Ok i''ve gotten the file upload working (I have users uploading images
basically to be viewed on another page) but not sure how to display it
on a facebook canvas. Do I need to present it in a iframe?
PhotosController:
def code_image
@image_data = Photo.find(params[:id])
@image = @image_data.binary_data
send_data(@image, :type => @image_data.content_type, :filename =>
@image_data.filename, :disposition => ''inline'')
end
show.fbml.erb:
<% for column in Photo.content_columns %>
<%= column.human_name %>
<% if column.name == "binary_data" %>
<%= image_tag("/photos/code_image/#{@photo.id}", :alt
=>
"Image") %>
<% else %>
<%=h @photo.send(column.name) %>
<% end %>
<% end %>
the URL i''m directly going to to view the image:
http://apps.new.facebook.com/myapp/photos/code_image/1
If I view the source html it shows a bunch of binary code of the image
in the fbml source
Is that path relative to RAILS_ROOT/public/images? Appears your trying to use a controller path to access the images. I think image_tag inherently uses RAILS_ROOT/public/images prepended to to the string, unless a fully qualified URL is provided, which seems your trying to use a relative path.

Actually I got most of the code from here: http://railsforum.com/viewtopic.php?id=4642 They explicitly use the image_tag which is ultimately calling a method in the controller. In the fbml source when I hit the url it just fires up bunch of binary in the page . So it''s finding the image blob but not rendering it correctly.

I see your point now.. This is tricky. If I go to my host URL it auto redirects back to facebook. Looks like I''m gonna have to set a route up or something..

So i guess my question then is, how do I setup a route so that if I do "www.myhost.com/photo/show/1" it will not go thru facebook but instead go directly to my host.

Well my prob is I can''t even do "www.myhost.com/photo/show/1 <http://www.myhost.com/photo/show/1>". If I do that it redirects to my apps.facebook.com/myapp I''m not sure how to bypass that.

[Facebooker-talk] rendering images from a file upload
I think you need to skip the authentication filter for that controller. skip_before_filter :ensure_authenticated_to_facebook Then it won''t redirect back to facebook.

After you accept the upload, how to you redirect back into the facebook
canvas? My create method in my controller doesn''t redirect back into
apps.facebook.com/myapp/photos but rather www.myhost.com/photos:
def create
@photo = Photo.new(params[:photo])
if @photo.save
flash[:notice] = "Photo Saved"
redirect_to photos_url
else
render :action => "new"
end
end
