Step 1: 🔎 Searching

I found the following snippets in your repository. I will now analyze these snippets and come up with a plan.

Step 2: ⌨️ Coding

[X] Modify modelcluster/queryset.py ✓ https://github.com/captkirk96/same_django/commit/0006591a45ee76956bf6978f4cc54185ba54b9b7 Edit
Modify modelcluster/queryset.py with contents:
• Review the existing iterable classes (`ModelIterable`, `DictIterable`, `ValuesListIterable`, `FlatValuesListIterable`) to ensure they return values in the expected format. If necessary, adjust the `__iter__` methods of these classes to more closely mimic Django's queryset behavior. This might involve refining how field values are extracted and formatted.
• Enhance the `values()` method implementation starting from line 492. Ensure that it supports chaining with other queryset modifiers such as `filter()`, `exclude()`, and `order_by()`. This might involve adjusting how the `clone` of the `FakeQuerySet` is created and ensuring that the `dict_fields` attribute is correctly handled to reflect the fields specified in the `values()` call.
• Verify and possibly adjust the `values_list()` method implementation starting from line 501 to ensure it works seamlessly with the `values()` method and supports the `flat` parameter correctly. This includes raising a `TypeError` if `flat=True` is specified with more than one field, as per Django's behavior.
• Add comprehensive comments to the `values()` and `values_list()` methods explaining the logic and how it mimics Django's queryset behavior. This will help future maintainers understand the purpose and functionality of these methods.
• Ensure that all modifications maintain the lazy evaluation characteristic of the `FakeQuerySet`, meaning that the actual data processing should not occur until necessary (e.g., when iterating over the queryset).
