Implement configurable authentication for /api/v1/data generic route
#57
Conversation
- Deleted the entire countries_client_provider.dart file - This file was likely an unused example of the individual provider pattern - Its content is now redundant, as the pattern it demonstrated is already explained in comments in other files
- Add requiresAuthentication parameter to ModelActionPermission class - Update modelRegistry to include requiresAuthentication for all actions - Set default value to true for most actions, allowing unauthenticated access only to specific endpoints like remote_config GET
- Add _conditionalAuthenticationMiddleware to check ModelConfig for authentication requirements - Update middleware stack to use _conditionalAuthenticationMiddleware instead of requireAuthentication - Improve code documentation for data route middlewares
- Add IP-based rate limiting for unauthenticated users - Implement nullable User handling for consistent context - Update middleware execution order and comments
… documentation - Update handling of null users in authorization checks - Improve documentation of middleware behavior for public and authenticated routes - Refine error handling for unauthenticated access attempts - Clarify implications of different RequiredPermissionType values
- Add logging to track middleware execution flow - Handle null user scenario for ownership check - Throw exception for misconfigured public routes requiring ownership check - Improve error handling and messaging for configuration errors - Optimize ownership check logic for better readability and performance
- Update authenticatedUser to be nullable to support unauthenticated requests - Add comments to explain user ownership and authentication checks - Refactor user ID determination logic for repository calls
- Update authenticated user type from `User` to `User?` in GET and DELETE handlers - Add check for authentication when updating user content preferences - Adjust user ID retrieval logic for repository calls
Make the getItemPermission for remote_config GET request public by setting its type to RequiredPermissionType.none and requiresAuthentication to false. This change allows unauthenticated access to retrieve remote_config data.

Summary of Changes
Hello @fulleni, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request significantly enhances the flexibility and security of the /api/v1/data generic route by implementing configurable authentication. It allows developers to specify whether a particular model's action (e.g., GET, POST) requires authentication, making it possible to expose certain data publicly while keeping sensitive operations protected. The changes involve refactoring core middleware components to dynamically enforce authentication and authorization rules, ensuring that user context is handled correctly across all data operations, whether authenticated or not.
Highlights
- Configurable Authentication: Introduced a
requiresAuthenticationflag toModelActionPermissioninmodel_registry.dart, allowing authentication requirements to be defined per model and HTTP method for the/api/v1/dataroute. - Dynamic Authentication Middleware: Implemented a new
_conditionalAuthenticationMiddlewarethat dynamically applies authentication based on theModelActionPermissionconfiguration, enabling public access for routes not requiring authentication. - Nullable User Handling: Refactored
authorizationMiddleware,ownershipCheckMiddleware, and data route handlers (routes/api/v1/data/index.dart,routes/api/v1/data/[id]/index.dart) to correctly handle nullableUserobjects, ensuring proper behavior for both authenticated and unauthenticated requests. - Public RemoteConfig Access: Configured the
RemoteConfigmodel's GET item permission torequiresAuthentication: false, making it publicly accessible without requiring a logged-in user. - Rate Limiting Enhancement: Updated
_dataRateLimiterMiddlewareto use IP-based keys for unauthenticated requests and user IDs for authenticated requests, providing more granular and appropriate rate limiting. - Middleware Chain Reordering: Adjusted the order of middleware execution for the
/api/v1/dataroute to ensure_modelValidationAndProviderMiddlewareruns first, followed by_conditionalAuthenticationMiddleware, then_dataRateLimiterMiddleware, and finallyauthorizationMiddleware. - Code Cleanup: Removed the unused
lib/src/providers/countries_client_provider.dartfile, streamlining the project structure.

Code Review
This pull request successfully implements configurable authentication for the /api/v1/data route, allowing specific endpoints like remote_config to be public. The changes are well-structured, introducing a _conditionalAuthenticationMiddleware and updating other middlewares and route handlers to work with a nullable User. My review includes two main points for improvement: first, to address duplicated logic for determining action permissions across two different middlewares, which I've flagged as high severity. Second, to reduce verbosity in the model_registry.dart file by removing redundant property assignments that match default values. Overall, this is a great enhancement to the API's flexibility.
