django - 类型错误 : __init__() got an unexpected keyword argument 'show_preview'

Question

我在 Django 1.9 中遇到这个错误

in PostForm
    content = forms.CharField(widget=PagedownWidget(show_preview=False))
TypeError: __init__() got an unexpected keyword argument 'show_preview'

表单.py

class PostForm(forms.ModelForm):
    content = forms.CharField(widget=PagedownWidget(show_preview=False))
    publish = forms.DateField(widget=forms.SelectDateWidget)
    class Meta:
        model = Post
        fields = [
            "title",
            "content",
            "image",
            "draft",
            "publish",
        ]

使用attrs-- (Django Doc)将值传递给小部件的参数

widget=PagedownWidget(<b>attrs={"show_preview":False}</b>)
