Weird problem with Rails and Adobe Livecycle pdf

Question

I'm building a site in which a catalog (of products) is shown and when clicked a Adobe Livecycle generated pdf will be opened. There are a few form fields and when the submit button is pressed, the fields will be submitted to the url http://localhost:3000/pdf-parser.

This file gets all the parameters and can store them in the database. The problem is to identify which user is sending the data via Pdf? This could be accomplished if I could inject some parameter like user_id into the Livecycle pdf file which would get passsed to the http://localhost:3000/pdf-parser so that I can stamp the user.

I googled for this several times but I couldn't get the answer to this as Adobe Livecycle is a new product.

So, can any Rails coder point me in the right direction? Or is this even achievable? Or is there any other solution to this problem?

Answer 1

I resolved it using the XFA xml file and dotNet custom built renderer library.

Answer 2

If you set any cookies when sending the pdf over to the user (e.g. go ahead and store something inside the controller's session object, e.g. session[:user_id]=1234), does Acrobat send back the cookies alongside the submitted form data? (e.g. is session[:user_id]=1234?) If so, then you have your answer.
