我希望能夠將我的用戶模型、配置文件模型和單獨的模型聯系在一起。我當前的模型結構如下所示：class Profile(models.Model): COORDINATOR = 1 LEADER = 2 ADMIN = 3 ROLE_CHOICES = ( (COORDINATOR, 'Coordinator'), (LEADER, 'Leader'), (ADMIN, 'Admin'), ) user = models.OneToOneField(User, on_delete=models.CASCADE) team = models.ForeignKey(Team, on_delete=models.PROTECT,null=True) role = models.PositiveSmallIntegerField(choices=ROLE_CHOICES, null=True, blank=True) agent_code = models.CharField(max_length=15, null=True, blank=True)class DailyReports(models.Model): agent_code = models.CharField(max_length=15, blank=True, null=True) product = models.CharField(max_length=15) num_free = models.IntegerField(blank=True, null=True) apps_submitted = models.IntegerField(blank=True, null=True) apps_activated = models.IntegerField(blank=True, null=True) prem_submitted = models.DecimalField(max_digits=20, decimal_places=2,blank=True, null=True) date = models.DateField(auto_now=False,auto_now_add=False,null=True,blank=True)我可以涉及Profile和User，但我試圖涉及Profile到DailyReports上agent_code，然后涉及到User模型。因此，類似于以下內容： test_query = DailyReports.objects.filter(product__in=['LT15', 'LT121']) \ .values('agent_code') \ .annotate(premium=Sum('prem_submitted')) \ .order_by('-premium') \我得到了預期的輸出：{'agent_code': 'ABC123', 'premium': Decimal('50015.87')} {'agent_code': 'DEF456', 'premium': Decimal('44818.20')} {'agent_code': 'GHI789', 'premium': Decimal('35322.35')}...但我也想從得到的信息Profile基礎上agent_code，再對相關的User基礎上訂立的相關信息agent_code之間的Profile和DailyReports，這樣，我的輸出如下所示：{'agent_code': 'ABC123', 'premium': Decimal('479872.55'), user.profile.first_name, user.profile.last_name, profile.user_id, profile.role} {'agent_code': 'DEF456', 'premium': Decimal('448118.20'), user.profile.first_name, user.profile.last_name, profile.user_id, profile.role}

如果一個配置文件將鏈接到多個 DailyReports 最佳設置將必須是
class Profile(models.Model):
COORDINATOR = 1
LEADER = 2
ADMIN = 3
ROLE_CHOICES = (
(COORDINATOR, 'Coordinator'),
(LEADER, 'Leader'),
(ADMIN, 'Admin'),
)
user = models.OneToOneField(User, on_delete=models.CASCADE)
team = models.ForeignKey(Team, on_delete=models.PROTECT,null=True)
role = models.PositiveSmallIntegerField(choices=ROLE_CHOICES, null=True, blank=True)
# agent_code = models.CharField(max_length=15, null=True, blank=True) # <-- Remove the agent code from the profile model.
DailyReports 與 Profile 是多對一的關系。
class DailyReports(models.Model):
profile = models.ForeignKey('Profile', related_name='daily_reports')
agent_code = models.CharField(max_length=15, blank=True, null=True)
product = models.CharField(max_length=15)
num_free = models.IntegerField(blank=True, null=True)
apps_submitted = models.IntegerField(blank=True, null=True)
apps_activated = models.IntegerField(blank=True, null=True)
prem_submitted = models.DecimalField(max_digits=20, decimal_places=2,blank=True, null=True)
date = models.DateField(auto_now=False,auto_now_add=False,null=True,blank=True)
獲取配置文件的 DailyReports 列表
profile = Profile.objects.prefetch_related('daily_reports').first()
profile.daily_reports.all()
通過配置文件報告查詢
qs = (
profile.daily_reports.filter(product__in=['LT15', 'LT121'])
.annotate(premium=Sum('prem_submitted'))
.values_list('agent_code', 'premium', 'profile__first_name', 'profile__last_name', 'profile__user_id', 'profile__role', named=True)
.order_by('-premium')
)
results = [
{
'agent_code': report.agent_code,
'premium': report.premium
'first_name': report.profile__first_name,
'last_name': report.profile__last_name,
'user_id': report.profile__user_id,
'role': report.profile__role
} for report in qs
]
## {'agent_code': 'ABC123', 'premium': Decimal('479872.55'), ...}
