passing parameters between methods of controller (rails)

i have 2 controllers methods create and show

def create
   @message2 = Message.new(params[:message])
   if @message2.valid?
   @message2 = current_user.sent_messages.create(params[:message])         
      redirect_to @message2.receiver    
    else
      redirect_to :back
    end
end

and

def show

   @message = Message.find(params[:id])
   if [email protected]
     @message.is_read=true
     @message.save
     @message2=Message.new(:receiver_id=>@message.sender, :sender_id=>current_user,:theme=>@message.theme)
   else
     @message2=Message.new(:receiver_id=>@message.receiver, :sender_id=>current_user,:theme=>@message.theme)
   end


end

my form

= form_for(@message2) do |f|

  %p
    Content:
    %br
    = f.text_area :content ,:rows => 5,:id => "text_area",
                :cols => 45

  .actions
    = f.submit

in show view i have form which initialize @message2.content but create action cleans all parameters which I set in show action and sets only content value. How to make my form to append parameters (not to clean old)?

def create
  @message2 = current_user.sent_messages.new(params[:message])         
  if @message2.save
    redirect_to @message2.receiver    
  else
    render :action => :show
  end
end

Here's how your create action should look. This is a commonly used Rails idiom.

It will render the form correctly, because the instance variable is still there.
