Question

我不确定我是否进行了错误配置，但在我的表单中，datepickup小部件仅在一个字段上工作（t_start）。 t_end上的小部件无法正常工作。我不知道是什么导致了这个问题，也许有人在过去有类似的问题？

问题，如何在表单中选择名称与数据库中的id组合，此id添加到查询中的过滤器，例如sourcetype_id__in = [3]用变量列表替换（3）。

我的表格

from django import forms
from django.forms import ModelForm, DateField, DateInput
from platforms.models import Platforms, Sources

class TimeSelection(forms.Form):
    t_start = forms.DateField(widget=forms.DateInput(attrs={'id': 'datepicker'}))
    t_end = forms.DateField(widget=forms.DateInput(attrs={'id': 'datepicker'}))

class PlatformSelection(forms.Form):
    class Meta:
        model = Platforms
    platforms = forms.ModelMultipleChoiceField(queryset=Platforms.objects.all(), required=False)

class SourceSelection(forms.Form):
    class Meta:
        model = Sources
    sources = forms.ModelMultipleChoiceField(queryset=Sources.objects.filter(pk__in=[1, 3]), required=False)

视图

def queryset(request):
    t_start = None
    t_end = None
    platform = None
    source = None
    t_form = TimeSelection()
    p_form = PlatformSelection()
    s_form = SourceSelection()
    if request.method == "POST":
        t_form = TimeSelection(request.POST)
        p_form = PlatformSelection(request.POST)
        s_form = SourceSelection(request.POST)
        if t_form.is_valid() and p_form.is_valid() and s_form.is_valid():
            t_start = t_form.cleaned_data.get('t_start')
            t_end = t_form.cleaned_data.get('t_end')
            platform = p_form.cleaned_data.get('platforms')
            source = s_form.cleaned_data.get('sources')
    else:
        t_form = TimeSelection()
        p_form = PlatformSelection()
        s_form = SourceSelection()
    data = Events.objects.filter(platform_id__in=[7,8], sourcetype_id__in=[3], event_datetime__range=(t_start, t_end))
    return render_to_response('platforms.html', {'t_form': t_form,
                                                 'p_form': p_form,
                                                 's_form': s_form,
                                                 'data': data,
                                                 't_start': t_start,
                                                 'platform': platform,
                                                 'source': source,
                                                 't_end': t_end,
                                                 },
                              context_instance=RequestContext(request))

我的表单如下：

<form method="post" action="">{% csrf_token %}
  {{ p_form.as_table }}
  {{ s_form.as_table }}
  {{ t_form }}
  <input type="submit" value="Show Charts">  
 </form>

我最好的猜测是，对于日期输入窗口小部件id，您有相同的'id': 'datepicker'将其更改为不同的ID并且日期选择器应该有效。请记住DOM ids must be unique。
