DJANGO如何从窗体内部访问当前模型实例

Question

class EditAdminForm(forms.ModelForm):
    password = username.CharField(widget=forms.TextInput())
    password = forms.CharField(widget=forms.PasswordInput())
    password_confirm = forms.CharField(widget=forms.PasswordInput(), initial=???)

您可以在EditAdminForm中定义__init__方法。在

比如：

class EditAdminForm(forms.ModelForm):
    username = forms.CharField(widget=forms.TextInput())
    password = forms.CharField(widget=forms.PasswordInput())
    def __init__(self, initial_from, data=None, initial=None)
        sefl.fields['password_confirm'] = forms.CharField(widget=forms.PasswordInput(), initial=initial_from)
