    <p>I am following a Django Tutorial where you are required to construct some image thumbnails once an image is saved in admin. I am also using Python's tempfile module to save a temporary file name.</p> <p>However I keep running into the following error:</p> <pre><code>"Type: IOError" "Value: [Errno 13] Permission denied: 'c:\\docume~1\\myname\\locals~1\\temp\\somefilename'" </code></pre> <p>Here is the code I am using</p> <p>Settings</p> <pre><code>MEDIA_ROOT = '/home/myname/projectname/media/' MEDIA_URL = 'http://127.0.0.1:8000/media/'enter code here </code></pre> <p>models.py</p> <pre><code>from string import join import os from PIL import Image as PImage from settings import MEDIA_ROOT from os.path import join as pjoin from tempfile import * from string import join from django.db import models from django.contrib.auth.models import User from django.contrib import admin from django.core.files import File class Image(models.Model): title = models.CharField(max_length=60, blank=True, null=True) image = models.FileField(upload_to="images/") thumbnail = models.ImageField(upload_to="images/", blank=True, null=True) tags = models.ManyToManyField(Tag, blank=True) albums = models.ManyToManyField(Album, blank=True) created = models.DateTimeField(auto_now_add=True) rating = models.IntegerField(default=50) width = models.IntegerField(blank=True, null=True) height = models.IntegerField(blank=True, null=True) user = models.ForeignKey(User, null=True, blank=True) thumbnail2 = models.ImageField(upload_to="images/", blank=True, null=True) def save(self, *args, **kwargs): #Save image dimensions super(Image, self).save(*args, **kwargs) im = PImage.open(pjoin(MEDIA_ROOT, self.image.name)) self.width, self.height = im.size # large thumbnail fn, ext = os.path.splitext(self.image.name) im.thumbnail((128,128), PImage.ANTIALIAS) thumb_fn = fn + "-thumb2" + ext tf2 = NamedTemporaryFile() im.save(tf2.name, "JPEG") self.thumbnail2.save(thumb_fn, File(open(tf2.name)), save=False) tf2.close() # small thumbnail im.thumbnail((40,40), PImage.ANTIALIAS) thumb_fn = fn + "-thumb" + ext tf = NamedTemporaryFile() im.save(tf.name, "JPEG") self.thumbnail.save(thumb_fn, File(open(tf.name)), save=False) tf.close() super(Image, self).save(*args, **kwargs) def size(self): """Image size.""" return "%s x %s" % (self.width, self.height) def __unicode__(self): return self.image.name def tags_(self): lst = [x[1] for x in self.tags.values_list()] return str(join(lst, ', ')) def albums_(self): lst = [x[1] for x in self.albums.values_list()] return str(join(lst, ', ')) def thumbnail_(self): return """&lt;a href="/media/%s"&gt;&lt;img border="0" alt="" src="/media/%s" /&gt;&lt;/a&gt;""" % ( (self.image.name, self.thumbnail.name)) thumbnail.allow_tags = Trueenter code here </code></pre> <h1>ADMIN</h1> <pre><code>class ImageAdmin(admin.ModelAdmin): # search_fields = ["title"] list_display = ["__unicode__", "title", "user", "rating", "size", "tags_","albums_", "thumbnail", "created"] list_filter = ["tags", "albums", "user"] def save_model(self, request, obj, form, change): obj.user = request.user obj.save() </code></pre> <p>I know there are much more effective ways of using image thumbnails in Django however I would like to know why I keep getting this Permission error when thumbnails are used in this manner.</p> <p>All help is greatly appreciated.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
