Interlude.Form.Check
In Depth¶
Form.Check(form)
Reports the problems Interlude can see in a form without showing it: conditions that name a field that does not exist, duplicate keys, and computed values that depend on each other in a loop.
The inputs are:
form(FormDefinition) — The form to check.
The outputs are:
isValid— True when nothing was found.messages— What was found, if anything.
Search terms: validate, check, lint, problems, warnings, debug.
About the Form nodes¶
Showing a form and getting the answers back.
A note on re-execution, because it surprises everyone once: Dynamo re-runs a graph whenever anything upstream changes, and a node that shows a dialog will show it again. Interlude does not pretend otherwise — it gives you the tools to control it. The trigger port skips the dialog and returns the last answers when it is false, so a form can be gated behind a button or a boolean. A form already on screen is never opened twice: a second execution waits for the first window and returns its result rather than stacking dialogs. And Manual run mode remains the right setting for any graph built around a form.
