Re: The state of Rails 2.3 / Engines migrations

seth b. — 2010-08-27T01:26:11

That does help and I think I'll go with that.

I've found you can run rake db:migrate:plugin NAME=pluginname and it 
runs fine.

The only issue I can't seem to solve is how to back out migrations 
applied in this way. Have you any guidance there?

Doesn't look like there's any sort of rake db:migrate:plugin:down 
...wondering if there should be?

Re: Engine routes

Matthew Crouch — 2010-08-01T16:04:57

Hi Michael,

Try using this instead:

Rails::Application.routes.draw do

I am using this with RC1 and get no warnings.

Cheers

Matt

Engine routes

Michael Rigart — 2010-08-01T15:51:39

Hi all,

I have a small question regarding Rails 3 / engines en routes file.

At this point, I start my routes file with the following line:

Rails.application.routes.draw do |map|

But, since Rails 3 RC 1, I got deprecation warnings in my app saying
that Rails.application will become deprecated, using
ProjectName::Application instead, but also that you need to drop the
|map| parameter.


Now, that is in a project, but what about engines? Since engines are
small sub applications that can be used in multiple apps, you can't just
use Projectname::Application.

Any comments on this issue?

Michael Rigart — 2010-07-31T17:54:28

thx, just got it ;). stupid question . Thx for the hint though. My 
earlier solution broke down when upgrading from Beta4 to RC1

Re: Rails 3 Engines

Matthew Crouch — 2010-07-31T17:46:10

This goes in your main engines class:

module SomeModule
  class SomeClass < ::Rails::Engine
    initializer 'some_class.helper' do |app|
      ActionView::Base.send :include, SomeHelper
    end
  end
end

Cheers

Matt

Hi Matt,

where exactly do you put that initializer?

Re: Rails 3 Engines

Didier Did — 2010-06-17T12:36:35

Thanks ! Same thing :-)

Re: Rails 3 Engines

Didier Did — 2010-06-17T11:11:53

That's right but how can your engine know what helpers are not tied to 
controllers ? mmmhh, that's definitely doable but it's not worth it.


I think that's because of namespacing. It expects Admin::MediasHelper 
but that's weird since you call it from your Admin module.
Maybe you should try to force it ?

ActionController::Base.helper "admin/#{File.basename(file, '.rb')
".camelize.constantize

I'm thinking, maybe you could have the best of the two worlds.

%w{metas categories themes}.each do |name|
  ActionController::Base.helper 
"Admin::#{name.camelize}Helper".constantize
end

What do you think about it ?

Re: Rails 3 Engines

Didier Did — 2010-06-17T10:18:52

Your solution looks good ! Are you sure that even your first statement 
(ActiveSupport::Dependencies.load_paths...) is needed ?



Something like that ?

module Admin
  # adjust path
  Dir[File.dirname(__FILE__) + "/../../helpers/**/*_helper.rb"].each do
|file|
     ActionController::Base.helper File.basename(file, 
'.rb').classify.constantize
  end
end

Re: Rails 3 Engines

Didier Did — 2010-06-17T09:20:30

I spent some much time on this, trying all the different ways of 
including those helpers (ie not related to controllers), without any 
success (sometimes it worked in dev env but not in prod, ...etc).
So I came up with another approach.
Actually, my engine controllers inherit from a base controller. So 
inside this base one, I added the following lines:

Dir[File.dirname(__FILE__) + "/../../helpers/**/*_helper.rb"].each do 
|file|
   helper "admin/#{File.basename(file, '.rb').gsub(/_helper$/, '')}"
end

Even if it is not super clean, it does the trick for me. If anyone has a 
better way of doing it, let me know :-)



Take a look at my generator:

This really isn't an Engines related question. You should probably be
be asking this on the general Rails forum;
rubyonrails-talk-/JYPxA39Uh5TLH3MbocFFw< at >public.gmane.org

When you post there, please include the code that is erroring and the
full error message - including stack trace. Without seeing the actual
code, it is nearly impossible to determain the cause of the error in
enough detail to explain it.

Re: fixnum problem

Manish Belsare — 2010-03-07T19:12:11

sir even if i try to call a method with a different name in the same 
Model file than also i get the same Finxum problem..

 I want to know what does that error mean?

Re: fixnum problem

Quoting manish belsare <manishbelsare2003-Re5JQEeQqe8AvxtiuMwx3w< at >public.gmane.org>:

Sounds to me like you have nothing (nil) when you expect something
(perhaps the integer?). Does your method then try to do some sort of
comparison, for example:
  if myparam > 3

If myparam is nil for some reason, you might get that error. Try
logging your input just after you get into the method. You may also
want to log its class (e.g. myparam.class).
