i *think* that it will work with you existing schema. I have postgres setup with 2 databases ( i think that is the right term - i pass the - d <dbname> option to the psql command), and web2py works fine with them. I do all my database migrations manually as well since there are certain upgrades web2py and postgres can't handle. i never fully understood what postgres means by database and schema, so i hope i'm not leading you down the wrong path.
I don't use the numeric type, so i can't offer much help there, sorry. cfh On May 17, 1:41 pm, Jean Guy <jean...@gmail.com> wrote: > That way, the DAL or web2py (I don't know the exact wording to use) will be > able to put data in my table that allready exist in the postgresql schema > where they are? > > An other problem that I am facing is that I use numeric(length, nb decimal) > type of postgresql that type not seems to be supported in web2py actually... > So I looking around to find the better way to work around (ex.: validator > and string type)... > > Johny > > 2010/5/14 howesc <how...@umich.edu> > > > Johny, > > > Perhaps i mis-understand....but you have all your tables already > > created in postgres right? if so, then you can just define your model > > in web2py using the DAL, but set migrate=false for each table.
