Rails - Apr 2006 - Two forms for two models - one page

I''ve got two forms for two different models on the same page. What I 
want is for one of the forms to return you to the same "new" page and 
not clear the data in the other form.  I was hoping it would be as 
simple as render :action => ''new'' but no such luck.

Any thoughts?

Thanks,

Adam

Ok, the problem is that, when you submit one form, the application does 
not get the data from the other form, so it cannot store it (in the 
session).

I see 2.5 possibilities:

#1: Unify the forms
#2.1: Use JavaScript to duplicate the entered text into hidden fields, 
so form1 will submit the data from form1 and form2 and vice versa
#2.2: Use AJAX to periodically update the contents of the forms and save 
them in the session.

Really, just stick the forms together. If, say, model A''s
"form" is not
changed, then it won''t affect the database. It will be way easier than 
trying to use JS/AJAX or anything like that.

Ah! That makes sense. Thanks.

This works, but I can''t help but feel that it should be simpler...

  def create

#this seems to be the only way to test whether a tag needs to be created
    unless (params[:tag][:name]) == ""
      @tag = Tag.new(params[:tag])
      @tag.save

#without this line the tag field will still have text in it.
      @tag = Tag.new

#and without these I get an error, because render :action doesn''t run 
the controller action. Right?
      @show = Show.new(params[:show])
      @show.tags = Tag.find(params[:tag_ids]) if (params[:tag_ids])
      @tags = Tag.find_all
      render :action => ''new''
    else
      @show = Show.new(params[:show])
      @show.tags = Tag.find(params[:tag_ids]) if (params[:tag_ids])
      @show.save
      @show.user = session[:user]
      if @show.save
        session[:user].shows << @show
        flash[:notice] = ''Show was successfully created.''
        redirect_to :action => ''list''
      else
        @show.destroy
        @tags = Tag.find_all
        render :action => ''new''
      end
    end
  end

Oops, this is wrong:
> #and without these I get an error, because render :action doesn''t
run
> the controller action. Right?
Without the @tags assignment I get an error, because the page for
"new"
calls @tags. Without the @show assignments I just get empty data fields.
