    <p>I'm pretty new at rails, so forgive me if I'm overlooking simple things or the rails way. My objective is to completely replace URLs of the form </p> <p><code>/users/1</code></p> <p>with</p> <p><code>/username</code></p> <p>for all purposes. (I think exposing IDs scaffolding publicly is like walking around with a bone sticking out of your arm.) But implementing seems a little more complicated than I expected. This seems to change the entire way rails indexes and looks up users, rather than just substituting a lookup method.</p> <p>Although I've kind of gotten this to function using the <code>to_param</code> override in my <code>user.rb</code> file, I've read this means I'll have <a href="http://apidock.com/rails/ActiveRecord/Base/to_param" rel="nofollow noreferrer">indexing</a> <a href="http://blog.nhocki.com/2012/01/22/beautiful-urls-in-rails-the-easy-way" rel="nofollow noreferrer">problems</a> <a href="https://stackoverflow.com/questions/5611649/ruby-on-rails-routing-matching-username">down</a> the road when using <code>params([:username])</code>, and I'm not sure how it will impact my </p> <p>(a) session model at new user creation, and </p> <p>(b) @User usage in the user/show.html.erb file.</p> <p>So, I've either consulted the following pages (or asked the questions):</p> <ul> <li><a href="https://stackoverflow.com/questions/5611649/ruby-on-rails-routing-matching-username">Ruby on rails routing matching username</a></li> <li><a href="https://stackoverflow.com/questions/2269885/username-in-url-with-rails-routes">customize rails url with username</a></li> <li><a href="https://stackoverflow.com/questions/11048063/routing-in-rails-making-the-username-an-url">Routing in Rails making the Username an URL:</a></li> <li><a href="https://stackoverflow.com/questions/5204057/routing-error-with-username-in-url">routing error with :username in url</a></li> <li><a href="https://stackoverflow.com/questions/11514723/correct-routing-for-short-url-by-username-in-rails/11514977#comment15244810_11514977">Correct routing for short url by username in Rails</a></li> <li><a href="https://stackoverflow.com/questions/6461814/rails3-clean-url-friendly-id-sessions">rails3, clean url, friendly_id, sessions</a></li> </ul> <p>The major issues I'd like to understand from this question:</p> <ol> <li>What functionality do I lose by transitioning to this? That is, what things currently "just work" in rails that I'll have to address and rewrite if I pursue this replacement?</li> <li>As a practice, is this something better to replace with <a href="http://railscasts.com/episodes/314-pretty-urls-with-friendlyid" rel="nofollow noreferrer">friendly_id</a>? My concern here is that creating a slug column in my DB identical to the username seems a little non-DRY and makes me uncomfortable, and I'd rather avoid dependencies on external gems where possible.</li> <li>What does my users#show need to look like?</li> </ol>

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).
