Build questions, answer options or default answers upon previous answers

Rationale / Begründung

Rendering some questionnaires in RDMO requires to make the platform interactive, where the presentation of questions and possibly some new variable values build upon already answered questions.
For example: A variable V3 is pre-calculated on the basis of variables V1 and V2; the result is shown to the user, who can agree or not with the value; if yes, the value for V3 stays; if not, he/she will enter a new value and possibly add some justification for the change.

Users, Managers

Minimal functionality

It should be possible to add short code snippets, in Django or JavaScript, in the question texts or help texts, which both write values into the memory and show conditioned text on the user interface.

Nice-to-have functionality

Build also answer optionsets based on existing variable values

Sketch of the use case considered (the variable "integrity level" is calculated based on the two variables "complexity" and "criticality").

Hint to use case implementation in RDMO.

No implementation files or tests are named. Start by tracing how questionnaire question and help text are rendered and how variable answers are stored, then compare that flow with the linked use cases. Done should support snippets that write values and conditionally show text, with answer optionsets based on existing values as an optional extension.
