ruby_template_handler¶ ↑

• github.com/mschuerig/ruby_template_handler

A Rails view template handler that renders Ruby objects to JSON.

• I’m not entirely sure how sensible this whole thing is, but there you go.

A controller action for returning a list of Movie objects in JSON format

# app/controllers/movies_controller.rb
def index
  respond_to do |format|
    format.json do
      @movies = Movie.all
      @count = Movie.count
      render :template => 'movies/index.json.rb'
    end
  end
end

# app/views/movies/index.json.rb
{
  :identifier => Movie.primary_key,
  :totalCount => @count,
  # render @movies does not work as it insists on returning a string
  :items => @movies.map { |m| render(m) }
}

# app/views/movies/_movie.json.rb
{
  :id => movie.to_param,
  :title => movie.title,
  :releaseDate => movie.release_date
}

In general, “full” templates are rendered to strings, whereas partials are rendered as objects.
