Describe the bug

If you pass the relationship variable with incorrect parameters into a CSV file for import, and set continue_on_error: 0, then the record will be saved as valid but without the relationship.

Steps to reproduce the bug

async def test_import_csv_continue_on_error_false(client: AsyncClient) -> None:
    class AddressContinueeOnErrorFalseAdmin(ModelView, model=Address):
        can_import = True
        column_import_list = [Address.id, Address.user]

    local_app = Starlette()
    local_admin = Admin(app=local_app, engine=engine)
    local_admin.add_view(AddressContinueeOnErrorFalseAdmin)

    transport = ASGITransport(app=local_app)
    async with AsyncClient(
        transport=transport,
        base_url="http://continue_on_error",
    ) as local_client:
        
        response = await local_client.post(
            "/admin/address/import",
            data={"continue_on_error": "no"},
            files={
                "csvfile": (
                    "address.csv",
                    b"id,user\r\n1,adg34gfb13\r\n",
                    "text/csv",
                )
            },
        )
        assert 'Import aborted on invalid row 2. No rows were imported' in response.text

Expected behavior

Stop import and output error.

Actual behavior

Import continues as if nothing happened.

Debugging material

Studying the code led me to these two function calls. It is assumed that the error should have been caught in one of them:

sqladmin/sqladmin/_import.py

Line 443 in 64372dd

merged_import_data, row_errors, row_data = validate_import_row(

sqladmin/sqladmin/_import.py

Line 451 in 64372dd

foreign_key_errors = await validate_foreign_key_values(

Here is what comes when you run the test from the example:

print(f'{row = }')
processed += 1
merged_import_data, row_errors, row_data = validate_import_row(
    row,
    model_view._import_prop_names,
    model_view.model,
    form_class,
    denormalize_wtform_data,
)
print(f'{merged_import_data = }')

foreign_key_errors = await validate_foreign_key_values(
    model_view=model_view,
    row_data=merged_import_data,
    fk_error_cache=fk_error_cache,
)
for field_name, field_errors in foreign_key_errors.items():
    row_errors.setdefault(field_name, []).extend(field_errors)

print(f'{row_errors = }')

row = MultiDict([('id', '1'), ('user', 'adg34gfb13')])
merged_import_data = {'id': 1, 'user': None}
row_errors = {}

Environment

sqladmin 0.30.0
