How to Use OAS to Pydantic

The OAS specifications can be used to generate the Pydantic models that validate updates to the database.

Running the Script

• Basic usage:

  python generate_pydantic_models.py path_to_your_oas.yaml generated_models.py
  

• With verbose output:

  python generate_pydantic_models.py path_to_your_oas.yaml generated_models.py --verbose
  

Example Usage

python generate_pydantic_models.py models/agencies.yaml pydantic/agencies.py --verbose

Output:

Caveats

Polymorphism

The converter doesn't handle polymorphic properties yet. There's been a bit of effort put into making sure it can follow 'allOf' references, but I haven't done any investigation into how it handles 'oneOf' refs. For example, SourceDetails on complaints.

External File References

The generator only looks at one file at a time. It will not follow references to other files. The generator currently just assumes that those references exist and are valid.
