    <p>Use Ruby method, <code>sleep</code></p> <pre class="lang-rb prettyprint-override"><code>seconds_to_delay = 5 sleep seconds_to_delay </code></pre> <hr> <p>Edit 1: Dealing with divs that load some time after the document finishes loading</p> <p>I hate this scenario. I had to deal with exact same scenario, so here's how I solved it. You need to use something like <a href="http://rubygems.org/gems/selenium-webdriver" rel="nofollow">selenium-webdriver</a> gem.</p> <pre class="lang-rb prettyprint-override"><code>require 'selenium-webdriver' url = "http://techcrunch.com/search/education#stq=education&amp;stp=1" css_selector = ".tab-panel.active" driver = Selenium::WebDriver.for :firefox driver.get(url) driver.switch_to.default_content posts_text = driver.find_element(:css, css_selector).text puts posts_text driver.quit </code></pre> <p>If you are running this on some virtual machine on Heroku, AWS EC2 or Digital Ocean and stuff, you can't use firefox. Instead you need a headless browser like phantom.js.</p> <p>In order to use phantom.js instead of firefox, first, install phantomjs on the VM. Then change to <code>driver = Selenium::WebDriver.for :phantomjs</code>.</p> <p>You can use <a href="https://rubygems.org/gems/phantomjs" rel="nofollow">this gem</a> that actually installs phantomjs for you.</p> <hr> <p>Second edit for question b)</p> <pre class="lang-rb prettyprint-override"><code>require 'selenium-webdriver' url = "http://techcrunch.com/search/education#stq=education&amp;stp=1" css_selector = ".tab-panel.active ul.river-compact.river-search li" driver = Selenium::WebDriver.for :phantomjs driver.get(url) driver.switch_to.default_content items = driver.find_elements(:css, css_selector) items.each {|x| puts x } driver.quit </code></pre>

    1. COThe problem is that the get request via Nokogiri gets an empty page, the contents of which is loaded by Javascript and appears after a few seconds. So I don't think this will help. Thanks for the method heads-up though, v interesting one

    3. COVery curious. It actually launches Firefox for you! Is there any way to a) not do that and b) loop through the <li> items as I would do in Nokogiri(doc.css('li').each {|link| puts link.content}) etc?

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
