I use ENUM() columns in mysql - rails treats them as strings so
everything works (apart from schema dumps)
Sorry, I misunderstood the question, I assumed you wanted to know how to
store the country names in a countries table. I did not realise that in
option 1 you meant storing the string in every record that references
country, though that is what you said, I did not read it carefully. Now
that I understand, I would suggest some variant of option 2, store an id in
each record referencing a country and determine the string by an enumeration
or table lookup later. Worrying too much about computing time during
development is a mugs game, an application always ends up with most of its
computing time in an area you do not expect. Worry about optimisation later
when (or more likely if) a particular area becomes a problem.
Colin
Colin,
yes i guess 2nd variant will be better.

But Bilee,
if we use another table and do the mapping through foreign key won;t
it be even poorer as we will be making 2 SQL queries to access the

[Rails] STI and subclassing twice
I'm trying using STI to implement a hiearchy similar to this: script/generate scaffold name:string type:string class Person ActiveRecord::Base; end class Customer Person; end class Employee Person; end class Developer Employee; end I.e., there are two levels of inheritance (Developer Employee Person). When creating a Customer, Rails understands it's a Person, but if I create a Developer, Rails 'tends to forget' it's an Employee. In other words: $ script/console Developer.create :name='Bob' = #Developer id: 1, name: Bob, type: Developer, created_at: 2009-05-08 09:59:58, updated_at: 2009-05-08 09:59:58 exit $ script/console Employee.find :all = [] Person.find :all = [#Developer id: 1, name: Bob, type: Developer, created_at: 2009-05-08 09:59:58, updated_at: 2009-05-08 09:59:58] Worst of all, if I change the order of the 'find' statements, things work: $ script/console Person.find :all = [#Developer id: 1, name: Bob, type: Developer, created_at: 2009-05-08 09:59:58, updated_at: 2009-05-08 09:59:58] Employee.find :all = [#Developer id: 1, name: Bob, type: Developer, created_at: 2009-05-08 09:59:58, updated_at: 2009-05-08 09:59:58] Maybe this has to do with some caching stuff... any ideas? -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

Mike m...@asplake.co.ukhttp://positiveincline.comhttp://twitter.com/asplake Clients of RESTful web applications typically use prior knowledge of the target application’s structure to generate URIs. This approach is often very convenient, but much of this URI generation is hard-coded, and (worse) spread across client code. This introduces a high degree of coupling and makes clients unnecessarily vulnerable to server-side change. Steps to improve this situation: 1. In clients, centralise the generation of URIs and make the process driven by configuration data 2. Have servers publish the required configuration data - i.e. application metadata - in a readily understood format path-to provides the means for client applications to model web applications in terms of logical structure and URI mappings, and to interact with them through dynamically-generated application-specific APIs. described_routes supports an application metadata structure (published in JSON, YAML and XML formats) that can be consumed by path- to, and (helpfully) generates it automatically online or offline from the routes configured for a Rails-based application. The two libraries can be used separately or together - an JavaScript client is under independent development for example. Moreover, the underlying metadata format is framework-neutral; we have been careful not to “leak” Rails concepts into it. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

[Rails] jRails problem
Hi,
I am developing a Rails app and now I want to try some Ajax
funcionality. I have a tracks list, and each track has a delete button.
I have this operation implemented without Ajax with a redirection, and
now I want to do it with Ajax. I am using JQuery and jRails.
Here is my code:
This is the delete function in my controller:
def delete_track
@track_id = params[:track_id]
Track.delete(@track_id)
respond_to do |format|
format.html {redirect_to :action = 'index'}
format.js
end
This is my html where the tracks list is:
div id=musicalUnit
h3 id=musicalUnitTileEstado de su unidad musical:/h3
ol
%unless @musical_unit.nil? %
% for track in @musical_unit.tracks %
li id=track%= track.id %%= track.name % de strong%=
track.album.singer.name %/strong
%= link_to_remote(image_tag(delete.png, :alt = 'Borrar',
:size = 16x16, :title = Borrar + track.name + de mi unidad
musical),
:update = musicalUnitTile, :url = {:controller =
tracks, :action = 'delete_track', :track_id = track.id}) %/li
% end %
% end %
/ol
/div
And this is my RJS code:
page['#track' + @track_id].hide
I want to hide the li element of the track after deleting it from the
db.
In my application.js I have this:
jQuery.ajaxSetup({
'beforeSend': function(xhr){xhr.setRequestHeader('Accept',
'text/javascript')}
})
The problem is that after executing the delete action, the RJS code is
called, but it is not interpreted. The page prints the RJS as if it was
html code in the musicalUnitTile div, and I want to execute the RJS
code as Javascript.
What am I doing wrong?
Thanks!

