[drupal-devel] Request for input on Quiz module data structure [long]
by Angie Byron 13 Oct '05

13 Oct '05

Hi, folks. Hope that this is the right place for this. Apologies in advance for the length, but I wanted to make sure everyone's on the same page before asking for feedback. == BACKGROUND == As most know, I worked over the summer on the Quiz module. Thanks to a generous injection of funding from Ejovi Nuwere at SecurityLab.net, I've been able to both complete most of the work that was not done by the other student assigned to this project during SoC, and am also able to now focus on adding additional features to the module. The quiz module was developed around Robert Douglass's specification (which I've temporarily mirrored here: http://drupaldev.snarkles.net/node/2) In a nutshell, this means rather than creating a simple module that could do multiple choice questions, instead creating a quiz *framework* which could potentially support almost limitless question types, from traditional multiple choice/fill in the blank, to really innovative ideas such as "reading" a question aloud to gage reading comprehension and so on. == HOW IT CURRENTLY WORKS == The current schema can be viewed here: http://cvs.drupal.org/viewcvs/drupal/contributions/modules/quiz/quiz.mysql?… For the more visually inclined, I've uploaded an E-R Diagram here: http://www.webchick.net/soc/quiz.module/quiz-schema-old.png This is based off the original proposal, where serialized arrays (/me ducks in advance) are used to store answer, feedback and user response data. NOTE: Skip to "THE PROBLEM" if you don't care about how this stuff is stored currently :P A typical result array (stored in quiz_results.results) might look like: Array ( [10] => Array ( [input] => Array ( [0] => 0 [1] => 2 [2] => 3 ) [feedback] => Array ( [0] => Correct! [1] => Correct! [2] => Correct! ) [score] => 1 ) [6] => Array ( [input] => Array ( [0] => 2 ) [feedback] => Array ( [0] => Nope, fooled you! ) [score] => 0 ) ... ) The array keys (10 and 6) are question node IDs... in other words, this is how the user responded to both question 10 and question 6. Over the course of the quiz, this array keeps growing, with one array of results per question. "input" is an array of the answer(s) that the user selected on that question. The first question was a multiple choice question, so the user plugged in three answers (answers 1, 3, and 4 -- remember that arrays start at 0 index). The second question was only a single-choice question, and the user selected answer 3. "feedback" is an array of the feedback to the answer(s) the user selected for input. As you can see, the user answered correctly on all three answers on the first question, but did not answer correctly on the second question. Finally, "score" is either a 1 (indicating the answer was correct) or a 0 (indicating the answer was not correct). == THE PROBLEM == The question was raised to me: "If there's a million questions, and a million students, and we want to find out for a given question, how many student got it right how do we do that?" Right now, the answer is something along the lines of this: ----------------------------------------------------------------------- function get_question_results($quiz_nid, $question_nid) { // Array to store question results $question_results = array( 'right' => 0, 'wrong' => 0 ); // Grab a list of the results array for each quiz attempt $quiz_results = array(); $results = db_query("SELECT r.results FROM {quiz_results} r WHERE r.quiz_nid = %d", $quiz_nid); while ($result = db_fetch_object($results)) { $quiz_results[] = unserialize($result->results); } // Now, loop through each result and look for the given question foreach ($quiz_results as $key => $value) { if ($value[$question_nid]) { // If question is found check if it was answered correctly or not if ($value[$question_nid]['score'] == 1) { $question_results['right']++; } else { $question_results['wrong']++; } } } return $question_results; } // Call the function and output results $results = get_question_results(12, 10); echo $results['right'] ." students answered this question right, " . $results['wrong'] ." answered it wrong."; ----------------------------------------------------------------------- This is quite processor and RAM-intensive, since it has to load ALL of the results for each attempt on a given quiz first, then parse through those to find individual question attempts, and then finally retrieve the answers from each and evaluate whether or not they were correct. And this same basic logic has to be completed for each potential query someone might want to throw at it.. Such as, "What is the average score of this user among all exams?" In short, it doesn't look like this solution is going to be very scalable in the long-term for the kind of ad-hoc querying that educators are likely going to really want to be able to do. == THE SOLUTION? == I've created an alternate, normalized data schema and wanted to get your feedback on it, if you get a chance. http://webchick.net/soc/quiz.module/newschema.sql E-R Diagram: http://webchick.net/soc/quiz.module/quiz-schema-new.sql Changes: - quiz/quiz_questions tables stay the same - multichoice turns into 'quiz_question' containing only a primary key and a "properties" field to take the place of "multiple_answers." I envision this field as being more flexible than multiple_answers, as it could potentially store a plethora of options for very diverse array question types, perhaps in the form of key/value pairs or something (multichoice=1;email_results=1; etc.) - answers are now broken out into a 'quiz_question_answer' table, which links back to quiz_question with separate fields for answer, feedback, and points. The answer field itself could store a wide variety of options, such as "Answer" for a multichoice question, "St. Paul|Saint Paul" for a fill-in-the-blank question, and so on. Since answer display is handled in each question type module in the _form and _render_question hooks, we can still have the advantage of storing data independently from the actual quiz module. Feedback, too, can be stored in whatever way makes sense for the answer, and points can indicate whether a question is incorrect (0 points) or can also be used for 'weighting' questions (answer 1 is 20 points, answer 2 is 50 points, etc.) - Results are now stored in two different tables: quiz_result for the overall properties (start time/end time, etc. -- essentially the same as the current table) and quiz_question_results which provides the textual representation of what that user put for his/her answer on each question attempt. This could be stored in a similar manner to the answers table... for multiple answer questions, it could be 23,63,3 to indicate the answer ids selected, for fill-in-the-blank it could have 'Minneapolis', etc. Each question type's _evaluate_question hook would take the data from the answer field and check it against the given question's answers. - Fields representing times and dates are switched to DATETIME instead of INTEGER (for UNIX timestamp) in order to help with date range calculation And if you made it through that, a hearty congratulations. :P Any thoughts?

