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

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,

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

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

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>

So I''m updating multiple model objects in one go with something like this in my controller: => Photo.update(params[:photo].keys, params[:photo].values) When the update fails due to validation errors, how do I detect it? The Rails API says: "If the save fails under validations, the unsaved object is still returned." So I can''t simply do this: => if

In a belongs_to association, is there a way to tell if the associated object was newly created? Hopefully this will explain my question: A Firm class declares has_many<http://api.rubyonrails.com/classes/ActiveRecord/Associations/ClassMethods.html#M000530>:clients and a client class declares

Instead of save every time there's a new element in the cache, batch the saving to disk every 100 changes, saving the unsaved remainder at the exit. While not a big optimization, this reduces a bit the disk usage during generator run. --- generator/utils.ml | 14 +++++++++++++- 1 file changed, 13 insertions(+), 1 deletion(-) diff --git a/generator/utils.ml b/generator/utils.ml index

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.

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.

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
