Project Description

AITrip Planner is a project built using the Django web framework. It follows the Model-View-Template (MVT) architecture where URLs route user requests to views, views handle business logic, and models interact with the database. The project uses forms to process and validate user input, while templates render HTML pages for the frontend. Static files like CSS, JavaScript, and images enhance the user interface. Middleware manages request and response processing, including user authentication. The project uses an SQLite database to securely store user and trip information. This architecture ensures the project is modular, maintainable, and scalable.

Function to parse the AI response

    def _parse_ai_response(self, response_text):  
        try: if isinstance(response_text, dict): return response_text

        response_text = response_text.strip()
        start_idx = response_text.find('{')
        end_idx = response_text.rfind('}') + 1
        if start_idx >= 0 and end_idx > start_idx:
            json_str = response_text[start_idx:end_idx]
            return json.loads(json_str)

        raise ValueError("Could not find valid JSON in response")

    except Exception as e:

        return {
            "day_1": {
                "morning": {
                    "main": "Error generating itinerary",
                    "alternatives": ["Please try again", "Contact support if the issue persists"]
                },
                "afternoon": {
                    "main": "Error generating itinerary",
                    "alternatives": ["Please try again", "Contact support if the issue persists"]
                },
                "evening": {
                    "main": "Error generating itinerary",
                    "alternatives": ["Please try again", "Contact support if the issue persists"]
                },
                "food": ["Error generating restaurant recommendations"],
                "tips": f"Error: {str(e)}"
            }
        }
