First off all, it's important to say that I'm just using PRAWN gem, i'm NOT using prawnto plugin.
So... It creates a PDF file, but the question is:
How can I use a list (for example, if I wanna use the name and the mail adress of "@users" from "@users = User.find(:all)") and put that list on the PDF file.
If helps, the syntax i'm using is the following:
def pdf Prawn::Document.generate("name_of_file.pdf") do
*it's here that the code should give me the list*
end end
Thanks for any help.
Problem solved.
But, now, i have a new problem.
It print the list, but also print, for every line of the list, the headers.
The code is the following:
[code]def pdf Prawn::Document.generate 'testa.pdf' do @permissao = Permissao.find(:all) for perm in @permissao @data = [["#{perm.perfil}", "#{perm.usuario_id}"]] table @data, :position => :center, :headers => ['Perfil', 'Usuário'], :row_colors => ['ffffff', '999999'], :vertical_padding => 2, :horizontal_padding => 30 end end redirect_to :action => "index" flash[:msg] = "Arquivo em PDF gerado com sucesso." end[/code]
And if someone think "is just put the "table @data" before the block, well... If I do that, what I did, it will list just one of the @permissao, not all.
Thanks any help.

As you have this inside the loop it is outputting a table for each perm item, so each one will have the headers. You need to build up your @data array with data from all the rows from @permissao then (not inside a loop) call table with the complete array.

Sorry, but how do I can insert all the @data values in other array?
Problem solved.
My controller ends like this:
def pdf Prawn::Document.generate 'testa.pdf' do @permissao = Permissao.find(:all) @data = @permissao.collect { |perm| [perm.perfil, perm.usuario_id] } table @data, :position => :center, :headers => ['Perfil', 'Usuário'], :row_colors => ['ffffff', 'C6D8E2'], :vertical_padding => 2, :horizontal_padding => 30 end redirect_to :action => "index" flash[:msg] = "Arquivo em PDF gerado com sucesso." end
Thanks. 
If you had just waited a few minutes before sending this then someone called Bla would have answered the question for you.

I have a new question.
How do I make to save de PDF file in my desktop, for example?
Thanks again.
It's just put the hole directory in the generate arguments...
But how i can verify if the person is using linux ou windows?
Or if i could make the user choose where to save it... Would be great.
I suspect some of us at least have lost track of what you are asking. Are you asking how to make the user choose where to save a pdf file when you send it to him? If so you need do nothing. When you send a pdf the browser will ask the user whether to open or save it.

I use something like:
def pdf @project = Project.find(params[:id]) filename = @project.name+"-"+Time.now.strftime("%Y-%m-%d-%H%M")+".pdf" filename = filename.gsub(" ","_") send_data @project.as_pdf(params[:type]), :filename => filename, :type => "application/pdf" end
Let the user decide whether they will save or just open it in the browser...
To be honest, i don't get what you said quite well... So i try adding the line "send_data('Projetos_Nao_Iniciados')" at the end of action "pdf"... And do not asks if the user want to download it, but shows that some pdf file was downloaded... But, when i open the file, it shows something like:

Let's see... what you're sending isn't a pdf.
def pdf @project = Project.find(params[:id]) filename = @project.name+"-"+Time.now.strftime("%Y-%m-%d-%H%M")+".pdf" filename = filename.gsub(" ","_") send_data @project.as_pdf(params[:type]), :filename => filename, :type => "application/pdf" end
project class implements an as_pdf method, which encapsulates the generation of the actual pdf (I used PDF::Writer, and have yet to update to a newer method. If it ain't broke, don't fix it). The final statement in that method is pdf.render (pdf is the local var, and render causes the return to be the actual pdf file stream for lack of a better name).
send_data sends the return from that method to the client, with a filename, and the type as "application/pdf", which *should* get the browser to either ask the user what they want to do with it, or open it in the browser.
I haven't used Prawn, but given its genesis, I hope it isn't too different.
