CITGuru commented 5 years ago

I guess its already supported. You can call a method to generate choices. So what are you trying to say?

bmwant commented 5 years ago

@CITGuru yes, you can call a function, but there is no ability to make choices dynamic based on previous answers. I want to limit (or extend) options based on previously provided answers to make workflow more flexible.

> how many choices you want to have in the next question? [1, 5]
> function receives previous answers and returns range(answers['size'])

Is there an ability to produce such a behaviour with current code?

bmwant commented 5 years ago

@CITGuru please let me know whether this change is feasible for current repo. I need to base another library on this code, so probably will need to use my own fork if this change will not go into any release. Any feedback is appreciated too.

CITGuru commented 5 years ago

Okay, this might go into dev release for the main time before its pushed to pypi. I'll work on it.

Any updates on this? I am looking for this exact functionality. Also, thank you for this @CITGuru :)
