I have rewritten this post for Rails 3:
http://lassebunk.dk/2011/02/19/paperclip-jpegcam-webcam-rails3/

@makaroni4: Please try the new version – it is using the latest version of Rails and latest version of jpegcam.

[...] Here’s how to get pictures from your webcam into Rails using the Paperclip plugin and jpegcam. It is an update of my previous post: Using Paperclip and jpegcam to get pictures from your webcam into Rails. [...]

I`ve tried php version and it works great (I found file test.php in jpegcam archive). I`ve tried older version of jpegcam and it still doesn`t work with rails.

What version of rails do you use? Mine is 2.3.5, may be this is a problem?

Sounds like something’s wrong with jpegcam then… Maybe you could try your version of jpegcam with another backend solution?

I opened uploaded image in SciTE and compared it to several others *.jpeg files – it starts and ends with same chars and it seems like the uploaded file is *.jpeg but it is broken and it is impossible to view it.

@makaroni4: Maybe you could try opening the file in a text editor to see which format it is?

Ooops)) Seems like I copied Ruby code

*webcam.set_api_url(‘/photos/new/upload’);

Hello there)

Could you please help me with a little problem? The thing is, that I can`t open the uploaded image. Btw I`m using Ruby 2.3.5

The code in the view is

webcam.set_swf_url(‘/webcam.swf’);
webcam.set_api_url(”);
webcam.set_quality(90);
webcam.set_shutter_sound(true, ‘/shutter.mp3′);
document.getElementById(‘webcam’).innerHTML = webcam.get_html(320, 240);

and in the controller I wrote:

def upload
File.open(upload_path, ‘w’) do |f|
#f.write request.headers
#f.write Net::HTTP.get_response(URI.parse(“php://input”)).body
f.write request.raw_post
end
render :text => “ok”
end

private

def upload_path # is used in upload and create
file_name = session[:session_id].to_s + ‘.jpg’
File.join(RAILS_ROOT, ‘public’, ‘uploads’, file_name)
end

After I execute webcam.snap(); function the image appears in the “uploads” folder and its size is 25Kb (seems like photo) but it couldn`t be opened in any photo viewer, browser and so on.

I tried very hard to fix it, but it seems like only you can help me))

Hi There,

What if the computer doesn’t have a webcam? How can I detect it, because I’d like to hide all things related to taking pictures …

Thanks for the response Blake. I haven’t gotten the chance to try this yet. I’m currently working on a different part of the project. I’ll post back when I try it out. Thanks again.
