Interlude.Result.GetBool
In Depth¶
Result.GetBool(result, key, fallback: false)
A field's answer as true or false.
Reads a tick box or a switch directly, and also makes sense of the text and numbers a loaded form might carry — "true", "yes", "1" are true; "false", "no", "0" are false. Anything it cannot make sense of gives the fallback.
This is what gates the rest of a graph, so choose the fallback as the safe answer: the value you would want if the field turned out not to be there at all.
The inputs are:
result(object) — The values dictionary or the form output of Form.Show.key(string) — The field to read.fallback(boolean, defaults tofalse) — Returned when the field is missing.
Returns value — The answer as a boolean.

About the Result nodes¶
Reading a form's answers.
Every node here accepts either the values dictionary or the form output of Form.Show, so it does not matter which one is to hand. They exist so a graph can say what it expects — a number, a date, a colour — rather than pulling an object out of a dictionary and hoping. Each one takes a fallback used when the field is missing or empty, which is what keeps a downstream node from receiving a null it was not expecting.
