The state of Rails 2.3 / Engines migrations

seth b — 2010-02-09T21:43:01

Hey everyone,

I've been out of the loop for a minute regarding engines, but I'm
looking to update Substruct to Engines 2.3/Rails 2.3 if possible.

My last investigation stopped when running into the migrations issue.
I'm wondering if there is a recommended way to handle engine
migrations / legacy migrations (001_my_migration.rb) with 2.3. The
official site mentions some "things being in the works" but I didn't
really see anything past that.

Any advice or a link to a blog post would be cool. Thanks much.

ApplicationHelper in engine?

Jonathan Rochkind — 2009-09-14T16:22:22

So if I understand things right, my Engine plug-in can have a helper in 
it. And my app can provide a helper by the same name, and the two 
helpers will be merged together, any conflicting method names my app's 
helper with the same name will take precedence.

Is there a reason this wouldn't work for an ApplicationHelper in 
application_helper.rb ?

My engine provides an ApplicationHelper. That works fine as long as the 
app using it has no ApplicationHelper. But if the containing app does 
have an ApplicationHelper, they are NOT merged together, but instead 
only the containing app's ApplicationHelper is used, everything in the 
Engine's ApplicationHelper is lost and unavailable.

Can anyone shed some light on this?

Jonathan

relative_url_root in Engines::RailsExtensions::AssetHelpers.plugin_asset_path

John Koleszar — 2009-08-11T15:09:03

Hi,

I have a rails app (redmine) running within a sub-uri via the following
directive in environment.rb:

ActionController::AbstractRequest.relative_url_root = "/redmine" 

Unfortunately, URLs generated for plugin assets by Engines do not honor
this directive. I don't know Rails, but it seems like an easy fix if you
know how to get at the request object from within Engines. I was
thinking of something along these lines:

===================================================================
--- vendor/plugins/engines/lib/engines/rails_extensions/asset_helpers.rb
(revision 2796)
+++ vendor/plugins/engines/lib/engines/rails_extensions/asset_helpers.rb
(working copy)
< at >< at > -109,5 +109,5 < at >< at >
   # Returns the publicly-addressable relative URI for the given asset,
type and plugin
   def self.plugin_asset_path(plugin_name, type, asset)
     raise "No plugin called '#{plugin_name}' - please use the full name
of a loaded plugin." if Engines.plugins[plugin_name].nil?
-
"/#{Engines.plugins[plugin_name].public_asset_directory}/#{type}/#{asset}"
+
"#{< at >controller.request.relative_url_root}/#{Engines.plugins[plugin_name].public_asset_directory}/#{type}/#{asset}"
   end

Can someone point me in the right direction?

Thanks,

John
