Module: Arbre::Rails::Rendering

Defined in:
lib/arbre/rails/rendering.rb

Overview

Template rendering strategies for Arbre.

Partials

Simply use the method #partial instead of render :partial => ‘…’.

*edit.html.arb:*

fieldset do
  partial 'fieldset'
end

*_fieldset.html.arb:*

# Note: `self' is the same `self' as in the template above!
label :something
text_field :something

To pass another context than self:

*edit.html.arb:*

form do |form|
  fieldset do
    partial 'fieldset', context: form
  end
end

*_fieldset.html.arb:*

# Note: `self' is now the form defined in the template above.
label :something
text_field :something
