collective.excelexport
======================
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?excelexport.policy=excelexport.search&review_state=published 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
================
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; '
)
plone.restapi
=============
To get an export via rest api, query @collective.excelexport / @collective.excelexportcsv (with one @)
