Common errors

error Module 'pylint_flask_sqlalchemy' not found ↓

cause Plugin not installed or incorrect import path.

fix

Run pip install pylint-flask-sqlalchemy and ensure the package is in your Python path.

error E: 10, 0: Instance of 'User' has no 'name' member (no-member) ↓

cause Pylint not recognizing SQLAlchemy columns.

fix

Load the plugin via .pylintrc or command line: --load-plugins=pylint_flask_sqlalchemy.

error pylint: error: unrecognized arguments: --load-plugins=pylint_flask_sqlalchemy ↓

cause Old pylint version that doesn't support the option or the plugin is not installed.

fix

Upgrade pylint to at least 1.7 or ensure the plugin is installed and accessible.

Warnings

deprecated Support for Python 3.5 only; Python 3.6+ may require adjustments. The library is no longer actively maintained. ↓

fix Consider migrating to pylint-sqlalchemy or directly configuring pylint's generated-members.

gotcha The plugin may not work with newer versions of pylint (2.x+). The last release (0.2.0) was published in 2018 and may have compatibility issues. ↓

fix Check compatibility with your pylint version; consider using pylint-extension or contrib plugins.

gotcha The plugin only handles Flask-SQLAlchemy's `db.Model` and common patterns; custom attributes or dynamic models may still trigger false positives. ↓

fix Use `generated-members` in pylintrc or ignore specific warnings manually.
