Hello,
i have 2 tables deckarations and actions
I want to let the customer provide a list of actions (in grid view) when creating a new declaration(in the form itself) and so the actions will be linked to the declaration.
the problem is i can’t find a way to create this link as i do not have the rowid of the declaration before it’s submitted.
Is there a way to do that?
thx

What I would do is use a custom form.

This is a simple concept app (copyable), that demonstrates the following techniques: Building custom forms for adding and editing list items (as an alternative to the native forms provided by Glide) Preventing duplicate new entries using [User Specific Columns](https://docs.glideapps.com/all/reference/data-editor/user-specific-columns) and [Relations](https://docs.glideapps.com/all/reference/data-editor/computed-columns/relation-column) Enforcing mandatory input items The use of visibility conditions and user specific booleans to control user flow There is nothing particula…
On entry to opening the form screen, set a " Unique Identifier" value to a column. That can become the link between your “declarations” and “actions”.
When you add a row for the declaration, make sure you get the “Unique Identifier” value in as a column. Same thing for actions. Then you can have a relation between those 2.
