Allocation Completeness Report

For each SubjectAllocationStats in semester, check if TeacherSubjectRequest corresponds to TeacherSubjectAllocation.

We need to implement validation to TeacherSubjectAllocation with respect to the TeacherSubjectRequest, CoursePreferences and JoinedSubjectGroup for the teacher and sujbect.

To do so, we need to define interface that will accept all these information and to implement multiple instances that will do the different validation logics. The interface should be:

public interface TeacherSubjectAllocationValidator {
   String validateAndUpdateValidationMessage(TeacherSubjectAllocation allocation);
}

In the implementation methods, the allocation should be updated with appending the validation message on its validationMessages field.

In this task, we need to implement 3 versions of the interface:

• MultipleLecturesValidator adds message if the professor has not selected multiple lectures, but they are assigned to it (checks both lectures and auditorium exercises)
• AuditoriumExerciseValidation adds message if the teacher is professor (not applicable for the assistants), does not prefer exercises , but exercises are allocated
• LabExerciseValidation adds message if the teacher does not prefer lab exercises , but exercises are allocated and they are not consultations

We need a validation button to the admin/subject-teacher-allocation page that will invoke the validation for all TeacherSubjectAllocation by semester. The service should inject List<TeacherSubjectAllocationValidator> validators via constructor injection and for each TeacherSubjectAllocation in the semester we need to invoke the method validateAndUpdateValidationMessage for all injected validators.