[Rails] Re: Encrypting large amounts of text
Hi, Thanks for the responses. Sam, you mentioned that in your app, every user has his own pair of keys and the private key is stored encrypted with the users password. How many users does your system have? I was also considering trying to set something like this up, but I believe it will be far to much overhead for the number of users my system will have. As for limiting access to the private key (or password for that private key), I think that one good step here would be to store it seperately from both the application server and the database server. My concern here is that users will be requesting encrypted data fairly regularly, which means I will need to fetch the encrypted value from the DB, decrypt it, and provide the plaintext to the user (over an SSL connection). I am concerned about the type of overhead that retrieving the key/password from a remote server might be. Maybe this isn't the right approach for what I need to accomplish. In more detail, what I want is to allow users to be able to flag certain content to be encrypted within the DB. The system will have many users (possibly tens of thousands) that will be able to request to see this content when they are logged in (which will require the encrypted content to be retrieved, decrypted, and presented to the user). Still trying to iron this out. Any more thoughts on the issue?

[Rails] Code runs in development but not in test
I have some model code that runs fine in development environment but fails in the test environment. In test, the code always fails at the same point with: Mysql::Error: Duplicate entry '5-17' for key 'PRIMARY': INSERT INTO `accessibilities_namespaces` (`accessibility_id`, `namespace_id`) VALUES (17, 5) [0m accessibilities_namespaces is a join table for HABTM relationships. My logging suggests that ActiveRecord tries to insert the same record twice when run in test (but only in test!) which would explain the above error. I am sure that the code does not try to create the same record twice and in any case it runs fine in development mode. I have tried running the code using 'script/console test' and it fails here also. Though it does not fail when run in 'script/console [development]'. I suspect the problem does not lie with MySQL or ActiveRecord, but something to do with the differences between running in development vs test. Any thoughts appreciated.

Is it failing while running one of your tests (possibly an error in the test) or while preparing for the test (possibly a problem with your fixtures)? Colin 2009/5/8 Lee lee.longm...@googlemail.com I have some model code that runs fine in development environment but fails in the test environment. In test, the code always fails at the same point with: Mysql::Error: Duplicate entry '5-17' for key 'PRIMARY': INSERT INTO `accessibilities_namespaces` (`accessibility_id`, `namespace_id`) VALUES (17, 5) [0m accessibilities_namespaces is a join table for HABTM relationships. My logging suggests that ActiveRecord tries to insert the same record twice when run in test (but only in test!) which would explain the above error. I am sure that the code does not try to create the same record twice and in any case it runs fine in development mode. I have tried running the code using 'script/console test' and it fails here also. Though it does not fail when run in 'script/console [development]'. I suspect the problem does not lie with MySQL or ActiveRecord, but something to do with the differences between running in development vs test. Any thoughts appreciated.

[Rails] ActionController::Caching::Sweeper not autoloading
Hi
I've been following this issue on Lighthouse (https://
rails.lighthouseapp.com/projects/8994-ruby-on-rails/tickets/1977-
actioncontrollercachingsweeper-autoloading-is-broken). I've since
upgraded to 2-3-stable which contain's Josh's fix, but I'm still
seeing the same error:
`load_missing_constant': uninitialized constant
ActionController::Caching::Sweeper (NameError)
I've tried a variety of fixes as suggested in the Lighthouse comments,
all to no avail. The only way I can get my app to start is by
replacing:
@@@
class MySweeper ActionController::Caching::Sweeper
@@@
with
@@@
require 'rails/actionpack/lib/action_controller/caching/sweeper'
class MySweeper ActionController::Caching::Sweeping::Sweeper
@@@
This is clearly wrong.
Can anyone help?
My environment.rb file is as follows, if this helps?
Rails::Initializer.run do |config|
%w(sweepers observers accounting).each do |dir|
config.load_paths #{RAILS_ROOT}/app/#{dir}
end
config.cache_store = :file_store, #{RAILS_ROOT}/tmp/cache
config.active_record.observers = :my_sweeper
config.active_record.default_timezone = :utc
config.action_controller.session_store = :active_record_store
config.action_mailer.default_charset = utf-8
end

