我无法理解如何将其他信息与现有的Django列表相关联,以及我是否应该在我的模板或视图中以某种方式执行此操作。请参阅以下方案:
class Team(models.Model):
team_name = models.CharField(max_length=200)
例如,在我看来,我正在检索所有体育比赛的列表并将其返回:
def get_teams(request):
teams = Team.objects.all()
context = RequestContext(request, {
'teams': teams,
})
return context
我想向团队添加一些统计数据,然后我可以通过以下方式访问我的模板:
def get_teams(request):
teams = Team.objects.all()
for team in teams:
team_win_percent(team)
team_lose_percent(team)
context = RequestContext(request, {
'teams': teams,
})
return context
def team_win_percent(team)
team_win_rate = [calculations here]
return team_win_rate
def team_lose_percent(team)
team_lose_rate = [calculations here]
return team_lose_rate
我正在努力理解的是如何将team_win_percentage和team_lose_percentage添加到我的团队列表中,以便我可以在我的模板中引用它们?
非常感谢任何指导!

你也可以为一些记录添加一些字段到模型查询结果,可以从模板中访问
{% for team in teams %}
team win percentage = {{ team.team_win_percent }}
team lose percentage = {{ team.team_lose_percent }}
{% endfor %}
在模板中
sudo docker build -t foo/bar .
sudo docker run foo/bar /bin/bash /path/to/my/script/test_report.sh

你必须把它写成一个模型方法;
class Team(models.Model):
team_name = models.CharField(max_length=200)
def team_win_percent(self):
#self = team object
team_win_rate = [calculations here]
return team_win_rate
def team_lose_percent(self):
#self = team object
team_lose_rate = [calculations here]
return team_lose_rate
在模板中:
{% for team in teams %}
team win percentage = {{ team.team_win_percent }}
team lose percentage = {{ team.team_lose_percent }}
{% endfor %}
