similar to: Migrations problem with Agile Rails book

I recently finished the first part of the "Agile Rails" book. But, the depot doesn''t completely work as it should. I still have 2 problems: I will explain them in 2 threads. The first one is: I can''t destroy products (I can only creat and update them). When I try to delete a product --> http://localhost:3001/admin/destroy/3 I get this error message:

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

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.

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.

Hi, A newbie in the RoR world, I''m already more or less stuck when generating the scaffold for my first tutorial project ...

I wanted to do the same query using

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).

What is the new way to check if a parent has child items? In rails 1.2.6 I did this: if @client.has_line_items? Client being the parent and line_items the children. Now that I have upgraded to rails 2.0.1 (on my way to current :-) ) I am getting this message: undefined method `has_line_items?'' for #<Client:0x7f3b093b01a0> How should I format the query now?
