Datasources

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 = []
        fields.extend([get_exportable(
            field[1], self.context, self.request)
            for field in get_ordered_fields(action_fti)])
        fields.extend([get_exportable(
            ParentField(field[1]), self.context, self.request)
            for field in get_ordered_fields(oo_fti)])
        fields.extend([get_exportable(
            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.

Styles

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
              .interfaces.IThemeSpecific"
         factory=".excelstyles.MyNeutralStyle"
         provides="collective.excelexport.interfaces.IStyles"
          />

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; '
                         )
