django管理员可根据其他字段中值在字段中选择选项

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

from .models import MyModel

class MyModelAdmin(admin.ModelAdmin):
    def formfield_for_foreignkey(self, db_field, request, **kwargs):
        if db_field.name == 'other_field':
            # 根据其他字段的值来选择选项
            other_field_value = request.GET.get('other_field_value')
            if other_field_value:
                kwargs['queryset'] = MyModel.objects.filter(other_field=other_field_value)
            else:
                kwargs['queryset'] = MyModel.objects.none()
            return ModelChoiceField(**kwargs)
        return super().formfield_for_foreignkey(db_field, request, **kwargs)

admin.site.register(MyModel, MyModelAdmin)
