Question

在此模型中，我有一个名为 UserTypes 的模型，我将User用作OneToOne字段，并且 UserTypes 模型与 User 模型内联。我创建此模型的目的是为用户提供状态，就像我们进行is_staff = True一样。现在，我想在同一项目的另一个应用程序

中显示另一个名为Order的模型中显示其staff_status =“ Delivery Boy”的所有用户

model.py（app1）

class UserTypes(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    staff_choices = (
        ('', ''),
        ('Admin', 'Admin'),
        ('Chef', 'Chef'),
        ('Delivery Boy', 'Delivery Boy'),
    )
    staff_status = models.CharField(max_length=15, choices=staff_choices, default=staff_choices[0][0]) 

    def __str__(self):
        return self.staff_status

model.py（app2）

class Order(models.Model):
    name = models.CharField(max_length=60)
    email = models.EmailField(max_length=60,default=None, blank=True)
    mobile_no = models.CharField(max_length=13, default=None) 
    address = models.CharField(max_length=150)
    created = models.DateTimeField(auto_now_add=True)
    updated = models.DateTimeField(auto_now=True)
    status_choices = (
        ('In Queue', 'In Queue'),
        ('Processing', 'Processing'),
        ('Ready', 'Ready'),
        ('Delivered', 'Delivered'),
        ('Paid', 'Paid'),
        ('Cancelled', 'Cancelled'),
    ) 
    status = models.CharField(max_length=15, choices=status_choices, 
            default=status_choices[0][0])
    total = models.DecimalField(max_digits=10, decimal_places=2,default=0)


class Meta:
    ordering = ('created', )


def __str__(self):
    return 'Order {}'.format(self.id)


def get_total(self):
    return sum(item.get_cost() for item in self.items.all())

在app2 models.py文件中添加一个字段以将用户类型存储在订单表中：

from app1.models import UserTypes

user = models.OneToOneField(UserTypes, on_delete=models.CASCADE)

将此代码添加到您的app2的admin.py文件中：

from app1.models import UserTypes
from .models import Order

class OrderAdmin(admin.ModelAdmin):
    def get_form(self, request, obj=None, **kwargs):
        form = super(OrderAdmin,self).get_form(request, obj,**kwargs)
        # form class is created per request by modelform_factory function
        # so it's safe to modify
        # we modify the the queryset
        form.base_fields['user'].queryset = 
        form.base_fields['user'].queryset.filter(staff_choices='Delivery Boy')
        return form
admin.site.register(Order, OrderAdmin)
