# Returns the public URL of the attachment with a given style. This does
# not necessarily need to point to a file that your Web server can access
# and can instead point to an action in your app, for example for fine grained
# security; this has a serious performance tradeoff.
#
# Options:
#
# +timestamp+ - Add a timestamp to the end of the URL. Default: true.
# +escape+ - Perform URI escaping to the URL. Default: true.
#
# Global controls (set on has_attached_file):
#
# +interpolator+ - The object that fills in a URL pattern's variables.
# +default_url+ - The image to show when the attachment has no image.
# +url+ - The URL for a saved image.
# +url_generator+ - The object that generates a URL. Default: Paperclip::UrlGenerator.
#
# As mentioned just above, the object that generates this URL can be passed
# in, for finer control. This object must respond to two methods:
#
# +#new(Paperclip::Attachment, Paperclip::Options)+
# +#for(style_name, options_hash)+
def url(style_name = default_style, options = {})
default_options = {:timestamp => @options.use_timestamp, :escape => true}
if options == true || options == false # Backwards compatibility.
@url_generator.for(style_name, default_options.merge(:timestamp => options))
else
@url_generator.for(style_name, default_options.merge(options))
end
end
По умолчанию скрепка добавляет параметр отметки времени, передавая :timestamp => false
в url
метод вашего вложения:
image = Magick::ImageList.new('public' + @picture.photo.url(:original, :timestamp => false))
# => "public/system/photos/115/original/Kitchener-2011103100531.jpg"
Редактировать: На самом деле, похоже, они изменили имя опции, так как это не работало для меня с Paperclip 2.4.0.После проверки моего собственного источника, опция :use_timestamp
, но на github это :timestamp
- выберите, какой из них зависит от используемой версии Paperclip.
