    <p>I am trying to create a one-field form with a button. The field will be where the user enters his username. The value of that field will be passed into the variable <code>@username</code> in the following code:</p> <pre><code>def home require 'open-uri' @username = "brink" @url = "http://hiscore.runescape.com/index_lite.ws?player=#{@username}" end </code></pre> <p>As you can see, the <code>@username</code> variable is hard coded. I want to allow the user to input what he would like his username to be.</p> <p>After that, the user should be redirected to a page where he can see the results of his search.</p> <p>How would I implement such a feature? Not quite sure where to begin. What documentation can I look at to find help for this?</p> <p><strong>What I've looked into/Comments</strong></p> <ol> <li>I read up that forms essentially send POST requests. To my current understanding, I don't need a post request. All I need to do is take what the user specifies and substitute it into the URL</li> <li><p>Following Rich Peck's suggestion, I have created a new Search controller with a home action. Then I added <code>get "search(/:username)", :to =&gt; "search#home"</code> to my routes.</p> <p>This is great because it makes it possible to type in <strong>any</strong> username into the browser and be returned a table of information. The problem, now, is that <strong>regardless of the username I type in the browser</strong>, the username that gets passed into the crawler is still the one that is hard coded into my controller (in this case, Brink).</p> <p>What I am looking for is a way to submit a form that will cause the<code>@username</code> value to change accordingly. At the very least, we should be able to change the link up in the browser manually and achieve the same result.</p></li> <li>Removing <code>@username = "brink"</code> from my controller does not work.</li> <li><p>Here is the form I've created:</p> <pre><code>&lt;%= form_tag("/search", method: "get") do %&gt; &lt;%= label_tag(:q, "Search for:") %&gt; &lt;%= text_field_tag(:q) %&gt; &lt;%= submit_tag("Search") %&gt; &lt;% end %&gt; </code></pre> <p>When I submit it, it runs the code with the hardcoded <code>@username</code> value. This has me thinking, though. Will every form I create in this application do the same thing?</p></li> <li>I've pretty much gone blank. I feel so close, yet so far away. Haha. This is killing me! Guess I'll do some reading on routes and forms to see if it gets me closer to solving this problem. </li> </ol>

    1. CODo you need to do some work within your Rails app before redirecting or is “sending the user to a page where he can see the results of his search” is all that needs to happen?

    2. COSome work needs to be done. The page the user has to be redirected to is one that's in my application. I crawled the `@url`. The user should be redirected to a page in my application that displays the contents of `@url` with his username used.

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.
