Description

When url is configured in the [tool.datamodel-codegen] section of pyproject.toml, the --input CLI flag is silently ignored, and the tool fetches from the configured URL instead of reading the specified local file.

Reproduction

Config (pyproject.toml):

[tool.datamodel-codegen]
url = "https://example.com/openapi.json"
input_file_type = "openapi"
output = "src/my_package/_models.py"

Command:

datamodel-codegen --input local-openapi.json

Expected behavior: The tool should use local-openapi.json as input, since the CLI flag was explicitly provided. CLI arguments should take precedence over config file settings.

Actual behavior: The tool ignores --input and fetches from the url defined in pyproject.toml.
