Couchbase lite rename database

Question

How can I rename an existing couchbase lite database (I'd like to avoid creating a new db and having to copy the contents over if possible). Is this the same as replicate to a database locally that has the same name?

Since you map your local database to a remote couchbase bucket using the CBLReplication classes, I can't see any reason why renaming the database shouldn't work.

Just make sure you close your CBLDatabase first:

database.close()

And use the NSFileManager to move the database mydb.cblite from within the CBLManager.sharedInstance().directory as you like:

let databaseManager = CBLManager.sharedInstance()
let fileManager = NSFileManager.defaultManager()
let sourceName = "\(database.name).cblite"
let targetName = "my-new-name.cblite"
if let sourcePath = NSURL(databaseManager.directory,isDirectory:true).URLbyAppendingURLComponent(sourceName).path,
let targetPath = NSURL(databaseManager.directory,isDirectory:true).URLbyAppendingURLComponent(targetName).path{
  fileManager.moveItemAtPath(sourcePath,atPath: targetPath)
}

And afterwards reopen the connection to the database with the same CBLReplication settings as before:

let database = databaseManager.databaseNamed("my-new-name")

Please keep in mind you might also move the mydb attachments directory first. And after reopening the connection making sure all of your code is using the new reference for querying etc.

PS: The code used here is written from memory, so it may not work copied 1:1 - but you should get the idea.
