python - Django - 将日期设置为日期输入值

Question

我正在尝试将日期设置为表单中输入日期的值。但是，正如您可能已经猜到的那样，它不起作用。

这是我的模板中的内容:

<div class="form-group">
       <label for="date" class="col-md-3 control-label">Date</label>
    <div class="col-md-9">
        <input type="date" class="form-control" id="date" value="{{placement.date}}">
    </div>
</div>

这是调用它的 View 以及 Placement 模型:

class Placement(models.Model):
    student = models.ForeignKey(Student)
    email = models.EmailField(max_length=254)
    fname = models.CharField(max_length=50)
    sname = models.CharField(max_length=50)
    cname = models.CharField(max_length=100)
    position = models.CharField(max_length=50)
    house = models.CharField(max_length=50, blank=True)
    street = models.CharField(max_length=50)
    town = models.CharField(max_length=50)
    county = models.CharField(max_length=50)
    postcode = models.CharField(max_length=8)
    phone = models.CharField(max_length=20)
    length = models.IntegerField(null=True)
    category = models.CharField(max_length=50)
    date = models.DateField(null=True)
    confirmed = models.BooleanField(default=False)
    completed = models.BooleanField(default=False)
    created = models.DateTimeField(null=True)

def view_placement(request, placement_id):
    school = School.objects.get(pk=request.session['school'])
    context = {'school':school}
    if request.session['utype'] == 'a':
        context['user'] = Administrator.objects.get(pk=request.session['user'])
        context['placement'] = Placement.objects.get(pk=placement_id)
        return render(request, 'workxp/admin/view_placement.html', context)

但它不显示日期。只是一个空的日期输入...

我该如何解决这个问题？

谢谢!

HTML 日期应采用 YYYY-MM-DD 格式。因此，您必须使用 {{ value|date:"D d M Y"}} 命令进行转换。

您的代码将是:

 <input type="date" class="form-control" id="date" value="{{placement.date|date:"Y-m-d" }}">
