Add both faker and dumped_railers gems to your Gemfile:
gem 'faker'
gem 'dumped_railers', require: false
Run bundle install to install the gems.
Create a custom preprocessor to use fake values for first_name, last_name, and email:
class FakeUserDataPreprocessor
def call(model, attrs)
if model == User
attrs['first_name'] = Faker::Name.first_name
attrs['last_name'] = Faker::Name.last_name
attrs['email'] = Faker::Internet.email
end
end
end
Use the dumped_railers gem to export the users table with the custom preprocessor:
require 'dumped_railers'
require 'fake_user_data_preprocessor'
# Replace 'User.limit(10)' with a more specific query if needed.
DumpedRailers.dump!(User.limit(10), base_dir: 'tmp/fixtures/', preprocessors: [FakeUserDataPreprocessor.new])
This will create a fixture file in the tmp/fixtures/ directory with the User data, including the fake values for first_name, last_name, and email.
To import the data, use the following command:
DumpedRailers.import!('tmp/fixtures')
Please note that the FakeUserDataPreprocessor will replace the original first_name, last_name, and email values with fake data in the exported fixture file. If you want to keep the original data, you may need to create a backup before running this process.
