Question

我在学习大坝的同时,正在建造一个足球预测器,其模式如下:

class Team(models.Model):
     Name = models.CharField(max_length=30)

class Fixture(models.Model):
     HomeTeam = models.ForeignKey(Team, related_name= HomeTeamRef )
     AwayTeam = models.ForeignKey(Team, related_name= AwayTeamRef )
     HomeTeamScore = models.IntegerField(null=True, blank=True)
     AwayTeamScore = models.IntegerField(null=True, blank=True)
     Date = models.DateField()

class Player(models.Model):
     User = models.ForeignKey(User)
         DefaultHomeScore = models.IntegerField()
         DefaultAwayScore = models.IntegerField()

class Prediction(models.Model):
     Fixture = models.ForeignKey(Fixture)
     HomeTeamScore = models.IntegerField()
     AwayTeamScore = models.IntegerField()
     Date = models.DateTimeField()
     Player = models.ForeignKey(Player)

我有许多固定装置物体有人居住,并且一直在使用基于预测模型的模型表格,以便形成一种使用户能够进入计分的观点。

问题是,他们必须选择与预测有关的哪一种办法。我愿预先欢迎这一点,以便他们获得固定装置清单,并刚刚进入屋顶和离层。这需要预先策划。 Fixture field and Prediction. 运动员们,但我对如何做到这一点感到不满?

任何帮助都受到高度赞赏。

Edit: The problems seems to be how to pass multiple instances of Fixture into a Prediction model formset, I have seen examples of passing one but would like to do this all in one go. I also would like the user to be able to make one Prediction per Fixture.

Answer 1

I think this is what you are looking for: https://docs.djangoproject.com/en/1.7/topics/forms/formsets/#using-initial-data-with-a-formset

你的法典将考虑这样的问题:

initial_data = []
for fixture in fixtures:
    initial_data.append({ Player :player, Fixture :fixture})

formset = MyPredictionFormset(initial=initial_data)

P.S. Not to be pedantic, but their field name are not PEP 8 compliance. 他们应该受到强调,但你也发出呼吁。 ( http://www.python.org/dev/peps/pep-0008/)
