Needed middlewares check broken app using redis session store

[PikachuEXE]

Just updated to rails_admin 1.4.2 and got this error on start up:

Required middlewares for RailsAdmin are not added
To fix tihs, add

  config.middleware.use ActionDispatch::Session::RedisStore, {:redis_server=>{:host=>"127.0.0.1", :port=>6379, :password=>nil, :namespace=>"spacious:development:sessions"}, :key=>"_spacious_development_sessions_v2017_01_04_1426"}

to config/application.rb.

instruction is followed, but error still appears

error raised from
https://github.com/sferik/rails_admin/blob/v1.4.2/lib/rails_admin/engine.rb#L46

related issue raised in redis-actionpack

Anyone?

[mshibuya]

Just pushed the fix, please let me know if it works.

@mshibuya I confirm the fix is working for my app. Thanks!

I am also experiencing same issue with Rails 6.0.0.rc1 and Rails_Admin 2.0.0.beta.

/var/lib/gems/2.5.0/gems/rails_admin-2.0.0.beta/lib/rails_admin/engine.rb:57:in `block in <class:Engine>': Required middlewares for RailsAdmin are not added (RuntimeError)
To fix this, add

  config.middleware.use ActionDispatch::Cookies
  config.middleware.use ActionDispatch::Flash
  config.middleware.use Rack::MethodOverride
  config.middleware.use ActionDispatch::Session::CookieStore, {:key=>"_pro_dejurebe_session"}

to config/application.rb.

[kaleemullah360]

adding following lines didn't resolved the issue.

  config.middleware.use ActionDispatch::Cookies
  config.middleware.use ActionDispatch::Flash
  config.middleware.use Rack::MethodOverride
  config.middleware.use ActionDispatch::Session::CookieStore, {:key=>"_pro_dejurebe_session"}

to config/application.rb

[mshibuya]

Can I take a look at your config/application.rb?

[kaleemullah360]

sorry for delay in reply, here is my application.rb file.

    config.api_only = true
    config.middleware.use ActionDispatch::Cookies
    config.middleware.use ActionDispatch::Flash
    config.middleware.use Rack::MethodOverride
    config.middleware.use ActionDispatch::Session::CookieStore, {:key=>"_pro_dejurebe_session"}
  end
end

Is this fixed with version 2.0?

[mshibuya]

Of course, still having this?

[okuramasafumi]

#3076 (comment)
It wasn't clear if this was resolved or not.
If Rails 6 and rails_admin 2 works well together, it's great!

[mshibuya]

Ah sorry I overlooked @kaleemullah360 's case 😨
I cloud not find anything suspicious in your code, can you paste full stack trace of the error?

[richardkmichael]

Update: I tested with tip of branch 1.x-stable (currently at 7528459) and it is fixed. Perhaps you can release 1.4.3 if is ready.

This seems to still be a problem.

Rails 5.2.4.1, rails_admin 1.4.2.

To fix tihs, add

  config.middleware.use ActionDispatch::Session::CookieStore, {:key=>"_test_app_session", :cookie_only=>true}

to config/application.rb.

☝️ can confirm that it's still an issue with rails 5.2.4.1 and rails_admin 1.4.2 but 1.x-stable fixes it just fine. Please release a new version.
