- | ====== Exercise Groups ====== | ||
- | |||
- | This page describes a minor part of the [[:stats:start]] [[:stats:schema]], namely the exercise groups. It is a part of [[exercise]]. | ||
- | |||
- | ===== Schema ===== | ||
- | |||
- | <code xcend> | ||
- | element groups { | ||
- | element group * id { [ count(./id, ..exercise/students/student/group) <= ./maxSize ] | ||
- | attribute day { "Monday" | "Tuesday" | "Wednesday" | "Thursday" | "Friday" | "Saturday" | "Sunday" } | ||
- | attribute time { string } | ||
- | attribute location { string } | ||
- | attribute curSize { integer [ . = count(../id, ..exercise/students/student/group) ]} | ||
- | attribute maxSize { integer [ . >= 0 ]} | ||
- | |||
- | element tutor * account {[ exists //accounts/account[./account]/tutor[..exercise/id]/group[..group/id] ]} | ||
- | } | ||
- | } | ||

- | ===== Procedures ===== | ||
- | |||
- | ==== Change Attributes ==== | ||
- | |||
- | {{page>stats:proc:changeAttributes (Group)&noheader&nofooter}} | ||
- | |||
- | ==== Tutor Management ==== | ||
- | |||
- | The procedures for tutor management can be directly taken from the [[account]] section. In an OO setting this placement of the method in the ''Group'' class takes the least number of explicit parameters, as the exercise and group ids are implicit. | ||
- | |||
- | {{page>stats:proc:grantTutorRights&noheader&nofooter}} | ||
- | |||
- | {{page>stats:proc:revokeTutorRights&noheader&nofooter}} | ||
- | |||
- | ==== Member Management ==== | ||
- | |||
- | Another example of another association of procedures; The sign up and out procedures for students from the [[exercise]] section could also be offered on groups, as they have the necessary parameters (It is not currently realized like this in the implementation). | ||
