You can upgrade freely from v0.20 to v1.0.
|
|
|
|
However, if you're running a version < 0.20, upgrade to 0.20
|
|
before upgrading to 1.0.
|
|
|
|
The upgrade to 0.20 requires some minor code upgrades.
|
|
|
|
1. Note the exception changes in HISTORY. Certain exceptions are now scoped under the BSON
|
|
module; if you're catching these, you will need to modify your code.
|
|
|
|
2. The BSON types are now scoped under the BSON module.
|
|
|
|
3. Note that mongo_ext no longer exists. The new gems are bson and bson_ext.
|
|
|
|
4. Indexes on GridFS chunks collections should be unique. If you have existing GridFS
|
|
collections, you should drop the current index and replace with a unique one. Before you do this,
|
|
make sure that index doesn't exist; no need to go through process unnecessarily.
|
|
If you do need to create the index, once you have the chunks collection, here are the commands you can run:
|
|
|
|
@chunks.drop_index('files_id_1_n_1')
|
|
@chunks.create_index([['files_id', Mongo::ASCENDING], ['n', Mongo::ASCENDING]], :unique => true)
