Pull Request Overview
This PR updates the CLI’s todict utility to use Azure Core’s serialization helpers (is_generated_model and attribute_list) instead of the older as_dict logic, ensuring correct handling of renamed/ formatted SDK model attributes.
- Import
is_generated_modelandattribute_listfromazure.core.serialization - Replace the old
as_dictbranch with a single path usingis_generated_model - Remove legacy typespec
as_dicthandling
Comments suppressed due to low confidence (2)
src/azure-cli-core/azure/cli/core/util.py:654
- Add unit tests for this new
is_generated_modelbranch to cover both swagger and typespec generated models, verifying thatattribute_listcorrectly enumerates renamed/formatted attributes.
if is_generated_model(obj):
src/azure-cli-core/azure/cli/core/util.py:629
- Update the function docstring to mention the support for Azure Core generated models via
is_generated_modelandattribute_list.

We need to check whether the attr exist because we may import SDK model and then do some customization like keyvault certificate L122-127

How did it handle the nested case? When the internal property is also an object？

Description
Previously we added dict transformation for typespec generated SDK models in #30339, we called typespec generated SDK model's
as_dictfunc to get each attribute name and attribute value. But this still causes issues like #31529 reported whenWe can take the
expiredattribute from Keyvault SDK as an example:The
expiresis renamed fromexpin http response and hasunix-timestamptime format. By callingas_dict{'expires': '2027-05-28T16:43:07+00:00'}(from swagger generated SDK model){'exp': 1811522587}(from typespec generated SDK model).The renaming and formatting was not applied to
as_dictand this behavior applies for all typespec generated SDK models.To resolve this breaking change, SDK team added related serialization support in azure-core with Azure/azure-sdk-for-python#41445, Azure/azure-sdk-for-python#41571. They now have two functions to handle both swagger generated SDK and typespec generated SDK:
is_generated_modelto identify auto generated SDK modelsattribute_listto list all attribute names which are after renaminggetattr(obj, attr)for the attribute we get fromattribute_listto get the attribute value which is after formattingThis PR changes the dict formatting for typespec generated SDK models with new
attribute_listfunc. We didn't adoptis_generated_modelbecause we don't want to change swagger generated SDK models' dict formatting to avoid any regressions.Testing Guide
