Question

这是我的模特

class Company(models.Model):
    user    = models.ForeignKey(settings.AUTH_USER_MODEL,related_name="Company_Owner",on_delete=models.CASCADE,null=True,blank=True)
    name    = models.CharField(max_length=50,blank=False)
    auditor = models.ManyToManyField(settings.AUTH_USER_MODEL,related_name='main_auditor',blank=True)

我想执行一个查询，该查询将显示与特定审核员相关的公司的列表...

如何在Django中使用settings.AUTH_USER_MODEL查询？

有人知道吗？

请帮助

Answer 1

您可以使用get_user_model()这样操作：

from django.contrib.auth import get_user_model

User = get_user_model()

first_user = User.objects.first()

first_user.Company_Owner.all()  # will get all companies associated with the User

Answer 2

您的模型关系命名不正确，请更改related_name参数，因为它们需要表示您正在获取Company对象：

class Company(models.Model):
    user    = models.ForeignKey(settings.AUTH_USER_MODEL,related_name="owned_companies",on_delete=models.CASCADE,null=True,blank=True)
    name    = models.CharField(max_length=50,blank=False)
    auditor = models.ManyToManyField(settings.AUTH_USER_MODEL,related_name='audited_companies',blank=True)

一旦您有user（例如user = self.request.user）就可以执行以下操作：

user.owned_companies.all()  # companies for which the user is the owner
user.audited_companies.all()  # companies for which the user is a main auditor
user.owned_companies.filter(auditor=user)  # companies of which the user is both owner and auditor

Django：如何使用设置执行查询。AUTH_USER_MODEL？
