Hi there,

Hope you are well. I know that lately, I have posted several queries and I would like to apologise for the inconvenience. Being a first time programmer, while programming my experiment, I am still learning. I don't have any colleagues who knows otree or Python that works in my field as well. Hence, I pretty much depend on your wonderful support system. 

The question I have today is mainly two parts. 

1) I have designed a group treatment. However, the payoff for each player is always coming to be zero. The codes are mentioned below. 
from otree.api import *
import numpy as np

cu = Currency


class C(BaseConstants):
    NAME_IN_URL = 'group_esg'
    PLAYERS_PER_GROUP = 2
    NUM_ROUNDS = 1
    ENDOWMENT_PER_PLAYER = 100
    payment_assetA = 110
    payment_assetB = 115
    payment_otherwise = 30


class Subsession(BaseSubsession):
    pass


class Group(BaseGroup):
    get_payoff = models.IntegerField()

class Player(BasePlayer):
    decision1 = models.BooleanField(
        label="Please make a selection between Asset A and Asset B",
        choices=[
            [True, "Asset A"],
            [False, "Asset B"],
        ],
        widget=widgets.RadioSelectHorizontal
    )
    decision2 = models.BooleanField(
        label="Please make a selection between Asset A and Asset B",
        choices=[
            [True, "Asset A"],
            [False, "Asset B"],
        ],
        widget=widgets.RadioSelectHorizontal
    )


# PAGES
class OriginalDecision(Page):
    form_model = "player"
    form_fields = ["decision1"]
    time = models.FloatField()

    @staticmethod
    def vars_for_template(player: Player):
        return dict(
            image_path='esg_wealth/flag2.jpg',
            pdf_path='Environmental report.pdf'
        )

    @staticmethod
    def live_method(player, data):
        player.time = data

class ResultsWaitPage(WaitPage):
    pass

class Revision(Page):
    @staticmethod
    def vars_for_template(player: Player):
        opponent = player.get_others_in_group()[0]
        return dict(
            opponent=opponent,
            same_choice=player.decision1 == opponent.decision1,
            my_decision=player.field_display('decision1'),
            opponent_decision=opponent.field_display('decision1'),
        )

class RevisedDecision(Page):
    form_model = "player"
    form_fields = ["decision2"]
    time = models.FloatField()

    @staticmethod
    def vars_for_template(player: Player):
        return dict(
            image_path='esg_wealth/flag2.jpg',
            pdf_path='Environmental report.pdf'
        )

    @staticmethod
    def live_method(player, data):
        player.time = data



class Results(Page):
    @staticmethod
    def after_all_players_arrive(player: Player):
        pchoice = np.random.random()
        if pchoice <= 0.5:
            Group.get_payoff = 1
        else:
            Group.get_payoff = 0
        if player.decision2 == True:
            player.payoff += C.payment_assetA * Group.get_payoff
        if player.decision2 == False:
            player.payoff += C.payment_assetB * Group.get_payoff
        if Group.get_payoff == 0:
            player.payoff += C.payment_otherwise

page_sequence = [OriginalDecision, ResultsWaitPage, Revision, RevisedDecision, ResultsWaitPage, Results]

2) My problem is with the rounding up of my payoff. So, £11.50 becomes £12.00. I tried my best to figure out a way to stop this but haven't been able to figure out anything yet. I have created a separate app for this. This is the code I am using:
class Payment(Page):
    @staticmethod
    def vars_for_template(player: Player):
        participant = player.participant
        return dict(
            redemption_code=participant.label or participant.code,
            earning = format(float(participant.payoff / 10), '.2f')
        )

Q1: do not write models under Page:
like the code:
# PAGES
class OriginalDecision(Page):
    form_model = "player"
    form_fields = ["decision1"]
    time = models.FloatField()
  
 write the line "time = models.FloatField()" in Player field. 

Q2: write two time vars in Player
In the Player field, now we have a "time" var in Player field. But the time is rewrittern in the RevisedDecision Page. So add "time1" and "time2" to differ. 

Q3: for payoff always = 0 issue, try to add a new page before Results Page. In this new page, add your code for determining payoff here. And in Results Page, just show the number to subjects.

Hi Fanist,

Thank you for your reply. Unfortunately payoff = 0 problem still persists. Another quick question. I have created time1 and time2.In that case, any mention of time in html pages should also be time 1 and time2, is that correct?

Hi Fanist,

So I have been able to solve the problem. I didn't add a new page before Results page. Just did this:
class Results(Page):
    @staticmethod
    def vars_for_template(player: Player):
        pchoice = np.random.random()
        if pchoice <= 0.5:
            Group.get_payoff = 1
        else:
            Group.get_payoff = 0
        if player.decision2 == True:
            player.payoff += C.payment_assetA * Group.get_payoff
        if player.decision2 == False:
            player.payoff += C.payment_assetB * Group.get_payoff
        if Group.get_payoff == 0:
            player.payoff += C.payment_otherwise
