[djapian-users] Exception Type: DatabaseLockError. Please help!

[jul]

Hi,

I've got the exception shown below when executing indexer.update(). I
have no idea about what to do: it used to work and now index database
seems "locked".

Anybody can help?

Thanks

Hi, jul!

Xapian can handle only one writer to its database at once. So you don't have to call `index.update()` from your views. Use `manage.py index` command with scheduler to update index.
