and plugins inside engines
It seems that plugins inside a Rails 3.1 application proper (i.e. in
/vendor/plugins) are initialized before engines and plugins inside
engines.
After some debugging, I found the culprit in
Rails::Application::Railties#all:
def all(&block)
@all ||= railties + engines + super
@all.each(&block) if block
@all
end
The call to super here implicitly passes the &block argument, which
has the unfortunate side-effect of adding the plugin initializers
first (in front of other railties and engines) in the case of
Rails::Engine#initializers:
def initializers
initializers = []
railties.all { |r| initializers += r.initializers }
initializers += super
initializers
end
The solution here is to replace the super call with a call
to #plugins.
