Hello, I have recently started learning RoR. I think it''s _fantastic_. I am absolutely blown away. OK, this is to prepare you to my idiotic question. Hopefully, I won''t be stoned. I am designing a simple application, where users can register, and: * Publish a photo album * Publish a simple blog with comments * Determine their list of friends and foes The application will

I''m having a strange thing when using the Enumerable extensions for Rails: Have a look at the following code: class Invoice < ActiveRecord::Base has_many :invoice_lines def total invoice_lines.sum(&:total) end end class InvoiceLine < ActiveRecord::Base belongs_to :invoice def total amount * price end end Now, when calling invoice.total, I get wrong

Hello, I have a bit of a problem - I have the feeling the solution is ridicolously trivial, and yet I can't find it! I have a remote repository of text files. Until today, I was the only one changing those files: I would simply change them locally, and update the remote repository with this command: cd local_dir rsync --delete -e ssh -Llavuz . merc@remote_server:remote_directory

Hello, Maybe this is super-trivial... I need to have a list of links on the left hand side of my application, for *every* single page. So, I''ve created a layout called "main" (main.rhtml) under view/layouts, and included >layout "main"< in pretty all of my controllers. main.rhtml has, amongst all the other HTML stuff: <%= render_component

Hello, I have a question for you. In my application, I want to make sure that the database doesn''t have any NULLs in fields. I can''t use validates_presence_of, because it will puke if there''s an empty string ("") So... is there an EASY way to check if a list of fields is null? Right now, I''m doing: def validate() [...]

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

Hello friends , I have a clear method here :: def create @invoiceitems = Invoiceitems.new(params[:invoiceitems]) @invoiceitems["invoice_id"] = params[:id] if @invoiceitems.save flash[:notice] = ''Invoiceitems was successfully created.'' redirect_to :action => ''new'',:id => params[:id] else render :action =>

Hi I have the following code, which makes use of an sql statment to get the results required. However this just doesnt seem right for rails, as ive managed to develop the whole project without using any other pure sql. Is there a cleaner way of doing this, but gaining the same results. thanks scott #sql to find all invoices pSql = "SELECT DISTINCT invoices.id,

hello friends , I was trying to select all the invoice items from the table invoiceitems with a condition.But I am getting a NULL array .Please help me in fixing this :: @oldinvoiceitems = Invoiceitems.find(:all, :conditions => [''invoice_id = :invoiceid'', { :invoiceid => ''params[:id]'' } ] ) Thanx and regards, Naroor Rathish,

Hello, It''s pretty hard giving a practical example on this one. I have a partial which contains some generated Javascript. Something like: order_screen.rhtml ------------------------------------------- <h1>Order</h1> <div id="order_part"> <%=render :partial=>''order_new'' %> </div> <h1>Ordered products</h1>

Hi, I wanna make a invoice system. I''ve set up a invoice model and a invoice_item model (invoice has_many invoice_item and invoice_item belongs_to invoice). Also invoice belongs_to a customer, and a customer has_many invoice. My problem is i don''t know how to create the form for making a new invoice. I''ve made a similar system in php, and here is how the html form was:

I have a weird problem going on. All of sudden, records for a certain model will not save with #save Please take a look at this: >> p = Payment.new(:payment_reason_id => 1, :payment_method_id => 1, :date => Date.today, :amount => ''5.00'', :payable => Student.find(608)) => #<Payment id: nil, school_id: nil, payment_reason_id: 1, payment_method_id: 1,

Hello Friends, def new @invoiceitems = Invoiceitems.new @oldinvoiceitems = Invoiceitems.find(:all, :conditions =>[''invoice_id = :invoiceid'', { :invoiceid => params[:id] } ] end Error is being shown in the line number with ''end''.

Hi, I''m having great fun developing with Rails but I''ve come to a problem that I can''t quite figure out. I have an Order object that "has_many" order_lines. This works perfectly and I can see all the lines. The OrderLine object has an order_id field as well as product_id and amount. Now ideally I would want to do : order.orderline[0].product.name for

Hi, it probably is a noob question but I''m confused by this error message: active_support/dependencies.rb:478:in `const_missing'': uninitialized constant Invoice::ApplicationController Situation: I have an InvoicesController with a create method that in turn calls upon a MiddleMan.worker(:billing_worker), which in turn finds an Invoice and calls upon @invoice.print_invoice

Hi.. Guys new plugin again Foreign Key Associations is a plugin that automatically creates associations based on foreign-keys. The associations are created at runtime-ie. as your ActiveRecord models are loaded-so they will always be up-to-date. For example, given a foreign-key from a customer_id column in an orders table to an id column in a customers table, the plugin creates:
