If you want to so some special handling for uploaded files before they get created in the portal, you can simply register a new utility providing the IFileMutator Interface.
Your utility will be called with file_name, file_data, content_type just before the content will be created in the portal.
Parameters
file_name:
type: str
example: my-image.jpg
file_data:
type: <ZPublisher.HTTPRequest.FileUpload instance at -...>
can be used just like a file.
content_type:
type: str
example: 'image/jpeg'
A simple utility which adds a "photo-" prefix to image filenames
configure.zcml:
<!-- An Utility to give images an "photo-" prefix -->
<utility component=".utility.prefix_image_filename"
name="prefix-image-filename"/>
utility.py:
from zope import interface
def prefix_image_filename(file_name, file_data, content_type):
""" Prefix all images with 'photo-<filename>'
"""
# we only handle image files
if not content_type.startswith("image"):
return (file_name, file_data, content_type)
if not file_name.startswith("photo"):
file_name = "-".join(["photo", file_name])
return (file_name, file_data, content_type)
interface.directlyProvides(prefix_image_filename,
IFileMutator)
Note
Your utility has to return a tuple of:
(file_name, file_data, content_type)
If you have your own skin installed which is based on it's own BrowserLayer (by default IThemeSpecific) and want to customize the look and feel of collective.uploadify's you could override the upload view and/or the upload initialize callback view
Customize view template:
<configure xmlns="http://namespaces.zope.org/zope" xmlns:browser="http://namespaces.zope.org/browser"> ... <!-- Customize collective.uploadify upload template --> <browser:page for="collective.uploadify.browser.interfaces.IUploadingCapable" name="upload" template="templates/upload.pt" permission="cmf.AddPortalContent" layer=".interfaces.IThemeSpecific" /> </configure>
Customize initialize template:
from zope.i18n import translate from zope.component import getMultiAdapter from collective.uploadify.browser.upload import UploadInitalize from my.product import MyMessageFactory as _ class MyCustomUploadInitalize(UploadInitalize): """ Initialize uploadify js """ def upload_settings(self): portal_state = getMultiAdapter( (self.context, self.request), name="plone_portal_state") settings = super(MyCustomUploadInitalize, self).upload_settings() settings.update(dict( ul_height = 26, ul_width = 105, ul_button_text = translate(_('Choose images'), target_language= \ self.request.get('LANGUAGE', 'de')), ul_button_image = portal_state.navigation_root_url() + \ '/button_upload.png', )) return settings
Don't forget to register the new upload initialize view for your themespecific browserlayer by using:
<configure xmlns="http://namespaces.zope.org/zope" xmlns:browser="http://namespaces.zope.org/browser"> ... <browser:page for="*" name="upload_initialize" class=".uploadify.MyCustomUploadInitalize" permission="cmf.AddPortalContent" layer=".interfaces.IThemeSpecific" /> </configure>
