+# ThrillWiki Django Project - Pylint Configuration
+# =============================================================================
+#
+# Purpose: Django-aware Pylint configuration that suppresses false positives
+#          while maintaining code quality standards.
+#
+# Alignment:
+#   - Line length: 120 characters (matches Black and Ruff in pyproject.toml)
+#   - Django version: 5.2.8
+#
+# Key Features:
+#   - Suppresses false positives for Django ORM patterns (.objects, _meta, .DoesNotExist)
+#   - Whitelists Django management command styling (self.style.SUCCESS, ERROR, etc.)
+#   - Accommodates Django REST Framework patterns
+#   - Allows django-fsm state machine patterns
+#
+# Maintenance:
+#   - Review when upgrading Django or adding new dynamic attribute patterns
+#   - Keep line-length aligned with Black/Ruff settings in pyproject.toml
+#

+    # C0114: missing-module-docstring
+    # Django apps often don't need module docstrings; the app's purpose is
+    # typically documented in apps.py or README
+    C0114,
+
+    # C0115: missing-class-docstring
+    # Django models, forms, and serializers are often self-documenting through
+    # their field definitions and Meta classes
+    C0115,
+
+    # C0116: missing-function-docstring
+    # Allow simple functions and methods without docstrings; Django views and
+    # model methods are often self-explanatory
+    C0116,
+
+    # C0103: invalid-name
+    # Django uses non-PEP8 names by convention (e.g., 'pk', 'id', 'qs')

+
+    # C0415: import-outside-toplevel
+    # Django often requires lazy imports to avoid circular dependencies,
+    # especially in models.py and signals
+    C0415,
+
+    # W0212: protected-access
+    # Django extensively uses _meta for model introspection; this is documented
+    # and supported API: https://docs.djangoproject.com/en/5.2/ref/models/meta/
+    W0212,
+
+    # W0613: unused-argument
+    # Django views, signals, and receivers often have unused parameters that
+    # are required by the framework's signature (e.g., request, sender, **kwargs)
+    W0613,
+
+    # R0903: too-few-public-methods
+    # Django models, forms, and serializers can be simple data containers
+    # with few or no methods beyond __str__
+    R0903,
+
+    # R0801: duplicate-code
+    # Django patterns naturally duplicate across apps (e.g., CRUD views,
+    # model patterns); this is intentional for consistency
+    R0801,
+
+    # E1101: no-member
+    # Main source of false positives for Django's dynamic attributes:
+    # - Model.objects (Manager)
+    # - Model.DoesNotExist / MultipleObjectsReturned (exceptions)
+    # - self.style.SUCCESS/ERROR (management commands)
+    # - model._meta (Options)

+# Whitelist Django's dynamically generated attributes
+# =============================================================================
+[TYPECHECK]
+# Django generates many attributes dynamically that Pylint cannot detect
+# statically. This list covers common patterns:
+#
+# - objects.*    : Django ORM Manager methods (all, filter, get, create, etc.)
+# - DoesNotExist : Exception raised when Model.objects.get() finds nothing
+# - MultipleObjectsReturned : Exception when get() finds multiple objects
+# - _meta.*      : Django model metadata API (fields, app_label, model_name)
+# - style.*      : Django management command styling (SUCCESS, ERROR, WARNING, NOTICE)
+# - id, pk       : Django auto-generated primary key fields
+# - REQUEST      : Django request object attributes
+# - aq_*         : Acquisition attributes (Zope/Plone compatibility)
+# - acl_users    : Zope/Plone user folder
