I have a quick question on a problem of mine.
I've done the ONLamp tutorial with scaffolding a recipe etc, and honesly
I didn't get really any wiser. So I decided to try it out on my own
without scaffolding.
However. Now I'm stuck with my edit-form. I need to update a row with
old text in the 'pres' column in the table called 'presentations' in my
database with a new text typed in with a form (in edit.rhtml).
My Edit method gets the 'pres' from the 'presentations'table but it
doesn't update the edited 'pres' with the new text to the database when
the submit button is clicked. I really can't understand why not? What is
wrong with my code?

text_area (and other similar) helpers will make the submitted parameters available as params[:presentation] since that's the name of the object you're editing.
Use if @presentation.update_attributes(params[:presentation])
and you should be fine.
