Hi,
I have a problem with checking whether the file upload field in the
database is empty or not.
In the code mentioned below, the user can either upload a file or submit
the form without uploading a file.
If the user uploads a file then the " makeThumbnail" function should be
called. Otherwise it shouldn't be called.
The statement like if db.orders.pic_upload !="": is not working. What is
the right way of achieve this ? Thanks in advance!!
My Model
------------------------
db.define_table('orders',
Field('item_type' ,type='string',default='--'),
Field('pic_upload' ,'upload',autodelete=True),
Field('thumb','upload',writable=False,readable=False,autodelete=True),
auth.signature
)
My Controller
--------------------------
form = SQLFORM(db.orders)
if form.process().accepted:
if db.orders.pic_upload !="":
makeThumbnail(db.orders,form.vars.id,(175,175))
else:
response.flash = 'form has errors'
Best Regards,
Arindam
