将.xlsx文件导入模型，收到DateField的Integer超出范围错误：行号：1-超出范围的整数

Question

我正在尝试将电子游戏电子表格导入Django数据库。我已经设置了带有日期字段的模型，并且我相信我已经格式化了电子表格，使其与Django期望的格式匹配。

我正在使用Django import-export软件包。我试图在Django settings.py文件中手动设置格式，但这似乎无法解决。

  

models.py

from django.db import models
from multiselectfield import MultiSelectField
from django.urls import reverse


class Game(models.Model):

    boxArt = models.ImageField(default='questionmark.png', upload_to='boxart')
    title = models.CharField(max_length=100)
    genres = MultiSelectField(max_choices=5, choices=GENRES, blank=True)
    developers = MultiSelectField(max_choices=5, choices=DEVELOPERS, blank=True)
    platforms = MultiSelectField(max_choices=5, choices=PLATFORMS, blank=True)

    releaseDateJP = models.DateField(null=True,blank=True)
    releaseDatePAL = models.DateField(null=True,blank=True)
    releaseDateNA = models.DateField(null=True,blank=True)

    def __str__(self):
            return f'{self.title} Game'

    def get_absolute_url(self):
        return reverse('game_detail', kwargs={'pk': self.pk})

  

settings.py

DATE_INPUT_FORMATS = ['%Y-%m-%d']

电子表格的第一行如下所示：

我希望我的模型可以填充适当的数据；发布日期。但是我认为是第一个日期字段（releaseDateJP）导致了错误：

The above exception was the direct cause of the following exception:
