Fixing Knowclip .apkg files: one more thing
(N.B. A much-improved version of this script is published in a later post)
Fixing the Knowclip note files as I described previously, it turns out, is only half of the fix with the broken .apkg files. You also need to fix the cards table. Why? Same reason. The rows are number sequentially from 1. But since Anki uses the card id field as the date added, the added field is always wrong. Again, the fix is simple:
#!/usr/bin/env python3
import sqlite3
import time
import datetime
db_path = '/path/to/knowclip/generated/apkg/collection.anki2'
conn = sqlite3.connect(db_path)
cursor = conn.cursor()
q = 'UPDATE cards SET id = nid + 10'
cursor.execute(q)
conn.commit()
conn.close()Here’s an improved version of the previous script, one that incorporates changes to both the notes and the cards tables.
#!/usr/bin/env python3
import sqlite3
import time
import datetime
# start date for new cards
dt = input("Creation date 2021-04-05: ")
(year,month,day) = [int(x) for x in dt.split('-')]
tm = input("Creation time 05:00: ")
(hr, minute) = [int(x) for x in tm.split(':')]
new_date = datetime.datetime(year, month, day, hr, minute)
new_epoch = int(new_date.timestamp() * 1000)
print(f'Will begin create date with epoch ms {new_epoch}.')
db_path = '/path/to/knowclip/generated/apkg/collection.anki2'
conn = sqlite3.connect(db_path)
cursor = conn.cursor()
q = 'SELECT id FROM notes'
cursor.execute(q)
note_rows = cursor.fetchall()
note_chg_sql_cmds = []
for note_row in note_rows:
qn = f'UPDATE notes SET id = {new_epoch} WHERE id = {note_row[0]}'
note_chg_sql_cmds.append(qn)
qc = f'UPDATE cards SET nid = {new_epoch} WHERE nid = {note_row[0]}'
new_epoch = new_epoch + 100
cursor.execute(qc)
conn.commit()
qc = f'UPDATE cards SET id = nid +10'
cursor.execute(qc)
conn.commit()
for sql in note_chg_sql_cmds:
cursor.execute(sql)
conn.commit()
conn.close()
