title: How to use placeholders outside django-CMS?
body: <p>I'm trying to implement the documentation on django-cms on <a href="http://docs.django-cms.org/en/latest/how_to/placeholders.html#how-to-use-placeholders-outside-the-cms" rel="nofollow noreferrer">How to use placeholders outside the CMS</a></p>
  <p>It seems possible to define a field in a model app external to the CMS which will behave like the <a href="https://pypi.org/project/djangocms-text-ckeditor/" rel="nofollow noreferrer">djangocms-text-ckeditor</a></p>
  <p>But I can't get this 'templatetag' to work</p>
  <pre class="lang-html prettyprint-override"><code>{% extends 'base.html' %}
  {% load cms_tags %}
  
  {% block content %}
      &lt;h1&gt;Title page info&lt;/h1&gt;
      {% render_placeholder object.short_text &quot;640&quot; %}
  {% endblock content %}
  </code></pre>
  <p>Here my info.models.py</p>
  <pre class="lang-py prettyprint-override"><code>from django.db import models
  from cms.models.fields import PlaceholderField
  
  class MsgDet(models.Model):
      title = models.CharField(max_length=255)
      short_text = PlaceholderField('content')
  </code></pre>
  <p>I've create a small django-cms project following the django-cms tutorail using <a href="http://docs.django-cms.org/en/latest/introduction/01-install.html" rel="nofollow noreferrer">django CMS installer</a>. The source code is on GitHub under <a href="https://github.com/openHBP/PlaceholderField" rel="nofollow noreferrer">OpenHBP/PlaceholderField</a>. I've added a simple info app to the cms and I try to display &quot;MsgDet.short_text&quot; fields inside a &quot;CKEditor like&quot; plugin.</p>
  <p>A double-click on the CMS home page opens a CKeditor window. I would like to achieve the same result on my info page!</p>
  <p>I know this can be achieved by using <em>RichTextField</em> from <em>ckeditor</em> but I would like to use &quot;PlaceHolderFiled&quot; in order to have access to djangoCMS plugins: picture/image or file.</p>
  <p>Note that I've also tried with <a href="https://github.com/nephila/django-ckeditor-filebrowser-filer" rel="nofollow noreferrer">django-ckeditor-filebrowser-filer</a> but the project seems deprecated and pdf upload does not work.</p>
  <p><strong>I just want to be able to access filer files (images &amp; documents) from a &quot;CKEditor like&quot; window...</strong></p>
