Question

            class PostForm(forms.ModelForm):
                description = forms.CharField(widget=PagedownWidget(show_preview=False))
                class Meta:
                    model = Post
                    fields = [
                        'title',
                        'image',
                        'video',
                        'description',
                        'public',
                        'tags',
                        ]

我试图绕过“视频”所需的字段，但很难这样做。任何建议将不胜感激。

这是我的models.py，希望有助于知道如何继续这样做。

从the docs看起来它应该支持从版本0.3以来的空，我建议尝试

video = EmbedVideoField(null=True,blank=True)

文档说它应该像URL字段一样运行，所以只需标准符号即可。

祝你好运！
