Hi,
I'm using sqlos for a zope 3 project using an existing
mysql database. Following the tutorial, I was able to
create a table object as well as a container. I also
had to add a sqlmeta class. Everything works fine
except : 
- when I try to add an object, I get the following
error : Traceback (innermost last):

Yes there is a tutorial included with the source, but I think it's a bit
out of date.

Probably the best way is to look at the functional testing harness, that
is a mini application in it's own right. It is also guaranteed to be
correct.

Probably the best place to ask questions is this list, or #z3-base on
freenode.

I've seen this before and believe it is more an issue with SQLObject
rather than SQLOS. There may be a better response from the SQLObject
docs or list.

I seem to remember that SQLObject is very picky with what the names of
attributes and columns are. This is especially a problem when you try to
use an existing database.

Are you inheriting from SQLOS and Persistent, or pasting into a
persistent container?? Because zope is trying to put your SQLObject into
the ZODB...

Please bear in mind that SQLOS still doesn't work very well through the
ZMI. People have generally been using it for projects where they replace
the ZMI completely.

That is why I declared a sqlmeta class in my class,
the problem only arises with one field, which is
strange. It doesn't have any problem when retrieving
the rows or updating.

I know this might be asked elsewhere, but is it easy
to replace the ZMI ?

I found the answer to the adding problem :
the field was required and there was no default value.
If a default value is added, there is no longer any
problem.

Yeah, it normally happens when the attribute name is different to what
sqlobject expects. I normally haul out the python debugger at this
point, or start printing out SQL (which you can do by setting debug=1 in
sqlos.adapter).

Hopefully SQLObject 2 will be better about this.
