Hello
Is it possible to create a validator for form field that is a combination
of IS_IN_SET and a user write in? The field is of type string.
db.nalogi.n_company.requires = IS_IN_SET(['Canon', 'HP', 'Xerox',
'Lexmark', 'Brother', 'Konica/Minolta', 'Kyocera', 'Other'],
zero=('Select'))
Thank y
*Val K*, it is my table.py file:
db.define_table(
'recipes',
Field('NAME',length=512),
Field('IMAGE','upload'),
migrate=False
)
It's code in my default.py file:
row = db().select(db.recipes.IMAGE).first()
image = str(dir(row))
>>>
['IMAGE', '__bool__', '__call__', '__class__', '__c
Set field type to 'upload' as Ramos suggests and
in your first example it should be row.IMAGE instead of row.file

I think you figured out the important st
Hello! I can get image like that:
import codecs
base64_data = codecs.encode(row.recipes.IMAGE.read(), 'base64')
base64_text = codecs.decode(base64_data, 'ascii')
image = '' % base64_text
Thank all!

I'd look at implementing datatables.net to do that.

Hi, why doesn't work good with first() ?
if you do: db(db.table.xx==request.vars.xx).select().first() it will
return just the first record, if it doesn't is because the record does not
exist.
other way to do this is with limitby:
db().select(db.person.ALL, limitby=(0, 2)):

Ola , estou tentando fazer uma busca no banco usando db(db.table.id ==
request.vars.id).select()
só que esse select retorna uma lista/rows dai queria saber como retornar
apenas um item, ja tentei usar o .firts() mas não ta funcionando direito
alguem teria alguma ideia

Here is an example. I think this is a problem:
>>> from gluon.serializers import json
>>> json(decimal.Decimal(123.456))
'"123.45600030695446184836328029632568359375"'
I think this is what a user would intend:
>>> json(float(decimal.Decimal(123.456)))
'123.456'
*Suggestion:*
In *gluon
