<div dir="ltr">Hi Ivan! What database do you plan to use? Is it SQLite, PostgreSQL or something else? When you loading your info from "xls" files, what do you expect to do with these data? Is it intended to be stored in the database for a long time, or do you just want to temporary load information to the database, process it and then store result somewhere else? </div><div class="gmail_extra"> <div class="gmail_quote">On Sun, Mar 15, 2015 at 11:13 PM, Ivan Evstegneev <<a href="mailto:webmailgroups@gmail.com" target="_blank">webmailgroups@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hello, First of all, I'm absolutely new to DBs and relatively new to Python )))). But got my work to do (EE student project). So please don't blame me for incorrect terminology. My question is simple (at least it seems so to me ^_^): Is it possible to create a dynamic classes with pony_orm? Something similar to this: <a href="http://stackoverflow.com/questions/2827623/python-create-object-and-add-attr ibutes-to-it" target="_blank">http://stackoverflow.com/questions/2827623/python-create-object-and-add-attr ibutes-to-it</a> or this: <a href="http://code.activestate.com/recipes/52308-the-simple-but-handy-collector-of- a-bunch-of-named/?in=user-97991" target="_blank">http://code.activestate.com/recipes/52308-the-simple-but-handy-collector-of- a-bunch-of-named/?in=user-97991</a> By "dynamic" I mean that class attributes are not static. For instance, let's say I have some "node.xls" file which contains some table as this one: param1 param2........ parmaN element1 value 1 value2...........valueN element2 value 1 value2...........valueN . . element value 1 value2...........valueN So I might define a class in pony_orm which will be called as Node() and would include all those (param1 to paramN) and then just assign their values. But this is a static way. What happens when I'll ( at some time) add param(N+1) into my "node.xls"? So in such case I would need to redefine Node() class. Sounds not so hard task to do... But if there some more "xls" files and more params will be added over time to each one of them... I would definitely get into trouble, by spending all my free time to actually make it up-to-date. Hope my question clear enough. Any provided help(ideas, code snippets of possible realization, links etc.) will be highly appreciated. Thanks a lot in advance, Ivan. _______________________________________________ ponyorm-list mailing list <a href="mailto:ponyorm-list@ponyorm.org">ponyorm-list@ponyorm.org</a> <a href="/ponyorm-list" target="_blank">/ponyorm-list</a> </blockquote></div> </div>
