How to set custom field date to one week before due date

[Kelly Enright]

Hello! I'm trying to figure out how to set custom field date to one week before the due date, but can't figure out how to do this

[Alexey Matveev [cPrime]]

Hello,

You would need an add-on.

For example, you could use the Power Scripts add-on:

You could write a post function with a code like this:

#{your custom field name} = dueData - "1w"

How do I integrate this with Trello, though? I don't see power scripts as a power up?

[Alexey Matveev [cPrime]]

Ah, it is Trello. Sorry I did not notice. My answer is not valid for Trello.

@Kelly Enright this is something you'd need to use the API for, unless you're already a Butler user you can't create an account right now, but this is what it would look like in Trellinator:

 am a butler user! Is trellinator a separate power up as well?

[Iain Dooley]

@Kelly Enright if you already have a butler account, you should be able to use these instructions to set custom field values based on an offset from the due date:

Trellinator is a Google Apps Script library for automating Trello, so it's not a power up. It's more similar to what Butler Bot used to be like before they turned it into a power up. I wrote it to replace Butler Bot for my clients because Butler, while magical and amazing, wasn't suitable as a consulting tool for delivering business systems for my clients.

It's an approved integration on Trello's website though, similar to Zapier:

Here's an example of an issue someone had recently that I helped them work out with Trellinator:
