    <p>I wrote this ruby script to scrape product info from the manufacturer website. The scraping and storage of the product objects in an array works, but I can't figure out how to export the array data to a csv file. This error is being thrown: scraper.rb:45: undefined method `send_data' for main:Object (NoMethodError)</p> <p>I do not understand this piece of code. What's this doing and why isn't it working right?</p> <pre><code> send_data csv_data, :type =&gt; 'text/csv; charset=iso-8859-1; header=present', :disposition =&gt; "attachment; filename=products.csv" </code></pre> <p>Full code:</p> <pre><code>#!/usr/bin/ruby require 'rubygems' require 'anemone' require 'fastercsv' productsArray = Array.new class Product attr_accessor :name, :sku, :desc end # Scraper Code Anemone.crawl("http://retail.pelicanbayltd.com/") do |anemone| anemone.on_every_page do |page| currentPage = Product.new #Product info parsing currentPage.name = page.doc.css(".page_headers").text currentPage.sku = page.doc.css("tr:nth-child(2) strong").text currentPage.desc = page.doc.css("tr:nth-child(4) .item").text if currentPage.sku =~ /#\d\d\d\d/ currentPage.sku = currentPage.sku[1..-1] productsArray.push(currentPage) end end end # CSV Export Code products = productsArray.find(:all) csv_data = FasterCSV.generate do |csv| # header row csv &lt;&lt; ["sku", "name", "desc"] # data rows productsArray.each do |product| csv &lt;&lt; [product.sku, product.name, product.desc] end end send_data csv_data, :type =&gt; 'text/csv; charset=iso-8859-1; header=present', :disposition =&gt; "attachment; filename=products.csv" </code></pre>

    1. COWhere did you see any reference to a `send_data` method? Why did you think that would work? It looks like it came from something that's sending email? You have your CSV data in `csv_data`; what do you want to do with it? If you want it in a file, open a file and write to it.

    3. COAh, of course, I should have known - an ActionSomething method. Thank you, Rails, the double-edged sword of Ruby.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
