[postmodern-devel] postmodern, pg, cl-rdbms
by Attila Lendvai 27 Aug '07

27 Aug '07

hello list, i've recently found postmodern on cl.net, and i was wondering that there seems to be a massive amount of duplication of efforts among the following projects: - pg is a long-time postgresql socket based lib: http://common-lisp.net/project/pg/ - cl-rdbms (our fresh clsql replacement, http://common-lisp.net/project/cl-rdbms/ ) which aims to be a backend independent sql lib, just like clsql, with sexp sql syntax ( see http://common-lisp.net/cgi-bin/darcsweb/darcsweb.cgi?r=cl-rdbms-cl-rdbms;a=… for a quick impression ). it has a single backend for now, based on pg. - and postmodern which is something like a mixture of pg and cl-rdbms we should bring out the best of these... my first impression of postmodern is that it's more modern and better organized code then pg which is good. and to also write actual suggestions besides to this rant, i'd use http://common-lisp.net/project/local-time/ as the date/time abstraction data type. it supports timezones and has a string parser/printer. and fyi, trivial-sockets seems to be a dead project. i've tried to contact the author several times with patches and there wasn't any response; #lisp is on the same opinion. usocket at least welcomes patches, but it's not really important if t-s can already do everything needed. any toughts? -- - attila "- The truth is that I've been too considerate, and so became unintentionally cruel... - I understand. - No, you don't understand! We don't speak the same language!" (Ingmar Bergman - Smultronstället)

[postmodern-devel] How to use auto-id?
by Vamsee Kanakala 11 Feb '07

Hi, I'm not sure how to use auto-id in my deftable statement. I have something like this: (deftable cities () ((id :type integer :initarg :id :accessor id) (name :type string :initarg :name :accessor name)) (:class-name city) (:auto-id t)) However, if I use something like (select-dao 'city) To get the list of all cities, I get this error: The assertion (= (LENGTH POSTMODERN::QUERY-FIELDS) POSTMODERN::N-FIELDS) failed. What am I doing wrong? TIA, Vamsee.
