Pass in variable into presenter

[vinnyglennon]

Url: /api/v1/videos?auth_token=11112323432432

In controllors/api/v1/videos
I can easily get the user from the auth_token. I want to then make it available in the presenter, ideally via render :json => present("videos") { videos, :extra => user }

Is it possible to pass variables to presenter?
render :json => present("videos") { Widget.visible_to(current_user) } does not work in this case, as in the presenter, I want to show different information, depending on the user

I am currently storing the user_id in a thread in a controller:
Thread.current[:user_id] = 1

and accessing that in the presenter, but this is far less than ideal.

Hey @vinnyglennon. We expose current_user in our presenters with

module Api
  module V1
    module Helper
      def current_user
        ActiveRecord::Base.current_user
        # works in our user model, but you may need to put it on Thread.current.
      end
    end
  end
end

Brainstem::Presenter.helper(Api::V1::Helper)

I'm very open to discussion better methods.

Hi,
That's fine for getting current user. I don't want to do a devise type login and hence don't have access to current_user.

Instead, my idea is that a url has an auth_token. In the controller I find the correct user, and somehow pass it to the presenter. Exposing it to presenter is my issue. The helper will never have access to it, as its only in the controller.

Currently, is there any way to pass an object to presenter directly?

PS delighted to hear about V2 is in shunkworks, great piece of work!

That's a good point. I'll take a look at letting you pass objects through to presenters, unless you'd like to take a crack at it.

Hmmm, just noticed using Thread.current is causing rspec to fail, as rspec keeps referring to an older Thread.current. It does not look like a viable solution for this :(

I will work on getting some sort of solution for this into the next version of Brainstem.
