bug: importing functions from other modules in repository doens't work consistently

[wvandeun]

Component

Python SDK, infrahubctl

Infrahub SDK version

0.14.0

Current Behavior

When you want to import functions (or classes, variables) from other python modules into python transformations or generators then there is inconsistency on how this can be achieved.

resource	infrahubctl (relative)	infrahubctl (absolute)	Infrahub (relative)	Infrahub (absolute)
transform	❌	❌	✅	❌
generator	❌	✅	✅	❌

Expected Behavior

Ideally we can import functions / classes variables from modules using relative imports when doing this in tranformations and generators, running locally or within Infrahub.

This way common code in transformations and generators can be shared in modules that are located anywhere within the repository.

Steps to Reproduce

• load an instance of Infrahub with the demo schema
• create a BuiltinTag node
• create an external repository
• define the following .infrahub.yml file

---
queries:
  - name: test
    file_path: test.gql

python_transforms:
  - name: configuration
    file_path: transformers/configuration.py
    class_name: Configuration

• create a directory transformers in the root of the repository
• create a file transformers/configurations.py with the following contents

from typing import Any, Dict
from infrahub_sdk.transforms import InfrahubTransform

from .utils import get_value

class Configuration(InfrahubTransform):
    query: str = "test"

    async def transform(self, data: Dict[str, Any]) -> Dict[str, Any]:
        return {
            "utils.get_value": get_value(),
        }

• create a file transformers/utils.py with the following contents

def get_value() -> str:
    return "value"

• create a file test.gql at the root of the repository with the following contents

query test($name: String!) {
  BuiltinTag(name__value: $name) {
    edges {
      node {
	name {
	  value
	}
      }
    }
  }
}

• stage all the newly created files and commit them
• try running the transformation using infrahubctl transform configuration > issue importing the get_value function
• push the changes to a git remote
• import the repository into Infrahub
• run the transformation through the REST API > works
