Question

我正在使用django作为框架来创建库存管理系统。我有一个简单的模型，其中包含product列和order_amount列。我希望用户能够使用modelformset更新的唯一部分是order_amount列。 Django会自动使用字段名称“订单金额”标记每个表单。我想要做的是将每个表单标记为要在“产品”字段中更新的实例。

models.py

class Sysco_Products(models.Model):
    Products = models.CharField(max_length = 200)
    order_amount = models.IntegerField(blank=True, null=True)

    def __str__(self):
        return self.Products

    class meta:
        managed = True
        db_table = 'sysco_products'

forms.py

from django import forms
from .models import Sysco_Products

class orderform(forms.ModelForm):

    class Meta:
        model = Sysco_Products
        fields = ('order_amount',)

views.py

class SyscoOrder(TemplateView):
        template_name= "SyscoOrder.html"

        def get(self, request):
                OrderFormSet = modelformset_factory(Sysco_Products, fields=('order_amount',))
                context = {
                        'OrderFormSet' : OrderFormSet,
                }
                return render(request, self.template_name, context)

        def post(self, request):
                OrderFormSet = modelformset_factory(Sysco_Products, fields=('order_amount',))
                formset = OrderFormSet(request.POST,)
                if formset.is_valid():
                        formset.save()
                        return redirect('Order')

                context ={
                        'formset' : formset,
                }
                return render(request, self.template_name, context)

您的意思是类似field.label = f"{sysco_product_instance.Products} amount:"吗？

这应该有效：

from django.utils.translation import gettext

class orderform(forms.ModelForm):

    class Meta:
        model = Sysco_Products
        fields = ('order_amount',)

    def __init__(self, *args, **kwargs):
        super(self, orderform).__init__(*args, **kwargs)
        if self.instance.Products.strip():
            self.fields['order_amount'].label = gettext("%(product_name)s amount:").format(product_name=self.instance.Products)

如何使用不同的字段作为modelformset的标签？
