Mark parent card as complete only when all child cards are under a specific list

[physx]

Hello!

I'm using Butler to copy cards in another list on the same board and link them together. The board has many lists and the parent card has many copies into other lists.

Is there a way to mark parent card as complete only when all the child cards are under a specific list?

Thanks!

@physx This Trellinator command will trigger when a card is moved to list "Completed List" and find the parent card linked in the attachments, then loop through all the attachments on the parent card and check if they are all in the list "Completed List" and if so, will mark the parent card complete:

Thank you, this works! Is there a way to understand and code my own Trellinator commands?

@physx hey there, sorry for the delayed response. You can find out more in-depth how Trellinator works in the documentation:

https://www.theprocedurepeople.com/trellinator-automate-trello/docs/

In particular the "Hello World" tutorial linked from that page gives you a much more complete picture of how to create and deploy Trellinator code including version control and writing command line tests etc.

I am quite familiar with the Butler Power-Up, and I think it is safe to say that there are currently no actions to achieve this with the Butler Power-Up. And if so, it could be very complicated.

You may want to consider using a Power-Up that can track task dependencies, like the Epics by Screenful Power-Up or the Hello Epics Power-Up.

Here is a nice article that explains these Power-Ups a bit.

From what I understood the task is for you, I'd probably recommend the Hello Epics Power-Up to you.
