如何显示在模板中选择 true 的 Django BooleanFields？

Question

我创建了一个模型对象。这个对象有几个布尔字段。

# models.py

class TeamCharacteristic(models.Model):
     team = models.ForeignKey('Teams',on_delete=models.CASCADE)
     power1 = models.BooleanField(null=True, blank=True)
     power2 = models.BooleanField(null=True, blank=True)
     power3 = models.BooleanField(null=True, blank=True)
     power4 = models.BooleanField(null=True, blank=True)
     power5 = models.BooleanField(null=True, blank=True)

class Meta:
     verbose_name = 'Team style'
     verbose_name_plural = 'Teams style'

def __str__(self):
     return "{} 's style".format(
         self.team,
     )

有些是对的，有些是错的。我只想显示模板中具有正确值的字段。我怎样才能以更短的方式执行此操作而不是单独检查每个字段？

# views.py
from django.shortcuts import render, get_object_or_404
from .models import Matches
from denemee.apps.home.models import TeamCharacteristic


def matches_details(request, page_id=None, team=None, **kwargs):
    m_detail = get_object_or_404(Matches, id=page_id)
    home_team_chr = get_object_or_404(TeamCharacteristic, team=m_detail.h_team)
    away_team_chr = get_object_or_404(TeamCharacteristic, team=m_detail.a_team)
    payload = {
        'm_detail': m_detail,
        'home_team_chr': home_team_chr,
        'away_team_chr': away_team_chr
    }
    return render(request, 'match_detail.html', payload)

Answer 1

您可以将 home_team_chr 和 home_team_chr 作为 序列化 对象发送，然后遍历字段和检查布尔值中的真值。
