Describe the bug
The .py file generated from the attached openapi spec contains repeated import statements and some class definitions are redefined later in the .py file.
e.g.
Its possible that the openap spec file is not well formed, that may be the cause of this issue. I don't have control over the openapi file itself, I can't change it.
To Reproduce
Run the command line shown below
Example schema:
customscity-2.0.1.json
Used commandline:
$ datamodel-codegen --input customscity-2.0.1.json \
--output-model-type pydantic_v2.BaseModel --target-pydantic-version 2.12 \
--snake-case-field --openapi-scopes schemas parameters paths \
--allow-extra-fields --use-standard-collections --use-union-operator \
--force-optional --allow-population-by-field-name \
--target-python-version=3.14 --collapse-root-models \
--use-schema-description --capitalise-enum-members \
--enable-version-header --use-annotated \
--output-datetime-class datetime \
--formatters ruff-check ruff-format \
> customscity_201_import.pyExpected behavior
I expect all the import statements to be at the top of the generated file, and for none of the class names to be redefined.
Instead I get this output file:
customscity_201_import.py
Version:
- OS: Debian Trixie in devcontainer
- Python version: 3.14
- datamodel-code-generator version: 0.68.1
Additional context
This project is a life saver, thank you very much for building this program.
I can hand edit the generated file to work around this issue, so its not a critical problem.
