我有一個名爲每頁個人用戶的PDF動作,它有兩個模式,即從數據庫retrives信息的用戶模式通信,但只有所有用戶都具有特定的信息,然後它將信息發送給模型報告,然後當我檢查每個用戶的屬性時,它顯示的方式是我沒有從模型用戶調用它,它需要每對並把它放在一個不同的順序,所以當我寫信息到PDF上的表格它顯示它不好,像首字母縮寫可能是我的表的最後一個記錄和手機可能是第一個..我必須創建一個新的對於每一個用戶的信息頁面..哈希值之前,我的一個PDF打印出來的表格裏面我怎麼能進行排序
我的報告的代碼看起來的一樣:
def self.generate_individual_pdf(people,residents,user,estate = nil, title = nil)
pdf = PDF::Writer.new
title = !title ? "Report" :title
pdf.select_font "Times-Roman"
pdf.text "<em>Compiled By: #{user.presentation_name}</em> <em>Estate: #{estate.name}</em> <em>Created On: #{Time.now.strftime('%d/%m/%Y %H:%M')}</em>", :justification => :center
x = 0
25.times do
pdf.text ""+" "
x+=1
puts x
end
pdf.text "<em>User Report For: #{estate.name}</em> ", :font_size => 18, :bold => true, :justification => :center
if estate.logo
pdf.image "#{RAILS_ROOT}/public"+estate.logo.public_filename,:width => 100, :height => 100, :resize => 1.1, :justification => :center
end
y = 0
#loop people to create table for every person
people.each do |p|
pdf.start_new_page
pdf.text" "+p.Title.to_s+" "+p.Firstname.to_s+" "+p.Lastname.to_s, :font_size => 12, :justification => :center
pdf.text ""+" "
pdf.text ""+" "
pdf.text "Please verify if your details below are correct, and rectify them in the third column of the table.", :font_size => 8
pdf.text ""+" "
table = PDF::SimpleTable.new
table.column_order.push(*["head1","head2","head3"])
headings = ["head1","head2","head3"]
headings.each do |h|
table.columns[h] = PDF::SimpleTable::Column.new(h)
table.columns[h].heading = h.humanize
end
#display tables
table.show_headings = false
table.orientation = :right
table.position = :left
data = []
p.attributes.each_pair do |h|
data << { "head1" => h[0], "head2" => h[1], "head3" => " "}
end
table.data.replace data
table.render_on(pdf)
i = 0
28.times do
pdf.text ""+" "
i+=1
puts i
end
pdf.text "Kind Regards"+ " "+p.Title.to_s+" "+p.Firstname.to_s+" "+p.Lastname.to_s, :font_size => 11
pdf.text ""+" "
pdf.text "Signature "+"......................................."
end
那麼它產生的輸出,當它循環throught的p.attribute.each_pair做| H | 數據< < { 「頭像1」=> H [0], 「HEAD2」=> H [1], 「頭像3」=> 「這應該是零」} 端
請人我一直試圖使用所有這種排序,但我只是不能得到正確的答案..任何人可以幫助請隨時..感謝提前。
