rails: Session options are nil. Unable to add sessions and automatic connection switching to an api_only app.

I recently updated sidekiq and I need to use sessions in my api_only rails app as per 6.2.1. I’ve tried to add them back in per the docs, but it doesn’t work. If I set config.api_only = true to config.api_only = false then it all works as expected. I opened an issue in the sidekiq repo and I was directed here.

Steps to reproduce

config/application.rb

    config.api_only = true

    # This also configures session_options for use below
    config.session_store :cookie_store, key: '_interslice_session'

    # Required for all session management (regardless of session_store)
    config.middleware.use ActionDispatch::Cookies
    config.middleware.use ActionDispatch::Session::CookieStore, key: '_interslice_session'
    config.middleware.insert_after(ActionDispatch::Cookies, ActionDispatch::Session::CookieStore, key: '_interslice_session')

    config.middleware.use config.session_store, config.session_options

Expected behavior

It should load the session cookie config?

Actual behavior

It looks like the sessions aren’t working and the web part of my app won’t boot.

I had the same issue using rails 6.0.6

For me, this issue was resolved by rearranging the middleware sequence. You can print your middleware sequence by running the rake middleware command. With the help of the command, you can check how the middleware is arranged with the config.api_only = false and how it is arranged with config.api_only = false. Then try to match the sequence with config.api_only = false as closely as possible.

This error appeared because the Cookies middleware was called too late in the stack. The solution was to move it a few places up the stack.

This code snippet worked for me (put it in the config/application.rb file):

config.api_only = true
if config.api_only
  config.session_store :cookie_store, key: '_interslice_session'
  config.middleware.insert_before Rack::Head, ActionDispatch::Session::CookieStore, config.session_options
  config.middleware.insert_before ActionDispatch::Session::CookieStore, ActionDispatch::Cookies
end

@rafaelfranca I found the issue.

I created a new rails api app rails new my_api --api --database=postgresql

These are the only changes I made.

I added session middleware and automatic database switching.

# This also configures session_options for use below
    config.session_store :cookie_store, key: '_interslice_session'

    # Required for all session management (regardless of session_store)
    config.middleware.use ActionDispatch::Cookies

    config.middleware.use config.session_store, config.session_options

    config.active_record.database_selector = { delay: 2.seconds }
    config.active_record.database_resolver = ActiveRecord::Middleware::DatabaseSelector::Resolver
    config.active_record.database_resolver_context = ActiveRecord::Middleware::DatabaseSelector::Resolver::Session

I get the same error

@Elgonzo422 before I updated sidekiq it didn’t require sessions.

This line config.middleware.use config.session_store, config.session_options prevents any of my web requests from succeeding, it doesn’t just fail on the sidekiq web ui but everyone of my routes. I only mention sidekiq because I need to use sessions to get the sidekiq web ui to work.

Just to be clear. I can remove sidekiq from my app all together and have the following as per the rails docs.

# This also configures session_options for use below
config.session_store :cookie_store, key: '_interslice_session'

# Required for all session management (regardless of session_store)
config.middleware.use ActionDispatch::Cookies

config.middleware.use config.session_store, config.session_options

Then I visit /v1/account/ within my api or even just run my rspec test for this endpoint and I get the error.
