When I type
rake test
it doesn't do anything.
I have to test all files one by one by typing for example:
ruby -Itest test/models/post_test.rb
I created application with -T flag so it skipped tests. I recently added them manually though; maybe i forgot to add some file? idk;/
I had this exact problem and I found the issue was in my config/application.rb file.
Using -T caused this:
# Pick the frameworks you want:
require "active_model/railtie"
require "active_job/railtie"
require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "action_view/railtie"
require "sprockets/railtie"
# require "rails/test_unit/railtie"
I simply changed it to:
require "rails/all"
and my rake tasks work. You could also uncomment the commented test require, but requiring all seems easier and ensures I get any new libraries that may get added down the road.

I want to disable ActiveRecord in Rails 4. I did the following in config/application.rb
require File.expand_path('../boot', __FILE__)
# require 'rails/all' -- commented
require "action_controller/railtie"
require "action_mailer/railtie"
#require "active_resource/railtie" no need
#require "rails/test_unit/railtie" no need
#require "sprockets/railtie" no need
# Require the gems listed in Gemfile, including any gems
# you've limited to :test, :development, or :production.
Bundler.require(:default, Rails.env)
module MyApp
class Application < Rails::Application
config.app_middleware.delete "ActiveRecord::ConnectionAdapters::ConnectionManagement"
end
end
By I have an error of
/home/alex/.rvm/gems/ruby-2.0.0-p247/gems/railties-4.0.0/lib/rails/railtie/configuration.rb:95:in
method_missing: undefined method active_record for #<Rails::Application::Configuration:0x00000002005c38> (NoMethodError)
If you are creating a new application, you can use -O to skip ActiveRecord:
rails new my_app -O
For existing applications:
1. Remove database adapter gems from your Gemfile (mysql2, sqlite3, etc.)
2. Change your config/application.rb
Remove require 'rails/all line and require frameworks (among those available in your rails version, the list varies, do not just copy) you want to use, for example:
require "action_controller/railtie"
require "action_mailer/railtie"
require "sprockets/railtie"
require "rails/test_unit/railtie"
Remove config.active_record.raise_in_transactional_callbacks = true from config/application.rb
3. Delete your config/database.yml file, db/schema.rb and migrations (if any)
4. Delete migration check in test/test_helper.rb
5. Delete any ActiveRecord configuration from your config/environments files (this is what is causing your error)
This is all you need to do for an empty Rails app. If you run into problems caused by your existing code, stack trace should give you sufficient information on what you need to change. You might for example have some ActiveRecord configuration in your initializers.
Hi this is what the default rails new new_app -O gives
require "rails"
# Pick the frameworks you want:
require "active_model/railtie"
require "active_job/railtie"
# require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "action_view/railtie"
require "sprockets/railtie"
require "rails/test_unit/railtie"
inside your config/application.rb
Additionally, it comes without database.yml and NO db/migrate/* and schema.rb
Since this is still the first hit when searching Google for disabling active record for Rails 5, I'll add this here:
For Rails 5
Do all the steps in #mechanicalfish answer, but also remove the line
Rails.application.config.active_record.belongs_to_required_by_default = true
from
config/initializers/new_framework_defaults.rb
For those using the rails-api gem you may encounter a similar error when using the --skip-active-record flag when doing rails-api new my_api. The current fix (until a new corrected version of the gem is released) is to edit your rails-api gem to have this commit. Use bundle open and replace the old Gemfile with the new corrected one. Rerun and you should be all set.
For disable ActiveRecord in Rails 4.2 you may create config/initializers/middleware.rb
Rails.application.middleware.tap do |middleware|
middleware.delete ActiveRecord::Migration::CheckPending
middleware.delete ActiveRecord::ConnectionAdapters::ConnectionManagement
middleware.delete ActiveRecord::QueryCache
end
See the terminal rake middleware
For Rails 5:
If you are generating a new app
Use --skip-active-record option to generate an application without a database:
rails new myApp --skip-active-record
Notice the extra hyphen '-' as opposed to previous versions of Rails.
For Rails Plugins (or gems) with a spec/dummy app
When your rails app lives in spec/dummy and you start your server from the plugin-root directory. You might still getting following error:
Cannot load `Rails.application.database_configuration`: Could not load database configuration. No such file - ["config/database.yml"]
To avoid this, remove require rails/all inside the file bin/rails and require frameworks you want to use, for example:
# Pick the frameworks you want:
require "active_model/railtie"
require "active_job/railtie"
# require "active_record/railtie"
require "action_cable/engine"
require "action_controller/railtie"
require "action_mailer/railtie"
require "action_view/railtie"
require "sprockets/railtie"
require "rails/test_unit/railtie"
For Ruby On Rails version 5.1.x
require "rails"
# Pick the frameworks you want:
require "active_model/railtie"
require "active_job/railtie"
# require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "action_view/railtie"
require "action_cable/engine"
require "sprockets/railtie"
require "rails/test_unit/railtie"
I am trying to replicate the behavior of passing the -O option when generating a new Rails application. However, I can't find the source of this behavior. What do I need to do to replicate this behavior and/or find the source that determines this behavior?
That option is only used in one spot in the template for config/application.rb. To replicate it yourself, add separate requires for each of the Rails components you want to application.rb:
Instead of this:
require 'rails/all'
Use this:
require "rails"
# Pick the frameworks you want:
require "active_model/railtie"
require "active_job/railtie"
# require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "action_view/railtie"
require "sprockets/railtie"
require "rails/test_unit/railtie"
The same logic for the requires is used if you specify any of these flags: --skip-active-record, --skip-test-unit, or --skip-sprockets.

I created a rails app with the -O option (i.e. without ActiveRecord). But now I want to add active record to it. How can I accomplish that?
Inside of config/application.rb you should see where the ActiveRecord railtie is commented out (see below).
# Pick the frameworks you want:
# require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "active_resource/railtie"
require "sprockets/railtie"
require "rails/test_unit/railtie"
Uncomment it.
Also make sure to add a database.yml file and the a database adapter gem (e.g. sqlite3) to your Gemfile.
I'm a Ruby on Rails Amateur currently learning from Michael Hartl's RailsTutorials.
I followed instructions on Ror tutorial, and after Listing 3.5, I didn't get the expected outcome.
After running Rails S, there is no home page or contact page shown at the given URL, and this was the error shone on the Web Browser.
ActiveRecord::ConnectionNotEstablished
Rails.root: /Users/username/rails_projects/sample_app
Anyone can help?
I ran into exactly the same problem when going through the (otherwise brilliant) tutorial.
What helped me was commenting out a line in config/application.rb. Here is what rails generates when running rails new sample_app -T on my system:
require File.expand_path('../boot', __FILE__)
# Pick the frameworks you want:
require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "active_resource/railtie"
require "sprockets/railtie"
# require "rails/test_unit/railtie"
...
After doing some research on the internet I found this, which helped a lot. So here is what I did:
I commented out the line require "active_record/railtie", removed the comment from the line require "rails/test_unit/railtie" and added another line like so:
require File.expand_path('../boot', __FILE__)
# Pick the frameworks you want:
# require "active_record/railtie"
require "action_controller/railtie"
require "action_mailer/railtie"
require "active_resource/railtie"
require "sprockets/railtie"
require "rails/test_unit/railtie"
# For errors like ActiveRecord::RecordNotFound
require "active_record"
Now everything works just fine.
N.B.: I'm just a Rails rookie myself who ran into this exact problem, so you should take this answer with a grain of salt ...
