    <p><a href="http://github.com/kevinclark/dust/tree/master" rel="nofollow noreferrer">Dust</a> looks like it can help you find unused and useless code, which seems like it sort-of fits what you're after.</p> <p>I'm not aware of any other such tools.<br> This problem is vastly harder to address in ruby than it is in java - you'll note that all those java tools brand themselves as using 'static analysis' of the code.<br> Static analysis of ruby code often isn't possible, because there isn't anything static that you can analyze (methods often get created at runtime and so on)</p> <p>At any rate, some of these things are unneeded in ruby because the language builds them in. For example, you don't need a coding standard to enforce that your classes are all <code>NamedLikeThis</code> because the code won't work if they aren't.</p> <p>P.S. I <em>have</em> to add the standard disclaimer that those kind of tools can often be a bit of a red herring. You can spend all day making your code adhere to what the tool thinks it should be, and end up with more bugs than you started with.<br> IMHO the best solution is to write your code fluently so you can read it more easily. No amount of static analysis is going to be as good as a human reading code which clearly states what it is meant to do. Being able to do this is where ruby is light-years ahead of many other languages. I personally would recommend you aim your efforts at learning how to write more fluently, and educating your team about such things, than spending time on static analysis.</p>

    1. COWriting fluently and educating the team is certainly a goal; however, when idioms change (for example ENV['RAILS_ENV'] == 'development' to Rails.env.development?) then these kinds of tools can be very helpful in preventing bad habits from getting a start.

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.

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