TypeError：__init __（）为参数'instance'获得了多个值

Question

我想同时在博客Web后端的编辑/（添加新帖子）中同时保留ckeditor和markdown，因此我修改了__init__，此后，我仍然可以打开编辑页面。但是，我单击“保存”按钮，出现此错误：TypeError: __init__() got multiple values for argument 'instance'

这是我删除后不会出现错误的部分：

blog / adminforms.py

class PostAdmin(forms.ModelForm):
    ....
    def __init__(self, instance=None, initial=None, **kwargs):
        initial = initial or {}
        if instance:
            if instance.is_md:
                initial['content_md'] = instance.content
            else:
                initial['content_ck'] = instance.content
        super().__init__(instance=instance, initial=initial, **kwargs)
    ....

我喜欢这里的解决方案： Django: multiple values for keyword argument 'initial' 通常来说，这是与我相同的问题。某种程度上，instance不会收到def __init__(self, instance=None, initial=None, **kwargs):传递给instance的信息，而是会传递给kwargs（仍然不会知道为什么），然后intance默认为None，所以有两个inastance参数，第一个实例默认为None，第二个实例{{1 }}位于instance中，这是我想传递的真实

以便我做些什么来解决它：

kwargs
