ActionDispatch::Session::ActiveRecordStore failed to save session

[camiloabrilth1999]

Hi, I'm doing my own implementation of the session class, logically using this gem to save the sessions in a database.

Although I am aware that the data attribute contains the reference to the user, I customized my session model to add a field called user_id, being referenced in the database.

The problem is with the association in rail models, placing the line belongs_to :user will cause the following error:

   (0.4ms) BEGIN
  ↳ /.rbenv/versions/2.6.3/lib/ruby/gems/2.6.0/gems/activerecord-5.2.4.1/lib/active_record/log_subscriber.rb:98
   (0.3ms) ROLLBACK
  ↳ /.rbenv/versions/2.6.3/lib/ruby/gems/2.6.0/gems/activerecord-5.2.4.1/lib/active_record/log_subscriber.rb:98
Warning! ActionDispatch::Session::ActiveRecordStore failed to save session. Content dropped.


ActionController::InvalidAuthenticityToken - ActionController::InvalidAuthenticityToken:
  appsignal (2.10.0) lib/appsignal/rack/rails_instrumentation.rb:19:in 'call

I would like to know if anyone knows how to fix it or if they have any correct implementation of the session model
