为什么我得到这个值

如何解决为什么我得到这个值

我想当我点击用户释放按钮时，它会转到页面并自动获取所有用户信息。但我无法得到这个值。这是我点击的放电按钮中的图像，但显示如下。

这是我的代码：views.py

def discharge_view(request,pk):
form = DischargForm()
if request.method == 'POST':
    form = DischargForm(request.POST)
    if form.is_valid():
        form.save()
        messages.success(request,'Successfull')
        return redirect('discharge-patient')
context = {
    'form': form,}        

return render(request,'hospital/discharge.html',context)

forms.py :

class DischargForm(forms.ModelForm):
class Meta:
    model = PatientDischarge
    fields = ('assign_doctor','admitted','release_date','medicine_cost','other_charge')

    widgets = {
        'assign_doctor': forms.Select(attrs={'class': 'form-control'}),'admitted': forms.Select(attrs={'class': 'form-control'}),'release_date': forms.TextInput(attrs={'class': 'form-control'}),'medicine_cost': forms.TextInput(attrs={'class': 'form-control'}),'other_charge': forms.TextInput(attrs={'class': 'form-control'}),}

models.py

class PatientDischarge(models.Model):
assign_doctor = models.ForeignKey(Doctor,on_delete=models.CASCADE)
admitted = models.ForeignKey(Admitted,on_delete=models.CASCADE)
release_date = models.DateField(auto_now_add=False)
medicine_cost = models.IntegerField(null=True)
other_charge = models.IntegerField()

def __str__(self):
    return self.admitted.patient_name if all([self.admitted,self.admitted.patient_name]) else 0

def days_count(self):
    return self.release_date - self.admitted.admited_date if all([self.admitted,self.admitted.admited_date]) else 0

def room_bill(self):
    return self.days_count() * self.admitted.room_service if all([self.admitted,self.admitted.room_service])  else 0

def total_bill(self):
    return self.room_bill().days + self.medicine_cost + self.other_charge

放电.html

<form action="" method="POST" enctype="multipart/form-data">
                            {% csrf_token %}
                            {% for fields in form %}
                                <div class="form-group"></div>
                                {{ fields.label_tag }}
                                {{ fields }}
                            {% endfor %}
                            <br>
                            <input type="submit" value="Submit">

解决方法

要将实例传递给表单，您可以执行此操作 form = DischargForm(instance=<DischargeInstance>)，模板将根据实例在表单中预填充值。

你能提供你的models.py吗。
