How would I be able to generate a pdf file when a button is clicked?
I have a user profile page and when I hit print, it should generate a pdf file containing the data of that user.
Thanks in advance.
There are a lot of difference PDF generation ruby libraries but I would recommend prawn. For example:
require 'prawn'
Prawn::Document.generate('hello.pdf') do |pdf|
pdf.text("Hello Prawn!")
end
Here is an excellent railscast that goes through the basics which should get you on the right track.

I have an existing PDF template that I'd like to fill out within a Rails application and save to a new PDF. Is there a way to do this using Wicked PDF or is there another tool or gem better suited to the task?
Wicked PDF is used for converting HTML to PDF. Not for filling out existing PDF forms or templates.
A quick google search returned HexaPDF or Origami as potential options for editing PDF files with Ruby.
wicked pdf is not for filling existing pre created pdf. you may need to look at prawn, prawn-form for that. Its DSL based pdf library for ruby and ruby on rails.
A quick search got me into this issue.
please take a look, wicked pdf issues github
I would like to generate PDF forms with radio buttons and submit buttons in it by using Ruby on Rails. Does anyone know if there is a Gem that can help with this task?
I've looked into
Prawn,
Wicked PDF, and
PDFKit
but they don't seem to have this feature. Currently I am just using Acrobat Pro to create my PDF and insert the form manually but would like to automate this with a Gem if possible.
Any help would be appreciated, thanks.
EDIT
I just found 2 gems that can help insert radio buttons, check boxes, etc. while generating a PDF in rails: prawn-blank and prawn-forms. It doesn't seem like they are being maintained anymore but they should still be useful. Hope this is useful for others attempting to automate generating interactive PDF files too.
There's also RTeX. That works well if you're willing to translate to LaTeX first. LaTeX is a very good way to store marked-up documents. It just depends on how static each document is.
You can use right-signature to complete your task

anyone knows about some gem or app in rails to create pdf docs from html5 and css3 with some client side programming??
Thanks ;)
Thank you for your responses. I need this for a possible project wich will use jquery for box positioning and then, will export the resultant html to pdf. Roughly, ¿is this possible?
PDFKit and WickedPDF for Client side generation, as suggested by Raphael and jcadam

Personally, I got more accomplished by using Prawn PDF generator. It's capabilities are much more extensive, IMHO.
Prawn for Ruby PDF generation: https://github.com/prawnpdf/prawn
WickedPDF: https://github.com/mileszs/wicked_pdf
I'm using it now and rather like it:
"Wicked PDF uses the shell utility wkhtmltopdf to serve a PDF file to a user from HTML. In other words, rather than dealing with a PDF generation DSL of some sort, you simply write an HTML view as you would normally, then let Wicked take care of the hard stuff."
If you need more control, also check out Prawn: https://github.com/prawnpdf/prawn. Though Prawn is not an HTML -> PDF converter and is more useful for creating PDFs from scratch.
I'm using both Prawn and WickedPDF on my current project: WickedPDF to generate 'printable' versions of web pages, and Prawn for generating detailed PDF reports.
I believe the PDFKit gem may be what you're looking for.

There's also IMGKit if you want images instead of PDFs.

I was wondering if there is a helper method, which can create a link to download a pdf file?
Thank you,
If you are looking to generate a PDF you will need to use something like Prawn or PDFKit. If you simply need to link to an existing PDF, just use link_to.
Can anybody show me (maybe copy/paste a simple code example) how to create the .pdf file from an existing (.xls) file, using the Prawn gem? (Basically, I'd need the command that "opens" the existing file.)
(I'm asking because the Prawn documentation (http://prawn.majesticseacreature.com/docs/) seems to be gone since quite a while - it's not even usable via Google cache...)
Thanks a lot for any help with this!

I'd suggest that you break the problem down.
Can you read xls with Ruby? Possibly, but it's flaky at best. However, you can easily read csv, and xls exports nicely to that format.
Can you write a 'table' of values to a prawn pdf? Yes
So, (almost) all you need is a little program that can parse a csv file into a prawn-friendly table-structure and then hand it off to Prawn for generation.
Turns out the Prawn gem cannot handle existing files...
Prawn can be used to render content on top of a PDF. You're talking about .xls, a completely different format.
