Create "prod" environment

Separate ports based on from which branch application is run

[yoowon90]

Created database_dev.db and database_prod.db. Flask uses ports 5000 and 5001, respectively. Have not tested ORM Models (not sure what it is or if it is needed). Have not tested merging according to ChatGPT's advice:

Handle Missing Columns: Ensure that your application code gracefully handles missing columns when querying database_prod.

Use SQLAlchemy's Column object with nullable=True for new columns that may not exist in database_prod. Use try-except blocks or conditionals (hasattr()) to check for the existence of columns before accessing them. python sample code

try:
    # Example query in prod environment
    result = ModelProd.query.filter_by(id=1).first()
    if result and hasattr(result, 'new_column'):
        # Process if the new column exists
    else:
        # Handle case where new column doesn't exist
except Exception as e:
    # Handle exceptions gracefully
    print(f"Error: {e}")
