But I have FIXED it. Turns out this is a bug in mongrel. Normally I would not have believed this as this was working just fine before and then suddenly stopped. Admittedly I can't remember what little I did to mess it up but I'm thinking a gem got messed up or a bad one got installed. Here's the website that helped me out.. http://mongrel.rubyforge.org/ticket/37 There's a bunch of weird links are you go through the comments about n1ke (had to put in a 1 there since ruby-forum thought I was spamming) shoes and stuff.. Ignore that. In fact don't bother reading past the attachments section. Click on it or go to this link which is the patch file. I didn't bother grabbing the patch I just fixed it manually.. Link is here.. http://mongrel.rubyforge.org/attachment/ticket/37/37-fix-infinite-loop-error-in-gem-require.patch You'll noticed that they replaced the "retry" with "Kernel.require library". I guess Mongrel can go into an infinite loop if it see a gem installed but the file inside it doesn't exist (at least that's what I read). Anyway I edited the bad file and it works great now. On my mac the file existed here and use sudo vi to edit it (here's the entire commandline command)... sudo vi /opt/local/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/../lib/mongrel/gems.rb You'll notice it goes back a directory between bin and lib. This was a copy paste I grabbed. I guess you could just cut out the bin/../ and just shove in the rest starting at lib. :) Anyway, I'm fairly new to ruby and rails and am just trying to learn. This was a baffling mystery to me and I thought it was all in my code. I re-installed ruby, rails, mongrel, postgres, etc.. many times without success.. I hope this helps someone else who runs into this in the future. It was frustrating. It's not often the error is not in your own code. :) (Although granted I must've screwed up a gem somehow for this bug to surface only on this one computer. :) ) Thanks for the prior responses as well.

[Rails] Annoying problem with file_field and paperclip
Hi all, I have a really really annoying problem that's driving me nuts with file_field and paperclip and having to upload images everytime a form is edited even though the user is quite happy with the currently uploaded image or loose the previously uploaded image. This seems to be caused by the rails file_field helper not storing the data that has been read in from the db in the same way that other field helpers do and therfore unless an image is uploaded everytime the form is updated the data for the current image does not get sent back to the controller in the params hash. This in turn causes the model to believe that the data has been deleted. This is obviously a problem with the rails helper as it should work the same way as all the other field helpers do and retain the data somehow but right now I need a work around. Javascript is not an option as the site is a W3C AAA compliant site and creating a seperate form is just plain wrong as the user has enough to do without adding more button clicks. Any ideas would be greatly appreciated. -- 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] From 3 fields :date input from forms to 1 field
Hi Rails community, here is my newbie problem (I'm migrating from PHP to ruby due to framework and ruby syntax, but I'm having some problems with "freedom" that a single php page offers): I'm using the scaffolding technique (yea, I love it) to create a webpage, but if I specify that a field type is :date, Rails auto generate a form where the field of type :date is created through 3 fields: day, month and year. I would like to use only one field (always) (will be something that I'll use for all :date field-type), a text field, where the date will be written in dd/mm/YY format, how can I do this without writing something in javascript that "set some hidden fields" (month and year) when you write in the text field? Are there a "general" way (as I've said, I'll use this always instead of normal way of setting dates)?

Hello, I have a message model which belongs to a user. Users can be deleted, but messages cannot.

When a user is deleted, assign the dummy user id to all of its messages. 2) Have a condition to check if the user exists, if not, don't show the user info. 3) Don't really delete the user, just flag it or change its state to inactive. These 3 occured to me. Any other options I should have in consideration? Which one should I follow?

[Rails] Re: postgres adapater problem with create_table :id => false
I tried the composite_primary_keys (2.3.2) plugin, with the same
overall result: I cannot insert a row (via Postgres) into a table
without a PK. My model now has this line:
set_primary_keys :doc_id, :user_id, :view_date, :view_time #
legacy tbl, include all cols
My insert error is thus:
Mcolumn "doc_id,user_id,view_date,view_time" does not exist
P170
Fparse_expr.c
L421
RtransformColumnRef: INSERT INTO "document_ref_access" ("doc_id",
"user_id",
"view_date", "view_time") VALUES (1, E'W:5:a_name', '2009-10-19',
'2009-10-1
9 14:52:11.605227') RETURNING "doc_id,user_id,view_date,view_time")
The RETURNING clause seems to be causing the problem. If I set the PK
to, say, :doc_id (mind you this col is NOT a PK for this table) the
insert works but the doc_id col is set to NULL. Any other suggestions?
Thanks,
Jeff

