问题描述

您好,我正在使用日期进行搜索查询。但是我遇到了运行时错误。

Hello i'm using dates for search queries. But i am getting runtime error.

RuntimeWarning:DateTimeField Jobs.job_created_on在激活时区支持时收到了一个简单的日期时间(2019-01-17 00:00:00)

RuntimeWarning: DateTimeField Jobs.job_created_on received a naive datetime (2019-01-17 00:00:00) while time zone support is active.

Views.py

class JobListView(LoginRequiredMixin, generic.TemplateView):
    template_name = 'admin/jobs/job.html'

    def get(self, request, *args, **kwargs):
        context = super(JobListView, self).get_context_data(**kwargs)

        if 'status' in request.GET:
            form = JobSearchForm(request.GET)

            if form.is_valid():
                status = form.cleaned_data['status']
                start_date = form.cleaned_data['start_date']
                end_date = form.cleaned_data['end_date']
                company = self.request.user.userprofile.user_company

                lookups = (Q(job_company=self.request.user.userprofile.user_company) ) 

                if start_date:
                    lookups = lookups | Q(job_created_on__gte=start_date)
                if end_date:
                    lookups = lookups | Q(job_created_on__lte=end_date)

                jobs=Jobs.objects.exclude(job_is_deleted = True).filter(lookups)

        else:
            form = JobSearchForm()
            company_name = self.request.user.userprofile.user_company
            jobs = Jobs.objects.exclude(
                                job_is_deleted = True
                            ).filter(
                                job_company=self.request.user.userprofile.user_company
                            )

        return render(request, self.template_name, {'form': form, 'jobs': jobs})

Forms.py

ACTIVE_CHOICES = (
    ('AllStatus', 'Select Status'),
    ('Active', 'Active'),
    ('InActive', 'Inactive'),
)
class JobSearchForm(forms.Form):
    start_date = forms.DateField(label=False)
    end_date = forms.DateField(label=False)
    status = forms.ChoiceField(choices=ACTIVE_CHOICES, label=False, initial="")

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        self.fields['start_date'].widget.attrs['placeholder'] = 'Start Date'
        self.fields['end_date'].widget.attrs['placeholder'] = 'End Date'
        # self.fields['status'].initial = 'Select Status'
        self.fields['start_date'].widget.attrs['class'] = 'job_date'
        self.fields['end_date'].widget.attrs['class'] = 'job_date'
        self.fields['start_date'].required=False
        self.fields['end_date'].required=False

Models.py-工作模型

Models.py - Jobs Models

class Jobs(models.Model):
    job_created_on = models.DateTimeField(auto_now_add=True)
    job_created_by = models.ForeignKey(User, on_delete=models.CASCADE, related_name='job_created_bys')
    job_updated_on = models.DateTimeField(auto_now=True)
    job_updated_by = models.ForeignKey(User, on_delete=models.CASCADE, related_name='job_updated_bys')
    job_is_deleted = models.BooleanField(default=False)
    job_deleted_at = models.DateTimeField(blank=True, null=True)
    ACTIVE = 'Active'
    INACTIVE = 'Inactive'
    JOB_ACTIVE_CHOICES = (
        (ACTIVE, 'Active'),
        (INACTIVE, 'Inactive'),
    )
    job_status = models.CharField(
        max_length=8,
        choices=JOB_ACTIVE_CHOICES,
        default=INACTIVE,
    )

为什么给我运行时警告-RuntimeWarning:DateTimeField Jobs.job_created_on收到的日期时间很短(2019-01-17 00: 00:00)时区支持处于活动状态。

Why it is giving me runtime warning - RuntimeWarning: DateTimeField Jobs.job_created_on received a naive datetime (2019-01-17 00:00:00) while time zone support is active.

推荐答案

突出显示@dirkgroten,您的表单将返回 Date (没有时区)到模型中的时区感知 DateTime 。这是使用 date 查找:

As @dirkgroten highlighted, your form returns a Date, which doesn't have a timezone, to a timezone-aware DateTime in your model. Here is how fix that with the date lookup:

if start_date:
    lookups = lookups | Q(job_created_on__date__gte=start_date)
if end_date:
    lookups = lookups | Q(job_created_on__date__lte=end_date)
