Created April 21, 2013 18:19
Synchronize my PDF store of ebooks with my Papers2 SQLite3 database on my Mac. Replaces the title of each book with the filename on-disk, since I have my own naming convention that works much more nicely.
import sqlite3
import sys
conn = sqlite3.Connection("Database.papersdb")
query = "SELECT pub.ROWID, pdf.path, pub.title FROM Publication pub, PDF pdf WHERE pdf.object_id=pub.ROWID"
for row in conn.execute(query):
rowid, path, title = row
newtitle = path.replace("Files/", "").replace(".pdf", "")
sql = ('UPDATE Publication SET title=? WHERE ROWID=?', (newtitle, rowid))
print sql
conn.execute(*sql)
