    <p>I want to use jquery-rails to check if a email exists in my database. But I can't get jquery set up right into my rails application. My form looks like this :</p> <pre><code>&lt;%= form_for @user, :html =&gt; {:class =&gt; "col-md-10 center-margin"} do |f| %&gt; &lt;div class="form-row"&gt; &lt;div class="form-label col-md-2"&gt; &lt;label for=""&gt; Email: &lt;span class="required"&gt;*&lt;/span&gt; &lt;/label&gt; &lt;/div&gt; &lt;div class="form-input col-md-10"&gt; &lt;%= f.text_field :email, type: 'text', data: {trigger: "change"}, data: {required: "true" }, class: "parsley-validated", id: "user_email" %&gt; &lt;/div&gt; &lt;/div&gt; &lt;%= f.submit %&gt; &lt;/div&gt; &lt;% end %&gt; </code></pre> <p>In my application.js I have the following code:</p> <pre><code>$("#user_email").change(function(){ $("#user_email").append("&lt;p&gt;Test&lt;/p&gt;"); }); </code></pre> <p>When I start typing in the email field I would think test gets appended but nothing happens. What am I doing wrong?</p> <p>in my application.html.erb I have :</p> <pre><code>&lt;%= javascript_include_tag "application" %&gt; &lt;%= javascript_include_tag "jquery-rails.js" %&gt; </code></pre> <p>Edit:</p> <p>This is how my application.js looks like </p> <pre><code>// This is a manifest file that'll be compiled into application.js, which will include all the files // listed below. // // Any JavaScript/Coffee file within this directory, lib/assets/javascripts, vendor/assets/javascripts, // or vendor/assets/javascripts of plugins, if any, can be referenced here using a relative path. // // It's not advisable to add code directly here, but if you do, it'll appear at the bottom of the // compiled file. // // Read Sprockets README (https://github.com/sstephenson/sprockets#sprockets-directives) for details // about supported directives. // //= require jquery //= require jquery_ujs //= require turbolinks //= require_tree . //= require bootstrap $( document ).ready(function() { $("#user_email").change(function(){ var currentVal = $("#user_email").val(); $("#user_email").val(currentVal + " Test"); }); }); </code></pre>

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.
