为什么我无法将记录保存到数据库？

Question

我有一个过去可以很好地工作的表格，但是在我更改了模型中的某些数据并添加了图像字段之后，它是行不通的。

从管理员我可以添加新记录，但是我认为表单ID有问题。

当我在Google Chrome浏览器中检查管理页面时，表单ID为porumbei_form     并且当我检查模板时，表单ID没有显示。

#My view 
@login_required(login_url='/login/')
def porumbelnou(request):
    if request.method == "POST":
        form = AdaugaPorumbel(request.POST, request.FILES)
        if form.is_valid():
            form.save()
            return HttpResponseRedirect('/porumbei/')
    else:
        form = AdaugaPorumbel()
    context = {
        'form': form,
    }
    template = loader.get_template("adaugare_porumbel.html")
    return HttpResponse(template.render(context, request))

#My form
class AdaugaPorumbel(forms.ModelForm):
    class Meta:
    model = Porumbei
    fields = ['data_adaugare', 'serie_inel', 'anul', 'culoare', 'crescator', 'culoare_ochi', 'sex', 'ecloziune',

    widgets = {
