django表单save（）得到了一个意外的关键字参数？

Question

In my view:

image = simple_image_form.save(quiet=True)

my form:

class SimpleImageForm(forms.ModelForm):

    class Meta:
        model = Image
        fields = ("image",)

    def __init__(self, *args, **kwargs):
        self.request = kwargs.pop("request", None)
        super(SimpleImageForm, self).__init__(*args, **kwargs)

    def save(self, *args, **kwargs):
        kwargs["commit"]=False
        obj = super(SimpleImageForm, self).save(*args, **kwargs)
        if self.request and self.request.user:
            obj.member = self.request.user.get_current_member()
            obj.save(*args, **kwargs)
        return obj

when I save, I get the error:

save() got an unexpected keyword argument 'quiet'

I thought by placing **kwargs as a parameter, this wouldn't happen. What am I doing wrong?

Note: quiet is a parameter in the obj.save function used in condition checks, but is neither an attribute of the form or the obj itself

Answer 1

Yes, your override may handle the kwarg but you shouldn't do the same with the super call:

obj = super(SimpleImageForm, self).save(commit=False)

That should do. This happens because the ModelForm 's save method signature is:

def save(self, commit=True):

So it doesn't match the way you're calling it.

Hope this helps!

Answer 2

You need to have a field called quiet in order to save a value to that field. I don't see any reference to such a field in the form, so I'm guessing there isn't one in the model. Even if there is, you probably have to say reference it in the form since you're defining what parts of the model you're working with.
