feat: expose IoC-Sensor relationship in API responses

[aashnaachaudhary10]

Description

This PR addresses the requirement to expose the relationship between Indicators of Compromise (IoCs) and their reporting Sensors in the API responses. By updating the IOCSerializer, we now include a sensors field that lists the addresses of all sensors associated with a specific IoC using a SlugRelatedField.

This branch has been re-created based on the latest develop branch to ensure a clean commit history and compatibility with the current project structure.

• Closes Add new IoC fields to API #781

Type of Change

• New feature (non-breaking change which adds functionality)

Checklist

• My branch is based on develop
• I have verified the changes manually using the Django shell
• Linter (Ruff) gave 0 errors

Verification Proof (Manual Testing)

I verified the serializer output within the Docker environment (greedybear_uwsgi container):

from api.serializers import IOCSerializer
from greedybear.models import IOC, Sensor

# Test data setup
s, _ = Sensor.objects.get_or_create(address="10.0.0.1")
i, _ = IOC.objects.get_or_create(name="1.2.3.4", type="ip")
i.sensors.add(s)

# Serialization test
data = IOCSerializer(i).data
print(data['sensors'])
# Output: ['10.0.0.1']

Hey @aashnaachaudhary10 ! First of all, the CI should not fail! ;) Please fix that.

Hi @regulartim I've updated the IOCSerializer to include the sensors field as requested. However, I see one CI test failing. It seems like it might be related to the expected response schema in the tests. Could you please guide if I should update the test cases as well?

However, I see one CI test failing.

Hi! I haven't gone through code changes , but looking at your CI error, it's clear the failure is coming from the linter rather than the functional tests.

It looks like the code in api/serializers.py just needs to be reformatted to match the project's style. You can fix this locally and prevent it from happening again by setting up the pre-commit hooks as mentioned in the docs

Hi @drona-gyawali , thank you for pointing that out! I've now configured pre-commit with Ruff as per the documentation to ensure the formatting matches the project's style. I'm also updating the test cases to fix the backend test failure. Really appreciate the help!

Hey @aashnaachaudhary10 ! You included the filed in the serializer, but this does not automatically expose it in the API responses, right? Did you test the API response? Did it contain the relation? Maybe add a test for that! Also, it seems like you included a lot of unrelated changes in this PR.

Hi @regulartim , thank you for the feedback!

I have just removed the unrelated files (.vscode/settings.json and package-lock.json) that were accidentally included.

I did verify the response manually in the Docker environment (as shown in the screenshot in my description), and the sensors field was correctly populated with the sensor addresses.

Aut I understand the importance of an automated test for this. I will add a test case to verify this relationship in the API response shortly and update the PR.

Thanks for your patience!

Hey @aashnaachaudhary10 ! Now you completely removed the package-lock.json. But it is needed for building the frontend. Also, I still don't see how your changes will expose the relationship in the API.
