Hello, First of all, I love RoR. I am studying it, and I am finally "getting there". However, I do have a bit of a problem with ActiveRecord''s saving behaviour. Imagine to have Orders (id, name) {has_one:invoice} and Invoices (id, order_id) {belongs_to :order} . If you type: invoice = Invoice.new(...whatever...) an_order.invoice = invoice if invoice fails to save, you

Hi, I''d like to create the following setup with RoR: www.mywebsite.com/subdir1/order/create www.mywebsite.com/subdir2/order/create I''d like both urls to call the same action in the same controller. How can I do this? I know this may be complicated, but I''m prepared to go a long way. Shimon -------------- next part -------------- An HTML attachment was scrubbed...

# Get a list of product ids from a form, then # sum the total price product_list = params[:product_ids] total = Product.find(product_list).sum(&:price) I understand the first list line and part of the second line, but what does the & symbol mean? TIA.

Hello everyone, I am following the Practical Rails: Social Networking sites book. In chapter 7 photo gallery I am getting a NoMethodError in Pages#show Showing layouts/_menu.rhtml where line #12 raised: undefined method `new_entry_path'' for #<ActionView::Base:0x52fa56c> Extracted source (around line #12): 9: <% if is_logged_in? %> 10:

Hi all, I''ve put new code into my app so that an administrator will have extra privileges (administer users, edit pages). The error is: ''Couldn''t find User without an ID'' So the app is looking for a logged in user when the homepage is accessed. Heres my code: site/index view: <% if is_logged_in? and logged_in_user.has_role?(''Moderator'')

Hi all, I am using rails v.2.3.2 and if I put following line to my ApplicationController: include LoginSystem and I moved my login_system.rb to lib folder: module LoginSystem protected def is_logged_in? @logged_in_user = User.find(session[:user]) if session[:user] end def logged_in_user return @logged_in_user if is_logged_in? end def logged_in_user=(user) if

Hi, I am trying to create a basic form in which I want one of the fields initialized before displaying it. My code (in a view) is as follows: <% if ( session[:user_id] != nil ) then logged_in_user = User.find(session[:user_id]) end %> <% form_for :suggestion do |form| %> <label for="suggestion_title">Topic:</label><br/> <%=

Hello! I have certain methods in my Application Controller, that I need to access. Namely ApplicationController#logged_in_user The problem is, that when I try to access it, I get: NoMethodError: protected method `logged_in_user'' called for #<AdminController> Any ideas how I can circumvent that? Or are functional tests really not suited for any kind of logins and session work?

I''m trying to create a simple authentication system but am failing miserably. I''m (sort of) following the "Logging In" chapter of the Agile book. Ideally, any access to http://example.com/publish (and any of its subdirectories) should redirect to http:/example.com/publish/login when there is no valid session user_id. Code so far:

Can you use sessions in layered dispatching? I used them in direct dispatching without any problems, but switching to layered throws an error (saying session doesn''t exist).

Hi,- I am looking for a clean and secure way for an ActiveRecord instance to delete itself. Say I have a User model in my app. Then the destructive action would be /users/user_id/destroy. If this action is not secured by a filter like: (*) before_filter :check_administrator_role, :only => :destroy then any user could potentially log in and start issuing: /users/1/destroy /users/2/destroy .

Hello! I was wondering, sometimes I raise an exception in my Rails apps, e.g.: raise SecurityError unless @post.user == logged_in_user Now: is there any way to catch that SecurityError exception somewhere and render a custom template? E.g., I want to render ''app/views/content/security_error.rhtml'' Does anyone know how to do this? Thanks a bunch, Rob

Hi all, I am using paperclip plugin to upload mp3''s. Before I save the mp3 I would like to convert it to a smaller size. I am using ffmpeg library and in my Track model I am calling: before_save :convert_mp3 def convert_mp3 system("ffmpeg -i #{mp3.to_file.path} -vn -ar 44100 -ac 2 -ab 64 -f mp3 #{mp3.to_file.path}") end But this fails. Am I missing something?

I am using mongrel_cluster with mod_proxy_balancer and would like to enable compression (assuming it improves throughtput) and limit file size upload. I configured mod_deflate and LimitRequestSize in Apache, but in my trials looks like the proxied calls bypass those directives (the conf goes below). Is there a way to get this? -- fxn # Adapt this .example locally, as usual. # # To be

Can I make my model methods aware of the context (preferably instance variables) where they are run, without having to pass them arguments? The app in question should be time zone aware, so something like user.events[0].starts_in should check against @logged_in_user.now rather than Time.now. I could send the user as an argument (user.events[0].starts_in(:timezoned => @logged_in_user)),

I read in the instructions of Tracks that "upgrading via the rake migrate command is quite a bit more tricky currently with SQLite and SQLite3". Is there any gotcha regarding migrations and SQLite3? -- fxn

I have an application with 15 migrations under version control. In a Mac and and in a Windows, a rake migrate from scratch runs them all just fine. But in a different Windows machine rake migrate stops after migration 3 for no apparent reason. --trace seems normal. No error is reported. Both Windows are XP SP2. They all have the same svn revision and Rails-related software, database is
