collective.contentexport 1.0b2

Plone add-on to export dexterity content in various formats

collective.contentexport

Features

Exports dexterity content in various formats:

• xlsx

• xls

• csv

• tsv

• json

• yaml

• html (a table)

• zip-file containing all images from image-fields

• zip-file containing all files from file-fields

• zip-file containing related files and images from relationfields

Usage

Provides a form /@@export_view to configure the export.

The form allows you to:

• Select the export type

• Select the content type to export

• Choose fields from the selected type to be ignored

• Select the format of richtext-fields (html/plaintext)

• Select the format for files and images (url, base64, location within zip-file)

collective.contentexport uses tablib for several export-formats.

Use in code

You can use the export_view in code to have more control over the results.

The view export_view accepts the following parameters:

• export_type

• portal_type

• blob_format

• richtext_format

• blacklist

• whitelist

• additional

The following example creates a zip-file with images or files from the field primary_picture for the type some_type:

view = api.content.get_view('export_view', portal, request)
view(export_type='related', portal_type='some_type', whitelist='primary_picture')

You can also extend the export. In the following example the value some_fieldname is being extracted from the object using the method _somehandler.

def _somehandler(obj):
    return some_crazy_transform(obj.custom_field)

additional = {'some_fieldname': _somehandler}
view = api.content.get_view('export_view', portal, request)
result = view(export_type='json', portal_type='Document', additional=additional)

You can also override the default methods to modify the default behavior. In the following example the image from Images is being extracted using the method _get_imagename that only dumps the filename of the image:

def _get_imagename(obj):
    if obj.image:
        return obj.image.filename

additional = {'image': _get_imagename}
view = api.content.get_view('export_view', portal, request)
result = view(export_type='json', portal_type='Image', additional=additional)

collective.contentexport is tested to work in Plone 4 and Plone 5.
