HTML5 Uploader Generates 'HTTP Error'

[podblog]

Hi Espen,

I just finished installing Balder at http://tenc.herokuapp.com/ following your guide on:

http://blog.inspired.no/rails-photo-gallery-balder-on-heroku-and-s3-726/

The app itself runs, but I am having upload issues. I've tried everything documented here, but nothing has worked. I also looked at plupload documentation and the documentation doesn't get into your methods (RoR) in any detail.

I intend on uploading my images to S3. I've specified everything in balder.rb in terms of my AWS credentials, and have made the adjustment to force HTML5 uploads.

I know these details are vague but I'm fairly new at using Heroku and Rails, so any assistance is appreciated. I'll gladly provide more details as needed...since I'm not quite sure what you would need from me other than a detailed description?

Thanks for your help...

I've done a little work since then, it appears the upload might be getting stuck on something related to exiftool. I disabled exiftool per your instructions in the docs, though...

Try commenting out "before_create :exif_read" in the photo model. I will look into this later but currently too busy with other work.

[podblog]

This worked. I commented out line 13 in the photo.rb model. Thank you for your help!

I get IO errors when uploading with the HTML5 uploader. The upload stops at 60% or 80%. Depending on the file.

[podblog]

Have you tried commenting out line 13 in photo.rb? If you are on Heroku, the EXIF module causes problems and isn't really necessary to the successful operation and deployment of Balder.

@nullmedium where are you storing the files? On disk or S3? Are you using Heroku? Also see the tip above.

[nullmedium]

@espen On disk. I created an uploads folder within the rails root directory.
In Chrome the uploads aborts and in Safari it stalls. The file is 2 MB in size.

I tried to comment out the line.

Edit: The application is hosted on my own server.

[espen]

What does the log say? Can you try with another file? And perhaps a smaller file?

[nullmedium]

I found the problem. The apache process does not the proper permissions to write into the
/tmp/passenger.1.0.17724/generation-0/buffered_uploads directory!

[espen]

Good to hear you fixed it :)
