## Quiz Assignment Overrides API

**A QuizAssignmentOverrideSet object looks like:**

```js
// Set of assignment-overridden dates for a quiz.
{
  // ID of the quiz those dates are for.
  "quiz_id": "1",
  // An array of quiz assignment overrides. For students, this array will always
  // contain a single item which is the set of dates that apply to that student.
  // For teachers and staff, it may contain more.
  "due_dates": null,
  // An array of all assignment overrides active for the quiz. This is visible
  // only to teachers and staff.
  "all_dates": null
}
```

**A QuizAssignmentOverrideSetContainer object looks like:**

```js
// Container for set of assignment-overridden dates for a quiz.
{
  // The QuizAssignmentOverrideSet
  "quiz_assignment_overrides": null
}
```

**A QuizAssignmentOverride object looks like:**

```js
// Set of assignment-overridden dates for a quiz.
{
  // ID of the assignment override, unless this is the base construct, in which
  // case the 'id' field is omitted.
  "id": 1,
  // The date after which any quiz submission is considered late.
  "due_at": "2014-02-21T06:59:59Z",
  // Date when the quiz becomes available for taking.
  "unlock_at": null,
  // When the quiz will stop being available for taking. A value of null means it
  // can always be taken.
  "lock_at": "2014-02-21T06:59:59Z",
  // Title of the section this assignment override is for, if any.
  "title": "Project X",
  // If this property is present, it means that dates in this structure are not
  // based on an assignment override, but are instead for all students.
  "base": true
}
```