[Rails] Combobox population by means of JQuery and Ajax.
This is the view municipalities.js.erb I have:
<% list_opt = options_from_collection_for_select(@municipalities, :id,
:name) %>
<% puts list_opt %> #ok! list_opt contains the options
$('#municipality_id').html('<%= list_opt %>');
and this is the combobox in the view:
...
Comune
...
if instead of '<%= list_opt %>' I manually assign the string
'Alagna
Albano
AliceCastello
Arborio
...'
into list_opt then the combo municipality_id correctly works,
if I use options_from_collection_for_select doesn't works (empy
combobox)
but that string is the same of options_from_collection_for_select
then why doesn't work ? :(

[Rails] ActiveRecord abstract_class and model inheritance
Hi everybody,
I'm having problems on a testcase that I'm working on. I hope that I can
explain the problem properly and that some of you can help me out
becouse I'm realy stuck on this one.
Ok, I have a Page model that needs to be multi lingual. Therefore I have
used a small but nice plugin: http://github.com/janne/model_translations
. Basically, I had to create a new model PageTranslation that conatains
the i18n attributes. Let me draw a small example:
Page
id
parent_id
PageTranslation
---
title
Now I want to use these object for the base of other objects. So I used
polymophisme on the page and page translation. Becouse of the
inheritance, I have created an abstract model for Page and
PageTranslation where other objects can inherit from. As an example
object, I'll use a new object StaticPage. This is what I have so far:
class Page < ActiveRecord::Base
has_many :page_translations
belongs_to :content, :polymorphic => true
belongs_to :parent, :class_name => 'Page'
has_many :children, :class_name => 'Page', :foreign_key => 'parent_id'
end
class PageTranslation < ActiveRecord::Base
belongs_to :page
belongs_to :content_translation, :polymorphic => true
end
class PageModel < ActiveRecord::Base
self.abstract_class = true
has_one :page, :as => :content, :dependent => :destroy
validates_presence_of :page
validates_associated :page
after_save :save_page
translates :locale, :slug, :keywords, :description, :title, :content
Page.column_names.each do |attribute|
if attribute != "id"
define_method "#{attribute}=".to_sym do |value|
init_page
self.page["#{attribute}"] = value
end
define_method "#{attribute}".to_sym do
self.page[attribute] if self.page
end
end
end
def children
self.page.children if self.page
end
private
def init_page
self.page = Page.new unless self.page
end
def save_page
self.page.save(false)
end
end
class PageTranslationModel < ActiveRecord::Base
self.abstract_class = true
has_one :page_translation, :as => :content_translation, :dependent =>
:destroy
validates_presence_of :page_translation
validates_associated :page_translation
after_save :save_page_translation
PageTranslation.column_names.each do |attribute|
if attribute != "id"
define_method "#{attribute}=".to_sym do |value|
init_page_translation
self.page_translation["#{attribute}"] = value
end
define_method "#{attribute}".to_sym do
self.page_translation[attribute] if self.page_translation
end
end
end
private
def init_page_translation
self.page_translation = PageTranslation.new unless
self.page_translation
end
def save_page_translation
self.page_translation.save(false)
end
end
class StaticPage < PageModel
end
class StaticPageTranslation < PageTranslationModel
end
For testing, I've created a simple form like this:
<% form_for(@static_page, :url => static_pages_path , :html => { :id =>
"static-page-form" }) do |f| %>
<% end %>
This test works like a charm. The static page gets saved and the content
get synchronized with the page table. So that part works.
The part I can't get to work, is the part with the translations.
I have used the model translation plugin on a simpler test case and got
it to work by adding the following to a model:
has_many :test_translations
after_update :save_translations
def new_translation_attributes=(translation_attributes)
translation_attributes.each do |attributes|
test_translations.build(attributes)
end
end
def existing_translation_attributes=(translation_attributes)
test_translations.reject(&:new_record?).each do |translation|
attributes = translation_attributes[translation.id.to_s]
if attributes
test_translation.attributes = attributes
else
test_translations.destroy(translation)
end
end
end
def save_translations
test_translations.each do |translation|
translation.save(false)
end
end
And have my form fields like this:
But I don't seem to be able to implement this pattern in my abstract
PageModel.
It would be great if someone could help me out with this one, becouse I
don't think I would be able to solve this without any help.
Thank you in advance

Your ServicesController is in a non-standard location. Thus, what's the
reasoning for having ServicesController within the production directory?
In any case, you should be able to do the following:
config.load_paths += %W( #{RAILS_ROOT}/app/controllers/production )
The above adds the production directory to your load path.

