TypeError: __init__() got an unexpected keyword argument 'show_preview'

Question

I am getting this error in Django 1.9

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

forms.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",
        ]

Use attrs-- (Django Doc) parameter to pass the values to widget

widget=PagedownWidget(attrs={"show_preview":False})
