    <p>I have following code in my models.py:</p> <pre><code>def product_upload_to(instance, filename): return 'img/products/%s/large/%s' % (instance.uuid, filename,) def thumb_upload_to(instance, filename): return 'img/products/%s/thumb/%s' % (instance.uuid, filename,) class Product(BaseModel): company = models.ForeignKey(Company, null=True, blank=True) title = models.CharField(max_length=128) description = models.TextField() category = models.ForeignKey(ProductCategory, null=True, blank=True) price = models.DecimalField(max_digits=5,decimal_places=2,verbose_name="Cena") image = models.ImageField(upload_to=product_upload_to,null=True,blank=True) thumb = models.ImageField(upload_to=thumb_upload_to,null=True,blank=True) def save(self, force_update=False, force_insert=False, thumb_size=(120,120)): image = Image.open(self.image) image.thumbnail(thumb_size, Image.ANTIALIAS) temp_handle = StringIO() image.save(temp_handle, 'png') temp_handle.seek(0) # rewind the file suf = SimpleUploadedFile(os.path.split(self.image.name)[-1], temp_handle.read(), content_type='image/png') self.thumb.save(suf.name+'.png', suf, save=False) super(Product, self).save(force_update, force_insert) </code></pre> <p>I ran into issues, which I'm not able to fix: - image path is generated properly for original image (image field) but not for the thumbnail (thumb field). </p> <p>It looks like:</p> <ul> <li>img/products/6fddb163-435b-11e3-98fe-843835614698/large/IMG_0171.JPG <strong>(good for image)</strong></li> <li>img/products/None/thumb/IMG_0171.JPG.png <strong>(bad for thumb)</strong></li> </ul> <p>Also, I am not sure if paths in admin panel are generated properly, because they are absolute (example: <code>http://localhost:8000/admin/app/product/1/img/products/6fddb163-435b-11e3-98fe-843835614698/large/IMG_0171.JPG</code>) - and I can't reach them. img directory is being created directly in django project directory, I don't know how to change this to be created within static directory.</p> <p>Could you help me to solve issue with thumb path and admin path?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
