[BUG] AutocompleteSelect widget broken after moving from django 2.2 to django 3.2

[exo]

Hello :) After upgrading Django version to 3.2, widget AutocompleteSelect that I use in django admin panel (to have a drop-down from which I can choose an object) is broken.

The error I see is

    AttributeError at /admin/question/
    'QuerySet' object has no attribute 'name'

AutocompleteSelect inherits from AutocompleteMixin

When I compare AutocompleteMixin for django 3.2 and django 2.2
​https://github.com/django/django/blob/3.2.13/django/contrib/admin/widgets.py#L410-L412
​https://github.com/django/django/blob/2.2.7/django/contrib/admin/widgets.py#L411

I see that they added new attributes

    'data-app-label': self.field.model._meta.app_label,
    'data-model-name': self.field.model._meta.model_name,
    'data-field-name': self.field.name,

in django 3.2
but there is no name on self.field and probably that's why I get this error.

The code looks like this

view.py

    from django.forms import ModelChoiceField
    from django import forms
    from django.contrib import admin
    from django.contrib.admin.widgets import AutocompleteSelect

    class QuestionChoiceField(ModelChoiceField):
        widget = AutocompleteSelect(Question.objects.all(), admin.site)
    
    
    class QuestionExportForm(forms.Form):
        question = QuestionChoiceField(queryset=Question.objects.all(), required=True)
    
        def clean_question(self):
            return self.cleaned_data["question"]
    
    
    class QuestionExportView(FormView):
        template_name = "admin/question_export.html"
        form_class = QuestionExportForm
        success_url = "/admin/"
    
        def form_valid(self, form):
            question = form.cleaned_data.get("question")
            return generate_response(question)

models.py

    from django.db import models


    class Question(models.Model):
        question_text = models.CharField(max_length=200)
        pub_date = models.DateTimeField('date published')

templates/admin/question_export.html

    {% block content %}
        <div id="content-main">
          <p>Select question to export:</p>
            <form method="post" enctype="multipart/form-data">
                {% csrf_token %}
                <table>
                    {{form.as_table}}
                </table>
                <div class="submit-row">
                    <input type="submit" value="Export Question" />
                </div>
            </form>
        </div>
        {{form.media}}
    {% endblock %}

How can I approach this issue? Any help would be appreciated :)!
