mongoz's Issues

With setting the indexes auto generate flag is true

Hello,

I have a Model as:

indexes = [
    Index(keys=[("year", Order.DESCENDING), ("genre", IndexType.HASHED)]),
]


class AnotherMovie(Document):
    name: str = mongoz.String()
    email: str = mongoz.Email(index=True, unique=True)
    year: int = mongoz.Integer()
    uuid: Optional[ObjectId] = mongoz.ObjectId(null=True)

    class Meta:
        registry = client
        indexes = indexes
        database = "test_db"
        autogenerate_index = True

When I create a duplicate record in this model, it allows me to do so, unless I use the await AnotherMovie.create_indexes() method.

And if any model does not have indexes, calling the await AnotherMovie.create_indexes() method returns an error as well.

Thank you.

Embedded Document can't store the ObjectId.

Hello,

I have the two relation i.e. Employee and Supervisors.
Employee document has the the Supervisor as the embedded document

class Employee(Document):
    full_name: str = mongoz.String
    employee_code: str = mongoz.String
    date_of_joining: datetime.datetime = mongoz.DateTime(null=True)
    e_mail: str = mongoz.String(null=True)
    mobile_no: str = mongoz.String(null=True)
    supervisors: List[EmployeeSupervisor] = mongoz.Array(EmployeeSupervisor)


class EmployeeSupervisor(EmbeddedDocument):
    supervisor: ObjectId = mongoz.ObjectId  # Object id of employee document.
    effective_from: datetime.datetime = mongoz.DateTime
    effective_to: datetime.datetime = mongoz.DateTime

Error as:

If you got this error by calling handler(<some type>) within `__get_pydantic_core_schema__` then you likely need to call `handler.generate_schema(<some type>)` since we do not call `__get_pydantic_core_schema__` on `<some type>` otherwise to avoid infinite recursion.

How can we achieve this?
Thank you.

Getting issue while storing the decimal value in the document.

Hello,

I am trying to store the decimal value in by embedded document:

Class Achived(Document):
    score_from: float = mongoz.Decimal
    score_to: float = mongoz.Decimal(max_digits=5, decimal_places=3)
    amount: float = mongoz.Decimal(
        max_digits=5, decimal_places=3)

When I try to store the decimal value it raise the exception as:
InvalidDocument("cannot encode object: Decimal('0.60'), of type: <class 'decimal.Decimal'>")
.
As I passing the string or float value for it to store in document.

Getting the issue while using the Abstract class.

Hello,
I have a models as:

class BaseDocument(mongoz.Document):
    """
    The base document for all documents using the `registry` registry.
    """
    objects: ClassVar[CustomManger] = CustomManger()

    class Meta:
        """
            It contains the Meta information related the database for \
                each model level.
        """
        abstract = True
        registry = settings.client
        database = settings.db

class Employee(BaseDocument):
    month_period: int = mongoz.Integer(null=True)
    full_name: str = mongoz.String()
    employee_code: str = mongoz.String()
    date_of_joining: datetime.datetime = mongoz.DateTime(null=True)
    e_mail: str = mongoz.String(null=True)
    mobile_no: str = mongoz.String(null=True)

When I am trying to query into db, Its using the default manager i.e. "Manager" object, instead of "CustomManager".

If I again initialize the "objects" in the Employee Document and try to query as:

Employee.objects.create(full_name='Emp_Name_1326', employee_code='01326')

Then, it returns the API response as:

}

Can you help me for this?
Is somthing wrong here?
