407b1e91 19 * Assess a submission or view the single assessment
0968b1a3 20 *
407b1e91
DM
21 * Assessment id parameter must be passed. The script displays the submission and
22 * the assessment form. If the current user is the reviewer and the assessing is
23 * allowed, new assessment can be saved.
24 * If the assessing is not allowed (for example, the assessment period is over
25 * or the current user is eg a teacher), the assessment form is opened
26 * in a non-editable mode.
27 * The capability 'mod/workshop:peerassess' is intentionally not checked here.
28 * The user is considered as a reviewer if the corresponding assessment record
29 * has been prepared for him/her (during the allocation). So even a user without the
30 * peerassess capability (like a 'teacher', for example) can become a reviewer.
