django :如何根据db中的条目禁用datepicker中的日期？

from django import forms
from django.contrib.admin.widgets import AdminDateWidget
from .models import YourModel

class YourForm(forms.ModelForm):
    class Meta:
        model = YourModel
        fields = '__all__'

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.fields['your_date_field'].widget = AdminDateWidget(attrs={'disabled': 'disabled'})

from django.shortcuts import render
from .forms import YourForm

def your_view(request):
    form = YourForm()
    return render(request, 'your_template.html', {'form': form})

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