In my flask-app I'm using CKEditor. This is my configuration so far.
In my layout.html at the end of the body tag:
<script src="//cdn.ckeditor.com/4.6.2/full/ckeditor.js"></script>
<script type="text/javascript">CKEDITOR.replace('editor')</script>
Here in my articles.html is the mentioned id for it:
<form action="" method="POST">
<div class="form-group">
{{ render_field(form.body, class="form-control", id="editor") }}
</div>
<p><input type="submit" class="btn btn-primary" value="Submit"></p>
</form>
This is how I am getting content back from my database when I write content using CKEditor CDN.
Try this
<form action="" method="POST">
<div class="form-group">
{{ render_field(form.body, class="form-control", id="editor") | safe }}
</div>
<p><input type="submit" class="btn btn-primary" value="Submit"></p>
</form>
