In a multi-tenant platform, where data is shared across different countries and currencies, it's essential to consider the placement of flags like "is this supported by our product?" to ensure consistency and maintainability. This decision can impact how your system handles data and user queries.

💡 Why You Are Getting This Error

  • The flag's placement can affect data security and user experience. If the flag is placed on the data DTO, it may reveal sensitive information about the supported countries or currencies to unauthorized users.

🚀 How to Resolve This Issue

Method 1: Centralized Service

  1. Step 1: Create a dedicated service that handles the flagging logic.

Method 2: Data DTO

  1. Step 1: Place the flag on the data DTO, but use a mapping service to translate the result into the required format.

✨ Wrapping Up

Ultimately, the decision depends on your specific requirements and system architecture. Consider factors like data security, scalability, and maintainability when deciding where to place the flag.
