The data contained in tabular form in ZCatalogs is often exactly the data site admins frequently want to export into some other format, such as CSV. This package provides views for exporting the catalog data into various formats.

Currently, only exporting the whole catalog with all metadata/brains/columns as CSV is supported. I plan to add support for submiting arbitrary index queries and for controlling the metadata/brains/columns exported.

Start with a catalog with some indexes and metadata/brains/columns and a few objects indexed.

>>> self.folder.manage_addProduct['ZCatalog'].manage_addZCatalog(
...     'catalog', 'Catalog')
>>> catalog = self.folder.catalog
>>> catalog.addIndex('id', 'FieldIndex')
>>> catalog.addIndex('title', 'FieldIndex')
>>> catalog.indexes()
['id', 'title']
>>> catalog.addColumn('meta_type')
>>> catalog.addColumn('id')
>>> self.folder.manage_addProduct['OFSP'].manage_addDTMLDocument(
...     'foo_doc', 'Foo Document')
>>> catalog.catalog_object(self.folder.foo_doc)
>>> self.folder.manage_addProduct['OFSP'].manage_addDTMLDocument(
...     'bar_doc', 'Bar Document')
>>> catalog.catalog_object(self.folder.bar_doc)
>>> [(brain.meta_type, brain.id) for brain in catalog()]
[('DTML Document', 'foo_doc'), ('DTML Document', 'bar_doc')]

Open the export view in the browser specifying the export format as CSV.

>>> from Products.Five.testbrowser import Browser
>>> from Testing import ZopeTestCase
>>> self.setRoles(['Manager'])
>>> browser = Browser()
>>> browser.addHeader(
...     'Authorization', 'Basic %s:%s' %
...     (ZopeTestCase.user_name, ZopeTestCase.user_password))
>>> browser.handleErrors = False
>>> browser.open(catalog.absolute_url()+
...              '/export?Content-Type=text/csv')
>>> browser.isHtml
>>> print browser.headers
Status: 200 OK...
Content-Disposition: attachment...
Content-Type: text/csv...
>>> print browser.contents

XXX the testbrowser doesn't handle use of response.write(). I've verified that this works in a real browser:

System Message: WARNING/2 (<string>, line 68)

Literal block expected; none found.
