Re: [CommunityEngine] Serving scaled images for posts (first_image_in_body)

[Bruno Bornsztein]

Hi,

Well, you could certainly override the first_image_in_body method with your own logic. Unfortunately, since the image is hardcoded into the HTML, you'll probably have to use Regexes to take the image URL and get the thumb. Here's an example (I do this on Curbly):

  def first_image_in_body(size = nil, options = {})

    styles = configatron.photo.paperclip_options.styles.to_hash.keys

    doc = Hpricot( post )

    image = doc.at("img")

    if image && !image['src'].blank?

      src = image['src']

      if size

        regex = /\_(#{styles.map(&:to_s).join('|')})(\.)(.*)$/

        if match = src.match(regex) #image already has a style

          format = match[3]

          src.gsub(regex, "_#{size.to_s}\\2#{format}")

        else

          regex = /(.*)(\.)([^\/]+)$/

          if match = src.match(regex)

            format = match[3]

            src.gsub(regex, "\\1_#{size}\\2#{format}")

          end

        end

      else

        src

      end

    else

      nil

    end

  end

(Yeah, that's ugly ... sorry).

Hope that helps.

Hi,

Right now, the first_image_in_body method in the posts model leads to the full sized image for any image uploaded into a post. Is it possible to have the url point to the scaled versions of the uploaded images (:thumb or :medium) for the first image in a post?

Thanks for any help!
