The good thing about Devise/OmniAuth is its seamless integration with other API's (Twitter, Facebook, etc).

您可以尝试使用现有的gem来制作自己与Clearance的自定义集成.例如: https://github.com/nsanta/fbgraph (尽管尚未维护此gem等一下).仍然运作良好.

You could try to use existing gems to cook up your own custom integration with Clearance. For example: https://github.com/nsanta/fbgraph (Although this gem hasn't been maintained in a while). Still works well.