[Rails] problems with calling javascript containing dynamic content in partial page
Hi all,
I am trying to call some javascript function defined in partial page
"_results.html.erb". But it seemed that the js functions in the page
are unrecognizable, and I have no idea why.
In my app, I have an "index" action/view containing an form_remote_tag
sending the ajax request to a "process" action. After some calculation
in the "process" action, it passes a local variable to a result page
and renders it partially. Briefly, the index.html.erb looks like:
# index.html.erb
<% form_remote_tag :url => 'process',
:id => 'inputs',
:update => {:success => 'result_div', :failure =>
'document.write(request.responseText)'} do -%>
# some input tags here
<%= submit_tag "calculate" %>
<% end -%>
In controller#index, there is nothing. In controller#process, there is
the calculation code which will cost several seconds, after that it is
the render method:
def process
# calculation code which will generate a result - @ruby_result -
which is an ruby object
render :partial => 'results', :locals => {:ruby_result =>
@ruby_result}
end
And in _results.html.erb:
show result
function showResult()
{
// code to show the result somewhere else on the index page
// BUT I MUST use the <%=ruby_result%> variable here
}
The update of the result_div is totally ok, but when I click on the
"show result", nothing happened. I tried putting the showResult()
function in the index.html.erb. Then it can be found by the
_results.html.erb. However the problem is that the ruby_result can
only be got after the process. As a result, it's not accessible in the
index view when it is initially loaded. How should I solve this
problem?
I am not sure if I have expressed my question clearly. Any reply or
comment is welcome.
Thanks!

If it returns a 404 error or maybe even a 500 error I'd like it to have the method return true, but also a message saying there's something the user needs to look into at their end.

I believe that Ryan tends to prefer using gem dependencies instead of plugins when possible. This is also my own preference. I would guess that there is no further explanation provided because it seems to depend upon personal preference. I tend to prefer managing shared libraries outside of my application. I feel it eases management of shared libraries and makes upgrading my applications to use the newer version easier.

[Rails] Re: Authlogic -- gem or plugin?
The argument for the gem is that any improvements in security/bug fixes will be automatically included in your application if you continue to update your gems. The argument for the plugin is any changes in the gem won't break your code that was already working if you don't update your plugin. I would use the updating gem in development.

Good luck! Sorry you spent so much time on this. Maybe I -will- try to develop some kind of gem for this, but don't hold me to it..

[Rails] find, using a link instead of a form
Hello; Here's the latest puzzle stumping me. Seems it should be simple but I'm feeling like a moron. I would like to have a link that, when clicked, returns the results of a pre-set find. Here's the deal. I'm working on a contact management and scheduling app for the photo studio I work for. I want our staff to be able to create assignments (think of them as events). Most of the time when an assignment is booked, a date and time are established. But sometimes the date isn't certain. Other times we find that an assignment needs to be rescheduled but the client doesn't yet know when. In either of those cases, the database column "starts_at" (of type datetime) will be empty. I would like the user interface to have a link (something like "Pending Assignments") which, when clicked, would find and display all assignments for which starts_at is empty. Or starts_at.year, or starts_at.day or whatever. I want this to be a link rather than a form input because the find criteria is always going to be the same. I installed the Searchlogic gem but can't come up with how to get it to do what I want. I have an index action in the assignments_controller that basically does an @assignments = Assignment.find(:all). Can I leverage that so that it returns a select set if there is some criteria and all Assignments if not? I guess the "some criteria" part is what eludes me. Thanks for any suggestions and pointers.

Nice idea, but this is a legacy enterprise database used by other software, not so easy to abandon it. My new plan (not really related to this thread, but perhaps useful for someone thinking about these things) is to write a web service in Java (there is already plenty of java code to talk to this db) that provides just the information needed by my ruby app (not actually the entirety of the database, not even close, just a few pieces of info, almost entirely read-only, for a few specific use cases) -- and just have the ruby app consume the web service instead. -- 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: Using Initializers
I have another example that I have used for a while...
/config/settings.yml
all: &all_environment_settings
constant_for_all: somethinf
development: &non_production_settings
<<: *all_environment_settings
something_different_for_dev: dev stuff
Then you can load this file in a initializer:
/initializers/settings.rb
SETTINGS = YAML.load_file("#{RAILS_ROOT}/config/settings.yml")
[RAILS_ENV].symbolize_keys
Now you can call this through SETTINGS[:constant_for_all]
Both methods will work but if you have requirements for the constants
to change between environments then this would be better...

