Sourcecode: bauble version File versions


#!/usr/bin/env python

# this script needs both a connections to a database created with bauble 0.6.x
# and the csv files exported from the same database, it will create a directory
# called 0.7 in the same directory as the exported csv files with the new
# converted files...you will also need the default geography data to have
# functioning database

# What has changed from 0.6->0.7 ?
# ------------------
# - species.id_qual column is now accession.id_qual column, any species
# specific id_qual data should be moved to the accessions with that species
# - accession.country_id is now accession.geography_id, try to find a match
# for the country_id if there is one in the geography table
# - species_meta is no more, this means that all the previous distribution data
# won't match up, it would be good if we could find a string match and add this
# to the new species_distribution table

# the columns we want to import

# TODO: how to use this script...export all tables from bauble first,

# This script will :
# 1. Create some CSV text files for importing into a Bauble 0.7
# database
# 2. Copy the rest of the CSV text files from a source directory into a
# destination that should also be imported into a new Bauble 0.7 database
# Basically this script will create a directory full of CSV files that
# can be imported into a Bauble 0.7 database.

# run this script and use the files it outputs in place of the ones from
