I've previously found myself in a situation where the options for a
select on my site should have been user-specific. I therefore did
this:
preview = tfs_widgets.Image_preview_widget(
validator=validators.Int,
options=lambda: identity.current.user.preview_options,
And then in my controller, before submitting the form to a template:
identity.current.user.preview_options = [(movie.id, movie.file_name)
for movie in movie_set.movies]
Note that "preview_options" is not actually stored in the tg_user
table in the DB.
Seems to work well enough, although I'm open to criticism :-)
