Forum: RSpec Testing file attachment with Paperclip

Does someone have an example on faking a file upload for just ensuring
it gets called, without actually uploading the file to s3.
I thought that stubbing Model.has_attached_file would be enough, but
it doesn't seem so ...

This is what I did:

Video.stub!( :has_attached_file ).with( :name ).and_return( true )

has_attached_file is from paperclip, it gets mixed to the model.

1)
RightAws::AwsError in 'VideosController should create a valid Video'
AWS access keys are required to operate on S3
/Users/ngw/zooppa-4/app/controllers/videos_controller.rb:6:in `create'
/Users/ngw/zooppa-4/spec/controllers/videos_controller_spec.rb:17:

Maybe I missed something ?

TIA,
   ngw

I haven't been clear enough, my point is not to fake the file upload
(there's also fixture_file_upload for that) but to fake the receiver,
making it dumb enough to avoid performing every operation on the file
(in my case, uploading to s3).

I'm pretty sure the problem is that by the time you stub has_attached 
file,
which is a class method run when the class is loaded, it's too late. 
Based
on a quick look at the paperclip project site, it looks like what you 
want
to stub is the save_attached_files method on the model INSTANCE, which 
the
has_attached_file registers as an after_save callback.

Rick, I'm interested finding out how to do this, too (Rspec newbie and 
really terrible with mocking & stubbing). Are you suggesting we do 
something like this (?);

Paperclip.saved_attached_file.stub!(:avatar).and_return(true)

It's nice to be able to spec the app actually working with S3 but, my 
specs are taking over 3 minutes now and commenting out all the S3 
involved specs kinda makes me nervous!

I am struggling with Webrat and Paperclip. If I specify:
validates_attachment_presence     :image, then AR complains because 
there is no image set.

Therefore I decide to remove this validation, and instead use:
validates_presence_of :image_file_name, to trick him. But it still 
doesn't work. When I create a new object, even if I put: 
Product.create!(..., :image_file_name => 'thumb1.png'), AR still 
complains and it says that Image file name is missing. There must be 
some Paperclip magic which I can't get around.

The only solution I have found is to remove the validation of the 
attachment for passing the tests, but I'd like to keep it.

Anyone ran into this previously?

G'day again Fernando. IIRC, Paperclip's #save_attached_files is what
takes care of saving the attachment to disk, uploading it to S3, etc.
Here's a small gist that tests the allowance of JPG files, and ensures
that the file isn't saved [to disk, for me]:
http://gist.github.com/48264

I hope that helps!

Hi Nick,

Don't ask me why, but this morning I tried once again to simply do: 
product.image = File.new('path_to_image.png'), and it worked perfectly 
as expected and passed validations and whatever.

I'm glad you got it sorted out  =)

and second one is, from where u get S3 aws_access_key and 
aws_secret_access_key and bucket_base_name .. or from wher to set 
this.........

thanks
