Sorry if this is a complete newbish question, but I''m trying to wrap my head around creating custom classes in my rails webapp. I''m normally a Java developer, but I figured I''d give RoR a try and see how I like it, and whether it would be useful for production use with a new client. Anyways, what are the best practices for custom classes? Where and/or how do I create and use them? Is there a tutorial somewhere? Basically, here''s what I''m trying to do. I have an XML file in a custom format that represents news articles. In my controller I''m using REXML to read and parse that file (BTW, see my note at the end of this email), and I want to encapsulate that into an "Article" type class, with title, date, description, etc that I can then use in my view. How do I go about this? Where should I store the class? If someone could point me to a tutorial or example of custom classes in a Rails app, or give me a little hint how/where to start I''d really appreciate it. Thanks, - Brent NOTE: I was having a terrible time with RoR giving me a "File not found" error when calling File.new. It said the current directory was my rails project directory root. I checked, rechecked, copied-pasted the directory/file to make SURE it was there. It was! Turns out the current directory is the config/ directory and NOT the project one as reported.

If you''ve not read the Agile Web Development book, you really should.
YOu can define custom classes anywhere, really... *lib, vendor, etc.
However, what you have is definitely a model class... So create it in
the models folder.
App/models/article.rb
class Article
# class methods
def self.find()
# load a new article instance from the xml file based on the
conditions in the finder.
# maybe you have to return an array of these article objects
because you might find
# more than one.
end
def self.find_by_title
end
# instance methods
def title
'' return title
end
...
End
Then you can access it like any other model.
Please share what you create... It could be useful to others! Good luck!

Subject: [Rails] Newbie Question about Custom Classes
Sorry if this is a complete newbish question, but I''m trying to wrap my
head around creating custom classes in my rails webapp. I''m normally a
Java developer, but I figured I''d give RoR a try and see how I like it,
and whether it would be useful for production use with a new client.
Anyways, what are the best practices for custom classes? Where and/or
how do I create and use them? Is there a tutorial somewhere?
Basically, here''s what I''m trying to do. I have an XML file
in a custom
format that represents news articles. In my controller I''m using REXML
to read and parse that file (BTW, see my note at the end of this email),
and I want to encapsulate that into an "Article" type class, with
title,
date, description, etc that I can then use in my view.
How do I go about this? Where should I store the class? If someone
could point me to a tutorial or example of custom classes in a Rails
app, or give me a little hint how/where to start I''d really appreciate
it.
Thanks,
- Brent

Thanks for the response. I was just thinking of doing this. But here''s what I would normally do in Java. I''d create a News class, and an Article class. The News class would read the XML and create an array of Article classes. So, should I create two models, one called News and one called Articles? Is every custom class considered a model? What about some utility class that really doesn''t fit as a model?

Classes that have nothing to do with holding data, go into the lib directory. If your parsing logic is not too complex, i would put it into the Article class. If it is complex, put it as a separate class or module in lib. My suggestion for your Article class: class Article # class methods class < self def build_from_xml # parsing logic goes here returning an Array of Article objects end end end In your controller just do: class NewsController < ApplicationController def my_action File.open(''my_articles.xml'') do |file| @articles = Article.build_from_xml(file.read) end end end -- Norman Timmler http://blog.inlet-media.de
Thanks for the info! The parsing won''t be terribly complex (just doing some xpath queries, etc) so I think I''ll use your suggestion. In Java, for a class to be used it has to be in your classpath. How does RoR figure out where the actual class is? Does it look under your app/models (and controllers, views, etc) and lib directories?

I did a CMS framework for a newspaper in Java, using the Spring J2EE framework. There, I created an XML DAO layer, and then had XMLbean NewsML business objects instantiated by the controller accessing the DAO layer (which talked to an Xindice server!). (By the way, it''s been working in production for ages, stable as heck... WISH RAILS 1.0 HAD BEEN THERE THEN... took me months to develop, instead of the weeks it would have taken on Rails, not to mention some javascript sprite action that would have been a heck of a lot simpler!). The great thing about treating the persistent XML (whether files, a server like XIndice, etc.) as a data access layer meant that if later I decided to use MySQL or Berkeley XML database, I would only have to modify that layer. Now... On Rails, just simply have your controller instantiate a business object (a model class) that knows how to read/write XML from/to flat files. This can be by invoking a library, or, to get more sophisticated, by writing a data access adapter for flat XML files (ActiveRecord/ConnectionAdapters) (my Rails ignorance prevents me from knowing whether this already exists as a third party; the API doesn''t mention any). Hope that helps.

