    <p>I just discovered the <a href="https://stackoverflow.com/questions/1092376/what-c-knowledge-should-i-have">what c# knowledge should I have?</a> question and wondered about the same, but for Ruby. I consider Ruby to be my favorite programming language, and beyond learning the basics, at least what I've picked up from numerous Ruby on Rails projects and a few Ruby scripts, I've tried to learn from reading blogs like <a href="http://feeds.feedburner.com/Gluttonous" rel="nofollow noreferrer">Gluttonous</a>, <a href="http://feeds.oreilly.com/oreilly/ruby" rel="nofollow noreferrer">O'Reilly Ruby</a>, <a href="http://feeds2.feedburner.com/olabini" rel="nofollow noreferrer">Ola Bini</a>, and <a href="http://blog.zenspider.com/atom.xml" rel="nofollow noreferrer">Polishing Ruby</a>. I've also read in books like <a href="http://rads.stackoverflow.com/amzn/click/0672328844" rel="nofollow noreferrer">The Ruby Way</a>.</p> <p>However, I haven't felt fully prepared when being interviewed about my Ruby skills. I was asked once if I knew about closures and at first I responded that I didn't, but then I asked if the interviewer meant code blocks, like lambda and <code>do</code>...<code>end</code>, and he did. How did I go about 3 years of programming Ruby and trying to learn the language without learning that closures = code blocks?</p> <p>So, my question to you is what knowledge should a Ruby programmer have of the Ruby language? What would you expect, as an interviewer for a Ruby position, me to know? Just list some topics, and I'll do the reading about them. Listing Ruby-specific tools like Ruby on Rails, Rake, Rack, etc. is good too, if you think that's necessary.</p>

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.
