Löschfunktion müssen Benutzer in UserEdit schreiben

Question

jeder bekam ich

models.py

.... 
class ProductsTbl(models.Model): 
    ..... 
    slug = models.SlugField(unique=True) 
    user = models.ForeignKey(User, blank=True, null=True) 
    useredit = models.CharField(max_length=32, blank=True, null=True) 
    image = models.ImageField(upload_to=get_imagep_Product, blank=True) 

    def __unicode__(self): 
     return self.name 
    def save(self, *args, **kwargs): 
     ''' On save, update timestamps ''' 

     if not self.id: 
      self.created = timezone.now() 

     return super(ProductsTbl, self).save(*args, **kwargs) 





def get_image_path(instance, filename): 
    return '/'.join(['thing_images', instance.thing.slug, filename]) 


class Upload(models.Model): 
    thing = models.ForeignKey(ProductsTbl, related_name="uploads") 
    image = models.ImageField(upload_to=get_image_path) #delete or upload image for this one 

    def save(self, *args, **kwargs): 
     super(Upload, self).save(*args, **kwargs) 
     if self.image: 
      image = Image.open(self.image) 
      i_width, i_height = image.size 
      max_size = (640,480) 

      if i_width > 1000: 
       image.thumbnail(max_size, Image.ANTIALIAS) 
       image.save(self.image.path) 

und ich bekam die views.py Funktion für das Bild löschen in der Klasse hochladen ist (models.Model) von models.py,

views.py

..... 
@login_required 
def delete_upload(request, id): 
# grab the image 

    upload = Upload.objects.get(id=id) 


    upload.thing.useredit = request.user.username 
    upload.save() 
# security check 
    # if upload.thing.user != request.user: 
    #  raise Http404 
# delete the image 
    upload.delete() 
# refresh the edit page 
    return redirect('edit_thing_uploads', slug=upload.thing.slug) 

, was ich tun muß, ist, wenn ich das Bild löschen Ich habe die „user“ in das „UserEdit“ zu schreiben.

jedoch ,, wenn ich nie das Bild löschen die "user" wird nicht in "UserEdit" schreiben ,, dagegen hier ist mein

edit_thing_uploads.html

{% extends 'base.html' %} 
{% block title %} 
Edit {{ thing.name }}'s Images - {{ block.super }} {% endblock %} 
{% block content %} 
<h1>Edit {{ thing.name }}'s Images</h1> 
<h2>Uploaded images</h2> 
{% for upload in uploads %} 
<img src="{{ upload.image.url }}" alt="" /> 
<a href="{% url 'delete_upload' id=upload.id %}">Delete</a> 
{% endfor %} 
<h2>Upload a new image</h2> 
<form role="form" action="" method="post" enctype="multipart/form-data"> 
{% csrf_token %} 
{{ form.as_p }} 
<input type="submit" value="Submit" /> 
</form> 
{% endblock %} 

wenn ich lade ein Bild wird es „user“ in „UserEdit“ erfolgreich ,, die Funktion zum hochladen Bild in

schreiben

views.py

@login_required 
def edit_thing_uploads(request, slug): 
# grab the object... 
    thing = ProductsTbl.objects.get(slug=slug) 
# double checking just for security 
    # if thing.user != request.user: 
    #  raise Http404 

    form_class = ProductsTblUploadForm 
# if we're coming to this view from a submitted form, 
    if request.method == 'POST': 
# grab the data from the submitted form, # note the new "files" part 
     form = form_class(data=request.POST,files=request.FILES, instance=thing) 
     if form.is_valid(): 
      thing = form.save(commit=False) 
      thing.useredit = request.user.username 
      thing.save() 
# create a new object from the submitted form 
      Upload.objects.create(
       image=form.cleaned_data['image'], 
       thing=thing, 
      ) 
      return redirect('edit_thing_uploads', slug=thing.slug) 
# otherwise just create the form 
    else: 
     form = form_class(instance=thing) 
# grab all the object's images 
    uploads = thing.uploads.all() 
# and render the template 
    return render(request, 'things/edit_thing_uploads.html', { 
     'thing': thing, 
     'form': form, 
     'uploads': uploads, 
    })
