Hi, I have been building a invoice generator(in ruby on rails) for the past some days and been stuck on the final page .This page will have fields for entering the invoice details and also I have added a AJAX effect so that fields for invoice items get created dynamically . its all design well but the issue comes when I am trying to save the page .That is adding ivoice details to invoices

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:

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:

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

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

Hey all, Could use a few eyes on a couple of very simple patches at https://rails.lighthouseapp.com/projects/8994/tickets/6262 if any has some time. The issue (from the ticket description): If you define a polymorphic belongs_to association and it has conditions on it, those conditions cause a NameError when you try to access the target object, of the style saying "hey, there''s no

Hey all, I''m not positive if this is a Engines bug, but it seems very peculiar and a few hours of Googling haven''t given me any good leads yet, so I thought I''d see if it makes sense to any of you: I am writing a new version of the savage_beast plugin (implements Beast forums as a plugin) that''s Rails 2.0 compatible, and I am having trouble with the many

Dear List, I''m using Edge Rails. I have a Model with Items for purchase. Each Item is of a certain brand. Class Brand < ActiveRecord::Base end Class Item < ActiveRecord::Base belongs_to :brand end The problem domain is that I''d like to create a separate Inventory list of Items. This includes the date of entry into inventory and date of exit from inventory (ie

Perhaps this is intentional, but it seems unlikely: class Person < ActiveRecord::Base belongs_to :school end p = Person.find(:first) p.school # nil p.school_id = School.find_by_name(''High School'').id p.school.name # High School p.school_id = School.find_by_name(''Primary School'').id p.school.name # High School <= Shouldn''t this be Primary

I''ve been reading up in ActiveRecord::Associations and playing around with my app via the console and found some interesting methods via the code completion of IRB, but I have no idea how to use them and can only find one hint in the API http://api.rubyonrails.com/classes/ActiveRecord/Associations/ ClassMethods.html It mentions here in the has many associations that if you use the

I am trying to build a shared-appointment system, where users can subscribe to appointments and be updated whenever changes are made to them. I have three objects in this system, appointments, users, and subscribers. Subscribers are a polymorphic object like so: class Subscriber < ActiveRecord::Base belongs_to :user belongs_to :subscribable, :polymorphic => true end The tricky part is

is it possible to implement a recursive foreign key association like that? i''m writing a vocab app, where i want the vocab table to have an id and two foreign keys, word1 and word2. the word table will have an id, a word-string, and a language i''m trying to do this as follows: class Vocab < ActiveRecord::Base belongs_to :word belongs_to :word class Word <

Dear all I am using magic multi connections, there is some problem when using association. How can I dynamic determine the module name (i.e. A::Request, B::Request) in activerecord association. Below is my code: module A establish_connection :A end module B establish_connection :B end # and many module.... class Request < ActiveRecord::Base set_table_name "request"

I''ve encountered what seems like an odd omission in the behaviour of belongs_to associations: if you assign to the foreign key attribute, it doesn''t update the associated object (or mark a previously loaded one as stale) until you explicitly save or reload it. Let''s say we have a Company model, which belongs_to :city : >> torchbox =

Hi, I am new to ruby on rails. I am building an association join model and encountered the following error. Does anyone know what am I missing? > NameError in StartController#home > >d:/ruby/lib/ruby/gems/1.8/gems/activesupport-1.3.1/lib/active_support/dependencies.rb:100:in `const_missing'': uninitialized constant Membership I have the following tables relationships Users

Hi, Haven''t been able to find this raised before but I''m sure it must have been. When assigning an object to a belongs_to association I would like it to call the *association*_id= method instead of directly updating the attributes array. This is because I want to modify the behaviour when assigning a particular object without writing separate methods for whether it''s

Hello all, I''m having a strange issue with a model that belongs_to two other models. The one association is polymorphic and the other is normal. ================================ class Role < ActiveRecord::Base belongs_to :user belongs_to :permission, :polymorphic => true end class User < ActiveRecord::Base has_many :roles has_many :programs, :through => :roles end

I''ve gotten eager associations to work before, but for some reason this isn''t working out for me this time. I''ve been scratching my head but can''t quite figure out the nuances of what works and what doesn''t work. I''ve got 3 models: profile, widget_configuration and widgets profile.rb -- has_many :widget_configurations

class Trunk < ActiveRecord::Base has_many :call_type_trunks has_many :call_types, :through => :call_type_trunks end class CallType < ActiveRecord::Base has_many :call_type_trunks has_many :trunks, :through => :call_type_trunks end class CallTypeTrunk < ActiveRecord::Base belongs_to :call_type belongs_to :trunk end The associaton class has a column named price.

I?m following along a few tutorials on the web and trying to implement my own example, but I must be missing something because I can?t get has_many or belongs_to to work like I expected. now I have watched all the videos and made a cookbook several times with different interfaces. what I''m looking for is *not* a code snippet to solve something (because I already have that),
