Question

此问题与this有关。

我打算从表单字段中保存值。下面是我的循环代码代码：

def form_valid(self, form):
        tooth = [18, 17, 16, 15, 14, 13, 12, 11, 21, 22, 23, 24, 25, 26, 27, 28, 48, 47, 46, 45, 44, 43, 42, 41, 31, 32, 33, 34, 35, 36, 37, 38]
        tooth.reverse()
        mytooth = {}
        pt = self.kwargs['pk']

        for t in tooth:
            mytooth = self.request.POST.getlist('tooth_' + str(t), [])
            mytooth = " ".join(mytooth)
            form.instance.status = mytooth
            form.instance.position = t
            form.instance.patient = PatientInfo.objects.get(pk=pt)
        return super(DentalRecordCreateView, self).form_valid(form)

问题在于我可以使用

查看值

show = str(t) + mytooth
messages.success(self.request, show)  # display values

但只有字段form.instance.patient在我的数据库中有值。我在这里缺少什么？

我认为您错过了for循环中的form.save()。这至少可以解释为什么数据库中没有数据。它应该看起来像：

def form_valid(self, form):
        tooth = [...]
        tooth.reverse()
        mytooth = {}
        pt = self.kwargs['pk']

        for t in tooth:
            mytooth = self.request.POST.getlist('tooth_' + str(t), [])
            mytooth = " ".join(mytooth)
            form.instance.status = me
            form.instance.position = t
            form.instance.patient = PatientInfo.objects.get(pk=pt)
            form.save()

        return super(DentalRecordCreateView, self).form_valid(form)

将django表单保存在for循环中
