重写 Rails 中的辅助方法

Question

I have following line in my rails helper .

  config.use_transactional_fixtures = true

But I want to modify it to

  config.use_transactional_fixtures = false

But I don't want to modify it for every tests inside spec folder. I just want to apply it to all the tests inside spec/requests folder.
How can I do it ?

After doing a bit more research, it looks like you need to use the DatabaseCleaner gem https://github.com/DatabaseCleaner/database_cleaner . In your rails helper, you would add this:

require 'database_cleaner'

RSpec.configure do |config|
  config.use_transactional_fixtures = false

  config.before type: :request do
    DatabaseCleaner.strategy = :truncation
  end

  config.after type: :request  do
    DatabaseCleaner.strategy = :transaction
  end

  config.before :each do
    DatabaseCleaner.start
  end

  config.after do
    DatabaseCleaner.clean
  end
end

This will set you up so that request specs will use the truncation strategy (removing all data from the database) and everything but request specs use transactions (rollback all changes from runnning scenario).