It is extended by Rails (1.0) using the following method: def default_load_paths paths = ["#{root_path}/test/mocks/#{environment}"] # Then model subdirectories. # TODO: Don''t include .rb models as load paths paths.concat(Dir["#{root_path}/app/models/[_a-z]*"]) paths.concat(Dir["#{root_path}/components/[_a-z]*"]) # Followed by the standard includes. # TODO: Don''t include dirs for frameworks that are not used paths.concat %w( app app/models app/controllers app/helpers app/services app/apis components config lib vendor vendor/rails/railties vendor/rails/railties/lib vendor/rails/actionpack/lib vendor/rails/activesupport/lib vendor/rails/activerecord/lib vendor/rails/actionmailer/lib vendor/rails/actionwebservice/lib ).map { |dir| "#{root_path}/#{dir}" }.select { |dir| File.directory?(dir) } end Files in this directories don''t have to be required explicitly (because of some Ruby extensions made by rails), but files in subdirectories of you loadpath, e.g. lib/my_library/myfile.rb must be required like this: require ''my_library/myfile'' -- Norman Timmler http://blog.inlet-media.de
Alright, I know I have to be doing something extremely noobish. But
I''ve created a simple class that has one method just as a test,
because RoR can''t seem to find the methods I put in the class. So
here''s the simplest example I could think of:
class Article
def blah
end
end
Yes, this does absolutely nothing. But if I try this in my controller:
Article.blah()
I get "undefined method `blah'' for
#<Article:0xb789bfbc>". It doesn''t
matter what I put into "blah" it just never sees it. It does,
however, see the article class. Do I have to do anything special, or
define the method another way so that it''s accessible from the
controller? It''s currently in app/models/article.rb.
Thanks,
- Brent

OK, here''s the deal. It turns out I''ve got some caching turned on or something. I bounced Apache HTTPD and wham, it worked. I then added a return to my blah function to return a string. I tried again and it wasnt returning anything. I bounced the server again and it returned the value I set. Seems as though it gets cached the first time it runs then never changes again.

Brent: You say you''re using Apache? Why not use WEBrick? The reason I ask is that if you are using Apache + FCGI and you are in "Production" mode, all models will be cached.

It''s located in app/models. I was thinking it may be running in the production environment, because there is a setting called "config.cache_classes" which was set to true.

Well, personally, I like developing, testing and pushing the same files in the same environment. So if the production server is apache, then I develop with the same. But, if there are known issues I could always switch to WEBrick for development, and leave Apache for production.

It''s the beauty of Rails.... You can develop on WEBRICK and SQLite and deploy to Apache + MySQL or Lighttpd + Oracle without worrying about anything breaking.

Well one problem I may have is name based virtual hosting. If I have two or more projects in development at the same time, using apache I can just use name based virtual hosting on our dev server and have one web server serving two different sites (which is how we also do it in production). But if I use WEBrick for development, will I have to load two instances of it on different ports? Thanks, - Brent On 3/20/06, Hogan, Brian P. <HOGANBP@uwec.edu> wrote:> It''s the beauty of Rails....

OK, even using WEBrick the class gets cached. The caching is all set to false under config/environments, is there something I''m missing? - Brent On 3/20/06, Hogan, Brian P. <HOGANBP@uwec.edu> wrote:> It''s the beauty of Rails....

Yes you would run two WEBrick servers on different ports. I guess I''ve never run into a situation on my local machine where that''s been an issue; if I need that, then I deploy to staging. Whatever works for you! As for your caching... I''m baffled.

If there''s some weirdness when it moves from development to staging then I''ll deal with it then. I think it''ll be fine though.> As for your caching... I''m baffled. Perhaps you have the environment set > to production in the environment file?The only thing uncommented out in environment.rb is: require File.join(File.dirname(__FILE__), ''boot'') Rails::Initializer.run do |config| end That''s it. And here is what''s uncommented in the environment files: development.rb ---------------- config.cache_classes = false config.whiny_nils = true config.breakpoint_server = true config.action_controller.consider_all_requests_local = true config.action_controller.perform_caching = false config.action_mailer.raise_delivery_errors = false test.rb -------- (all the same as above except the last line) config.action_mailer.delivery_method = :test production.rb --------------- config.cache_classes = false config.action_controller.consider_all_requests_local = false config.action_controller.perform_caching = false And that''s it. But it still insists on caching the class when I change it. Here''s the kicker, I can change the controller all day long and it doesn''t cache it. So, for example, my "blah" method just returns a static string, I then set @page_title to what it returns before it''s handed off to my layout, partials and view. If I change what article.rb returns it doesn''t change (appears to be cached), BUT if I change the controller and just append "BRENT" to what it returns, THAT change appears but the text that prepends that is still the old cached string from the blah call. It''s driving me nuts. I''m definitely NOT going to restart the server after every little change to a class. Thanks, - Brent
Alright I just ran into something that''s exactly what I''m
talking
about when I say a difference in environment by not using the same
webserver.
I switched to WEBrick and a piece of my code stopped working. When I
make this call:
file = File.new("public/news.xml")
It works fine using WEBrick, because the rails root is the current
working directory. HOWEVER, under Apache this is not the case. Rails
REPORTS that the root is the cwd, even in the file not found error,
but I went crazy trying to figure out why it couldn''t find it because
I knew it was there.
Turns out when running under Apache, the cwd is in a subdirectory of
the root. If I had to guess I''d say the cwd was the "config"
directory and not the actual rails root. So my code was set to look
for it in "../public/news.xml" and that worked perfectly fine. As
soon as I switch to WEBrick, bang, error. Anyone else use Apache and
notice this?

Yep, the filename of the Article model is app/models/article.rb. I''m still trying to figure out why it''s being cached under WEBrick and Apache both.
