django - Django 中的 UpdateView 不是从数据库的 datetimefield 加载时间，它是脆的形式吗？

问题描述

我有一个非常简单的表格：

class OnSiteLogForUserForm(forms.ModelForm):
  def __init__(self, *args, **kwargs):
    super(OnSiteLogForUserForm, self).__init__(*args, **kwargs)
    self.helper = FormHelper()  
    self.helper.form_class = 'form-horizontal'
    self.helper.label_class = 'col-lg-4'
    self.helper.field_class = 'col-lg-8'
    self.helper.add_input(Submit('submit', 'Submit'))


  class Meta:
    model=OnSiteLog

    fields = ('user', 'checkIn', 'checkOut', 'notes', 'location')

    widgets = {
     'checkIn':DateTimeInput(attrs={
          'class':'datepicker form-control',
          'id' : 'datetimepicker1',
          'tabindex' : '1',
          'placeholder' : 'MM/DD/YYYY hh:mm',          
          'autocomplete':'off',
      }, format='%m/%d/%Y'),
      'checkOut':DateTimeInput(attrs={
          'class':'datepicker form-control',
          'id' : 'datetimepicker2',
          'tabindex' : '2',
          'placeholder' : 'MM/DD/YYYY hh:mm',          
          'autocomplete':'off',
      }, format='%m/%d/%Y'),
      'location' : TextInput(attrs={'tabindex':'3', 'size': 40, 'placeholder':'Location'}),
      'notes' : Textarea(attrs={'tabindex':'4', 'placeholder':'Notes'}),
      
    }

在视图中单击编辑时加载

class LogUpdateView(UpdateView):                                                                                             

    model = OnSiteLog
    form_class = OnSiteLogForUserForm
    template_name = 'log/log_form.html'
    success_url = '/'
                                                                                         
    def get_context_data(self, **kwargs):
        context = super(LogUpdateView, self).get_context_data(**kwargs)
    
        log = context['object'] 
        context['log_id'] = log.id
        theLog = OnSiteLog.objects.get(pk=log.id)

    
        log_form = OnSiteLogForUserForm(instance=theLog)

        context['log_form'] = log_form 
    
        return context


    def post(self, request, *args, **kwargs):

        print("Posting...")

   
   
        super(LogUpdateView, self).post(request, *args, **kwargs)
        return HttpResponseRedirect(self.success_url) 

    def form_invalid(self, form):
        print("form is invalid")
        print(form.errors)
        return HttpResponse("form is invalid.. this is just an HttpResponse object")

但是当表单出现时，签入或结帐字段有日期但没有时间......现在当我创建它时，日期选择器可以很好地完成时间。也很有趣，它可以让您节省时间。

所以不知道为什么我的更新加载日期而不是时间，我什至将表单小部件更改为 DateTimeInput（它是 DateInput），但无济于事。

甚至不知道在哪里看这个，html 使用脆的形式：

{% extends "base.html" %}

{% load static %}

{% load crispy_forms_tags %}

                        j(this).ekkoLightbox();
                    });
