得到一个属性错误，将函数显示为错误或属性。我尝试过解决这个问题，但是它不起作用，我删除了所有迁移的文件，并再次运行python manage.py makemigrations和admin.py命令，但仍然在admin.py中显示相同的错误代码。

# Register your models here.
from django.contrib import admin
from .models import *
# Register your models here.
@admin.register(User)
class UserAdmin(admin.ModelAdmin):
    list_display=('user_id','username','password','name','email_id','contact','address')

@admin.register(Orders)
class OrdersAdmin(admin.ModelAdmin):
    list_display=('oid','parcel_info','parcel_qty','parcel_weight','unit_mass','desti')

views.py中的代码

        if userm is not None:
            login(request,userm)
            messages.success(request,"You have login successfully...")
            return redirect("home")
        else:
            messages.error(request,"Invalid Username or password...")
            return redirect("login")
    else:
        return render(request,'base.html')

    else:

        return render(request,'register.html',{'form':fm})

问题是您的Orderbook表单不是ModelForm，它没有保存方法，所以只需用下面的代码替换它。

class Orderbook(forms.ModelForm):
    class Meta:
        model = Orders
        fields = '__all__'

您的Orderbook是一个表单，您不能保存表单，您需要保存它的数据

def Orderreg(request):
if request.method=='POST':
    fm=Orderbook(request.POST)
    if fm.is_valid():
       #your variable here which you pass
       variable = fm.cleaned_data['variable']

然后，您需要使用这个变量来查询一个对象，只有这样，您才能保存()这个对象。
