圖像不從表單移除

我想在我的django應用程序中保存和過濾用戶的對象。輸入下面的代碼後，imagefield不會將任何圖像上傳到我的數據庫，也不會在我的模板中返回任何圖像。圖像不從表單移除

模型

class Fin(models.Model): 
    user=models.ForeignKey(User) 
    title=models.CharField(max_length=250, help_text='3 bedroom flat for lease') 
    main_view=models.ImageField(upload_to="photos",blank=True, null=True) 
    side_view=models.ImageField(upload_to="photos",blank=True, null=True) 
    address=models.CharField(max_length=200) 
    city=models.CharField(max_length=200) 
    state=models.CharField(max_length=200) 
    guideline=models.TextField(max_length=1000) 

    def __unicode__(self): 
     return self.title 


class FinForm(ModelForm): 
    class Meta: 
     model=Fin 
    fields=('title','main_view','side_view', 'address','city','state','guideline') 
    exclude=('user')

查看

 def fincrib(request): 
      extra_data_context={} 
      #if there's nothing in the field do nothing. 
      if request. method=="POST": 
      form =FinForm(request.POST) 
      if form.is_valid(): 
       data=form.cleaned_data 
       newfincribs=Fin(
        user= request.user, 
        title=data['title'], 
        main_view=data ['main_view'], 
        side_view=data['side_view'], 
        address=data['address'], 
        city=data['city'], 
        state=data['state'], 
        guideline=data['guideline']) 
       newfincribs.save() 
      extra_data_context.update({'FinForm':form}) 
     else: 
      form = FinForm() 
      extra_data_context.update({'FinForm':form}) 
     extra_data_context.update({'Fins':Fin.objects.filter(user=request.user)}) 
     return render_to_response('post.html',extra_data_context,context_instance=RequestContext(request))

模板

 {% block content %} 
     <form action="." method="POST"> 
      {% csrf_token %} 
    <center> {{FinForm.as_p}} </center> 
     <input type="submit" value="Submit"/> 
     </form> 

     {% for Fin in Fins %} 
      <tr> 
      <a href="{% url profiles_edit_profile %}"> {{Fin.user}} </a> </p> </strong> 
      <p>{{Fin.title}}</p> 
      <p><img src="{{MEDIA_URL}}/{{Fin.main_view}}"/></p>
