django必需的文件字段驗證

Question

使用django形式，其中我有兩個文件上傳字段，一個用於藝術家圖像，另一個用於事件海報，這兩個字段都是必需的。

class CreateEventStepFirstForm(forms.Form):
    event_title = forms.CharField(required = True, max_length=20, widget=forms.TextInput(attrs={
        'class' : 'custome-input promote-input', 
        'autocomplete' : 'off',
        'data-empty-message':'This field is required' 
    }))
    ticket_title = forms.CharField(required = True, max_length=225, widget=forms.TextInput(attrs={
        'class' : 'custome-input promote-input', 
        'autocomplete' : 'off',
        'data-empty-message':'This field is required' 
    }))
    artist_image = forms.FileField(required = True, widget=forms.FileInput(attrs={
        'class' : 'upload-img',
        'data-empty-message':'Please upload artist image, this field is required'
    }))
    event_poster = forms.FileField(required = True, widget=forms.FileInput(attrs={
        'class' : 'upload-img',
        'data-empty-message':'Please upload artist image, this field is required'
    }))

問題在於，除了這兩個文件字段之外，所有字段均已正確驗證，當我同時選擇artist_image和event_poster的圖像時，即使我同時選擇了兩個圖像，也不會驗證這些字段並給出“此字段為必填”錯誤。

您需要添加request.FILES ，如下所示：

form = CreateEventStepFirstForm(request.POST, request.FILES)
