Yes, but I *was* using a to_prepare block (w/o actually understanding
what it does, though.)
So what I now actually have in init.rb is this:
Dispatcher.to_prepare :redmine_model_dependencies do
puts "!!! to_prepare block !!!"
require_dependency 'application_helper'
unless ApplicationHelper.included_modules.include?
RedminePastebin::ApplicationHelperPatch
ApplicationHelper.send(:include,
RedminePastebin::ApplicationHelperPatch)
end
end
If I put some logging lines into redmine's application_helper.rb, I
can get this:
module ApplicationHelper
def self.included(base)
puts "ApplicationHelper: INCLUDED: #{self.method_defined?
(:parse_redmine_links_with_pastes)}"
end
...
def parse_redmine_links(text, project, obj, attr, only_path,
options)
logger.info "parse_redmine_links"
...
And in my patch-module I have this log line:
def parse_redmine_links_with_pastes(text, project, obj, attr,
only_path,
options)
logger.info "parse_redmine_links_with_pastes"
...
Now for the first page load I get these:
ApplicationHelper: INCLUDED: false
ApplicationHelper: INCLUDED: false
!!! to_prepare block !!!
=> Call with -d to detach
=> Ctrl-C to shutdown server
!!! to_prepare block !!!
ApplicationHelper: INCLUDED: true
...
parse_redmine_links_with_pastes
...
and for the second load, these:
!!! to_prepare block !!!
ApplicationHelper: INCLUDED: true
ApplicationHelper: INCLUDED: true
ApplicationHelper: INCLUDED: true
...
parse_redmine_links
So original unmodified method is called regardless of the fact that
the new one is defined...
I guess I need to move that alias_method_chain call somewhere else so
it's called on every page load. How do I do so?
