Verified usage

Verified import paths — ran on the pinned version, not inferred.

FeatureManager

✓ from featuremanagement import FeatureManager

Import from featuremanagement directly, not from submodules.

FeatureFilterEvaluationContext

✓ from featuremanagement import FeatureFilterEvaluationContext

Correct import path.

Basic usage: create a FeatureManager with a dictionary of flags and check if a feature is enabled.

from featuremanagement import FeatureManager # Initialize with in-memory feature flags feature_manager = FeatureManager(feature_flags={ "Beta": { "enabled": True } }) # Check if a feature is enabled if feature_manager.is_enabled("Beta"): print("Beta feature is enabled") else: print("Beta feature is disabled")

Debug

Known issues

gotchaFeature flags dictionary must follow the correct schema: each flag must have an 'enabled' key (boolean) and optionally 'conditions'.

fix

Ensure your flag dictionary structure matches: {"FeatureName": {"enabled": True}}.

affects: >=2.0.0

gotchaThe library expects feature flags in a specific format when using Azure App Configuration; mismatched structure can cause silent failures.

fix

Use the Azure App Configuration provider to load flags automatically, or manually parse flags to match the expected schema.

affects: >=2.0.0

deprecatedThe method 'is_enabled' is stable but some older documentation refers to 'is_enabled' with a different signature (without the user context).

fix

Ensure you pass the correct arguments: is_enabled(feature_name, user_context=None).

affects: >=2.0.0

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'featuremanagement'

The library is not installed or the Python environment is incorrect.

fix

Run 'pip install featuremanagement' in the correct environment.

AttributeError: 'FeatureManager' object has no attribute 'is_enabled'

Typo or older version without 'is_enabled' method.

fix

Use FeatureManager from featuremanagement 2.0+, which includes 'is_enabled'. Check your installed version with 'pip show featuremanagement'.

ValueError: The feature flag configuration is invalid.

The flags dictionary passed to FeatureManager does not conform to the required schema.

fix

Ensure each flag has an 'enabled' key with a boolean value. Optionally add 'conditions' with appropriate filters.
