < ApplicationController

def index
end

def databases
@title = “Database”
if request.post?and params[:seq]
params[:seq][:sequence].gsub!(/\s/,"")
params[:seq][:sequence].upcase!
@seq = Seq.new(params[:seq])
if @seq.save
flash[:notice] = “sequence submitted !”
redirect_to :action => “show”
end
end
end

def show
@title = “Show”
@seq = Seq.find(params[:id])
end
end
end

when i run i have error like is
ActiveRecord::RecordNotFound in ComponentsController#show
Couldn’t find Seq without an ID
/usr/lib/ruby/gems/1.8/gems/activerecord-2.3.2/lib/active_record/
base.rb:1572:in find_from_ids' /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.2/lib/active_record/ base.rb:616:infind’
/home/apple/www/rcc_eri/app/controllers/components_controller.rb:29:in
`show’

it is not

redirect_to :action => “show”

BUT :
redirect_to :action => “show”, :id => @seq.id

Good Luck,
