If the oncreate callback for a SQLFORM.grid sets form.errors to true, the record is not created; similarly, if form.errors.<fieldname> is set to an error message.
However, shouldn't the form for adding the record return, and in the latter case, with the specified fields showing their error messages? In my case, the list comes up instead. Here is my form & callback although there isn't much to them: def add_handler(form): if form.vars.f_Member_ID=='': form.errors.f_Member_ID = "ID required" session.flash = "ID required" return session.flash = "Handler added" form=SQLFORM.grid( db.t_member.f_User==t.f_User, args=request.args[:2], csv=False, searchable=True, deletable=False, details=False, editable=False, oncreate=add_handler, fields=[db.t_member.f_Member_ID, db.t_member.f_FirstName, db.t_member.f_LastName] ) - Scott -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
