Question

我有一个图片栏

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <soapenv:Body>
      <ns1:GetActiveSuppliersResponse soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns1="http://webservice">
         <GetActiveSuppliersReturn soapenc:arrayType="ns2:webservice.supplierdto[3]" xsi:type="soapenc:Array" xmlns:ns2="http://DefaultNamespace" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">
            <GetActiveSuppliersReturn href="#id0"/>
            <GetActiveSuppliersReturn href="#id1"/>
            <GetActiveSuppliersReturn href="#id2"/>
         </GetActiveSuppliersReturn>
      </ns1:GetActiveSuppliersResponse>
      <multiRef id="id0" soapenc:root="0" soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xsi:type="ns3:webservice.supplierdto" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:ns3="http://DefaultNamespace">
         <asl_status xsi:type="xsd:string">Archived</asl_status>
         <zip xsi:type="xsd:string">11735</zip>
      </multiRef>
      <multiRef id="id2" soapenc:root="0" soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xsi:type="ns4:webservice.supplierdto" xmlns:ns4="http://DefaultNamespace" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">
         <asl_status xsi:type="xsd:string">Archived</asl_status>
         <zip xsi:type="xsd:string">92880</zip>
      </multiRef>
      <multiRef id="id1" soapenc:root="0" soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" xsi:type="ns5:webservice.supplierdto" xmlns:ns5="http://DefaultNamespace" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/">
         <asl_status xsi:type="xsd:string">Archived</asl_status>
         <zip xsi:type="xsd:string">91355</zip>
      </multiRef>
   </soapenv:Body>
</soapenv:Envelope>

并使用视图

    avatar = models.ImageField(upload_to="avatar", null=True, blank=True)

以模板形式

class EditView(SuccessMessageMixin, UpdateView):
model = MysiteUser
form_class = MysiteUserForm
pk_url_kwarg = 'pk'
template_name = 'update_form.html'
success_url = '/myprofile/'
success_message = "Zmiany zostały wprowadzone."

def form_valid(self, form):
    image_to_del = MysiteUser.objects.get(username=form.instance)
    print("Na dysku plik", image_to_del.avatar)
    print("Formularz i pole 'avatar'", form.instance.avatar)
    if form.instance.avatar != self.request.user.avatar:
        self.request.user.avatar.delete()
    return super().form_valid(form)

我想要更改链接，如下所示

<form action="" method="post" enctype="multipart/form-data">
    {% csrf_token %}
    {{ form.as_p }}
    <input type="submit" value="save" />
</form>

在图片上，我该怎么做？

覆盖ImageField中的url（）
