<h1>Error: error:ctreq
  <div><span class='hint'>Missing Required Controller</span></div>
</h1>

</div>

<h2>Description</h2>
<div class="description">
  <p>This error occurs when <a href="api/ng/service/$compile">HTML compiler</a> tries to process a directive that specifies the <a href="api/ng/service/$compile#directive-definition-object"><code>require</code> option</a> in a <a href="api/ng/service/$compile#comprehensive-directive-api">directive definition</a>,
but the required directive controller is not present on the current DOM element (or its ancestor element, if <code>^</code> was specified).</p>
<p>To resolve this error ensure that there is no typo in the required controller name and that the required directive controller is present on the current element.</p>
<p>If the required controller is expected to be on a ancestor element, make sure that you prefix the controller name in the <code>require</code> definition with <code>^</code>.</p>
<p>If the required controller is optionally requested, use <code>?</code> or <code>^?</code> to specify that.</p>
<p>Example of a directive that requires <a href="api/ng/directive/ngModel">ngModel</a> controller:</p>
<pre><code>myApp.directive(&#39;myDirective&#39;, function() {
  return {
    require: &#39;ngModel&#39;,
    ...
  }
}
</code></pre>
<p>This directive can then be used as:</p>
<pre><code>&lt;input ng-model=&quot;some.path&quot; my-directive&gt;
</code></pre>
<p>Example of a directive that optionally requires a <a href="api/ng/directive/form">form</a> controller from an ancestor:</p>
<pre><code>myApp.directive(&#39;myDirective&#39;, function() {
  return {
    require: &#39;^?form&#39;,
    ...
  }
}
</code></pre>
<p>This directive can then be used as:</p>
<pre><code>&lt;form name=&quot;myForm&quot;&gt;
  &lt;div&gt;
    &lt;span my-directive&gt;&lt;/span&gt;
  &lt;/div&gt;
&lt;/form&gt;
</code></pre>
