2==========================
3
4quintagroup.catalogupdater package is intended for extending ZCatalog API
5with possiblity to update selected columns only. This package registers
6'catalog_updater' utility for that.
7
8To simplify usage of the utility, quintagroup.catalogupdater extends GenericSetup's
9ZCatalog XMLAdapter handler, which allows to *update* attribute usage in *column*
10tag of *catalog.xml* file.
11
12So, when you add a new column to the catalog, you add catalog.xml file
13in some profile with following part::
14
15 ...
16 <column value="new_column" />
17 ...
18
19This adds *new_column* metadata to the portal_catalog, BUT, this
20metadata will be empty untill you rebuild the catalog. To automate
21this step you can add 'update="True"' attribute to the tag. And this
22will lead to column update after adding. Thus, result usage should look
23like this::
24
25 ...
26 <column value="new_column" update="True" />
27 ...
28
29It also supports subtransactions, based on threshold property of ZCatalog.
