How to override plone.app.discussion's comments viewlet
================================================================================
Override the comments template through-the web
----------------------------------------------
* go to the ZMI
* click on portal_view_customizations
* customize plone.comments (plone.app.discussion.interfaces.IDiscussionLayer)
Override the comments template with z3c.jbot on the file system
---------------------------------------------------------------
http://pypi.python.org/pypi/z3c.jbot
setup.py::
install_requires=[
...
'z3c.jbot',
],
configure.zcml::
<include package="z3c.jbot" file="meta.zcml" />
<browser:jbot
directory="overrides"
layer="<layer>" />
Replace <layer> with a custom browserlayer of your package.
Create template directory::
$ mkdir overrides
Copy comments viewlet template to overrides directory::
$ cp ../parts/omelette/plone/app/discussion/browser/comments.pt overrides/plone.app.discussion.browser.comments.pt
Restart your Plone instance and you can start to customize your copy of the comments viewlet.
