timetable_choices =(
('Monday','Monday'),
('Tuesday','Tuesday'),
('Wednesday','Wednesday'),
('Thursday','Thursday'),
('Friday','Friday'),
('Saturday','Saturday'),
)
class Timetable(models.Model):
day = models.ForeignKey('Day',on_delete=models.CASCADE,blank=True,null=True)
start = models.IntegerField()
end = models.IntegerField()
subject = models.CharField(max_length=12)
class Day(models.Model):
day = models.CharField(max_length=9, choices=timetable_choices)
我已经填充了Day表和Timetable表。
class Timetabletemplate(TemplateView):
template_name = 'timetable.html'
def get_context_data(self, **kwargs):
context = super().get_context_data(**kwargs)
context['timetable'] = Timetable.objects.all()
context['monday'] = Timetable.objects.filter(day="Monday")
return context
<table style="width:100%">
<tr>
<th></th>
<th>1</th>
</tr>
<tr>
<td>Monday</td>
{% for item in monday %}
<td>{{item.subject}}</td>
{% endfor %}
</tr>
</table>
我想做的是渲染单元格中的主题。我有n个主题,主题的数量取决于用户添加了多少个主题。我希望第一行中的day = Monday时的主题,而星期一以下各行中的day = Tuesday,wednesday时的主题相似。
尝试此代码时出现错误
invalid literal for int() with base 10: 'Monday'
。
答案 0 :(得分:3)
context['monday'] = Timetable.objects.filter(day__day="Monday")
在使用ForeignKey
到Day
模型时,日期另存为pk
,而不是选项名称
