Thanks for the suggestion, but I don't have any other forms there. I'm

I have to ask...
Why on earth do you have dynamic columns? Can you tell us more as to why
you *need* this, maybe there is a better way.
You can always dynamically build your db.define_table() statements, the
DAL will migrate them as needed.
SO first, build your dynamic fields in a python list
m
In web2py you can do something like:
# define a table 'meta' that describes another table 'from_meta'
db.define_table('meta',Field('colname'),Field('coltype'))
# make sure it contains something
if not db(db.meta.id>0).count()
db.meta.insert(colname='your_name',coltype='string'))
# define from_m
I'm thinking of switching a site from php to python on web2py, however
I've got a question on its mysql support. I'm trying to figure out
how web2py handles tables where the column layout isn't fixed.
Meaning that it's possible for columns to be created, used, and
deleted by the app while it's run
I am not sure the issue is web2py here. It may be 1) the encoding in
the db should be utf8 and it is not, 2) the data has been stored
incorrecly. web2py does not convert data to UTF8 when extracting from
DB but when inserting only.

First of all thank you for your through tests into the DAL.
I worked into this specific issue and I fixed the discrepancy. It
deserves an explanation anyway. Here is a minimal example to reproduce
the problem:
code
db.define_table('b', Field('b'))
db.define_table('c', Field('d'))
print db()
2 things:
1. i've not observed this limit when running queries on GAE. i've
gotten as many as 14,000 records back when running in the production
environment. though it runs way too slow, and i end up eating up my
30 seconds.
2. somewhere (i can't remember where) a paging technique was suggested
Hi Folks,
I'm not sure why but when I'm using as_dict function in a row element it's
not returning UTF-8 characters an example:
db.define_table('evento',
SQLField('dono','reference auth_user',writable=False,readable=False),
SQLField('paciente', 'reference paciente', label='Paciente*'),
it requires using cursor. DAL select requires fetching all records.
The issue it, can we retrieve more than 1000 records looping over them
using cursor instead of using fetch? I have not tried but my
impression is that there is a tradeoff. we overcome a limitation (1000
records) by requiring more c
I've used it via webapp. Can this somehow be used via the DAL?

Hi Johann,
Make sure to set the content-disposition header if you would like to set
the filename.
Also, the filename extension has to match your content-type or the
browser might reject it, however that depends on the browser.

There are a few issues here.
if the browser asks for a download name depends on the browser
settings, not the server code.
you can only propose a name to the browser
response.headers['Content-Disposition''='attachment;
filename=myfile.csv'
You do not need a view unless you return a dict().

I would do
db(db.question.id.belongs(db(db.keyword.keyword=='this'))._select(db.keyword.question))
(db.question.id.belongs(db(db.keyword.keyword=='that'))._select(db.keyword.question)).select(db.problem.ALL)
It will be faster.

It looks like you can return more than 1000 but in different requests

The SQL I wish to produce is:

((k1.keyword="this") AND (k2.keyword="that") AND

That is, find all questions that have both the keyword 'this' and the
GAE supports accessing beyond 1000 records with the cursor:
