Dear Anthony,
You said, And if you need a completely customized form, you can do so by
writing a formstyle function, using form.custom, or with hand-coded HTML.
With the latter two options, if you need to re-use the form code, you can
put it in a template and include it where needed.
Thanks,
Just use pure HTML as usual and (a) make sure the name attributes of form
fields correspond to the names of your database table fields, and (b) at
the end of the form, include the following:
{{=form.custom.end}}
in place of:
/form
form.custom.end includes the two hidden fields used by web2py
when you want only one and the first better use .select(limitby=(0,1)) and
proper orderby, else you can be disappointed by performance...

I have a URL that I want to direct to after login. Something like _next_url

The problem is this. The signature is computed before login. After login,

URL after the fact ... after the URL
I have done some debugging on this by creating a brand new app and trying
to use the same db.py file as my app that's not working. When doing so I
removed some pieces of code I thought might be causing the problem and it
looks like I've narrowed it down.
In the app that I have running in the

You asked, Can you share examples...?.
Here are links to a couple of app pages i remember finding difficult to
achieve using *my *level of understanding of standard web2py techniques,
for the version available at development time. To be sure web2py has
improved since then.

Yes, and even in that case, you can still use .first() to extract that

am looking for a rough idea on how to approach email reply to multiple

Hello all,
I'm creating a new question from a brief conversation I had going on in
this thread: https://groups.google.com/forum/#!topic/web2py/UYqS8nIkeQY.
So basically I have an app that uses nothing but web2py (no wsgi or apache)
and in this app I want to add 2 additional auth tables. One of
rows = db(query).select()
In the above, rows is a Rows object, which acts like a list of Row
objects. To extract a single Row object, you would do:
row = rows[index]
Specifically, to get the first Row, you would do:
first_row = rows[0]
rows.first() is simply equivalent to rows[0], except
Hi Joe,
When I needed to create a custom form, I followed this:
http://web2py.com/books/default/chapter/29/07/forms-and-validators#Custom-forms
I still used the widgets serialized by the web2py model code and only
modified the layout. However, it looks like they have some helpful goodies
in
Do you want a list of all field types? This would do it:
field_types = []
for table in db.tables:
for field in db[table].fields:
field_types.append(db[table][field].type)
However you will have a lot of ids.

Yes!!
That what I thought... I had already db.table.field.type in mind, but
didn't know how to invoque adapter...
Thanks Anthony.

I work around that by just print string of db.table.field.type and write my
model in web2py then generate SQL with an SQL generator app...

This will be all right, I am not writing SQL that much anymore, I let
web2py generate it form me :)

Hello Leonel,
Actually my tables names are prefixed with old postgres schema name so, I
can easily filter the one of interest... Also, the IDs fields don't matter,
since the are prefixed with table name like so tablename_id...
I also change some fields names that are common in many table like
Hoho!
As you mention Anthony, db._adapter.types[] doesn't provide the direct
backend type... You get the type but not the extend of the domain of the
field... Also, notice that in case of web2py decimal db.table.field.type
will be 'decimal(4, 2)' and the key in _adapter.types is only 'decimal'
HI Everyone,

And if you want the actual Postgres field type for a given field, you can
do:

However, you will get back values that include Python string formatting
