Carrierwave; multiple uploaders or just one?

I have a post model and a podcast model. Both models have an attribute titled: image. I'm using one Carrierwave uploader (named ImageUploader) to handle both models. I have two questions befo开发者_运维百科re I go into production.

Dumb question:

Is it ok to use the same uploader for two different models when they both have the same attribute name for their file attachements? sorry if it seems obvious

Main question:

I want to create three versions of each blog post image (thumb, large, sepia) and only 1 version of each podcast image (thumb).

Do I need to use two uploaders now or can I namespace with the one that I'm already using?

Again it probably seems obvious. I could probably have written the second uploader in the time its taken me to ask these questions

You can use the same uploader on different models even if they have different attribute names. e.g.

class Post
  mount_uploader :image, ImageUploader
end

class Podcast
  mount_uploader :photo, ImageUploader
end

Whether or not you'd want to is a different matter. In your case, I'd create different uploaders for each model, because they have different requirements. You can always use subclasses if you want to keep your code dry:

class ImageUploader < Carrierwave::Uploader::Base; end  # thumbnail
class PostImageUploader < ImageUploader; end  # thumbnail (from superclass), large & sepia
class PodcastImageUploader < ImageUploader; end # thumbnail (from superclass)
