👍 This will work.

Good idea with naming it unknown and showing it to the user.

[gtanzillo]

This seems like it should address the case where a container image is not connected a project. Were you able to test this out to make sure the the "unknown project" can be displayed properly on the report?

For the future reference, the traceback was:

@gtanzillo instead of creating something custom for this entry can the reporting system cope with nils? Maybe transforming those in special vaules e.g. "Missing Field".

@gtanzillo Yes. The screenshot above is the result of running the report after setting the project_id to nil on a pod(container_group)

Thanks @zeari I forgot to look at the screenshot! 👍

I think the reporting system will handle a grouping of nil without blowing up. But, I think its better that there is an actual name on the grouping because the reporting system will just show the nil.

@gtanzillo if the column is named "Project" (as in this case) and the cell has a value of "Missing Field" (when nil) then it seems descriptive enough.

[isimluk]

I think there might be some confusion going on. The project AR does never get down to the report formatter. The project AR never leaves the ChargebackContainerProject class.
