|
|
this is to reconcile vars(cls) with cls.__annotations__.
|
|
Example::
|
|
>>> a = ['__tablename__', 'id', 'x', 'created_at']
|
>>> b = ['id', 'name', 'data', 'y', 'created_at']
|
>>> merge_lists_w_ordering(a, b)
|
['__tablename__', 'id', 'name', 'data', 'y', 'x', 'created_at']
|
|
This is not necessarily the ordering that things had on the class,
|
in this case the class is::
|
|
class User(Base):
|
__tablename__ = "users"
|
|
id: Mapped[int] = mapped_column(primary_key=True)
|
name: Mapped[str]
|
data: Mapped[Optional[str]]
|
x = Column(Integer)
|
y: Mapped[int]
|
created_at: Mapped[datetime.datetime] = mapped_column()
|
|
But things are *mostly* ordered.
|
|
The algorithm could also be done by creating a partial ordering for
|
all items in both lists and then using topological_sort(), but that
|
is too much overhead.
|
|

a callable that returns a new object to be placed in the registry
|

a callable that will return a key to store/retrieve an object.
