Override the main_template.pt without z3c.jbot

Question

I want to override the original main_template of Plone without using z3c.jbot, only using ZCML directives (browser:page?).

Is there a way to override a default Plone4 template only using ZCML?

Answer 1

ZCML can be used to override views.

Older Plone templates, like main_template.pt, use portal_skins layering facilities.

More about it in here:

https://docs.plone.org/4/en/old-reference-manuals/plone_3_theming/buildingblocks/skin/layers/overview.html

• Your addon needs GenericSetup profile

• You register skin layers in GenericSetup XML

• You register skin layers in ZCML

• skin templates are overridden in the order given by portal_skins Properties tab (you can test and manage TTW after ZCML part is done)
