madrazrSRabbelier: Hi08:38
SRabbeliermadrazr: heya!08:38
madrazrSRabbelier: I have a question :P08:40
SRabbeliermadrazr: ask away08:40
madrazrSRabbelier: Say I have a model and I create 2 instances of that model and store those instances in the data store08:40
SRabbeliermadrazr: sure08:40
madrazrSRabbelier: one instance will have values for all the properties, where as the 2nd instance will have values for just 20% of the properties (as in if there are 10 properties, it holds values for just 2)08:41
SRabbeliermadrazr: assuming those values are not required, ok08:41
madrazrwill the 2nd instance consume less storage space in the data store?08:41
madrazrSRabbelier: yeah08:41
SRabbeliermadrazr: hmmmm, yes, I do think it could consume less space, but in practice it'll probably be negligable, why?08:43
SRabbeliermadrazr: 0.47 of 602.00 GBytes08:43
SRabbeliermadrazr: we have quite a bit of storage space left :P08:43
madrazrSRabbelier: ROFL! :D08:44
madrazrSRabbelier: For GHOP tasks we are planning to store the entire history of a task08:45
SRabbeliermadrazr: aye08:45
madrazrSRabbelier: I was thinking of storing them as ChangeSets08:45
madrazrSRabbelier: ?08:45
SRabbeliermadrazr: mhhh, that's an option08:45
madrazrSRabbelier: Lennie also suggested, storing the change as a single field and parsing this field to obtain the history08:48
SRabbeliermadrazr: as a JSON string?08:48
madrazrSRabbelier: can you suggest something?08:48
madrazrSRabbelier: yeah thats possible08:48
SRabbeliermadrazr: that would make gathering statistics harder and easier at the same time08:48
madrazrSRabbelier: easier?08:49
SRabbeliermadrazr: e.g., you can't find out in one query how many students have completed a task, but you can gather _all_ statistics in one go very easily08:49
madrazrSRabbelier: Oh yeah08:51
madrazrSRabbelier: which of these 2 kinds are more often?08:51
SRabbeliermadrazr: mhhh, I think the latter08:52
madrazrSRabbelier: Ok08:52

madrazrSRabbelier: what should scope_path contain if I have to create a dummy organization entity?11:13
madrazrSRabbelier: this question is in context of writing organization logic test11:13
SRabbeliermadrazr: the scope of some test program11:17
madrazrSRabbelier: sorry, was on a call :(11:30
SRabbeliermadrazr: np11:31
madrazrSRabbelier: so it can be some arbitrary string? or should I create a program too?11:31
SRabbeliermadrazr: no, it should be the key name of a program entity (sorry, not scope)11:31
SRabbeliermadrazr: might be good to re-use some code from seed_db to create what you need11:32
madrazrSRabbelier: Ok11:32

madrazrSRabbelier: how do I run the tests I have added now?13:03
SRabbeliermadrazr: ./run.py13:11
madrazrSRabbelier: did the same, but I get this error, "nose.config.ConfigError: Error reading config file 'setup.cfg': no such option 'cover-html-dir'"13:12
SRabbeliermadrazr: you need to install nose 0.1113:12
madrazrSRabbelier: ah Ok13:12
SRabbeliermadrazr: easy_install nose=0.1113:12
madrazrI have install 0.10 from repos13:12
madrazrSRabbelier: will install it13:12
SRabbeliermadrazr: mind updating the wiki13:13
SRabbelier?13:13
madrazrSRabbelier: I will do it13:13
SRabbeliermadrazr: sweet, thanks!13:13
madrazrthis should goto Testing Guidelines Wiki page?13:13
madrazrSRabbelier: NP13:13
SRabbeliermadrazr: mhhhh, should go in some testing related document :D13:14
* SRabbelier is not sure where13:14
madrazrSRabbelier: Ok, thats the only document that talks about tests :P13:14
madrazrso it should go there :D13:14
SRabbelierhehe, maybe make a new one?13:14
SRabbeliermadrazr: GettingStartedOnTests?13:14
madrazrSRabbelier: it already exists, you have created it13:15
madrazrwe need to update it13:15
madrazrI will do it13:15
madrazris it Ok if I do it on that page?13:15
SRabbeliermadrazr: yes please :)13:16
madrazrSRabbelier: Ok cool!13:16
madrazrSRabbelier: this tests is making histories for me :D13:16
madrazrMany first things, this is the first time I ever used easy_install :D13:17
SRabbeliermadrazr: cool! best way to learn new stuff is to use it :D13:18

madrazrhow do I solve this error?15:48
SRabbeliermadrazr: look at how run.py, it should set it16:02
SRabbeliermadrazr: if it doesn't, make it16:02
madrazrSRabbelier: yeah I now just tried with os.environ['HTTP_HOST'] = 'localhost'16:03
madrazrand that error is gone16:03
SRabbeliermadrazr: wooh16:03
madrazrI have a new error now :P16:03

