For all istructions refers to git://github.com/Squeegy/fleximage. I add a rails3_view.rb to manage template in rails3.
#rails3_view.rb
module ActionView
module TemplateHandlers class Rails3View < TemplateHandler include Compilable class TemplateDidNotReturnImage < RuntimeError #:nodoc: end def compile(template) <<-CODE @template_format = :flexi controller.response.content_type ||= Mime::JPG result = #{template.source} requested_format = (params[:format] || :jpg).to_sym begin # Raise an error if object returned from template is not an image record unless result.class.include?(Fleximage::Model::InstanceMethods) raise TemplateDidNotReturnImage, ".flexi template was expected to return a model instance that acts_as_fleximage, but got an instance of instead." end # Figure out the proper format raise 'Image must be requested with an image type format. jpg, gif and png only are supported.' unless [:jpg, :gif, :png].include?(requested_format) result.output_image(:format => requested_format) rescue Exception => e e end CODE ensure GC.start end end end
end
