Create random default (initial value) in formfields, save initial value and use it in a function

[Monique Meyer]

Hey all,

i want to set a default value (initial value) in formfields that is randomly drawn according to a special probability function. [with a certain probability (p) it is a constant and with a probability (1-p) it is randomly drawn from a normal distribution in the interval (a,b)].

I want to save the default value (initial value) to use it in my statistical analysis later on. I addition, want to program an audit rule that depends on the initial value. Therefore, I have to use the initial value in a function later on.

I read in the otree documentation [About using random()] that I cannot programm a random constant. Instead I have to programm a function. Now, I am totally confused because I really cannot figure out how to solve my problem!

Hopefully, somebody can help me to resolve my confusion. Many thanks!

Best,

Monique

This is what I tried so far. I would call I a nice try...

Try this:

class Subsession(BaseSubsession):

    pass

def creating_session(subsession: Subsession):

    import random

    for player in subsession.get_players():

        r = random.randint(1, 10)

        player.default = r

        player.item_1 = r

class Group(BaseGroup):

    pass

class Player(BasePlayer):

    default = models.FloatField()

    item_1 = models.FloatField()
