Yes, I forgot to mention, the dropdowns in the forms are based in the IS_IN_DB
validator attached to each field. So, you will also have to overwrite the
requires attribute of these two fields with a custom IS_IN_BD validator.

By default, the represent attribute of a reference field is based on the
format attribute of the table it references. So, you have two options --
you could either change the format attributes of the auth_user and
auth_group tables:

Thanks, so the use of field_id is important! I tried your first test which
can be written with the proper field_id *m.id.* This Works:

q = cm.ref_company == id_company

Sorry. What I wrote is wrong.
Try this ways:

cm.ref_company.readable = cm.ref_company.writable = False
cm.ref_meeting.requires = IS_IN_DB(db, m.id ,'%(title)s')
q =
m, cm = db.meeting, db.co_meet
q = m.id == cm.ref_meeting
q = q (cm.ref_company == 1)
grid = SQLFORM.grid(q, field_id=m.id, fields=[m.id, m.title])

Also, you might consider shortening the name of

it's a table, so no need for table in the name, and galleries_images

Anthony, the basic recommendation was to use SQLFORM.factory, and that was

OK, If your database table is setup correctly then in the database examples
section you should be able to create a form similar to the one in example
33 for a many to many relationship.
http://web2py.com/examples/database_examples/buy
(
That example doesn't look like a true many-to-many it looks like a
one-to-many. Because in the example it searches for both id's already being
in the many-to-many table and if they are it only updates. Where as a true
many to many you would have multiple entries IE: (1, 1, 20), (1, 1, 40),
I think what you mean to say is that you are are looking for the ability to
make multiple selections in one or more tables using a single form that
allows you create a user record.
So for example a table of users, a table of email address types and a table
of email addresses but the user on

I understand that, but you can also use the database portion to create new
data. That is mainly the part I am talking about.
When clicking database then insert in a table, it would be nice if the
relationships could be linked on that insert. This would make performing
inserts more efficiently.

Look for controller appadmin under your or any other app folder.
I have solved these kinds of concerns with pyramid based applications using
sqlalchemy. However I need to look into the core of how Web2py handles
things to figure out the best way.
Sqlachemy allows you to put everything in:
1) Transactions
2) Sessions
So on submit you first create the parent
web2py wraps each request in a single transaction by default, so if you
make multiple inserts during a request and the request ultimately fails due
to an error, the inserts should be rolled back automatically.
See http://web2py.com/books/default/chapter/29/4#Workflow

This something I would definitely be interested in seeing, as well as
input forms for many-to-many in general (not just admin).
