Please, help me to implement the Ajaximage, it seems that is cant find the url, the file is stored in the proper folder, but the admin and the view cant find the image...

Project Setting:(does it need some django.contrib app??)

INSTALLED_APPS = (
....
'ajaximage',
.....

MEDIA_URL = 'media/'
MEDIA_ROOT = 'media/'

STATIC_URL = '/static/'
STATIC_ROOT = 'staticfiles'

AJAXIMAGE_DIR = 'media/'

STATICFILES_DIRS = (
os.path.join(BASE_DIR, 'static'),
)

Project URL:

urlpatterns = patterns('',
url(r'^ajaximage/', include('ajaximage.urls')),

urlpatterns = patterns('',
url(r'^$', views.index, name='index'),

Images App Admin:

from django.contrib import admin

from Images.models import Image
from ajaximage.fields import AjaxImageField

admin.site.register(Image)

Images App model:

from django.db import models

from ajaximage.fields import AjaxImageField

class Image(models.Model):
titulo = models.CharField(max_length=200)
data_publicacao = models.DateTimeField('date published')
thumbnail = AjaxImageField(upload_to='thumbnails',
max_height=200, #optional
max_width=200, # optional
crop=True) # optional
def unicode(self): # Python 3: def str(self):
return self.titulo
def was_published_recently(self):

contribute_to_class() takes exactly 3 arguments (4 given)

Hi when i syncdb i get error:

ajaximage\fields.py", line 34, in contribute_to_class
super(AjaxImageField, self).contribute_to_class(cls, name, virtual_only)
TypeError: Error when calling the metaclass bases
contribute_to_class() takes exactly 3 arguments (4 given)

then I remove virtual_only from 34 line and i get now error when I try save model:

"ajaximage\widgets.py in render, line 57"
"Error during template rendering
In template C:\Python27\lib\site-packages\django\contrib\admin\templates\admin\includes\fieldset.html, error at line 19"

If anyone have the same problem, please help me.. a try:

Replace (ajaximage\widgets.py in render, line 57):
file_url = value.url if value else ''
with:
file_url = value.url if value else str('')

I DO IT!!! But when i save model without name I get error about file_url = value.url if value else ''
I remove virtual_only=False and virtual_only from contribute_to_class in fields.py. THe results:
ajaximage\fields.py line 33- 35:

def contribute_to_class(self, cls, name):
super(AjaxImageField, self).contribute_to_class(cls, name)
setattr(cls, self.name, self.descriptor_class(self))

I try :
#12

How to validate the size?

Hi, I need to validate the size of the photo I'm uploading, how can I do it? Thank you.

Remove MEDIA_URL from filename

Thanks for the app, it's very handy, and works well on its own. The problem that I'm having is that when it saves the filename, it prepends the MEDIA_URL from settings, and always expects that to be included. This creates problems for other apps (e.g. sorl-thumbnail), which expect a path relative to MEDIA_URL, following the standard FileField behavior. It also creates problems if you were to switch between ImageField and AjaxImageField in an existing project (or change your MEDIA_URL).

I would suggest a boolean setting for prepending MEDIA_URL to the filename so as not to break existing projects (defaults to True). I can do a pull request for this if you agree with this solution.

HTTPResponse(json.dumps( doesn't work on Django 1.7

In ajaximage/views.py

return HttpResponse(json.dumps({'url': url, 'filename': path}))

should be changed to

from django.http import JsonResponse
return JsonResponse( {'url': url, 'filename': path} )

for Django 1.7+ This fixed my project.

ImageField attributes don't work

I am saying about width_field and height_field.
https://docs.djangoproject.com/en/1.9/ref/models/fields/#imagefield

Django 1.4 support

This line throws error with django 1.4
https://github.com/bradleyg/django-ajaximage/blob/master/ajaximage/fields.py#L34

This is resolved for example here: estuans@fbf9f33

by removing the 3rd parameter from call to super(AjaxImageField, self).contribute_to_class(cls, name, virtual_only)

If there is a way to do this so that it would support Django 1.4 -> 1.8 this would be nice!

Does not work with Grappelli

I'm not sure if it does work without Grappelli, but here are the errors I see in console when ajaximage-enabled fields are loaded:

Uncaught TypeError: Cannot call method 'ajaxTransport' of undefined jquery.iframe (transport.js:38)
Uncaught TypeError: Cannot read property 'cleanData' of undefined (jquery.ui.widget.js:24)
Uncaught TypeError: Cannot read property 'support' of undefined (jquery.fileupload.js:33)
Uncaught TypeError: Property '$' of object [object Object] is not a function (ajaximage.js:1)

The fields are completely gone, so there is not even graceful degradation.

upload_to should take callables

Like the Imagefield it replaces, upload_to could take a callable so that we can easily use directory names or filenames that contain the pk of the model.

Files are not removed on pressing 'Remove'

I've tried to upload an image three times and now there are three copies of it in the media folder.

Seems a shame not to also include a FileField

As I presume a lot of the code would be similar?

Ideally - the field could still display a thumbnail if the file was a recognised file format...

Can I use multiple AjaxImageWidget in a single page?

I want to use multiple widgets but when I pass more than one AjaxImageUploadForm into my template their input names have the same value ( ). I checked your widgets.py and tried to change the render method's name parameter but couldn't figure out where is this function called. Is there a way to do it or if my approach is not correct how can i use multiple forms?

CSRF issue django-cookiecutter

I have tried many times, with the general instruction. but I confuse with the example. it using django-ajaximage 29 but when I using pypi to install, it just take the 28 version. The problem is with that version it makes when I try to upload image through admin page, upload proccess just stuck on load file and terminal keeps warn about "CSRF token missing or incorrect". I don't know why, but I really appreciate if you can help me
