Replace some code of the Plone collection portlet to add links color

Project Description


Change the renderer of your Plone collection portlet, trying to force a link color using a style="color: ..." attribute.

How to use

This product is for developers. It only add a catalog column (color) and change the basic Collection Plone renderer to check for this color.

Installing this won’t add any real new colors in collection portlets (and we don’t want … normally color must came from site UI theme, not contents).

How support colors

You can:

Support for a color property
Add to your content types a new color method or property.
Support for a color @indexer

Add an indexer that return the color you want:

>>> from plone.indexer.decorator import indexer
>>> @indexer(IMyType)
>>>     def color(object, **kw):
...     return 'red'

See Custom indexing strategies on Plone documentation section.

The color format must be CSS valid. So: ‘red’, ‘#FF0000’, ‘#F00’ or ‘rgb(255,0,0)’ are all good values.

If you return a string that starts with ‘class-‘ (like ‘class-foo’), this doesn’t apply the style attribute but a class="foo" attribute.

  • Fixed portletRenderer customization. Now is registered with the class (Assignment) and not with the interface (ICollectionPortlet).
