Rails Time Travel

Time travel with timecop for your Rails app (in development, staging or other env).

Very often you need to create objects or other things in the "past". With thins gem and excellent timecop gem you can freeze time to any date/time.

For developers & QA's.

Open /rails/time_travel to see

Now you can adjust the datetime. Once you are done - just reset time (you will see a red button).

Note, that this datetime change is related only to your session.

Add this line to your application's Gemfile:

group :development do
  gem 'rails_time_travel' # you can also use it on staging env or production
end

• this approach has all limitation which timecop has. In addition it won't work on your background jobs or SQL's with NOW(), because this gem doesn't change system time and background job is a separate process.
• selected datetime is static, it means that value is freezed, if you need to change it you need to reset or adjust it with buttons

• BUNDLE_GEMFILE=gemfiles/rails_6_1.gemfile bundle exec rake test to run for Rails 6.1
• BUNDLE_GEMFILE=gemfiles/rails_6_0.gemfile bundle exec rake test to run for Rails 6.0
• BUNDLE_GEMFILE=gemfiles/rails_5_2.gemfile bundle exec rake test to run for Rails 5.2

• jump to a specific datetime with datetime picker?
• CI for Rails 4.X
• protect with password (for example how I did in rails_performance gem)
• go the the future?
• make datetime not static? (use lambda)
