Django models Django ValueError:以10为基数的int（）的无效文本显示字符串字段内容，而不是使用ID值

请帮助我，我一直得到这个没有意义的错误

系统：PostGres DB上的Django 2.2（带夹层）

在我的模型中，我有一个外键字段：

class Keyword(models.Model):
    site = models.ForeignKey(Site, related_name='sitekeywords', on_delete=models.CASCADE)
    keyword = models.CharField("Keyword", max_length=64)

    def __str__(self):
        return "%s" % (self.keyword)

    class Meta:
        verbose_name_plural = "Keywords"

注意：关键字CharField不需要唯一。

关键字模型上的ID由Django创建和管理。此关键字模型与具有显式ID字段的站点模型相关：

id=models.AutoField（“id”，blank=False，primary\u key=True）

在Admin中，当我尝试编辑一个站点（该站点的关键字编辑为内联）时，有时会出现ValueError，显示：

基数为10的int（）的文本无效：“新元古代”

。。。 但是“新元古代”是一个关键字，代码应该使用关键字id，所以我很困惑。 注意，这只是一个示例，错误中的字符串可以是关系中的任何关键字\关键字字符串

这是我在forms.py中的内联表单：

class KeywordAdminForm(fforms.ModelForm):
    class Meta:
        model = Keyword
        fields = ['keyword']
        
        
class KeywordInlineAdminForm(KeywordAdminForm):
    pass

该错误表示在管理员表单生成fieldset.html时发生：
