动态增值不保存到数据库中。仅保存我们第一次给出的值。并且额外添加的数据没有保存到数据库中。

Answer 1

Models.py:

class ordernewmodel(models.Model):   
    process_name = models.CharField(max_length=100)
    machine = models.CharField(max_length=100)
    add_info = models.CharField(max_length=100, unique=True)


forms.py:

class ordernewform(forms.ModelForm):
    class Meta:
        model = ordernewmodel
        fields = "__all__"




Views.py:


def ordernewview(request):
    if request.method == 'POST':
       
        if request.POST.get('process_name ') and  request.POST.get('machine') and request.POST.get('add_info')) :
            ordsave = ordernewmodel()          
            ordsave.process_name= request.POST.get('process_name')
            ordsave.machine= request.POST.get('machine')
            ordsave.add_info= request.POST.get('add_info')
            cursor = connection.cursor()
            cursor.execute("call orderordernew('"ordsave.process_name"' +'"ordsave.machine"' +'"ordsave.qty"' )")
            return render(request, 'my-order.html')
        else:
            print("nothing has to be print")
            return render(request, 'ordernew.html')
