在django中是否可以将表单值存储在下拉列表中

from django import forms

class MyForm(forms.Form):
    my_choices = (
        ('option1', 'Option 1'),
        ('option2', 'Option 2'),
        ('option3', 'Option 3'),
    )
    my_field = forms.ChoiceField(choices=my_choices)

from django import forms
from .models import MyModel

class MyForm(forms.Form):
    my_field = forms.ModelChoiceField(queryset=MyModel.objects.all())

from django.shortcuts import render
from .forms import MyForm

def my_view(request):
    form = MyForm()
    return render(request, 'my_template.html', {'form': form})

<form method="post">
    {% csrf_token %}
    {{ form.as_p }}
    <input type="submit" value="Submit">
</form>
