That makes so much sense! Thank you for explaining this to me, I did that
and it finally works!
I also changed the variable name to be nums to make things clearer as well.
I am having trouble with inserting the items accordingly in the database,
attached is a photo of a form submission I just did after filling out 3
form instances in one session.
I think it is because of my forloop but I don't understand why.
This is my code:
def postform():
nums = int(request.vars.nums)
inputs = []
update = db.post(request.args(0))
for i in range(0, nums):
inputs.append(db.post.patient.clone(name='%s_%s' %
(db.post.patient.name, i)))
inputs.append(db.post.attime.clone(name='%s_%s' %
(db.post.attime.name, i)))
inputs.append(db.post.age.clone(name='%s_%s' % (db.post.age.name,
i)))
form = SQLFORM.factory(Field('nums', readable=False, writable=False,
default=nums),*inputs)
if form.process().accepted:
response.flash = 'Thanks! The form has been submitted.'
for i in range(0,nums):
db.post.insert(patient=form.vars['patient_%s' % i])
db.post.insert(attime=form.vars['attime_%s' % i])
db.post.insert(age=form.vars['age_%s' % i])
redirect(URL('postlist'))
elif form.errors:
response.flash = 'form has errors'
return dict(form=form)
I don't understand why the forloop would be generated 9 rows instead of 3?
