我在标题中写了一个错误。我有两个使用InlinePanel s的页面模型：
class TournamentPage(Page):
starts_at = models.DateTimeField(blank=True)
ends_at = models.DateTimeField(blank=True)
content_panels = Page.content_panels + [
FieldPanel('starts_at'),
FieldPanel('ends_at'),
InlinePanel(
'groupstage_tournament_relationship', label="Goups",
panels=None, min_num=1),
InlinePanel(
'final_phase_relationship', label="Finals",
panels=None, min_num=1),
]
parent_page_types = ['home.HomePage']
def __str__(self):
return self.title
class ScreencastPage(Page):
content_panels = Page.content_panels + [
InlinePanel(
'groupstage_screencast_relationship', label="Playing First",
panels=None, max_num=1),
InlinePanel(
'final_phase_relationship', label="Playing Next",
panels=None, max_num=1),
]
parent_page_types = ['home.HomePage']
subpage_types = []
def __str__(self):
return self.title
如果我点击添加新的锦标赛页面或Screencast页面，我会收到此错误：
Exception Type: ValueError
Exception Value: invalid literal for int() with base 10: ''

更新
我不确定这可能是原因，但我会说，当我进行迁移时，我需要输入''作为某些字段的默认值。也许python在没有必要的地方规定了它们。我是用控制台做的。
这是我的GroupstageTournamentModel和FinalphaseTournamentModel。关系模型也包括在内。
