While saving serializer I am getting *DoesNotExist* , *MultipleObjectsReturned* . However objects are being saved in DB but signals such as post_save does not work. Custom Signal also does not work.
Here is detailed error: 1 ['DoesNotExist', 'MultipleObjectsReturned', '__class__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getstate__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__setstate__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', '_check_column_name_clashes', '_check_constraints', '_check_field_name_clashes', '_check_fields', '_check_id_field', '_check_index_together', '_check_indexes', '_check_local_fields', '_check_long_column_names', '_check_m2m_through_same_relationship', '_check_managers', '_check_model', '_check_model_name_db_lookup_clashes', '_check_ordering', '_check_property_name_related_field_accessor_clashes', '_check_single_primary_key', '_check_swappable', '_check_unique_together', '_do_insert', '_do_update', '_get_FIELD_display', '_get_next_or_previous_by_FIELD', '_get_next_or_previous_in_order', '_get_pk_val', '_get_unique_checks', '_meta', '_perform_date_checks', '_perform_unique_checks', '_save_parents', '_save_table', '_set_pk_val', '_state', 'car_category', 'car_id', 'car_model', 'car_owner', 'car_owner_id', 'car_registration_no', 'carimageverification', 'carverification', 'chassis_number', 'check', 'clean', 'clean_fields', 'color', 'date_error_message', 'delete', 'engine_number', 'from_db', 'fuel_type', 'full_clean', 'get_car_category_display', 'get_deferred_fields', 'get_fuel_type_display', 'get_manufacturer_display', 'get_owner_serial_number_display', 'get_ownership_type_display', 'km_ran', 'manufacturer', 'objects', 'owner_serial_number', 'ownership_type', 'pk', 'prepare_database_save', 'rc_back_image', 'rc_front_image', 'refresh_from_db', 'save', 'save_base', 'serializable_value', 'unique_error_message', 'validate_unique', 'verified'] 1 ['DoesNotExist', 'MultipleObjectsReturned', '__class__', '__delattr__', '__dict__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getstate__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__le__', '__lt__', '__module__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__setstate__', '__sizeof__', '__str__', '__subclasshook__', '__weakref__', '_check_column_name_clashes', '_check_constraints', '_check_field_name_clashes', '_check_fields', '_check_id_field', '_check_index_together', '_check_indexes', '_check_local_fields', '_check_long_column_names', '_check_m2m_through_same_relationship', '_check_managers', '_check_model', '_check_model_name_db_lookup_clashes', '_check_ordering', '_check_property_name_related_field_accessor_clashes', '_check_single_primary_key', '_check_swappable', '_check_unique_together', '_do_insert', '_do_update', '_get_FIELD_display', '_get_next_or_previous_by_FIELD', '_get_next_or_previous_in_order', '_get_pk_val', '_get_unique_checks', '_meta', '_perform_date_checks', '_perform_unique_checks', '_save_parents', '_save_table', '_set_pk_val', '_state', 'car_category', 'car_id', 'car_model', 'car_owner', 'car_owner_id', 'car_registration_no', 'carimageverification', 'carverification', 'chassis_number', 'check', 'clean', 'clean_fields', 'color', 'date_error_message', 'delete', 'engine_number', 'from_db', 'fuel_type', 'full_clean', 'get_car_category_display', 'get_deferred_fields', 'get_fuel_type_display', 'get_manufacturer_display', 'get_owner_serial_number_display', 'get_ownership_type_display', 'km_ran', 'manufacturer', 'objects', 'owner_serial_number', 'ownership_type', 'pk', 'prepare_database_save', 'rc_back_image', 'rc_front_image', 'refresh_from_db', 'save', 'save_base', 'serializable_value', 'unique_error_message', 'validate_unique', 'verified'] Here is the code and error <https://dpaste.org/jBtr#>, better formatted.
