class Post < ActiveRecord::Base
  class Index < Trailblazer::Operation
    include Collection
    include CRUD
    model Post

    def model!(params)
      Post.where(forum_id: params[:forum_id])

    end
  end
end
RSpec.describe Post::Index, type: :operation do
  it { is_expected.to be_a_trailblazer_operation }
  it { is_expected.to use_model Post }
  it do

RSpec.describe Post::Show, type: :operation do
  it { is_expected.to be_a_trailblazer_operation }
  it { is_expected.to use_model Post }
  it do
    is_expected.to present_model.with_params(forum_id: 1, id: 11).from_model(Post).wich_receive(:find_by!).with(forum_id: 1, id: 11)
  end
end

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
