Access Rails session from Faraday middleware

[evansj]

The README file has the following comment:

Her::API.setup :url => "https://api.example.com" do |builder|
  # This token could be stored in the client session
  builder.use MyAuthentication, :token => "..."
  # ...
end

Can you give me an example of how you could access the current Rails session from that code block? I've put the code in a Rails initialiser file.

Thanks

Well that's actually a bit more complicated than I thought (since you can only interact with the session in a controller, but here’s how I would do it. I haven’t tested it in Rails though, it’s just

See https://github.com/remiprev/her#authentication for a better example

Hope that helps!

I’m going to close this issue since it wasn’t active in the last month. Hopefully you found a solution that fit your needs!

@remiprev, just a quick question about the solution you provided. Is that thread safe? if the class MyApp is long lived and someone else comes in and sets the current_user before the FaradayMiddleware has access to it.. wouldn't that be bad? I ask because I don't know.

[remi]

Indeed, this is not thread safe. A better solution would be to use Thread.current (or something like this) to store the current user, like the audited gem does.

@incorvia I added a thread-safe example in README.md. I’m going to remove the non-thread-safe example above :)

Thank you @remiprev a very good example and a great resource for future use.
