我有以下定制模式字段:
script = S3EnabledFileField(bucket=settings.MEDIA_BUCKET, upload_to=...)
在我的表格中,我用的是模范表格:
class CreateProductionForm(ModelForm):
name = forms.CharField(required=True)
class Meta:
model = Production
fields = ( name , script )
这使得 < code> strime 成为要求的窗体字段。 我将如何使脚本成为可选字段( 我不知道如何定义定制模型字段的窗体字段)。
修改模型而不是窗体,并添加 blank=True :
script = S3EnabledFileField(bucket=settings.MEDIA_BUCKET, upload_to=..., blank=True)
