Version 2.1 to 2.2 Updates

July 23, 2010

compass:

ALTER TABLE `personalizes` ADD INDEX ( `user_id` , `attribute_code` ) ;

August 18, 2010

To speed up the AjaxList for Users (~300x speed-up with 3000 users database). - Serge.

CREATE INDEX user_id_index on user_enrols(user_id)

September (?)

To allow unlimited comments in evaluation_mixevals. - compass & serge

ALTER TABLE `evaluation_mixeval_details` MODIFY COLUMN `question_comment` TEXT DEFAULT NULL;

Version 2.0 to 2.1 Updates

June 16, 2010

This change was made for student's survey evaluation submissions. Since students submitting surveys are not tied to groups, their group values will be should NULL. Before, the default value for grp_event_id was zero, and, because of the relationship grp_event_id and submitter_id (onl one pair is allowed), the effect was that a single student could only submit one Survey, ever. This change remedies the situation, and no code needs to be changed to accommodate it. - Serge & Pan

ALTER TABLE `evaluation_submissions` MODIFY COLUMN `grp_event_id` INTEGER  DEFAULT NULL;

July 9, 2010

This change is made for student's rubrics evaluation submissions. Since students submitted rubric evaluations are not tied to the rubric, deleting a rubric does not fully remove students' evaluation data of that rubric. With the added 'rubric_id' field, the linkage is now complete and references would not be lost in the relationship specified between evaluation_rubrics and rubric tables. - Henry

ALTER TABLE `evaluation_rubrics` ADD COLUMN `rubric_id` INTEGER DEFAULT 0 NOT NULL;

July 16, 2010

Sets up the new System function code, to match the users controller. - Serge

UPDATE sys_functions SET function_code='USERS' WHERE function_code='USR';

July 22, 2010

Add index for user_enrols table to improve the query time

ALTER TABLE `user_enrols` ADD INDEX ( `user_id` );
