Python 如何在oTree中创建多项选择题？

我想知道在otree中是否可以有一道选择题。类似于单选按钮，但它允许您选择多个内容。 我想的是：

问题：以下陈述清单包含三个正确陈述和三个错误陈述。请选择三条正确的语句：

• 报表1
• 报表2
• 报表3
• 报表4
• 报表5
• 报表6

---

为此，您可以使用

otree\u models.models.multipleechoiceformfield

，如下所示：

在

models.py中

：

from otree.api import BasePlayer
from otree_tools.models import fields as tool_models

class Player(BasePlayer):

    correct_statements = tool_models.MultipleChoiceModelField(label="Please select the three correct statements",
                                                              min_choices=3, max_choices=3)

from ._bultin import Page

class ExamplePage(Page):

    form_model = "player"
    form_fields = ["correct_statements"]

    def correct_statements_choices(self):
         """Return the list of statements to choose from."""
         return ["Statement 1", "Statement 2", "Statement 3",
                 "Statement 4", "Statement 5", "Statement 6"]

在

pages.py

中：

from otree.api import BasePlayer
from otree_tools.models import fields as tool_models

class Player(BasePlayer):

    correct_statements = tool_models.MultipleChoiceModelField(label="Please select the three correct statements",
                                                              min_choices=3, max_choices=3)

from ._bultin import Page

class ExamplePage(Page):

    form_model = "player"
    form_fields = ["correct_statements"]

    def correct_statements_choices(self):
         """Return the list of statements to choose from."""
         return ["Statement 1", "Statement 2", "Statement 3",
                 "Statement 4", "Statement 5", "Statement 6"]

在

ExamplePage.html

中，只需包含表单字段：

{% extends "global/Page.html" %}
{% load otree %}

{% block content %}
The following list of statements contains three correct statements and three false statements. 

{% formfield player.correct_statements %}

{% next_button %}

{% endblock %}

是的。请看这里：-这是一个链接到官方的oTree集团论坛，在那里讨论了这一点。事实上，它只是一个简单的django多项选择小部件
