ActionDispatch::Cookies::CookieOverflow and Rails 4.1

Posted: June 3, 2014 | Author: | Filed under: daily learning | Tags: | Comments Off on ActionDispatch::Cookies::CookieOverflow and Rails 4.1

Ran into this error when adding a new route.

Turns out that I was stuffing the model.errors into the alert flash, making the session cookie relatively huge.

While stuffing all that data into the cookie wasn’t intended, it made me notice that we were storing the session in a cookie instead of a database like with other projects. It turns out that the ActiveRecord session store has been extracted out of Rails into its own gem recently, the details of which are available on the activerecord-session_store GitHub project page.

method_missing: undefined method `increment_open_transactions` database_cleaner

When using database_cleaner (0.9.1) with rails (4.1.0)

{my home path}/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/activerecord-4.1.0/lib/active_record/dynamic_matchers.rb:26:in `method_missing': undefined method `increment_open_transactions' for ActiveRecord::Base:Class (NoMethodError)
    from {my home path}/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/database_cleaner-0.9.1/lib/database_cleaner/active_record/transaction.rb:13:in `start'

    from {my home path}/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/database_cleaner-0.9.1/lib/database_cleaner/configuration.rb:75:in `block in start'
    from {my home path}/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/database_cleaner-0.9.1/lib/database_cleaner/configuration.rb:75:in `each'
    from {my home path}/.rbenv/versions/2.1.1/lib/ruby/gems/2.1.0/gems/database_cleaner-0.9.1/lib/database_cleaner/configuration.rb:75:in `start'

Somehow we were using an old version of database_cleaner,

gem "database_cleaner",   "~> 0.9.1"

because the fix was authored a year ago.

gem "database_cleaner", "~> 1.2.0"

I guess that will teach me to dig too deeply before simply trying the latest version of a gem.
