ruby on rails - What happened to Mongoid.config.master.connection.host? -


i trying carrierwave (0.5.1) work mongoid (2.0.0.beta.20), rails 3. followed every step @ this guide.

in config/initializers/carrierwave.rb, have:

carrierwave.configure |config|   config.grid_fs_database = mongoid.database.name   config.grid_fs_host = mongoid.config.master.connection.host   config.storage = :grid_fs   config.grid_fs_access_url = "/uploads" end

when try start server (rails server). in console, get:

...config/initializers/carrierwave.rb:3:in `block in <top (required)>': undefined method `host' #<mongo::connection: 0x00000103802420> (nomethoderror)

i don't understand why getting error. i've looked everywhere , can't seem locate why happening...

it seems, mongoid.config.master.connection.host doesn't work anymore in newer versions of mongoid. removed? replacement this?

so far workaround following code:

carrierwave.configure |config|   config.grid_fs_database = mongoid.database.name   config.grid_fs_host = 'localhost'   config.storage = :grid_fs   config.grid_fs_access_url = "/uploads" end

line 3, should be: config.grid_fs_host = 'localhost'. <-- there better way dynamically indicate host depending on environment?

found out mongo gem has changed. has be:

config.grid_fs_host = mongoid.database.connection.primary_pool.host
