Prawn on Rails

[macsig]

Hello, I'm working on a Rails app and right now to create some PDF I
use PDF::writer but since it is creating my some issues (and because
it is basically dead) I have decided to switch to Prawn.


To start I have a simple question, how can I import in within my app?
I mean after installing the gem have I to add something on my
environment file.
To use PDF::writer I added "require 'pdf/writer'".


Basically what I do is generate a PDF in my model, do I need prawnto ?


THANKS and HAVE a GOOD 1!

yes-- to use the prawn library you will have to require it.
and no-- you don't have to use prawnto and in fact some prefer not to,
however it does make life easier in most normal situations (in my
humble opinion)-- but what else would you expect the prawnto creator
to say.
if you want to try prawnto just follow the instructions at
www.cracklabs.com/prawnto

p.s. a new prawnto version is on its way in the next day or so-- some
nice additional features and a little better documentation..

Thanks Michael for your reply.

I have added config.gem "prawn" in my environment (and restarted
the server).
but when I try to generate a simple PDF I get uninitialized constant
User::Prawn. User is the model within I' trying to generate the PDF.

Am I missing something?


THANKS

pastie your controller and any other relevant bits... or just use
prawnto

The code I use is quite simple


Prawn::Document.generate "foo.pdf" do
font "Times-Roman"
text "Hello World", :at => [200,720], :size => 32
end


Thanks but if it is not necessary I prefer to go without prawnto

I can't believe rails makes things so complicated.

I never learned how to register dependencies because I have no idea
what good it does me.
Instead of messing around with that junk, try just doing:

config.after_initialize do
require "prawn"
end

in your environment.rb. If that has problems... did you um.... gem
install prawn ??

The config.gem stuff is so it will yell at you if you don't have it
installed/can install it with a rake task. Quite convenient actually.

>> Prawn::Document
NameError: uninitialized constant Prawn
from (irb):1

Look's like I've either not got it installed, or not loaded it. Seems
pretty easy to me using the features already built into Ruby.
