Linked cards created from checklist : sync Due Date and Item Due Date

[Israphil]

Hey Guys,

I work a lot with checklist and cards created from checklists.
They are linked this way :

• This is the checklist from which the card were created :
  
• Those are the cords with the corresponding due date marked as done or not;
• The cards done/not done status sync well with the checklist thanks to the functions :

• when the due date is marked as complete in a card, find the first card linked in the attachments, and check item "{triggercardlink}" 

• when the due date is marked as incomplete in a card, find the first card linked in the attachments, and uncheck item "{triggercardlink}" 

I would like now to create a function so that when I change the due date of card, the item due date changes too.
But i can't find a simple way... Do you think of any solution?

There is a slightly ugly solution and it would work best if you have an automation "bot" on your board instead of tied to your account.  

The check/uncheck brings focus to that checklist item and then you can set the date.

The same will work for member

Thank you for your answer!
This works but it sets the time as of today. While I want to set the due date checklist the same the due date card, which can be at another date.
It's ugly, but i was inspired by your post to creat this : it solves my issue

I'm using a created custom field where the new due date is stored, then I inject it in the function.

Yeah, sorry my bad.  My example should have shown what you had done.  At least it was enough to get you there

I tried to replicate what you did here, but was not successful.

It appears that you are using a text-type custom field but the "set the item due date on the date in custom field" option would only let me use date-type custom fields.  And since the initial "set custom field" only allows you set text-type fields (not date-type), I can't use it at the last step.

Is your automation still working? What happens if you try to recreate the same automation from scratch?

Perhaps Trello has modified/updated the automation UI since then, and no longer allows test-type custom fields to be used to set the checklist item due date.

Hi @Joon Shin 

Try this:

when a due date is set on a card, find the first card linked in the attachments, set custom field "Date" to "{triggercardduedate}", uncheck item "{triggercardlink}", and set the item due on the date in custom field "Date"
