Doc'd Meta inheritance from abstract parents.
@@ -964,6 +964,33 @@ abstract base class. For example, including ``db_table`` would mean that all
the child classes (the ones that don't specify their own :ref:`Meta <meta-options>`) would use
the same database table, which is almost certainly not what you want.
+Due to the way Python inheritance works, if a child class inherits from
+multiple abstract base classes, only the :ref:`Meta <meta-options>` options
+from the first listed class will be inherited by default. To inherit :ref:`Meta
+<meta-options>` options from multiple abstract base classes, you must
+explicitly declare the :ref:`Meta <meta-options>` inheritance. For example::
+
+ from django.db import models
+
+ class CommonInfo(models.Model):
+ name = models.CharField(max_length=100)
+ age = models.PositiveIntegerField()
+
+ class Meta:
+ abstract = True
+ ordering = ['name']
+
+ class Unmanaged(models.Model):
+ class Meta:
+ abstract = True
+ managed = False
+
+ class Student(CommonInfo, Unmanaged):
+ home_group = models.CharField(max_length=5)
+
+ class Meta(CommonInfo.Meta, Unmanaged.Meta):
+ pass

Be careful with ``related_name`` and ``related_query_name``
