Rails Faker how to create custom method

I'm using rspec and faker for testing and I want to add a cuestom field on faker, I had followed this instructions:

https://github.com/stympy/faker#customization

So in my rails_helper.rb I have this line:

Faker::Config.locale = :ca

And in my ca.yml under config/locales folder I have:

faker:
    internet:
      usefuldata: [AAAAA,BBBBB]

And when I made Faker::Internet.usefuldata it returns undefined method 'usefuldata' for Faker::Internet:Class. And I want that Faker::Internet.usefuldata return AAAAA or BBBBB.

Thanks in advance.

Faker cannot currently support customization of Internet data.

Faker supports customization only for those classes that contain the flexible method in their definition. Eg: The Faker::Name class has the flexible method

For customizing name, have the locale file - for example, fr.yml - in the following format:

fr:
  faker:
    name:
      region: [South East Queensland, Wide Bay Burnett, Margaret River, Port Pirie, Gippsland, Elizabeth, Barossa]

Here, region is a custom field being added to name.

Note: The first level is fr, not faker.

Other classes that support customization:

  • Faker::Address
  • Faker::Business
  • Faker::Company
  • Faker::Hacker
  • Faker::Team

I have forked the repo and added the ability to customize internet fields. You can try it out by setting the source appropriately in the Gemfile as follows:

gem 'faker', git: 'https://github.com/prakashmurthy/faker.git'

Not too keen on getting this merged into faker gem as useful_data doesn't seem to be a common enough data point for a lot of users.
