Haml support for Cells.
Add this line to your application's Gemfile:
gem 'cells-haml' gem "haml", github: "haml/haml", ref: "7c7c169"
This gem currently only works properly with Haml 4.1, which is not yet released.
Cells doesn't escape except when you tell it to do. However, you may run into problems when using Rails helpers. Internally, those helpers often blindly escape. This is not Cells' fault but a design flaw in Rails.
As a first step, try this and see if it helps.
class SongCell < Cell::ViewModel include ActionView::Helpers::FormHelper include Cell::Haml # include Haml _after_ AV helpers. # .. end
If that doesn't work, read the docs.
This gem works with Tilt 1.4 and 2.0, and hence allows you to use it from Rails 3.2 upwards.
