    <p>My question is very similar to <a href="https://stackoverflow.com/questions/695971/java-http-post-to-create-new-product-in-a-ruby-on-rails-application">Java: HTTP Post to create new &quot;Product&quot; in a Ruby on Rails application</a></p> <p>I have a form that I want to "post" to a form that looks like this</p> <pre><code>Offer:&lt;br /&gt; &lt;input id="ride_togive" name="ride[togive]" size="30" type="text" /&gt; &lt;/p&gt; &lt;p&gt; Request for Offer:&lt;br /&gt; &lt;input id="ride_totake" name="ride[totake]" size="30" type="text" /&gt; &lt;/p&gt; </code></pre> <p>My Java code looks like this</p> <pre><code>DefaultHttpClient client = new DefaultHttpClient(); HttpPost post = new HttpPost("http://172.16.60.129:3000/rides"); // Configure the form parameters List &lt;NameValuePair&gt; nvps = new ArrayList &lt;NameValuePair&gt;(); nvps.add(new BasicNameValuePair("ride_totake", "Ride to Vail")); nvps.add(new BasicNameValuePair("ride_togive", "$20")); post.addHeader("Content-Type","application/json"); try { post.setEntity(new UrlEncodedFormEntity(nvps, HTTP.UTF_8)); } catch (UnsupportedEncodingException e) { // TODO Auto-generated catch block e.printStackTrace(); } HttpResponse response = null; try { response = client.execute(post); } catch (ClientProtocolException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } HttpEntity entity = response.getEntity(); System.out.println("form get: " + response.getStatusLine()); if (entity != null) { try { entity.consumeContent(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } </code></pre> <p>Here is the output of the RoR console</p> <pre><code>Processing RidesController#create (for 172.16.60.1 at 2009-11-04 22:22:52) [POST] Parameters: {"_json"=&gt;"totake=Ride+to+Vail&amp;togive=%2420"} Ride Columns (0.6ms) SHOW FIELDS FROM `rides` SQL (0.1ms) BEGIN Ride Create (0.3ms) INSERT INTO `rides` (`isoffer`, `togive`, `howlong`, `updated_at`, `totake`, `created_at`) VALUES(NULL, NULL, 0, '2009-11-05 05:22:52', NULL, '2009-11-05 05:22:52') SQL (0.0ms) COMMIT Redirected to http://172.16.60.129:3000/rides Completed in 9ms (DB: 1) | 302 Found [http://172.16.60.129/rides] </code></pre> <p>I guess my real question is how should I be addressing the RoR variables in Java?</p>

    1. COI am not sure what you meant RoR variables, but when every thing is happening over HTTP POST or GET then all those values will be available in HTTP Response right?

    2. COWhat I mean by RoR variables is the html form that is generated by RoR that is at the top of my question. How do I insert values into those fields in java?

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).
