Original Pull Request: https://github.com/langgenius/dify/pull/27675

State: closed
Merged: Yes

Summary

This PR introduces a CloudPlan StrEnum to replace hardcoded user plan string literals throughout the backend codebase, improving type safety and maintainability.

Changes:

  • Created api/enums/cloud_plan.py with CloudPlan enum (SANDBOX, PROFESSIONAL, TEAM)
  • Used Python's auto() for automatic lowercase value generation
  • Replaced hardcoded 'sandbox' strings with CloudPlan.SANDBOX in 18 production files
  • Updated 4 test files for consistency
  • All existing tests pass, lint and type checks pass

Benefits:

  • Type Safety: Compile-time checking prevents typos and invalid plan values
  • Maintainability: Centralized plan definitions in one location
  • Code Clarity: Explicit enum members are more self-documenting than string literals
  • Consistency: Ensures uniform plan identifiers across the codebase

Fixes #27674
