Can someone please help a very eager Rails newbie?


ok, so I am trying to learn the 'c' in crud from a tutorial right
now.  Using the source below, I am loading the action 'new', filling
out a form to create a new record, and submitting the form to save the
record.  The problem comes when I submit the form.  The app generates
an error saying that the method commit= is not defined.  At this
point, I don't know enough about rails to extrapolate meaning from
this weirdness or to know what I should include in this request that'd
help someone to help me.

CONTROLLER:

class PublicController < ApplicationController

  def album_list
    @page_title = 'railstest/public/album_list (Original)'
    @albums = Album.find_by_sql('SELECT * FROM albums;')
  end

  def alt_album_list
    @page_title = 'railstest/public/alt_album_list'
    release_date = '2003-01-01'
    @albums = Album.find(:all,
      :order => 'title, release_date ASC')
    render(:action => 'album_list')
  end

  def show_album
    @page_title = 'railstest/public/show_album (Inspect Album)'
    @album = Album.find(:first)

  end

  def show
      @album = Album.find(params[:id])
      render(:action => :show_album)
  end

  def create
    @album = Album.new(params)
    if @album.save
#      redirect_to(:action => 'show', :id => @album.id)
      redirect_to(:action => 'alt_album_list')
    else
      render(:action => 'new')
    end
  end

  def new
    @album = Album.new
    @page_title = 'New Model'

  end

end
