结合django-filter DateTimeFromToRangeFilter和DateTimeInput（datepicker）

问题描述 投票：0回答：1

使用django_filter和datetimeinput作为日期选择器，我试图添加日期和时间输入，FROM和TO字段。

我只能使用django表单中的一个字段或来自django过滤器DateTimeFromToRangeFilter的dateinput而没有显示日期选择器（只是手动文本输入）。

这是带有日期选择器的一个字段的filter_model.py。

from app.models.api_status import ApiStatus
import django_filters
from django import forms

class DateTimeInput(forms.DateTimeInput):
    input_type = 'date'

    # working solution for just 1 date field
class ApiStatusFilter(django_filters.FilterSet):
    date_time = django_filters.DateFilter(
        label=('With start date'),
        lookup_expr=('icontains'), # use contains,
        widget=DateTimeInput()
    )
    class Meta:
        model = ApiStatus
        fields = ['id', 'date_time']

图片显示了可点击的日期选择器弹出窗口。

这是我的filter_model.py，用于两个字段，FROM和TO没有日期选择器。

from app.models.api_status import ApiStatus
import django_filters
from django import forms

class DateTimeInput(forms.DateTimeInput):
    input_type = 'date'


class ApiStatusFilter(django_filters.FilterSet):
    date_time =django_filters.DateTimeFromToRangeFilter()

    class Meta:
        model = ApiStatus
        fields = ['id', 'date_time']
        widgets = {
            'date_time': forms.DateTimeInput(attrs={'placeholder':'Select a date'})
        }

下图显示了没有日期选择器弹出窗口的手动文本输入。 enter image description here

这是我的模板文件，虽然我在尝试上述两种方法时没有改变它。 status_template.html

我确实在这里和其他地方研究过各种各样的资料。我尝试使用MultiWidget和jQuery，但没有得到那些工作。思考？提前致谢。

我能够使用没有外部依赖（没有jquery）解决它，只使用datetime-local输入和DateTimeFromToRangeFilter和Range小部件。也许不是最理想的解决方案，但这是一种方法。

我的模型，过滤器，视图和模板代码如下所示。

model.朋友

from app.modules.string_handler import StringHandler
from django.db.models.signals import post_save
import datetime

class ApiStatus(models.Model):
    id = models.AutoField(primary_key=True)
    date_time = models.DateTimeField("Date_Time", default=datetime.datetime.now(), blank=True)

    class Meta:
        managed = True
        db_table = 'api_status'
        verbose_name = 'API STATUS'

    def __str__(self):
        "A string representation of the model."
        return f'{self.id},{self.token},{self.date_time},{self.status},{self.summary},{self.log}'

    def __unicode__(self):
        return self.created_at

filter.朋友

from app.models.api_status import ApiStatus
import django_filters
from django import forms

class ApiStatusFilter(django_filters.FilterSet):

    date_time = django_filters.DateTimeFromToRangeFilter(
        lookup_expr=('icontains'),
        widget=django_filters.widgets.RangeWidget(
            attrs={'type':'datetime-local'}
        )
    )

    class Meta:
        model = ApiStatus
        fields = ['id', 'date_time']

    request.GET2 = request.GET.copy()

    if request.GET2.get('date_time_min'):
        request.GET2['date_time_min'] = datetime.strptime(request.GET2['date_time_min'],"%Y-%m-%dT%H:%M").strftime("%Y-%m-%d %H:%M")
    if request.GET2.get('date_time_max'):
        request.GET2['date_time_max'] = datetime.strptime(request.GET2['date_time_max'],"%Y-%m-%dT%H:%M").strftime("%Y-%m-%d %H:%M")

    apistatus_filter = ApiStatusFilter(request.GET2, queryset=apistatus_list)

    paginator = Paginator(apistatus_filter.qs, 10)
    page = request.GET.get('page')

    try:
        dataqs = paginator.page(page)
    except PageNotAnInteger:
        dataqs = paginator.page(1)

        dataqs = paginator.page(paginator.num_pages)

    return render(request, 'status_page_template.html', {'table_col_DATA':all_entries_ordered, 'dictionarys': dictionarys, 'apistatus_filter': apistatus_filter, 'dataqs': dataqs, 'allobjects': apistatus_list})
