Chris, did you modify Paperclip to work with CloudFront?

We are just about to.

Comment on 'RSpec, autotest and Snarl on Windows' by zaj

I've followed the instructions here on 2 projects now and always run into a problem... when I run autotest from my app's root directory, I get a line that says:

"loading autotest/rails"

and it just hangs there.

I'm on Vista and running rails 1.2.6.

Any ideas?

The best way to understand Amazon CloudFront is to work through the Getting Started Guide.

Comment on 'Goodbye attachment_fu, hello Paperclip' by Rob Anderton

To follow up on my earlier comment to Peter, there are two gotchas to be aware of if you have a model named Attachment and want to use it in a has_many association.

You must explicitly define the attachment class name when defining the association, otherwise you'll get an error like NoMethodError: undefined method `quoted_table_name' for Paperclip::Attachment:Class when you try and access the association. For example:
```
has_many :attachments, :class_name => '::Attachment'
```
The current version of Paperclip creates a naming conflict with an association named attachments. I've posted a patch but in the meantime you can monkey patch your model with something like this:
```
def attachment_for name
  @_paperclip_attachments ||= {}
  @_paperclip_attachments[name] ||= Attachment.new(name, self, self.class.attachment_definitions[name])
end
```

I’ve just posted a patch for Paperclip to fix a few problems with failing tests and corrupted attachments after using reprocess! on our beloved Windows systems. I decided against including the Tempfile patch and have updated this blog to note that I no longer think this is needed.

@Jim: thanks for the original tutorial and for your recent advice - yeh I will get a mac :D

@Peter: don’t forget there’s nothing stopping you having a special model for your attachments just like attachment_fu, then you can has_many :attachments in the parent model just like the good old days!

@Roob: good thing to remember - my image content type list currently looks like this:

[ 'image/gif', 'image/png', 'image/x-png', 'image/jpeg', 'image/pjpeg', 'image/jpg' ]

Great in-depth tutorial! Remember to allow the content type 'image/pjpeg', otherwise that godforsaken Internet Explorer fails.

Sometimes using attachment_fu is really better. When we want to attach many files or we want to moderate big amount of files - attachment_fu is only way.

Really good and usefull article, man. Thank you!

Good work, chaps.

I've been meaning to add half of this stuff to my old post for ages but alas, laziness always gets the best of me.

Thanks for the link :)

Great plugin so easy to setup and use. Just some additions that are not so obviouse from the rdoc.

To configure paperclip you can add the following statements to your environment file

# this is essential if you do not have ImageMagick in your search path
Paperclip.options[:image_magick_path]='Path/to/ImageMagick/executables'
# this makes paperclip complain if no resizing is not possible
Paperclip.options[:whiny_thumbnails]=true

In a spooky case of great minds thinking alike, Ryan Bates also posted a RailsCast covering Paperclip this week! I’ve added a link to it in the post, but thought it was worth a mention here too in case you missed it.

@DMitry: good question! I’ve added a new section about custom validations using MP3 files as an example so hopefully it’ll help.

@Jon: you’re welcome and thanks for the plugin. Would be nice for us long-suffering Windows users to have the Tempfile patch in the plugin, one less thing for us to remember!

Thanks for the write-up! And thanks for that Windows Tempfile patch. I think that's worth adding into Paperclip itself.
