Users Variable Documentation (Reimplementation)

Name	Datatype	Description
id	int(11)	Primary key of the entry in table, auto increments by default
username	varchar(255)	User name of the respective user (formerly name)
crypted_password	varchar(40)	Password of the respective user
role_id	int(11)	Role which this user corresponds to FK into ROLES table.  Examples are super_admin, admin, instructor, etc.
password_salt	varchar(255)
name	varchar(255)	Registered full name of the user, e.g., Lastname, firstname (formerly fullname)
email	varchar(255)	Registered email of the respective user.
parent_id	int(11)	Parent of the respective user; corresponding to the user who created this user.  The value of this field is the primary key in the users table for the parent user, e.g., 2 if the parent is the super-admin (username admin).
private_by_default	tinyint(1)	If the user is private by default; essentially Boolean. It seems that this is not used in the system, don't know what it was intended to mean.  Could be removed.
email_on_submission	tiny_int(1)	If user is to be e-mailed when something they reviewed is resubmitted.
is_new_user	tiny_int(1)	Determines whether the user has logged in before; if not, upon login the user should be presented with the new-user agreement.
handle	varchar(255)	A handle is an alternate name by which the user would want to be known, e.g., on the wiki, if this assignment involves writing on a wiki.  This allows the user to appear anonymous.  In the code, this is sometimes known as the "default handle", because users can also create assignment-specific handles.
time_zone_pref	varchar(255)	Timezone that times should be displayed in when the user logs in.
public_key	mediumtext	Public key used for data-encryption by user.  This is used and should stay in the table, though whether the use is meaningful is not clear.
copy_of_emails	tinyint(1)	Whether this user wants to receive copies of e-mails sent for all assignments they are participating in.  This is only implemented for instructors.  Instructors would enable it so they start getting copies of all emails being sent related to their assignments.  It is a way that the instructor can be reassured that emails are in fact being sent.
institution_id	int(11)	id of the institution that the user is associated with
