Factory Girl / Rails: Generator to create a factory for existing model?

I am using the rspec_rails and factory_girl_rails gems within my Rails project. All of the models are already created. Is there a generator that I can run that will create the factory file for an existing model?

Ex: I already have a Blog model. RSpec allows me to generator a model spec file at spec/models/blog_spec.rb by simply running the following:

rails generate rspec:model blog

Is there a generator that I can run in the command line that will generate the factory file for this existing model, located at: spec/factories/blogs.rb?

I did not see any mentions of generators within the factory_girl_rails docs.

Solution

  • First configure Factory Bot.

    config.generators do |g|
  g.fixture_replacement :factory_bot, dir: "spec/factories"
end

    Then run the generator.

    rails g factory_bot:model Blog name description total_visits:integer
