Added validation for status, priority, and recurrence fields in web forms to prevent invalid database values.
Changes:
TaskUpdateView.post() (line 419):
- Validate status against Task.STATUS_CHOICES before setting
- Validate priority against Task.PRIORITY_CHOICES before setting
- Validate recurrence against Task.RECURRENCE_CHOICES before setting
- Only update fields if value is in allowed choices
- Default to 'none' for invalid recurrence values
TaskCreateView.post() (line 481):
- Validate status, default to 'pending' if invalid
- Validate priority, default to 'medium' if invalid
- Validate recurrence, default to 'none' if invalid
- Prevents creation with invalid choice values
Allowed Choices:
- Status: pending, in_progress, completed, cancelled
- Priority: low, medium, high, urgent
- Recurrence: none, daily, weekly, biweekly, monthly
Security impact:
- Prevents invalid database values from user input
- Maintains data integrity
- Blocks potential business logic bypasses
- Prevents database constraint violations

Added comprehensive authorization checks to prevent users from:
1. Sharing tasks/tags they don't own
2. Modifying tasks/tags that are only shared with them (read-only access)
Changes:
tasks/serializers.py (TaskShareSerializer):
- Added validation in validate() method to verify task/tag ownership
- Users can only share their own tasks and tags
- Prevents malicious users from sharing other people's resources
tasks/permissions.py (NEW):
- Created IsOwnerOrReadOnlyIfShared permission class
- Owners: full access (read, update, delete)
- Shared users: read-only access
- Prevents privilege escalation via shared access
tasks/views.py:
- Applied IsOwnerOrReadOnlyIfShared to TaskDetailAPIView
- Applied IsOwnerOrReadOnlyIfShared to TagDetailAPIView
- Enforces object-level permissions on all update/delete operations
Security impact:
- Prevents users from modifying or deleting resources they don't own
- Prevents users from sharing resources they don't own
- Maintains proper separation between owner and shared access levels
