我如何给`def formfield_for_manytomany`一个可编辑对象的id

from django import forms
from django.contrib.auth.forms import UserCreationForm
from django.contrib.auth.models import User
from django.forms.models import inlineformset_factory

class MyModelForm(forms.ModelForm):
    class Meta:
        model = MyModel
        fields = ['name', 'description', 'my_m2m_field']

    my_m2m_field = forms.ModelChoiceField(
        queryset=MyModel.objects.all(),
        widget=forms.Select(attrs={'id': 'my-m2m-field'})
    )

class MyModelFormSet(inlineformset_factory(MyModelForm)):
    class Meta:
        model = MyModel
        fields = ['name', 'description', 'my_m2m_field']

    def formfield_for_manytomany(self, db_field, request, **kwargs):
        if db_field.name == 'my_m2m_field':
            kwargs['widget'] = forms.Select(attrs={'id': 'my-m2m-field'})
            return forms.IDField(widget=forms.HiddenInput(), required=False)
        return super().formfield_for_manytomany(db_field, request, **kwargs)

class UserForm(UserCreationForm):
    class Meta:
        model = User
        fields = ['username', 'email', 'password1', 'password2']
