Create and Sort "Subject" number as in zTree

[X. Zhou]

Dear all,

I am finding a way to create a subject_number variable similar to the Subjects variable in zTree.

The main reason is to match computer station number with oTree participant number and also create variables based on their subject number flexibly.

Please note that the snippet :

def creating_session(self):
    labels = [1, 2, 3 , ...]
    for player, label in zip(self.get_players(), labels):
        player.participant.label = label

does not work because if work station 2 is empty, then label 2 wil be assigned to station 3.

It would also be nice to access the "subject number" variable, curretly, in the data, there is only P1, P2, etc. I am wondering how to create the subject variable based on that.

Thanks!

Best,

Zhou

Just add ?participant_label=PC_number (e.g., ?participant_label=01, ?participant_label=02, etc.) to the URLs when opening the oTree URL in the browser on the participants’ PCs.

See, for instance, https://groups.google.com/g/otree/c/FIDiiE-H3Tc/m/f1Nm7180AQAJ.
