Question

我正在尝试遍历我的所有Task模型对象，并检查他们是否有员工附加到他们身上。如果他们确实附加了员工，那么我想循环通过项目和用户之间的多种关系，并获得每个关联用户的电子邮件地址。我无法访问电子邮件字段。它一直让我“不可迭代”。或者＆＃34;全球名称＆＃39; users__type＆＃39;未定义，＆＃34;取决于我改变了什么。如果我的最终结果是一串用户电子邮件，我会遗漏一些简单的东西。

模型

from django.contrib.auth.models import User
from django.db import models

class CustomUser(models.Model):
   user = models.OneToOneField(User, blank=True, null=True)
   type = models.CharField(max_length=200, blank=True, null=True)
   email = models.CharField(max_length=100, blank=True, null=True)

//加上其他自定义用户字段//

class Task(models.Model):
   users = models.ManyToManyField(CustomUser, blank=True, null=true)

//加上其他任务栏//

我的其他课程

from django.models import Task
from django.models import CustomUser
from django.contrib.auth.models import User   

def emailTaskList():
   chosenPeople = []
   notchosenPeople = []

   chosenTask = Task.objects.filter(users__type = 'employee')
   for e in chosen:
       for d in e.users.all():
           chosenPeople.append(d.email)
   notchosenTask = Task.objects.filter(users__type != 'employee')
   for a in notchosen:
      for b in a.users.all():
           notchosenPeople.append(b.email)

   test = ' '.join(chosenPeople)

   connection = mail.get_connection()
   email = mail.EmailMessage('You have been assigned', test, [WebsiteEmail], [testRecipient])
   email.send()
   connection.close()
   return

使用exclude()方法代替!=比较：

notchosen = Task.objects.exclude(users__type='employee')

迭代和检查模型字段值QuerySets
