Make all models not_sharded by default

[bogdan]

I am trying to make all my models not sharded by default with.

But it results in a weird behavior. on_shard call doesn't establish connection to shard because connection_specification_name calls is_sharded? on ActiveRecord::Base which is false.

The following code results in AR::ConnectionNotEstablished:

ActiveRecord::Base.not_sharded
class Visitor < ActiveRecord::Base
  self.sharded = true
end

ActiveRecord::Base.on_shard(1) do
 Visitor.first
end

While the following would work:

Visitor.on_shard(1) do
 Visitor.first
end

We have been trying to implement exactly that in the v4 branch: https://github.com/zendesk/active_record_shards/tree/v4

Development has stagnated a bit, but if you’re interested, please give it a try and let us know how it went.

I am also facing this annoyance with gems that create AR models that aren't sharded. It would be great to be able to reverse the behaviour. Possibly through a config option?

Nope, the necessary changes are too many to allow both options in the same library. I encourage you to experiment with the v4 beta versions. 😄
