Question

我一直在寻找这个错误的解决方案，但对于其他人来说，这似乎是由一个稍微不同的原因造成的。我有一个类似于以下内容的models.py：

class MyModel(models.Model):
    something1 = models.IntegerField()
    something2 = models.CharField(max_length=256)
    something3 = models.CharField(max_length=256)

class MyModelForm(ModelForm):
    class Meta:
        model = MyModel
        fields = ('something1', 'something2',)

说我实际上并不想使用＆＃39; something3＆＃39;了。如果我删除它，甚至删除并重新同步数据库，我会收到错误

为MyModel指定的未知字段（something3）。

据我所知，当我使用

保存任何内容时，会发生这种情况

saveThis = MyModel(something1=x, something2=y)
saveThis.save()

任何想法是什么引发了这个错误？我甚至搜索了所有文件，以确保＆＃39; something3＆＃39;不在其中任何一个。这是追溯：
