Hello Jacob,

Thanks for reaching out to the Skuid community.

You absolutely can create child records using a custom mass action snippet!

An example of creating lookup references can be seen on this question from a couple days ago, but the logic would be very similar (if not the same) for a Master-Detail records:

Create records in a table based on selected records in another table

If you need any help adapting that example for your use, please feel free to reply to this thread and we’ll see what we can do for you.

Cool, I will take a look!

Hi Jacob, here is the XML for a sample page that lets you Mass-Create Tasks for selected Contacts, with the added benefit of letting you prepopulate certain fields via the use of a “Prototype” Task Model to which you can add any fields you’d like, and the JS Snippet will pick up on the field values your users would like to prepopulate and add them to the new Tasks:

Gist: MassCreateActivitiesForContacts

Here is a screenshot of what this looks like:

This is GRRRREAT!

Now I have to figure out a Subquery to filter contacts by ContactTag!
