[web2py:31966] Re: Multiple file upload


I've also got a need to support uploading multiple files (perhaps
hundreds at a time) and arranging for each of them to result in a new
database record.  What's the recommended way to do this?
Thanks,
Mike

I'm not sweating over it, but this is still important for me because
my client may later want their GAE app migrated to a personal server.
Also I don't want to be locked into GAE if their service plans change
for the worse.

[web2py:31968] error when the text is long


Hi,

I have a field such as: Field ( 'myField', length = 20).

Hopefully, when someone completes the form, whether to enter text when
you save the framework truncated after 20 characters and not a
failure.

It's a bug?

Jose

Yes, and to be practical, there is not much overhead.  I was trying to
answer the question, what is the efficiency difference between web2py
and GAE Models, the truth is there is so little difference it should
not be a concern.

Like I said, the web2py DAL interface is remarkable in that it can
allow adding all these GAE features, and make it backward compatible
with SQL DAL. (win-win)

-batch get/put/delete
    db(db.table.id.belongs(1,2,3)).select(),
    db.table.insert([{},{},{}]),
    db.table.delete(1,2,3)

-list-properties
 db.table.tags=['a','b','c']
 SQL dal already supports this by joining into a delimited string

-transactions by passing a callable
 row.update(lambda row: row.counter+=1)
 SQL dal would just call the callable, since the request is already a
transaction

-storing keys as fields

db.table.myField.requires=IS_LENGTH(20)
to have it validated.

[web2py:31973] determine if session is new


Asp.net and java have convenience functions for this.  Does web2py? I
can't find it.

Thanks!

No but you can use:

request.cookies.has_key(response.session_id_name)

[web2py:31975] Re: determine if session is new


correction. Try this instead:

response.cookies.get(response.session_id_name,None) !=
response.session_id

is True if the session is new, False otherwise
