Hi, I''m trying to work with a RESTful server but I have some problem to setup my project. I have a model class like this : class User < ActiveResource::Base self.site => "http://diufvm31.unifr.ch:8090/CyberCoachServer/resources/users/"end this controller : class UsersController < ApplicationController def new end def index @users = User.find(:all)> respond_to do |format|format.html # index.html.erb format.json { render :json => @users } format.xml { render :xml => @users} end end end and simply this view : <% @users.each do |user| %> <p><%= user.username %></p> <% end %> But I can''t retrieve the data, @users is empty. Anyone has an idea how to fix this issue? Thanks -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I think you need to enable logging so that you can see what activeresource is doing. I have not used activeresource but a quick google found [1] which looks useful and has a section Logging Requests. Hopefully you will then see what is going on.

Yes, good idea, now I can understand where is the problem : GET http://diufvm31.unifr.ch:8090/CyberCoachServer/resources/users/users.xml --> 404 Not Found 32 (129ms) The server is not configured to respond for .xml (or .json). The content type should be defined in the header... Is it possible to setup this in ruby...?

Yes, it''s for a project in my university. I know that the we need to
specify the format in the header and the server can handle json and xml
format.
Here is the documentation :
Read only resources:
- SportsResource / - Get list of all sports [GET, public]
- UsersResource /users/ - Get list of all users [GET, public]
- PartnershipsResource /partnerships/ - Get list of all partnerships [GET,
public]
- SportResource /sports/{sportname} - Get sport entity and its list of
subscriptions [GET, public]
"Public" write resources:
- UserResource /users/{username} - Get user entity [GET, public*] - Create
new user [PUT, public]
- Update user profile [PUT, private] - Delete user [DELETE, private]
Private write resources:
- PartnershipResource /partnerships/{username1};{username2}/ - Get
partnership entity [GET, public*]
- Propose (or confirm** proposed) partnership [PUT, private]
- Delete (or decline** proposed) partnership [DELETE, private]
- SubscriptionResource /users/{username}/{sportname} - Get subscription
entity [GET, public*] /partnerships/{username1};{username2}/{sportname}/ -
Subscribe (as user or partnership) to a sport [PUT, private]
- Update subscription [PUT, private]
- Submit new entry [POST, private]
- Delete subscription [DELETE, private]
- EntryResource /[uri of subscription]/{entityid} - Get entry entity [GET,
public*] - Update entry data [PUT, private]
- Delete entry [DELETE, private]
* = Read accessability depends on the privacy settings for the respective
entities ** = A partnership is created/deleted in the following way:
-
PUT by user1 proposes a new partnership. PUT by user2 confirmes the
proposal and the partnership becomes "operational"
-
DELETE on an operational partnership results in a proposed partnership.
DELETE on a proposed partnership deletes it.

Yes, sorry I made a mistake it''s only users.xml but the problem is the same... Is it possible to retrieve the data without the extension .xml but just specify the type in the header?

So, I tried to overwrite the methode collection_path :
def collection_path(prefix_options = {}, query_options = nil)
check_prefix_options(prefix_options)
prefix_options, query_options = split_options(prefix_options) if
query_options.nil?
"#{prefix(prefix_options)}#{collection_name}.#{format.extension}#{query_string(query_options)}"
end
by
def collection_path(prefix_options = {}, query_options = nil)
check_prefix_options(prefix_options)
prefix_options, query_options = split_options(prefix_options) if
query_options.nil?
"#{prefix(prefix_options)}#{collection_name}#{query_string(query_options)}"
end
And now it''s OK :)
*GET http://diufvm31.unifr.ch:8090/CyberCoachServer/resources/users
--> 200 OK 1260 (1735.7ms)
*
*
*
...But :(
I have an other error now :
> NoMethodError (undefined method `collect!'' for
#<Hash:0x1030aeed0>):
> app/controllers/users_controller.rb:6:in `index''
Anyone has an idea
Thanks a lot for your support!

It''s finally seems to work :)
My ActiveResource model looks like this :
class User < ActiveResource::Base
class << self
def element_path(id, prefix_options = {}, query_options = nil)
check_prefix_options(prefix_options)
prefix_options, query_options = split_options(prefix_options) if

"#{prefix(prefix_options)}#{collection_name}/#{URI.parser.escape
id.to_s}#{query_string(query_options)}"
end

check_prefix_options(prefix_options)
prefix_options, query_options = split_options(prefix_options) if
query_options.nil?
"#{prefix(prefix_options)}#{collection_name}#{query_string(query_options)}"
end
def instantiate_collection(collection, prefix_options = {})
collection = collection[element_name.pluralize] if
collection.instance_of?(Hash)
collection.collect! { |record| instantiate_record(record,
prefix_options) }
end
end
self.site =
"http://diufvm31.unifr.ch:8090/CyberCoachServer/resources/"
end
I founded how to solve the last error here
