                           PostgreSQLStore

This is a PostgreSQL-based specialization of SQLStore.

To create an instance, see SQLStore.__init__. To create the tables it will use, see SQLStore.createTables.

All other methods are implementation details.

Instance Methods

db_set_assoc(self, server_url, handle, secret, issued, lifetime, assoc_type)
Set an association.

source code

blobEncode(self, blob)
Convert a str object into the necessary object for storing in the database as a blob.

Method Details

db_set_assoc(self, server_url, handle, secret, issued, lifetime, assoc_type)

source code

Set an association. This is implemented as a method because REPLACE INTO is not supported by PostgreSQL (and is not standard SQL).

blobEncode(self, blob)

source code

Convert a str object into the necessary object for storing in the database as a blob.

Overrides: SQLStore.blobEncode: (inherited documentation)
