How to use mypy with django ninja ModelSchema?

[VityasZV]

ModelSchema Definition:

class ServiceSchemaIn(ModelSchema):
    product_id: int

    _validate_id_field = validator("product_id", allow_reuse=True)(validate_int_is_bigger_than_zero)

    class Config:
        model = Service
        model_exclude = ["product", "created", "updated", "status"]`

Default mypy run can’t detect attributes of django model from schema:

src/service_manager_app/service/logics.py:129: error: "ServiceSchemaIn" has no attribute "id"
src/service_manager_app/service/logics.py:131: error: "ServiceSchemaIn" has no attribute "id"
src/service_manager_app/service/logics.py:133: error: "ServiceSchemaIn" has no attribute "id"
src/service_manager_app/service/logics.py:134: error: "ServiceSchemaIn" has no attribute "period"
src/service_manager_app/service/logics.py:135: error: "ServiceSchemaIn" has no attribute "id"
src/service_manager_app/service/logics.py:136: error: "ServiceSchemaIn" has no attribute "period"
src/service_manager_app/service/logics.py:140: error: "ServiceSchemaIn" has no attribute "code"
src/service_manager_app/service/logics.py:142: error: "ServiceSchemaIn" has no attribute "adm_name"
src/service_manager_app/service/logics.py:144: error: "ServiceSchemaIn" has no attribute "attr_name"
src/service_manager_app/service/logics.py:145: error: "ServiceSchemaIn" has no attribute "is_single"
src/service_manager_app/service/logics.py:145: error: "ServiceSchemaIn" has no attribute "one_time"
src/service_manager_app/service/logics.py:145: error: "ServiceSchemaIn" has no attribute "xpath"
src/service_manager_app/service/logics.py:145: error: "ServiceSchemaIn" has no attribute "action"
src/service_manager_app/service/logics.py:150: error: "ServiceSchemaIn" has no attribute "code"

Just a fragment of Django model definition:

class Service(GenericModel):
    objects = models.Manager()

    action = models.BooleanField(blank=True, null=True)
    adm_name = models.CharField(max_length=255, blank=True, null=True)
    attr_name = models.CharField(max_length=2000, blank=True, null=True)
    code = models.CharField(unique=True, max_length=255, blank=True, null=True)
    is_corporate = models.BooleanField(blank=True, null=True)

Sooo, I will be extremely grateful for any help or advice about mypy + django ninja !

well there is no way to make mypy and ModelSchema friends , because this class schema is created at runtime

so it's either you ignore it or define each attribute of the schema manually:

class ServiceSchemaIn(Schema): # Not ModelSchema
    product_id: int
    created: datetime
    ...
