Creating a ModelForm without either the 'fields' attribute or the 'exclude' attribute is prohibited; form ResumeForm needs updating.

django 報錯

django.core.exceptions.ImproperlyConfigured: Creating a ModelForm without either the 'fields' attribute or the 'exclude' attribute is prohibited; form ResumeForm needs updating.

一搜網上的回答大都是說加上

fields = '__all__'

看下django.forms.models 中判斷報錯的源碼如下

            # If a model is defined, extract form fields from it.
            if opts.fields is None and opts.exclude is None:
                raise ImproperlyConfigured(
                    "Creating a ModelForm without either the 'fields' attribute "
                    "or the 'exclude' attribute is prohibited; form %s "
                    "needs updating." % name
                )

意思就是定義的model沒字段 但我有的啊

class ResumeForm(forms.ModelForm):
    class Meta:
        model = Resume
        field = ('title', 'body',)

再仔細一看 fields 寫成 field ...
