Django | 將 model 字段的默認值設置為登錄用戶的 email

Question

我正在嘗試在我的 django 網站中顯示用戶特定的內容，而我距離完成此任務僅一步之遙。 在models.py中，我需要contact_email字段的默認值是登錄用戶的email。 我已經嘗試了很多方法來做到這一點，但還沒有奏效。

模型.py

class Account(AbstractUser):
    email = models.EmailField(verbose_name='email', max_length=60, unique=True)
    name = models.CharField(max_length=45, unique=False)
    username = models.CharField(max_length=100, default='')
    date_joined = models.DateTimeField(verbose_name='date joined', auto_now_add=True)
    last_login = models.DateTimeField(verbose_name='last login', auto_now=True)
    is_admin = models.BooleanField(default=False)
    is_active = models.BooleanField(default=True)
    is_staff = models.BooleanField(default=False)
    is_superuser = models.BooleanField(default=False)
    is_employee = models.BooleanField(default=True, verbose_name='Are you using FilmLink as an employee?')

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['name', 'is_employee']

    objects = MyAccountManager()

    class Meta:
        permissions = [
            ("post_jobs", "Can post jobs"),
        ]

    def __str__(self):
        return self.name

    def has_perm(self, perm, obj=None):
        return True

    def has_perms(self, perm):
        return True

    def has_module_perms(self, app_label):
        return True

    @property
    def is_staff(self):
        return self.is_admin

class Job(models.Model):
    company = models.CharField(max_length=40, null=True, verbose_name="Company/Employer")
    description = models.TextField(null=True)
    role = models.CharField(max_length=25)
    area_of_filming = models.CharField(max_length=50, verbose_name="Area Of Filming", default="")
    contact_email = models.EmailField(verbose_name='Contact Email', max_length=60, default='')#stuck on setting this default
    created = models.DateTimeField(auto_now_add=True)
    user = models.ForeignKey(settings.AUTH_USER_MODEL, null=True, on_delete=models.CASCADE)

    def __str__(self):
        return self.company

視圖.py

@login_required(login_url='login')
def manage_jobs(request):
    if request.user.is_employee:
        return redirect('home')
    else:
        form = JobForm(request.POST)
        if form.is_valid():
            form.save()
        jobs = Job.objects.filter(contact_email = request.user.email)
        context = {"form":form, "jobs":jobs}
        return render(request, 'employer/manage-jobs.html', context)

我不相信你可以這樣設置默認值。

相反，您應該做的是，在創建Job object 並將其保存到數據庫時，您自己提供contact_email的值。

然后，您可以稍后根據contact_email字段過濾Job條目。

# Creating a Job object
job = Job()
job.column1 = value
job.contact_email = request.user.email

# In other view, where you need to filter
jobs = Job.objects.filter(contact_email=request.user.email)

一個隨機的想法：

如果您想要該contact_email字段的唯一原因是能夠應用過濾器來獲取該特定用戶的所有 Job 對象，那么您也可以使用user字段進行過濾。

jobs = Job.objects.filter(user=request.user)
context = {"form":form, "jobs":jobs, 'contact_email': request.user.email}
return render(request, 'employer/manage-jobs.html', context)
