Question

models.py

class Employee(models.Model):
    name = models.CharField(max_length=100)
    company = models.ForeignKey(Company, null=True, on_delete=models.SET_NULL, related_name='company')

views.py

class Employee(CreateView):
    fields = ('name','company')
    model = models.Employee

    def form_valid(self, form):
        self.object = form.save(commit=False)
        comp_name = self.request.POST.get("company", "")
        shop_id = ""            

        for word in dept_name.split(" "):
            shop_id += word[:1]

        self.object.nik = shop_id[-3:]
        self.object.save()

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

iam尝试从我的代码self.request.POST.get("company", "")获取ForeignKey的值是公司的返回id，我需要返回company.name。怎么做？...

Answer 1

你不应该访问request.POST;表单的重点是它将发布的数据转换为正确的格式，在本例中为ForeignKey。

此处，由于form.save，公司已存储在对象上;你应该在那里访问它：

    self.object = form.save(commit=False)
    comp_name = self.object.company.name

django将ForeignKey表示为ForeignKey.name而不是ForeignKey.id
