Template Engines

Cells supports various template engines.

We provide support for Haml, Erb, and Slim. You can also write your own template engine.

In a non-Rails environment, you need to include the respective module into your cells, so it knows what template to find.

class SongCell < Cell::ViewModel
  include Cell::Erb
  # include Cell::Haml
  # include Cell::Slim

Note that you can only include one engine per class. This is due to problems with helpers in Rails and the way they have to be fixed in combination with Cells.

Multiple Template Engines in Rails

When including more than one engine in your Gemfile in Rails, the last one wins. Since each gem includes itself into Cell::ViewModel, unfortunately there can only be one global engine.

Currently, there’s no clean way but to disable automatic inclusion from each gem (not yet implemented) and then include template modules into your application cells manually.

ERB

Haml

Slim

Your Own

Theoretically, you can use any template engine supported by Tilt.

To activate it in a cell, you only need to override #template_options_for.

class SongCell < Cell::ViewModel
  def template_options_for(options)
    {
      template_class: Tilt, # or Your::Template.
      suffix:         "your"
  }
  end

This will use Tilt to instantiate a template to be evaluated. The :suffix is needed for Cells when finding the view.
