该视图抛出AttributeError:“ PhotoForm”对象没有属性“ reservation”。会发生什么—函数通过,但实际上并未上传图像。在调试它时,该表格无效。
我尝试打印
形式保留
表格消息
形式照片
但这显示了这种追溯(这就是表单无效和未完成功能的原因。
当我从其他正在运行的功能中构建这个功能时,我有些困惑。谢谢您的帮助!
HTML表格
<form action="/photo/new/" method="post">{% csrf_token %}
<dl>
<dt>{{ form.reservation.label }}</dt>
<dd><select name="reservation"> {% for reservation in reservations %} <option value="{{reservation.id}}">{{reservation.date}} {{reservation.chef.cook.get_profile.firstname}} - {{reservation.guest.get_profile.firstname}}</option>{% endfor %}</select></dd>
<dt>{{ form.photo.label }}</dt>
<dd>{{ form.photo }}</dd>
<dt> {{ form.message.label }}</dt>
<dd>{{ form.message }}</dd>

表格:
class PhotoForm(forms.ModelForm):
class Meta:
model = Photo
fields = ('reservation','photo','message')

super(PhotoForm, self).__init__(*args, **kwargs)
该模型:

reservation = models.ForeignKey(Reservation)
message = models.CharField(default='',max_length=140)

最佳答案
不应使用表单(带有图像或文件字段)be initialized with request.FILES?
form = PhotoForm(request.POST, request.FILES)