SRabbeliermadrazr: you forgot a .logic16:04
madrazrSRabbelier: for?16:05
SRabbeliermadrazr: or.. you found a bug :P16:05
SRabbeliermadrazr: the error line16:05
SRabbeliermadrazr:     key_name = model_logic.notification.logic.getKeyNameFromFields(fields)16:05
madrazrSRabbelier: latter I am thinking :D16:05
SRabbeliermadrazr: should be model_logic.logic16:05
SRabbeliermadrazr: or at the top16:05
madrazrSRabbelier: Ok16:06
madrazrSRabbelier: import soc.logic.models as model_logic16:14
madrazrThe import statement looks like this16:14
madrazrSRabbelier: so key_name = model_logic.notification.logic.getKeyNameFromFields(fields) should be correct16:14
madrazrbut still the test says module has no attribute notification16:14

madrazrSRabbelier: Ok16:34
madrazrbut I am wondering why that error is occuring16:34
SRabbeliermadrazr: what's your full path?16:34
madrazrSRabbelier: full path to?16:35
SRabbeliermadrazr: to you repo16:35
madrazrSRabbelier: /media/netfs/melange/16:35
SRabbeliermadrazr: and then /tests?16:36
madrazrSRabbelier: yeah16:36
SRabbeliermadrazr: mhhh, weird then16:37
SRabbeliermadrazr: all the tests pass but that one?16:37
madrazrSRabbelier: yeah16:37
madrazrSRabbelier: and the weirdest part is, just replace model_logic.notification with any other logic say model_logic.user this error won't occur16:38
SRabbeliermadrazr: mhhhh, weird, it's working for me :(16:39
madrazrSRabbelier: this is happening for the new test I have written16:39
madrazrSRabbelier: I will mail the patch16:39
madrazrapply and test16:39
madrazrSRabbelier: whenever you are free16:39

SRabbelierdurin42: I hope to be able to help out more with hg-git, but everytime I pick something to fix schacon has already fixed it, amazing! :P17:11
madrazrSRabbelier: I still did not understand what the problem was :(17:12
madrazrSRabbelier: and what did your fix do?17:12
SRabbeliermadrazr: in python, if you do not import a module, it just does not exist in the parent module17:12
SRabbeliermadrazr: try this in an interactive python interpreter17:13

madrazrSRabbelier: tests passed17:22
madrazrSRabbelier: I have not changed anything in the patch sent17:22
SRabbeliermadrazr: yup :D17:22
SRabbeliermadrazr: that's what I saw too17:22
madrazris it possible to review the patch and give suggestion?17:22
madrazrSRabbelier: heh Ok17:22
madrazrSRabbelier: any suggestions for improvement?17:22
SRabbeliermadrazr: can you reuse the org_app properties from seed_db?17:36
madrazrSRabbelier: as in call seed_db.seed_org_app() method?17:37
SRabbeliermadrazr: right, or modify seed_db to let you more easily do that, that'd be fine too17:37
madrazrSRabbelier: Ok17:38
madrazrthat means just have request parameter take a default value as None17:38
SRabbeliermadrazr: mhhh, would be better to just make it not need the request parameter17:38
madrazrSRabbelier: I did not get you17:39
SRabbeliermadrazr: what does it use request for?17:39
madrazrSRabbelier: nothing17:39
madrazrso totally remove request?17:39
SRabbeliermadrazr: mhhh, I think that would break other parts of seed_db17:40
madrazryeah17:40
madrazrso making def seed_org_app(request=None, i):17:41
madrazrworks?17:41
SRabbeliermadrazr: yeah, I guess that'd work for this case :)17:42
madrazrSRabbelier: Ok17:43
*** dhaun has quit IRC17:48
madrazrSRabbelier: if we re-use seed_db's seed_org_app after we get the properties back17:53
madrazrwe will have to manipulate the link_id17:54
SRabbeliermadrazr: how come?17:54
madrazrSRabbelier: link_id of org and org_app needs to same no?17:54
SRabbeliermadrazr: right, but doesn't it use the 'i' value for that?17:54
madrazrSRabbelier: it does, but the way seed_org and seed_org_app constructs link_id is different17:55
madrazrseed_org_app has 'link_id': 'org_app_%d' % i,17:55
madrazrseed_org has 'link_id': 'org_%d' % i,17:55
SRabbeliermadrazr: ah, right, that should probably be changed (org_app should be org)17:56
madrazrSRabbelier: Ok17:56
madrazrSRabbelier: then I think now we can reuse both seed_org and seed_org_app17:57
madrazrshall I ?17:57
SRabbeliermadrazr: yup, go ahead17:57
madrazrSRabbelier: ouch, seed_org_app uses request parameter :)18:04
madrazrstatus = request.GET.get('status', 'pre-accepted')18:04
madrazrSRabbelier: can we still re-use it? any tricks?18:05
SRabbeliermadrazr: yes, do the status extraction in the seed_db code, and pass that to seed_org_app18:06
madrazrSRabbelier: so status is a 3rd parameter?18:08
madrazrto seed_org_app18:08
SRabbeliermadrazr: instead of request18:09
madrazrSRabbelier: I did not get this, please explain a bit18:09
SRabbeliermadrazr: sorry, was looking up The Law of Demeter on statckoverflow :P18:23

SRabbeliermadrazr: we're almost-but-not-quite violating it there18:25
madrazrSRabbelier: stackoverflow is freaking fast :P18:25
SRabbeliermadrazr: but the idea is the same18:25
SRabbeliermadrazr: yes, it is, it's amazing18:25
madrazrSRabbelier: Ok18:25
SRabbeliermadrazr: instead of doing foo(request) and then in foo have request.GET.get('status', 'pre-accepted')18:26
SRabbeliermadrazr: we should extract that value before calling foo, and then pass it as argument18:26
madrazrSRabbelier: but that breaks other parts of seed_db no?18:26
SRabbeliermadrazr: well, that's the point, you need to fix those calles :P18:27
SRabbeliermadrazr: should only be one though18:27
madrazrSRabbelier: Ok18:27