While there may be some small overhead introduced by the load balancer it certainly does not offset the scalability advantages they provide. If you add just one additional instance of the application though a load balancer, it would have to slow the requests down by one half to loose overall scaleability. I'm sure that they do not introduce that level of overhead. The overhead is more likely negligible. -- 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] map.resources + has_many + STI + :only
Hello
I have product model that has a given workflow (given by
state_machine). Then I have 2-3 versions of product that have a
slightly different workflow. Since state_machine has a elegant way of
handling class inheritance (compared to aasm), I have 2-3 models that
inherit from Product. (ProductOne, ProductTwo, etc). The Product model
has_many transisions. this is a hm relationship that basically handles
all transisions/events RESTfully. I also get transision logging by
having this transision model.
My question is how this is implemented as DRY as possible in
routes.rb. this is how my routes.rb looks like today:
map.resources :products do |product|
product.resources :transisions, :only => [ :index, :new, :create ]
end
map.resources :product_one, :as => 'products', :controller =>
'products' do |product|
product.resources :transisions, :only => [ :index, :new, :create ]
end
map.resources :product_two, :as => 'products', :controller =>
'products' do |product|
product.resources :transisions, :only => [ :index, :new, :create ]
end
map.resources :product_three, :as => 'products', :controller =>
'products' do |product|
product.resources :transisions, :only => [ :index, :new, :create ]
end
Is there a more elegant way to handle this. goal is to have only
"products" routes. I do not want separate routes for each variant of
product.
I tried this but it did not work :-):
map.resources :products, :has_many => [ :transisions => { :only =>
[:index, :new, :create] } ]

[Rails] Re: Rails Concurrent Requests
On the other hand, Clustering or pooling are solutions for Reliability not for performance. Clustering does not give better performance, in fact, most of the times gives you less performance one of the reasons is the load balancer. It's true that every application has a limit of request to handle, all the servers have that limit, and there is where you need to do a pool or a cluster to "solve" the problem, but if my limit is "one request", i should think i have another problem..

[Rails] submit_tag or f.submit
Hello all, I am pretty much new here, trying to move to RoR from .net world. I will appreciate if anyone clarifies this for me. Most of books use "submit_tag" in new or edit views, but I see Rails API web documents use "f.submit" instead. I also see Agile Web Development using RoR 3rd Edition use the same "f.submit" instead of "submit_tag." Which way is mostly recommended? I am using the latest version of rails, and I am still get confused how Rails know if the post is "Create" or "Update" with this one single "submit_tag." I will appreciate it for your help in advance. - risknet - -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

What you have inside the column block technically doesn't have to do anything with how you filter/order, etc, so you can have the following: g.column :attribute_name => 'firstname' do |person| person.firstname + ' ' + person.lastname + ' ' + person.telephone end > Is it possible to specify one of the elements I > put in a column as the one to use for sorting? So that I could put > name, address, and phone in the column, but sort/filter on name only? Yes. In the column clause you define the column you want to filter by, and then you redefine which column you want to use for ordering using :custom_order. see the example at http://grid.leikind.org/custom_ordering2, controller code, or here http://grid.leikind.org/custom_filters2 . Basically, the key of the hash is the database column defined in your column clause, and the value is any other column you want to use for ordering, or any valid sql expression (see here http://grid.leikind.org/custom_ordering, controller code) Best regards, Yuri --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

How were you able to get it to return the > same token for 2 different sessions ? According to the code for 2.2.2 (and also the current version), the token is not inherently "user-specific"; it may remain the same even when other session fields change. Thus, the app _must_ use reset_session when a different user logs in to force a different token to be computed. (In particular, just clearing out the relevant fields, e.g., session[:user_id], is not enough, since session[:_csrf_token] or session[:csrf_id] remains set.) Otherwise, we may get the following scenario, for example. 1. Attacker logs into a public computer, gets CSRF token from a page returned by the server, includes a form with that token on a popular website he controls, and leaves without logging out. 2. Honest user logs into the same computer (and say reset_session is not used, so the token field in the session remains set and doesn't change). He opens the popular site on the side, and accidentally causes the malicious form to be sent. I discussed this issue with Michael Koziarski; he claims, perhaps rightly so, that this is ultimately a session fixation attack, and the doc already advises use of reset_session in that case. True, but I believe that the doc is inadequate in this case; clearly this attack uses CSRF, and the fact that protection in this case requires protect_from_forgery as well as reset_session is not clarified enough.

