Thank You Massimo!
Yesterday after I posted my question, I found another post here and went
ahead and do this:
On the image table I defined:
*Field('user_id', db.auth_user, default=auth.user_id, writable=False,
readable=False),*
And then I also defined this:
*db.image.user_id.requires = IS_IN_DB(db, db.auth_user.id,
'%(displayed_name)s')*
That worked like a charm.
I understand there are some differences between the approach I implemented
yesterday and the one you're suggesting. I see that there are additional
fields in the image table created, with the information from the user.
What would be the main disadvantages of using the first method, instead of
the "*auth.signature*" method?
And, the field* image.is_active* was also created, and the value for the
picture I uploaded is *True*. Is that possible to be changed by default to
*False*, for example? What is the use for that field?
Thank you very much for your support!
PD: I found last night your Vimeo account with the tutorials. Very nice. I
watched one and learned how to use the Bootstrap 3 features, I'm playing
with that and the application I'm building is growing fast! I think that,
so far, Web2Py is a really powerful framework and helps you build
applications fast. I'm gonna be around here asking questions a lot, hahaha.
Thanks again.