[Rails] Re: Code runs in development but not in test
Initially it was failing when running the code from within a Cucumber step definition. In this step definition, I am implementing a Given step (in part) by calling a method of a model. This method is throwing the error. In summary, the step definition is as follows: Given ... do user = User.create!(...) member=Member.add_member_for_user(user) ! error thrown by this method ... end Having experienced the error within Cucumber, I then entered the same code into 'script/console test' i.e. user=User.create!(...) member=Member.add_member_for_user etc... The code raised an error again. If however I run the code in development or by using the development console or as a standalone Ruby program which makes use of ActiveRecord and my models, it runs fine.

if we use another table and do the mapping through foreign key won;t

[Rails] Re: what database field type should i use ??
The question isn't really a performance issue, but rather one of
customization. If users are likely to need to add values to an
enumeration, (example: category for a blog post), then a lookup table
is a good idea. If the values are substantially unlikely to change
(see your examples - marriage status and state) then there's not a lot
to be gained by complicating the DB.

[Rails] Testing alternate css for printing
I am using an alternate style sheet for printing, loading it via %= stylesheet_link_tag 'print', :media = :print % which is working as expected. The problem is with testing, I would like to test that the layout is working correctly, in my controller functional tests, but I cannot see how to do this as, if I understand correctly, the style sheet selection change is made by the browser. I can check, for example, that items to be hidden are enclosed in divs of the appropriate class so that they should be hidden, but I cannot check that they actually will be hidden when printing. Is there any way to do this? Any suggestions will be appreciated. Colin --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

[Rails] Re: Confused about REST and custom actions
Robert,
This makes more sense now. Thanks for the explanation!
If anyone is interested, I decided to do it this way (from Agile Web
Development with Rails book) :
map.resources :widgets, :collection = { :popular = :get, :heaviest=
:get }
With this I can still add the custom method to my widgets controller.
This approach makes the most sense to me considering how my application
is organized.

Assuming it's happening server-side, the OP's author should realize that do this would render the open, and cross-platform nature of Ruby on Rails moot, effectively binding his application to run on Microsoft Windows only. It is, however, common to embed native C code in Ruby applications. This happens a lot with Gems. Do this requires compilation for the hardware running the Ruby application. This would, of course, require having the source code used to create the dll available. In my opinion it would be much better to create a web service that exposes a REST API. That API could then be used to integrate the functionality of the dll with the Rails application. This would decouple the two system and allow the Rails application to run on any hardware and access the web service that depends on the dll. -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

Perhaps I'm taking the wrong approach for dynamic divs so far my education: 1. id= , is fine for just one div and prototype activity in an RJS (I got this to work) 2. class= , another option, but I don't see how it can be used 3. div_for , a helper that uses ActiveRecord objects to come up with multiple divs Below: code that is my best guess for how to proceed, but it doesn't do everything it is supposed to do: script src='http://pastie.org/472556.js'/script script src='http://pastie.org/472563.js'/script -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

[Rails] Re: div_for and RJS
The class will not work for a rjs call.. html class elements are not unique by design so that is not a good idea anywho... Here is a good description for div_for http://apidock.com/rails/ActionView/Helpers/RecordTagHelper/div_for It's just a way to create a div that has something todo with the record that you have. So if you have a @user object with id of 1 you would get id=user_1 for the div. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

[Rails] Re: Gem path problems w/ Passenger+Apache2
Are you using passenger's ruby? Seems I remember reading that if you are you need to install gems via both the system-ruby and the passenger-ruby as they end up in different spots and passenger-ruby only looks for them in it's own directory heirarchy. -p On May 8, 2009, at 6:58 PM, Marc Byrd wrote: Platform - Ubuntu, 32-bit on EC2, jaunty jackalope On line that says require 'cloud_cache' it says file not found.

[Rails] Re: periodically autosave form
A caveat, It has to be done with the form already having been created. So doing an observe form with a form id will not work as the form id id being generated by rails as it is in edit mode.

[Rails] Re: periodically autosave form
I am not sure about your situation, but I would use observe_form set and :frequency to seconds at which changes to this field will be detected. This should work with the existing form.

[Rails] XMLRPC raw_post getting run through Hash#from_xml
Im trying to create an api, and Im having trouble getting ActionController to not run the raw post data through Hash#from_xml (request.parse_formatted_request_parameters) for the XMLRPC post data. I essentially want it to run through XMLRPC::XMLParser::REXMLStreamParser.new.parseMethodCall(request.raw_post). However, I can't figure out a clever, clean way to get request.request_parameters to not run since it can run as early as the dispatcher, which will essentially trigger Hash#from_xml on that call before it even gets into the scope of the controller. Anyone experience a problem like this before? Granted I can just let Hash#from_xml run and add a couple msec's to every call for no reason, but there should be a way around it. -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.
