[Rails] I can''t get rails to see my plugin. How can I this?

I''m trying to produce a plugin to help me with my page caching woes.  I
can''t seem to get rails to see my method within the plugin.  This is my
first attempt at a plugin so I''m sure I''m missing something. 
I''ve
created a directory /vendor/lib/plugins/broom_stick/.  I then created an 
init.rb file with:
require ''broom_stick''

I then created /vendor/lib/plugins/broom_stick/lib/broom_stick.rb
Here are the contents of broom_stick.rb.  It doesn''t add any new 
functionalit...yet.  I wanted to make sure I could get the plugin seen 
by rails before I did any real coding.  Thanks in advance for any 
assistance.

module ActionController::Caching::Pages::ClassMethods
  # Expires the page that was cached with the +path+ as a key. Example:
  #   expire_page "/lists/show"
  def expire_each_page(path)
    return unless perform_caching
    benchmaddrk "EXPIRED ALL PAGES: #{page_cache_file(path)}" do
    File.delete(page_cache_path(path)) if 
File.exists?(page_cache_path(path))
    Dir.foreach(page_cache_path(path)) {|x| benchmark ("Got " + x) }
    end
  end
end

The simplest possible thing, you do mean:

#{RAILS_ROOT}/vendor/lib/plugins/broom_stick/

right?

Hi Charlie,

I think your folder hierarchy is wrong:

vendor/plugins/broom_stick/init.rb
vendor/plugins/broom_stick/lib/broom_stick.rb

If you''ve got any doubt, the simplest thing to do is use the plugin  
generator to see how to properly layout a plugin:

(in your rails application root)

./script/generate plugin test_this

will show you where the files ought to go (you can remove vendor/ 
plugins/test_this afterwards).

Regards,
Trevor

Actually, the path was a typo.  I am using the
path: /vendor/plugins/broom_stick/.

Hi again Charlie,

you''ve got me wondering - you *do* realize that you''ve only
added
your method to the ClassMethods module (so it''s not a controller  
instance method) right?

So you have to use it like:

MyController.expire_each_page(somepath)

The code you posted really ought to work so trying to call a class  
method as though it was an instance method is about the only place I  
can think you''re going wrong.

HTH,
Trevor

[Rails] I can''t get rails to see my plugin. How can I this?

I didn''t.  I''m still trying hard to grasp the inner working of
rails and
ruby inheritance in general.  I have modified the plugin but it is still
breaking because it can''t find the page_cache_path and page_cache_file
methods.  Here''s what I''ve got so far.  Thank you for your
help so far!
 
module ActionController::Caching::Pages
  def expire_each_page(path)
    return unless perform_caching
    logger.error("EXPIRED ALL PAGES: #{path}")
    File.delete(page_cache_path(path)) if
File.exists?(page_cache_path(path))
    Dir.foreach(page_cache_path(path)) {|x| benchmark ("Got " + x) }
    rescue
  end
end

Hey again,

you can''t find page_cache_path and page_cache_file because they are  
*class* methods.

With the changes you sent your expire_each_page method is now an  
*instance* method (it''s no longer in the ClassMethods module).

So, change the calls to page_cache_path and page_cache_file to be  
self.class.page_cache_path and self.class.page_cache_file and see how  
you get on.

Regards,
Trevor

[Rails] I can''t get rails to see my plugin. How can I this?

Hi Charlie,

it would seem on my last email I steered you a bit wrong:  namely I  
forgot that page_cache_file and page_cache_path are private class  
methods so you can''t call them from an instance method.

Try this instead:

module ActionController::Caching::Pages
   module ClassMethods
     def expire_each_page(path)
       return unless perform_caching
       logger.error("EXPIRED ALL PAGES: #{path}")
       File.delete(page_cache_path(path)) if File.exists? 
(page_cache_path(path))
       Dir.foreach(page_cache_path(path)) {|x| benchmark ("Got " + x)
}
       rescue
     end
   end

   def expire_each_page(path)
     self.class.expire_each_page(path)
   end
end

Regards,
Trevor

[Rails] I can''t get rails to see my plugin. How can I this?

Thanks again for so much help! I think I''m getting much closer to
understanding this stuff.  It still isn''t quite there.  The app runs
and
rails doesn''t complain about not finding the methods, but I still
can''t
get the correct result out of the method.  Only the first logger.error
is printing to the log.  I added a two more logger statements and the
second statement won''t print.  I"m I missing something else as
well?

module ActionController::Caching::Pages
  # Expires the page that was cached with the +path+ as a key. Example:
expire_page "/lists/show"
  def expire_each_page(path)
    return unless perform_caching
    #test = self.class.page_cache_path(path)
    logger.error("EXPIRED ALL PAGES: #{path}")
    test = self.class.page_cache_path(path)
    logger.error("FULL PATH OF PAGES: #{test}")
    File.delete(self.class.page_cache_path(path)) if
File.exists?(self.class.page_cache_path(path))
    Dir.foreach(self.class.page_cache_path(path)) {|x| logger.error("Got
#{x}") }
    rescue
  end
end

[Rails] I can''t get rails to see my plugin. How can I this?

Thanks, your last tip really helped out!  My method ran correctly.  So
just to make sure I have this correct in my head, I''m adding a method
to
the ClassMethods module.  Then I''m creating a method of the same name
in
ActionController::Caching::Pages.  This second method calls the method
in the module ClassMethods?  Wow this stuff can be confusing!
