[C2] Assignments seem to use wrong dates

[ywarnier]

Currently in C2, if I create an assignment as a teacher and set:

• Expiry date: 01/09/2025 (whatever time, we don't care for this issue)
• End date: 05/09/2025

When I then look at the list of assignments, I get a table with

• Expiry date: 01/09/2025
• End date: 01/09/2025

This seems to come from the fact that the data in this table comes from the CStudentPublicationRepository, which only queries the c_student_publication table, while the real data for the assignments created by the teacher is in c_student_publication_assignment (expires_on and ends_on fields).

This blocks reviewing #3297

Please fix.

Also, a student seems to see all buttons of the teacher inside https://testing25.beeznest.com/resources/assignment/5/submission/1?cid=1&sid=0
This only happens when the end date has expired.

It is checked and fixed the dates with this commit e6b6597

Thanks for confirmation.

Almost OK 😅

• in teacher view, the "Date sent" column does not need to be shown (just remove it)
• in student view, the "End date" must not be shown (it's a secret, internal date)
