To a certain degree you can replace/extend logic in existing classes. This might be an option to extend the bundled plugin. You would write a new plugin which just add the modified logic. Using module prepend.
enabled_site_setting :myoverridingplugin_enabled
module ::MyOverridingPlugin
PLUGIN_NAME = "my-overriding-plugin"
class Engine < ::Rails::Engine
engine_name MyOverridingPlugin::PLUGIN_NAME
isolate_namespace MyOverridingPlugin
end
module SomeClassOverrides
def overriding_method(foo, bar)
if foo == "something"
# do something custom
else
# this will call the original logic
super(f00, bar)
end
end
end
end
after_initialize do
SomeClass.prepend(MyOverridingPlugin::SomeClassOverrides)
end
I used this constructor to limit some controllers under certain conditions.
