Django: add image in an ImageField from image url

Today I had experience with django file downloads from an specified url into Django model FileField.
I'm writing content grabber from Flickr. I didn't find information about it and decided to write what I've discovered so far in example.

Stackoverflow helped me a bit. But answer proposed there had not worked.
So this is code example how to workout this issue:
because code worth a thousand words :)

We have a model with one field:
#models.py

class Photo(models.Model):
    image = models.ImageField('Label', upload_to='path/')

We need to create a photo from image url and save it to the model's FileField.

#somewhere in views.py

# usually in header imports
from urlparse import urlparse 
import urllib2 
from django.core.files import File
  #add imprt of content file wrapper
from django.core.files.base import ContentFile
# somewhere: for e.g. in view handling the file operations
photo
= Photo() img_url = 'http://i.ytimg.com/vi/GPpN5YUNDeI/default.jpg' name = urlparse(img_url).path.split('/')[-1]   #wrap your file content content = ContentFile(urllib2.urlopen(img_url).read())) photo.image.save(name, content, save=True)

In my project I used this in a bit another way.
First a user (site admin, for now) synchronizes with Flickr. He downloads into django model all photos data for flickr "username".
Than all this synched photos appear in a view, where user can choose what photos to download into main app model.
Than it passes chosen list to next view. It parses synched model and actually downloads photos to main App.
Finally it cleans up temporary Flickr sync model.

Maybe that is an ugly and bad way to do this. My excuses are to code less, because of using almost untouched plugin code. This feature, also, must be used 1 or 2 times in site production stage only.
So it is made for this purposes.

Maybe later I'll write an article on making Flickr content grabber for your Django site.
For now, thanks for reading and may The Code be with you!

Ideas, Suggestions? Please drop me a comment!

Time Capsule for $25

The real article name might be something like:  Configuring Raspbery Pi to serve like a Time Capsule with Netatalk 3.0 for Mountain Lion.  But it's too long ;) Here I will describe the process of using Raspberry Pi like a Time Machine in my network. To be able to backup your MAC's remotely (Like it would be NAS of some kind). It assumes you have a Raspberry Pi and have installed a Raspbian there and have a ssh connection, or somehow having access to it's console. Refer to my previous article for details . Now that we have a Pi that is ready for action let's animate it. So to make it suit you as a Time Capsule (NAS) for your MAC's you need to do those basic steps: - connect and configure USB hard drive(s) - install support of HFS+ filesystem to be able to use MAC's native filesystem - make mount (auto-mount on boot) of your hard drive - install Avahi and Netatalk demons - configure Netatalk daemon to make it all serve as a Time Machine - configure ...

Django: Resetting Passwords (with internal tools)

I have had a task recently. It was about adding a forms/mechanism for resetting a password in our Django based project. We have had our own registration system ongoing... It's a corporate sector project. So you can not go and register yourself. Admins (probably via LDAP sync) will register your email/login in system. So you have to go there and only set yourself a password. For security reasons you can not register. One word. First I've tried to find standart decision. From reviewed by me were: django-registration and django password-reset . These are nice tools to install and give it a go. But I've needed a more complex decision. And the idea was that own bicycle is always better. So I've thought of django admin and that it has all the things you need to do this yourself in no time. (Actually it's django.contrib.auth part of django, but used out of the box in Admin UI) You can find views you need for this in there. they are: password_reset password_reset_...

Django: Beautiful multiple files Upload Plugin using jQuery UI.

After successful developing python back-end for Sebastian Tschan jQuey Plugin  I've decided to make a reusable app for that purpose. So: This is a plugin, made using multiupload form from Sebastian Tschan. It uses jQuey UI and jQuery instead of Flash uploader. On Django side it uses sorl-thumbnails and PIL. You can use it in your applications with simple inclusion tag jQuery Features it has: Multiple file upload: Allows to select multiple files at once and upload them simultaneously. Drag & Drop support: Allows to upload files by dragging them from your desktop or filemanager and dropping them on your browser window. Upload progress bar: Shows a progress bar indicating the upload progress for individual files and for all uploads combined. Cancelable uploads: Individual file uploads can be canceled to stop the upload progress. Resumable uploads: Aborted uploads can be resumed wi...
