similar to: Validation dependent on unsaved parent

hi, can''t find any good tutorial or advice to deal with the creation of a new record and it''s associated objects within the same page. do i have to use ajax just to add custom form fields that will be handled by the controller for associated objects creation.? do i have to use ajax to add associated objects to the unsaved but allready in session parent object? what''s

I''m willing to write a patch for this issue: https://github.com/rails/rails/issues/8893 But want to confirm that the new behavior makes sense before I make the effort. Essentially if you have an unsaved parent and child, and the parent''s association to the child has an inverse_of declared on it. When the parent gets saved, it updates the foreign key on the child, and this

I have two tables: class PgmUpdate < ActiveRecord::Base has_many :pgm_visits, :foreign_key => ''pgm_update_fk'' ... and class PgmVisit < ActiveRecord::Base belongs_to :pgm_update, :foreign_key => ''pgm_update_fk'', :dependent => true ... According to the has_many docs (http://api.rubyonrails.org/classes/

Given the two tables Parent, Child where Parent has_many children: If I don''t save parent first then it seems that child.parent will not be assigned automatically if I call parent.children << child . Must the parent record be saved before I call parent.children << child ? If I must save Parent first then can someone explain to me how I can call parent.valid? before it

Hello, I am implementing a classic invoice application. On the create new invoice page I want to allow users to add new line items using AJAX: ----------------------------------------------------------------------------- Invoice Date [ ] Client [ ] Line Items 1. [ ] $[ ] <add new line item> <save> <cancel>

Hi everyone, I am relatively new to rspec and I am running into a wall in testing my views. I have a RESTful resource Contracts with a nested resource of Line_items. I am trying to figure out how to test the "edit" form of the Line_items. What complicates this is the nested routing and how to account for it, and that there is a partial form (_form.haml) that both the edit.haml and

What is the most elegant way to save new one-many associations? order = Order.new(:name => "My Order") order.line_items << LineItem.new(:product_id => 1, :quantity => 2) order.line_items << LineItem.new(:product_id => 2, :quantity => 5) order.save The above - which is by far the most elegant way of putting it - doesn''t work for me - the line_items

Hi all I''m creating a shop page. I have a cart model that looks like the following: class Cart attr_reader :line_items def get_line_item id @line_items.each do |l| return l if l.id == id end end def initialize @line_items = [] end def empty! initialize end def empty? return true if @line_items.empty? false end end And I have some

Hello everyone, I''m fairly new to Rails (writing my first real app) and brand new to this mailing list. I''ve got a rails/sql error I just can''t seem to solve. It''s probably really simple, but I''m been googling and reading for a day and have made zero progress on it. Hopefully someone on this list can shine some light on my problem, or point me in the

I am following the instructions on Agile Web Development with Rails book "Iteratio E1: Capturing an Order" section. When I run the migrations I get the following error. rake db:migrate (in /Users/balaparanj/work/depot) -- execute("alter table line_items \n add constraint fk_line_item_products \n foreign key (product_id) references products(id)") rake

I am fairly new to Rails, and I am having difficulty in forgetting the old way of developing and using the Rails way. This is my question, using orders and line_items as an example. An order has_many line_items A line_item belongs to order In my OrdersController I have def summary @orders = Orders.find(:all) render :xml => @orders.to_xml() end What I want to achieve is to

Hi, Is there a concise/ruby way to do the following: [Note: 1 and 2 below are not related.] (1) for p in 0...@order.line_items[k].shipment_lines.length shipline_qty = shipline_qty + @order.line_items[k].shipment_lines[p].quantity end (2) ts = Array.new for tk in s.trackings ts.push(tk) end

Hi all, Hi, When I want to compute the eigenvalues & eigenvectors of a specific matrix, R crashes (i.e. it stops responding to any input). I've tried it with different versions of R (2.1.1, 2.2.0, 2.2.1) - all with crashing as result. What I did before the crash was: M <- as.matrix(read.table("thematrix",header=T)) eigen(M) If, instead of eigen(M), I use eigen(M,

Hi ! I just have a simple question. I am writing an app using rails to familiarize myself with the framework (which is pretty cool, by the way). I just wanted to know why these two work differently (since "find" should be a synonym for "detect" according to the Pick Axe) : current_item = @invoice.line_items.detect {|i| i.product.id == key} current_item =

Hi all! I need your help. My server doesn't respond any more. Everything crashed. How can I find out if this is a bug or it is simply overloaded? I don't have much running, just KDE with about 10 programs on each of the 16 desktops, and a few background processes. This seems much, but I often have much more stuff running, and it is not even slow. It does respond when I ping it, but

I am writing a banking / accounting / bookkeeping system for myself. I have orgs (who pay me or who I pay) and line_items (day to day transactions that mirror the entries on my bank statements) On my line_items screen I have a select box with various orgs in it. I''d like to have a way to add an org write there on that screen rather than have to leave it and go back to the orgs

Hi, I''m using acts_as_ferret in my rails application and I''d like to use more_like_this to retrieve some ''similar'' item suggestions. I have a class ''items'' which has a status field and I need to retrieve items that only have one of the two possible statuses. Looking at the more_like_this method indicates it supports an :append_to_query

Hi, I want to make a copy of an object with its associations, and I am looking for an elegant solution. This is what I intuitively think should work, but it doesn''t: order2 = order1.clone order1.line_items.each do |o| order2.line_items.build(o) end This doesn''t work because a model class does not stringify its keys ... so I can''t pass an object into a method that

Hi, I have a real simple association setup here that''s just trying to: - Create a new PayjunctionOrder - Create some LineItem objects and assign them to the PayjunctionOrder - Save everything I''m using Rails Edge. ---- class PayjunctionOrder < ActiveRecord::Base has_many :line_items end ------------------ ---- class LineItem < ActiveRecord::Base belongs_to :order,
