Hello,
Which is a good tutorial to generate a PDF with Rails 3.0.9?
I found a lot of tutorials but they are all out of date or incomplete.
I would like to have another view to display for the "show" action, somenthing like:
format.pdf { :layout=>'pdf_layout' }Thanks to all
If you want to construct pdf's from scratch, you can try
http://www.cracklabs.com/prawnto
Even though the website says only tested on 2.2, it apparently works on 3
If you want to build pdf's in some other tool, and do things like form fills, assemble pdf's from component pdf's, etc. within Rails, you can try pdftk:
http://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/
I use pdftk to do form fills on pdf's I create with Illustrator / Acrobat Pro
prawnto use a prawn, a very powerfull tool, maybe it is quite hard...
What about a "wkhtmltopdf" based solution? Is it reccomandable?
However I'll spend some time to study prawnto.
For the second point, how can I set up a link_to that make the "show" action respond with the format.pdf instead of the frmat.html?
Thank you.
So long as your route has the optional (:.format) tacked on to the end
Then if you request the action like:
You'll call the bar action in foo_controller and the
def bar
respond_to do |format|
format.pdf {:render #whatever}
end
end
will work
I tryed to use prawnto with rails 3.0.9.
I'm using this videocast as tutorial: http://railscasts.com/episodes/153-pdfs-with-prawn
I installed prawn:
man-10-21-2-67:gesba user$ bundle list
Gems included by the bundle:
[...]
* prawn (0.12.0)
[...]and I installed the prawnto plugin:
man-10-21-2-67:gesba user$ rails plugin install --force git://github.com/prior/prawnto.git

From git://github.com/prior/prawnto
* branch HEAD -> FETCH_HEADI created the show.pdf.prawn file with
pdf.text "Hello World"But I get a "file not found" error when I try to point my browser to http://localhost:3000/pay_checks/1.pdf
any suggestion?
In the video tutorial, the format.pdf in the controller is missing
So long as your route has the optional (:.format) tacked on to the end
Then if you request the action like:
www.yourapp.com/foo/bar.pdf
will work
How can I set up a link_to to respond with the format.pdf
link_to 'Get PDF' , ???_path(:format=>'pdf')
just pass :format=>'pdf' to whatever url_helper you are using
I'm using this code:
<%= link_to 'Generate PDF', pay_check(:format => 'pdf'), :class => 'btn grey small' %>And I also added this route:
get '/pay_checks/:id(.:format)' => 'pay_checks#show'But I get a NoMethodError error:
NoMethodError in Pay_checks#index
[...]
undefined method `pay_check' for #<#<Class:0x10f96fd10>:0x10f96dc68>
I would like to get this link: http://localhost:3000/pay_checks/6.pdf
<%= link_to 'Generate PDF', pay_check_path(:id=>1, :format => 'pdf'), :class => 'btn grey small' %>
That should get you the show action in your pay_check_controller, passing id = 1.
run
rake routes
and post what you get
You should notice that the route you added is redundant
This is the result of the rake routes:

I'm using a "test" account and there is Rails 2.3.2 installed (when I'll purchase the hosting I'll be able to update it)
With Rails 2.3.2 I get a "Missing template" error when I generate the pdf:
Missing template pay_checks/show with {:locale=>[:en, :en], :formats=>[:pdf], :handlers=>[:builder, :erb, :rjs, :rhtml, :rxml]} in view paths "/accounts/user/www/test/app/views"Since I'm using prawnto I'm using the show.pdf.prawn template which don't appera in the handlers list.
This problem will be fixed using Rails 3.x?
Thanks for your help

Is the prawn gem on the production environment?
Yes, also the same version (0.12.0)
user@remotehost:~/www/test$ bundle187 list prawn
/accounts/user/www/test/vendor/gems/ruby/1.8/gems/prawn-0.12.0Check this:
https://github.com/sandal/prawn/wiki/Us … th-Bundler
I'm not using git to get prawn.
I'm using the bundle install to get all the gems I need, then I do the "bundle pack" then I move the app to the hosting ant there I do a bundle install again.

Worth a try.
Here is what I see as the problem, in the error you posted there is this:
:handlers=>[:builder, :erb, :rjs, :rhtml, :rxml]There should be a 'pdf' in there, which is (I THINK) normally done by the prawnto plugin
So I think prawn is probably installed OK, but the prawnto plugin isn't installed correctly for 2.X.
You may find an answer here:
https://github.com/sandal/prawn/wiki/Us … n-in-Rails
I agree with you, the problem is that prawnto didn't add the :prawn to the handler list.
I didn't find any answer to my problem in your link, the problem is not prawn but prawnto.
First of all the link in the homepage of the prawnto project on github (https://github.com/thorny-sun/prawnto) isn't active I used this one: https://github.com/prior/prawnto and in the wiki I found this guide to install it with rails 2.2 (https://github.com/prior/prawnto/wiki/Use).
I added the line
config.gem “prawn” to the enviroment.rb but I get an error when I restart the webserver:
config/environment.rb:7: undefined local variable or method `config' for main:ObjectAt the moment... I hope the problem will be solved with rails update to the 3.0.x ...
