Hi I am learning how to use omniauth as backend for ember app.
when i run my application I get the below mentioned erroe OmniAuth::NoSessionError - You must provide a session to use OmniAuth
on resue rails s my applicataion halts at line below.
172: def call!(env) # rubocop:disable CyclomaticComplexity
173: unless env['rack.session']
174: error = OmniAuth::NoSessionError.new('You must provide a session to use OmniAuth.')
=> 175: fail(error)
176: end

It is because you disabled the session middleware (look at the output of rake middleware
). Omniauth will not work without the session middleware.
You disabled it here: Rails.application.config.session_store :disabled
If you are trying to ditch session because you do not use it other than for Omniauth, then the only thing you can do is write your own middleware that injects ActionDispatch::Session::CookieStore
and possibly other necessary middlewares based on the URL (i.e. if the URL is /auth/*
). Here is an example of what I use to achieve this (only uses session if URL path is not /api/...
):
# /config/application.rb
config.middleware.insert_before ActionDispatch::ParamsParser, "SelectiveStack"
# /config/initializers/omniauth.rb
::OmniAuthConfig = Proc.new do
provider :github, # ...
end
# /app/middleware/selective_stack.rb
class SelectiveStack
def initialize(app)
@app = app
end
def call(env)
if env["PATH_INFO"].start_with?("/api/") # <--- Change URL path here
@app.call(env)
else
middleware_stack.build(@app).call(env)
end
end
private
def middleware_stack
@middleware_stack ||= begin
ActionDispatch::MiddlewareStack.new.tap do |middleware|
# needed for OmniAuth
middleware.use ActionDispatch::Cookies
middleware.use Rails.application.config.session_store, Rails.application.config.session_options
middleware.use OmniAuth::Builder, &OmniAuthConfig
# needed for Doorkeeper /oauth views
middleware.use ActionDispatch::Flash
end
end
end
end
In this example I only enable the session middleware when the URL does not start with /api/
. You will still need to remove Rails.application.config.session_store :disabled
and properly set up your session store, of course. In my example I use the cookie store. You might need to tweak my example based on which middleware you are missing in rake middleware
. But if you're not doing this for performance reasons then just reenable the session middleware.
Into application.rb
...
config.api_only = true
config.session_store :cookie_store, key: '_interslice_session'
config.middleware.use ActionDispatch::Cookies # Required for all session management
config.middleware.use ActionDispatch::Session::CookieStore, config.session_options
