Check off an item from a checklist that matches the link on another card

[Pat]

Hello,
I've been thinking about automating Trello for a while now and considering the answers provided on this forum, it would be a shame not to take advantage of your knowledge!

The idea is simple, I have a first main card that gathers different work checklists. The items of these checklists are composed of the link of the cards of these jobs. This gives this for example:

I would like that when the work card, is moved (automatically or not) to the "Completed" list, the main card item is checked.

Is this possible and if so via which command?
I put the link of the card thinking that automation would be easier than (badly) retyped titles by hand.

Hopefully my English is good!

Thank you :)

Hi Pat! How are you? Welcome to the community!

I did some tests here and I found that this automation is possible!

Here is the butler rule I used:

when a card is moved into list "DONE", find a card titled "List", and check item "{triggercardlink}" in checklist "All Tasks"

I created a video to illustrate and make it easier to understand: https://share.getcloudapp.com/E0uRo0P8

You can check this documentation with detailed information about butler variables and also you can click here to learn more about finding and looking up cards.

Hope that is what you are looking for. Please let me know if you have any questions about it.

Hello Luciana,
Thanks for your answer and for the butler rule you used, but it doesn't work now and for reason I can't access the video. CloudApp says that the link is no longer accessible.
Is it me who is not doing the right thing to access it?

But this rule from documentation work !

"when a card is added to list "Doing" by me, find a card titled "Rollup", and add item "{triggercardlink}" to checklist "Doing""

Ok, the butler rule works fine but only with new cards added. The old ones are not taken into account by the new automation.
So it's better to create the rules first and then get to work!
Thanks for your help :)

Hi Pat! You're very welcome!

Sorry that the video link expired and you weren't able to watch it. That is something related to the Cloudapp :(

But awesome that it worked and you were able to create the rule! Yes, you are right. Better create the rule first before working with the cards.

Here is a step by step and a screenshot just in case you need it for reference in the future:

Copy the link to that card you want to add as an Item on your checklist by:

1 - clicking on the share button of the card

2- copy the link 

3 - paste it as an item of your checklist.

To create a rule go to Automation > Rules > Create a Rule button

Click on Add a Trigger

Choose “when a card is moved into list (select the name of the list where you’ll move your cards when is completed) - my example the list is called DONE

Click on the plus button to add this trigger

Go to Cascade option

Choose “find a card titled” (type the exactly name of your card where your checklist is located) - my example the card name is List

Click on the plus button to add the action

Go to Checklist option

Choose “check item {triggercardlink} in the checklist (the checklist name you created) - mine was called All Tasks

Click on the plus button to add the action

{triggercardlink} is the variable you need to use as is.

Click on the Save button
