python - Use a form with a custom __init__ in Django Admin

Question

I use the code below to add a custom form in Django Admin:

class MyAdmin(admin.ModelAdmin):
    form = MyForm

However, the form has an overridden constructor:

def __init__(self, author, *args, **kwargs):
    super(MyForm, self).__init__(*args, **kwargs)
    self.author = author

How could I pass the Admin current user to the form constructor?

Answer 1

change your MyAdmin class like this:

class MyAdmin(admin.ModelAdmin):
    form = MyForm

    def get_form(self, request, **kwargs):
        form = super(MyAdmin, self).get_form(request, **kwargs)
        form.current_user = request.user
        return form

You can now access the current user in your forms.ModelForm by accessing self.current_user.

def __init__(self, author, *args, **kwargs):
    super(MyForm, self).__init__(*args, **kwargs)
    self.author = author
    # access to current user by self.current_user
