====================
django-image-cropper
====================
This application is used for image cropping. User can upload some images or photo,
pick wished area up and save image.
The license is MIT.
Requirements
============
Starting with version 0.2 the Django of version 1.3+ is required. If you're
use an older Django version, please
Also you need PIL or Pillow graphic libraries to be installed. The PIL
will be installed together with django-image-cropper
Installation
============
First of all, please install django-image-cropper:
::
pip install django-image-cropper
Then you must edit your settings module: add item 'cropper' to
your INSTALLED_APPS:
::
INSTALLED_APPS += (
'cropper',
)
Next step add django-image-cropper URL config to your url module:
::
urlpatterns = patterns('',
....
url('^cropper/', include('cropper.urls')),
...
)
And last call syncdb management command in your project:
::
./manage.py syncdb
if you're use django.contrib.staticfiles application, you also
need to collect static files:
::
./manage.py collecstatic
Otherwise you need copy django-image-cropper/cropper/static files into your
STATIC_ROOT directory manually or create a symlink.
Usage
=====
Open /cropper/ URL in your browser. Here you can choose image via file input
and upload it. On the next screen, if javascript is enabled and static serves
good, you'll see the jQuery's jCrop plugin workspace. Pick some area and push
the Crop button to get cropped image
Cropped image copies are saved on server
Customize crop logics
=====================
Of course, default logic is poor and unusable. But you can easy change
application behavior.
You can write own success handlers for image upload and image crop and tell
django to use it.
To use own hanlders insead of defaults, just use own URLConfs. You must use
own 'success' key in keyword args. This value must be python callable type
::
from cropper.forms import CroppedForm, UploadForm
from my_project.utils import my_upload_handler, my_crop_handler
urlpatterns = patterns('cropper.views',
url('^$', view='upload', name='cropper_upload', kwargs={'form_class': UploadForm, 'success': my_upload_handler}),
url('^(?P<original_id>\d+)/$', view='crop', name='cropper_crop', kwargs={'form_class': CropForm, 'success': my_crop_handler}),
)
As you see, you can also use another form class instead of standart if you'll
specify 'form_class' key, but probably don't need this.
What handler is it?
Each handler is python function which has some input arguments and returns
HttpResponse object like every view function.
Let's see to upload handler prototype:
::
def my_upload_success_handler(request, form, original):
"""
Success upload handler
"""
print "Uploda form data", form.cleaned_data
print "File uploaded to " % original.image.path
# This handler do nothing, but print parameters
from django.shortcuts import redirect
return redirect(original)
* **request** is WSGIRequest object (same as view)
* **form** is upload form instance. This form instance is valid anyway.
* **original** is Original model instance. Image field calls ``image``
Crop handler prototype:
::
def my_crop_success_handler(request, form, original, cropped):
"""
Custom crop handler
"""
print "Crop form data", form.cleaned_data
print "Original object: %s" % original
print "Original in cropped model (the same in previous line): %s" % cropped.original
print "Cropped image: %s" % cropped.image
# For example, we can use cropped image as user profile avatar
# Perhaps user is authenticated and skip checks ;)
from django.core.files.base import ContentFile
from django.contrib import messages
from django.shortcuts import redirect
import os
profile = request.user.get_profile()
profile.avatar.save(
os.path.basename(cropped.image.path),
ContentFile(cropped.image.path)
)
messages.success(request, 'Avatar uploaded and cropped')
return redirect(request.user)
First three arguments the same as upload handler input arguments. Fouth - is
**Cropped** model instance. It has ``image`` field containts cropped image and
foreign key to related Original photo.
