# File lib/mail_engine/mail_template_resolver.rb, line 9 def find_templates(name, prefix, partial, details) template_path_and_name = prefix.include?("mail_engine/mail_dispatcher") ? normalize_path(name, nil) : normalize_path(name, prefix) conditions = { :path => template_path_and_name, :locale => normalize_array(details[:locale]), :format => normalize_array(details[:formats]), :handler => normalize_array(details[:handlers]), :partial => partial || false } MailTemplate.where(conditions).map do |record| initialize_template(record) end end
initialize_template(record)

Initialize an ActionView::Template object based on the record found.
# File lib/mail_engine/mail_template_resolver.rb, line 37 def initialize_template(record) source = record.body identifier = "mail template - #{record.id} - #{record.path.inspect}" handler = ActionView::Template.registered_template_handler(record.handler) details = { :format => Mime[record.format], :updated_at => record.updated_at, :virtual_path => virtual_path(record.path, record.partial) } ActionView::Template.new(source, identifier, handler, details) end
normalize_array(array)
click to toggle source
Normalize arrays by converting all symbols to strings.
# File lib/mail_engine/mail_template_resolver.rb, line 32 def normalize_array(array) array.map(&:to_s) end
normalize_path(name, prefix)
click to toggle source
Normalize name and prefix, so the tuple [“index”, “users”] becomes “users/index” and the tuple [“template”, nil] becomes “template”.
# File lib/mail_engine/mail_template_resolver.rb, line 27 def normalize_path(name, prefix) prefix.present? ? "#{prefix}/#{name}" : name end
virtual_path(path, partial)
click to toggle source
Make paths as “users/user” become “users/_user” for partials.
# File lib/mail_engine/mail_template_resolver.rb, line 53 def virtual_path(path, partial) return path unless partial if index = path.rindex("/") path.insert(index + 1, "_") else "_#{path}" end end