You are actually illustrating the point to state machines. Yes, in this simple example you can implement them using a series of conditionals, but not every state machine is this simple. You could end up with a lot of conditionals and the code could end up being difficult to follow. Good design is not always about producing the fewest number of lines. Sometimes a more verbose and descriptive code can improve maintainability. -- Posted via http://www.ruby-forum.com/. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

The documentation and examples are as impressive as the demonstrated functionality. Very well done! Your timing is very convenient for me too and I think I'll be giving it a try this week. One thing I haven't been able to find in the documentation so far... If I understand correctly, I can put more than just a single attribute value in a column. For example, assuming I have separate columns in the database for customer name, address, and phone number, I can put all of them in one display column. Yes? Is it possible to do that AND to still have the ability to sort the grid based on that column? Is it possible to specify one of the elements I put in a column as the one to use for sorting? So that I could put name, address, and phone in the column, but sort/filter on name only? Thanks for your reply, and for your contribution!

The soution they outline is very specific to twitter. Alto bear this in mind, their system breaks down a little when you decide to follow another user, you then have to find all (all of the historical, just the last day? just the last 100? what?) their posts, and insert them into your private post stream, which could get quite intensive. Granted it doesn't happen as often as searching, or posting, but it could have a big impact. To answer your question though. You would probably have a users table, and that would have a one to many relation to entries in a _stream table. The logic that creates the user in the database would first create the _stream table, and then create the actual user. You would need a fair bit of reflection on the ruby side to get that to work, as their wouldn't be anything in the DB to directly connect the two tables. Which sounds a bit fishy to me. Although I guess you could have _stream as the table name, which is a little less ambiguous.

[Rails] Re: Can (should) each :user have his own table?
Thank you for the reply. I would, but that's exactly what that article was saying to steer clear of, and it makes sense. If you have to keep querying the same table for everyone's new posts and post them back to your "feed" of the people that you follow, wouldn't that cause serious bottlenecks and lead to outages? (which is exactly what I think is/was happening with twitter) And right now I'm just at the hypothetical stage as I'm still learning rails, so I don't have any constraints or requirements of what I'm trying to do. I was just saying if my app was heavily intensive on user read/writes so that other users could follow other users, wouldn't it be best to give each their own table?

[Rails] Odd behaviour of update_attributes in STI table
I just noticed this odd behaviour (in rails 2.2.2). It looks like changing the type with update_attributes *doesn't* work (but returns true!), but changing the field and then saving it *does* work. Here i have an STI situation where TeachingObject and LearningObject extend Resource. The bit where update_attributes returns true, yet seems to fail, is rather disconcerting. Can anyone explain what's going on here? thanks -max >> resource = Resource.first => # > >> resource.update_attributes(:type => "LearningObject") => true >> resource = Resource.first => # > >> resource.type = "LearningObject" => "LearningObject" >> resource.save => true >> resource = Resource.first => # > -- 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: Linked associations question please help
Thanks so much for the quick response. Yes that makes sense, and I wasn't aware it was possible. However having added to my User model: has_many :items, :through=>:stories I am getting the following error when trying to call @user.items ActiveRecord::HasManyThroughSourceAssociationMacroError: Invalid source reflection macro :has_many :through for has_many :items, :through => :stories. Use :source to specify the source reflection. I have to admit Reflections are something beyond my knowledge, and I noted suggestions that nested HABTM associations weren't supported in earlier versions of Rails. Any thoughts?

[Rails] Can (should) each :user have his own table?
I was reading this article a while back http://www.sitepoint.com/blogs/2008/06/06/did-rails-sink-twitter/ and it got me thinking. If I wanted to set up my app so that each user has his/her own table, how would I go about doing that? "create_table :users" just creates a table in the database for a list of all the users (which I guess I'd want in addition to their individual tables), but is there a way to make it create an new table for each user? Would this even be the best way if my app allowed "followers?" Admittedly there'd be a ton of tables in my database, but wouldn't it make it easier for indexing all of your followers messages?

[Rails] Linked associations question please help
I have a Users model. Users 'have many' Stories, and Stories have many Items. This structure allows the sharing of Items between Stories and Stories between Users. But given there is no direct 'ownership' link between Users and Items, what is the best way of building a list of Items which belong to a Story to which a given User has access. something like: current_user.stories.items obviously doesn't work. I've written some nested blocks ie: users.each do |user| user.stories.each.do |story| story.items.each.do |item| end end end which works but is ugly and slow. I could keep an index table of items linked to users but this is redundant for most of my application. I'm sure there is a more obvious, simple way of doing this but I haven't come across it.
