Sure:
# news.py model:
db.define_table('news',
Field('category','integer'),
Field('title'),
Field('link'),
Field('comments'),
Field('votes','integer'),
)
# action
def news_create():
db.news.link.show_if = (db.news.category==1)
db.news.votes.default = 0
form = SQLFORM(db.news)
return locals()
# view
{{extend 'layout.html'}}
<h2>New Item</h2>
{{=form}}
It will work with
db.news.link.show_if = (db.news.category==2)
or any value except 1 or 0, even negatives.
If the value is 0 it will not even hide the row.
FYI using web2py 2.9.5
