The aim is to have an editor in which content is edited semantically, and both column layout and styling are applied separately. However, in the database only the combined HTML is stored. So, we have the following requirements:

HTML content is stored in the database something like:

<div class="row columns2">
<div class="column">
<h1 class="fancy">Heading</h1> <p class="note bordered">Some text</p>

</div> <div class="column">

<p>Some more text</p>



This is loaded into a custom editor in the browser which then immediately does some AJAX calls to the server to decompose into simplified HTML:

<h1 id="h1_1">Heading</h1> <p id="p_1">Some text</p> <p id='p_2'>Some more text</p>

and an array of objects specifying presentation e.g.

{'h1_1': ['fancy']}, # styles for the H1 {'p_1': ['note', 'bordered']}, # styles for the P {'newrow_h1_1': 'newrow' }, # specifies row before h1_1 {'newrow_p_2': 'newcolum' },


These two parts are then edited separately, i.e. the user does not see the combined HTML while editing. Before saving to the database, the editor does an AJAX call to combine the two parts. Note the use of the 'id' attributes are added to help identify what the styling information belongs to -- these will be removed before saving in the database.

Depending on the GUI for editing the presentation info, the user may have to press a 'refresh' button so that they can assign presentation info to newly entered paragraphs and headings etc. Newly entered paragraphs and headings will obviously not have the 'id' attributes, so the HTML may have to be updated at this point as well, so everything has an id.

WYMeditor extensions

The semantic editor application provides its own version of WYMeditor. This is derived from the skins/templates found in django-cms2, with the following customisations:

  • name of the skin changed from 'django' to 'semanticeditor'. This is necessary if we are to allow two different versions of WYMeditor on the same page, one using the normal WYMeditor + CMS controls, another with the full 'semantic editor' controls, for longer pieces of content.

  • The skin.js file removes the 'classes' panel, since this is not needed and is replaced by dynamic elements.

  • skins.css - added styling for additional presentation controls

  • a WYMeditor plugin named 'semantic' has been added. This implements most of the client side logic for this application.

  • the editorwidget.html template has been changed. In particular - the skin has been changed to 'semanticeditor' - a call to wymeditor.semantic() has been added to set up the plugin.

  • a new django widget 'SemanticEditor' has been created that inherits from the django 'WYMEditor' widget in django-cms2. This is needed so that

    • the WYMeditor 'semantic' plugin javascript file can be added to Media
    • our editorwdiget.html template can be used.
