• ul_content_field – Contenttype.field

  The uploaded file is included into the specific field from the specific Contenttype Example: File.file it uploads to field file from the contenttype File

Adding a custom File Mutator Utility

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.

<!-- An Utility to give images an "photo-" prefix -->
<utility component=".utility.prefix_image_filename"
         name="prefix-image-filename"/>

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)

Customization for specific BrowserLayer

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>

collective.uploadify Installation

To install collective.uploadify into the global Python environment (or a workingenv), using a traditional Zope 2 instance, you can do this:

• When you’re reading this you have probably already run easy_install collective.uploadify. Find out how to install setuptools (and EasyInstall) here: http://peak.telecommunity.com/DevCenter/EasyInstall

• If you are using Zope 2.9 (not 2.10), get pythonproducts and install it via:

  python setup.py install --home /path/to/instance

into your Zope instance.

• Create a file called collective.uploadify-configure.zcml in the /path/to/instance/etc/package-includes directory. The file should only contain this:

  <include package="collective.uploadify" />

Alternatively, if you are using zc.buildout and the plone.recipe.zope2instance recipe to manage your project, you can do this:

• Add collective.uploadify to the list of eggs and zcml to install, e.g.:

  [buildout]
  ...
  eggs =
      ...
      collective.uploadify
  
  zcml =
      ...
      collective.uploadify

• Re-run buildout, e.g. with:

  $ ./bin/buildout
