Question

Say I have the models User and Project. Users and projects are HABTM-associated. My setup is actually a bit more complicated than this, but I think for the purposes of my question this will do.

Now, I want to use omniauth to authenticate a particular project with Twitter, Facebook, what have you. I’ve figured out how to define my omniauth path_prefix, but I don’t know how I could pass in a variable like so: config.path_prefix = 'projects/:project_id/auth', much less make a custom callback url like project/:project_id/auth/twitter/callback.

Answer 1

For posterity’s sake, I solved it this way:

I added an auth method to my projects controller, which set a session variable session[:auth_project_id] and then redirectes to auth/ + params[:provider].

In my callback controller authentications, I got my project with @project = Project.find(session[:auth_project_id]), created the authentication, and then session[:auth_project_id] = nil to unset the session variable.
