Pdf simpletable help needed

Rails
1

i am trying to generate a pdf of all of the users in an application that
i have built. i am still pretty new to ruby and rails so i don’t know
the best way to go about it.

here is my controller code:

require ‘pdf/writer’
require ‘pdf/simpletable’

class ReportsController < ApplicationController

def test
_pdf = PDF::Writer.new
table = PDF::SimpleTable.new
user_data = []
for user in User.find(:all)
user_data << user.attributes
end
table.data = user_data
table.render_on(_pdf)

send_data _pdf.render, :filename => 'hello.pdf', :type =>

‘application/pdf’
end
end

i couldn’t figure out a better way to get the data out of the user model
than looping through and adding the attributes to an empty array. then i
used the array as my data for creating the pdf table.

currently i am getting an error saying that my columns are not defined,
yet using the console, i can see that my array is formatted just like
the ones in the examples.

any help would be greatly appreciated.
Thanks

You need to define your columns and column order here. You’re missing
something. Your array may be complete, but your table definition
isn’t.

table.data = user_data
table.render_on(_pdf)

After you define your columns, the above will work.
