Converting one Content Type into another

Description

It is possible to 'convert' one content type into another by extracting content from the source content type and adding it to the new content type.

Converting Pages into News Items

In this example we take a folder of Pages (meta type: Document) and create News Items from them: 

"""
from the News Item type, the new items will be content copies
of their corresponding Pages (Documents)"""

source_contenttype = 'Document'
target_contenttype = 'Service'

items = context.listFolderContents(
        contentFilter={"portal_type": source_contenttype})

for item in items:
    id = "%s-new" % item.getId()
    title = item.Title()
    description = item.Description()
    text = item.getText()

    service = context.invokeFactory(target_contenttype, id,
             title=title,description=description,text=text)

Todo

content type "Service"?

Converting Images into News Items

This is similar to the example of converting pages into news items. Notice that when we pass the image data to invokeFactory we need to make it into a string: 

source_contenttype = 'Image'
target_contenttype = 'News Item'

items = context.listFolderContents(
        contentFilter={"portal_type": source_contenttype})

for item in items:
    id = "%s-new" % item.getId()
    title = item.Title()
    imageCaption = text = description =  item.Description()
    image = str(item.getImage())

    service = context.invokeFactory(
            target_contenttype,
            id,
            title=title,
            description=description,
            imageCaption=imageCaption,
            text=text,
            image=image)
