|
|
================================================================================
|
|
|
|
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.
