Question

我有以下模型类

class GroupstageTournamentModel(ClusterableModel):
    #Score of TEAM 1
    team_1_first_halftime_score = models.PositiveSmallIntegerField(blank=True, default=None, verbose_name='Resultat 1. HZ')
    team_1_first_halftime_point = models.PositiveSmallIntegerField(blank=True, default=0, verbose_name='Punkte 1. HZ')
    team_1_second_halftime_score = models.PositiveSmallIntegerField(blank=True, default=None, verbose_name='Resultat 2. HZ')
    team_1_second_halftime_point = models.PositiveSmallIntegerField(blank=True, default=0, verbose_name='Punkte 2. HZ')
    team_1_shootout_score = models.PositiveSmallIntegerField(blank=True, default=None, verbose_name='Resultat Shootout')
    team_1_shootout_point = models.PositiveSmallIntegerField(blank=True, default=0, verbose_name='Schootout Punkte')
    team_1_total_score = models.PositiveSmallIntegerField(blank=True, default=0, verbose_name='Resultat Total')
    team_1_total_points = models.PositiveSmallIntegerField(blank=True, default=0, verbose_name='Punkte Total')

    #Score of TEAM 2
    team_2_first_halftime_score = models.PositiveSmallIntegerField(blank=True, default=None, verbose_name='Resultat 1. HZ')
    team_2_first_halftime_point = models.PositiveSmallIntegerField(blank=True, default=0, verbose_name='Punkte 1. HZ')
    team_2_second_halftime_score = models.PositiveSmallIntegerField(blank=True, default=None, verbose_name='Resultat 2. HZ')
    team_2_second_halftime_point = models.PositiveSmallIntegerField(blank=True, default=0, verbose_name='Punkte 2. HZ')
    team_2_shootout_score = models.PositiveSmallIntegerField(blank=True, default=None, verbose_name='Resultat Shootout')
    team_2_shootout_point = models.PositiveSmallIntegerField(blank=True, default=0, verbose_name='Schootout Punkte')
    team_2_total_score = models.PositiveSmallIntegerField(blank=True, default=0, verbose_name='Resultat Total')
    team_2_total_points = models.PositiveSmallIntegerField(blank=True, default=0, verbose_name='Punkte Total')

正如您所看到的，我PositiveSmallIntegerField的一些deafult=None是django.db.utils.IntegrityError: NOT NULL constraint failed: tournament_groupstagetournamentmodel.team_1_first_halftime_score。如果我保存这个模型，我会得到一个错误 Map<String, Optional<List<String>>> 我可以以某种方式忽略此错误并保存此模型吗？我特意把默认值设为无

我刚刚添加了null=True，就像@agconti建议的那样。感谢

team_1_first_halftime_score = models.PositiveSmallIntegerField(blank=True, default=None, null=True, verbose_name='Resultat 1. HZ')
team_1_first_halftime_point = models.PositiveSmallIntegerField(blank=True, default=0, verbose_name='Punkte 1. HZ')
team_1_second_halftime_score = models.PositiveSmallIntegerField(blank=True, default=None, null=True, verbose_name='Resultat 2. HZ')
team_1_second_halftime_point = models.PositiveSmallIntegerField(blank=True, default=0, verbose_name='Punkte 2. HZ')
team_1_shootout_score = models.PositiveSmallIntegerField(blank=True, default=None, null=True, verbose_name='Resultat Shootout')

期望PositiveSmallIntegerField的无类型值