[drupal-devel] hard coded page sizes
by David Reed 13 Oct '05

13 Oct '05

I have a use to expose some of the admin type pages (logs, users etc) in a view with limited space available. I noticed that the page size is hard coded in all modules that use drupals paging mechanism. A quick glance reveals the following hard-coded pages sizes: watchdog = 50 lines user = 50 lines statistics = 30 lines comment = 50 lines poll = 50 lines I think it would be really usefull to provide a mechanism to override these hard-coded values. I would suggest something simple like apending a value to the url in the query string for page size. This value could be interogated by each module that calls theme_pager_link() to see if it should use it's hard-coded default or use an override. I'm more than happy to provide some patches for this but I wanted to make sure I wasn't missing a far easier way to solve this issue. Does anyone else see value in this? Is there a better way to do this other than patching the core modules?

Re: [drupal-devel] Improvements abandoned?
by Richard Archer 13 Oct '05

13 Oct '05

Steve raises an issue that has really been bugging me this week. There are currently 260 or so patches in the Drupal issue tracker. Lots of these are worthy patches... like the two Steve mentioned. But so many of them have little or no chance of being reviewed and applied. There must be dozens of people beavering away making improvements to Drupal and submitting patches only to have them get lost in this ocean of issues. Such a waste of resources. Something needs to be done to address this issue. I have looked through the issues tracker reading the comments and following the progress over time of quite a few issues. It's actually quite sad to see a patch get written, reviewed, finalised and then not committed only to see the issue revived 6 months later, the patch gets updated, reviewed, approved and not committed. 6 months later the issue gets revived by someone else bitten by the same bug. What can we do about it? I would like to see ten or so issues at a time nominated as "hot" issues which are targetted, resolved and committed. I think that by focusing on just a few issues at once that these ones will get completed and all Drupal users will benefit from these incremental improvements. These need not be big patches or implementations of extensive new features. Small patches like Steve's help text improvements are just as worthy of inclusion as a new forms API - and a whole lot simpler :) There just needs to be some mechanism to focus resources on a small subset of patches so that they get reviewed, approved and committed. ...Richard.

[drupal-devel] fine grained permissions (was Re: [drupal-docs]Permissions page)
by Kobus Myburgh 13 Oct '05

13 Oct '05

> Larry triggered something that I had bubbling in my mind for a long time > already: finer grained permissions. We can learn something here from large companies (such as Novell). As other Novell admins out there would know, you have file system rights and NDS object rights. Taking only file system rights, any file or folder have the following rights: read, write, create, file scan, erase, access control, supervisor and modify And that is only for file system. It sounds daunting, but still they manage to do this without cluttering the interface (too much) with the ConsoleOne application. Maybe someone should undertake a study on how an approach like theirs could be mimicked in Drupal. Regards, Kobus

[drupal-devel] fine grained permissions (was Re: [drupal-docs] Permissions page)
by Bèr Kessels 13 Oct '05

13 Oct '05

oi. Larry triggered something that I had bubbling in my mind for a long time already: finer grained permissions. On Thursday 13 October 2005 02:16, Larry Garfield wrote: > 2) Permissions not fine-grained enough (does "Create" include "change"?) > I agree completely. We definitely need more fine-grained and descriptive > permissions. There have been several threads about this recently, but not > much code. (I wish I had time to write some.) The hard part is finding > some standard other than "administer", which is a useless word. What I have in mind is something to introduce a parent/child relation in permissions: hook_perm() { $perms[]->title = 'change book pages'; $perms[]->parent = 'create book pages'; return $perms; } means that 'change book pages can only be set true in admin if that role has "create book pages" perms. I am not referring to the permission on check time: only in the permissions administer page: the checkboxes would be greyed out for the permissions that cannot be set. This will allow for a much finer grained permission handling, but will immediately solve some of the clutter. Think about flexinode, for example, where some people would love a per-field permission.

by Steven Peck 13 Oct '05

13 Oct '05

I am working on a Drupal.org readme which I will post on my scratch site for Doc team review (hopefully soon) that will have this information. Essentially a brief overview readme to how to use the Drupal.org site/community. Mainly links and short instructions. Kind of a help text for the site.... Which is odd, but the sheer volume of information available and customs followed on the site/lists/etc are obviously overwelming. -sp > -----Original Message----- > From: drupal-devel-bounces(a)drupal.org > [mailto:drupal-devel-bounces@drupal.org] On Behalf Of Karoly Negyesi > > On Tue, 11 Oct 2005 14:29:04 +0200, Steve Dondley <sdondley(a)gmail.com> > wrote: > > > What happened to having the bug reports and updates getting > mailed to > > this mailing list? > > http://drupal.org/project/issues/subscribe > > This was advertised here.

[drupal-devel] Getting going on regions for 4.7
by Nedjo Rogers 13 Oct '05

13 Oct '05

Multiple regions opens up a lot of space for creativity--but we'll need to get going if we're going to take advantage of the possibilities. I've created a forum topic on getting going on implementing multiple regions: http://drupal.org/node/33899. It includes a link to a good tutorial by Khalid.
