Django - 按日期重新组合答案

【问题标题】：Django - Regroup By DateDjango - 按日期重新组合
【发布时间】：2017-06-15 20:13:31
【问题描述】：

我有一个包含以下字段的模型：“日期”、“员工”和“计划时间”。每个员工在不同日期都有不同的计划时间。

我正在尝试构建我的模板，其中员工按行列出，他们的计划工作时间在正确对应日期下的列中列出。

我目前正在按两个日期进行过滤。一名员工有第二个日期的时间，但没有最新的日期。我希望他的时间在第二个日期下正确列出，但目前它显示在当前日期下。大通看 1 小时：http://i.imgur.com/O4sake8.png

我的看法：

def DesignHubR(request):
emp3_list = Projectsummaryplannedhours.objects.values_list('displayval', 'employeename').\
filter(businessunit='a').filter(billinggroup__startswith='PLS - Project').filter(Q(displayval=sunday2)|Q(displayval=sunday)).\
annotate(plannedhours__sum=Sum('plannedhours'))
emp3 = map(lambda x: {'date': x[0], 'employee_name': x[1], 'planned_hours': x[2]}, emp3_list)
context = {'sunday': sunday, 'emp2': emp2, 'sunday2': sunday2, 'emp3': emp3}
return render(request,'department_hub_ple.html', context)

我的模板：

{% regroup emp3 by employee_name as emp9 %}
{% for employee_name in emp9 %}
<!--Job-->
<div class="table-row table-job-column employee-row">{{employee_name.grouper}}</div>
{% regroup employee_name.list by date|date as date_list %}
{% for y in date_list %}


<div class="table-row table-fr-column">{{y.list.0.planned_hours|default:"0"}}</div>
<div class="table-row table-fr-column">{{y.list.1.planned_hours|default:"0"}}</div>
{% endfor %}{% endfor %}

emp3_list 数据：

[{'date': 'W/E 6/18/17', 'planned_hours': Decimal('45.00000'), 'employee_name': 'Waylan'}, {'date': 'W/E 6/25/17', 'planned_hours': Decimal('45.00000'), 'employee_name': 'Waylan'}, {'date': 'W/E 6/18/17', 'planned_hours': Decimal('17.00000'), 'employee_name': 'Michael'}, {'date': 'W/E 6/25/17', 'planned_hours': Decimal('13.00000'), 'employee_name': 'Michael'}, {'date': 'W/E 6/25/17', 'planned_hours': Decimal('1.00000'), 'employee_name': 'Chase'}, {'date': 'W/E 6/18/17', 'planned_hours': Decimal('27.00000'), 'employee_name': 'Bert'}, {'date': 'W/E 6/25/17', 'planned_hours': Decimal('29.00000'), 'employee_name': 'Bert'}]

型号：

    number = models.CharField(db_column='Number', max_length=50, blank=True, null=True)  # Field name made lowercase.
    description = models.CharField(db_column='Description', max_length=100, blank=True, null=True)  # Field name made lowercase.

这可以是一个解决方案： {% for y in date_list %} 如果（y.list.0.date == current_date）{ {{y.list.0.planned_hours|默认值：“0”}} {{y.list.1.planned_hours|默认值：“0”}} {{y.list.2.planned_hours|默认值：“0”}} }别的{ ----- {{y.list.0.planned_hours|默认值：“0”}} {{y.list.1.planned_hours|默认值：“0”}} } {% endfor %}{% endfor %}
