We can still use the string to store multiple tags, separated by commas, as in the original implementation.\n\nTo ensure uniqueness of tags within the same task, you can modify the Task model as follows:\n\n```python\nclass Task(db.Model):\n    id = db.Column(db.String(255), primary_key=True, default=Task._generate_id)\n    title = db.Column(db.String(255), nullable=False)\n    description = db.Column(db.String(255), nullable=True)\n    completed = db.Column(db.Boolean, nullable=False, default=False)\n    priority = db.Column(db.String(10), nullable=False, default='medium')\n    due_date = db.Column(db.String(10), nullable=True)\n    tags = db.Column(db.String(255), nullable=True, unique=True)  # Add unique=True to ensure uniqueness\n    depends_on = db.Column(db.String(255), nullable=True)\n    recurrence = db.Column(db.String(50), nullable=True)\n    next_occurrence = db.Column(db.DateTime, nullable=True)\n    time_spent = db.Column(db.Integer, nullable=True)\n    parent_id = db.Column(db.String(255), nullable=True)\n    progress = db.Column(db.Integer, nullable=True)\n    assigned_to = db.Column(db.String(50), nullable=False)\n    estimated_minutes = db.Column(db.Integer, nullable=True)\n    created_at = db.Column(db.DateTime, nullable=False, default=datetime.now)\n```\n\nBy adding `unique=True` to the tags field in the Task model, we ensure that each task can have multiple tags, but no tag can be repeated within the same task.","refusal":null,"annotations":null,"audio":null,"function_call":null,"tool_calls":[],"reasoning":null},"logprobs":null,"finish_reason":"stop","token_ids":null}],"service_tier":null,"system_fingerprint":null,"usage":{"prompt_tokens":25159,"total_tokens":25909,"completion_tokens":750,"prompt_tokens_details":null},"prompt_token_ids":null,"kv_transfer_params":null}
