Export dexterity contents in an excel file, one column by field

Project description


What does this product

This product provides tools to provide excel exports to Plone users, under xls or csv format.

A framework, with default utilities to export the dexterity contents of a folder, the results of a catalog search, and the results of a eea faceted navigation search. Many field types are managed (text, list, file, boolean, datagrid…).

Try @@collective.excelexport view on any folder containing dexterity elements. Try @@collective.excelexport? on site root.

Try @@collective.excelexportcsv view on any folder for csv export.

How to configure this product

You can set a list of fields to be excluded from export via the registry record: collective.excelexport.excluded_exportables

How to extend it


If you want to implement a new way to get content to export, you can register a #datasource#, wich is an adapter for collective.excelexport.interfaces.IDataSource interface.

This adapter can be a named one.

You will call this datasource calling the view @@collective.excelexport?excelexport.policy=datasourcename

See the IDataSource interface for more information

Exportables (excel sheet columns)

If you want to define new columns for your excel export, you will write or override:

- Exportable factories, adapters for IExportableFactory interface that provides a list of Exportables
- Exportables, that define columns.

Example of an exportable factory:

from plone.dexterity.interfaces import IDexterityFTI
from collective.excelexport.exportables.base import BaseExportableFactory
from collective.excelexport.exportables.dexterityfields import get_ordered_fields
from collective.excelexport.exportables.dexterityfields import get_exportable
from collective.excelexport.exportables.dexterityfields import ParentField
from collective.excelexport.exportables.dexterityfields import GrandParentField

class PSTActionFieldsFactory(BaseExportableFactory):
    adapts(IDexterityFTI, Interface, Interface)
    portal_types = ('pstaction',)

    def get_exportables(self):
        portal_types = api.portal.get_tool('portal_types')
        action_fti = portal_types['pstaction']
        oo_fti = portal_types['operationalobjective']
        os_fti = portal_types['strategicobjective']
        fields = []
            field[1], self.context, self.request)
            for field in get_ordered_fields(action_fti)])
            ParentField(field[1]), self.context, self.request)
            for field in get_ordered_fields(oo_fti)])
            GrandParentField(field[1]), self.context, self.request)
            for field in get_ordered_fields(os_fti)])
        return fields

Dexterity exportables

You have a complete set of exportables for dexterity fields. Those are multi-adapters of field, context and request.

You can override them declaring a more specific adapter.

You can also declare a named adapter with the field name if you want a specific rendering for one field.


If you don’t feel good with default styles, you can register a specific one for: ::
  • the export policy

  • the context

  • the layer

You just have to register a new IStyle adapter, in a zcml:

<adapter for="zope.interface.Interface

If you do not specify the name, the styles will be registered for all policies.

and in python:

class MyNeutralStyle(Styles):

    content = xlwt.easyxf('font: height 200, name Arial, colour_index black, bold off; '
                     'align: wrap off, vert centre, horiz left;'
                     'borders: top thin, bottom thin, left thin, right thin;'
                     'pattern: pattern solid, back_colour white, fore_colour white'

    headers = xlwt.easyxf('font: height 200, name Arial, colour_index black, bold on; '
                         'align: wrap off, vert centre, horiz left; '
                         'borders: top thin, bottom thin, left thin, right thin; '
                         'pattern: pattern solid, back_colour white, fore_colour white; '


To get an export via rest api, query @collective.excelexport / @collective.excelexportcsv (with one @)
