Hello All:
I have been working with <a
href="http://ruby-pdf.rubyforge.org/pdf-writer/index.html">Austin
Ziegler''s PDF::Writer</a> as a means to produce PDF documents
from my
Rails app. I am stumped on how to iterate through a collection of items
and output them in a table format. The way I have tried it so far only
returns the last item in the collection - every other variation I have
tried errors out.
All of the documentation I can find only deals with static data,
manually entered in the controller when using the Simpletable class. It
is working, except only the last item in the collection shows in the
generated PDF. Any ideas?
My code follows:
def pdf
@item = Item.find(:all)
_p = PDF::Writer.new
_p.select_font ''Times-Roman''
PDF::SimpleTable.new do |tab|
tab.title = "Item List"
tab.column_order.push(*%w{item_code item_name item_desc
item_cost})
tab.columns["item_code"] =
PDF::SimpleTable::Column.new("item_code") { |col| col.heading =
"Code" }
tab.columns["item_name"] =
PDF::SimpleTable::Column.new("item_name") { |col| col.heading =
"Item" }
tab.columns["item_desc"] =
PDF::SimpleTable::Column.new("item_desc") { |col| col.heading =
"Description" }
tab.columns["item_cose"] =
PDF::SimpleTable::Column.new("item_cost") { |col| col.heading =
"Cost" }
tab.orientation = :center
tab.bold_headings = true
@items.each do |item|
@item_data = [
{ "item_code" => item.code,
"item_name" => item.name,
"item_desc" => item.desc,
"item_cost" => item.cost},
]
end
tab.data.replace @data
tab.render_on(_p)
end
send_data _p.render, :filename => "Item_List.pdf", :type =>
"application/pdf"
end

Just have a brief moment to help out, this code snippet is from my
own code (obviously! lol).
from Controller:
@work_order_items = WorkOrderItem.find(:all)
render :template => "work_orders/work_order", :type =>
"rpdf", :layout => false
from View:
@work_order_items_table = PDF::SimpleTable.new
@work_order_items_table.column_order = [ "Quantity", "Part
#",
"Description", "Price", "Extended"]
@work_order_items.each {|item| @work_order_items_table.data << Hash
["Part #", item.products_and_services.part_number,
"Description", item.description,
"Quantity",item.quantity,
"Price", number_to_currency(item.price),
"Extended", number_to_currency(item.sub_total)]}
<snip other code>
@work_order_items_table.render_on(pdf) if !
@work_order_items_table.data.empty?
Hope the above helps.
I''ll back online in a couple of hours. Let me know if I can help more.
cheers,
Jodi
