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

Hello People, I have a possibly very lame question. I am fairly new to RoR, and I want to make sure I do it "right". I have a model called Invoice, and one called InvoiceLines. Usual story: the table "invoice" has a 1:n relationship with "invoice_lines", which includes invoice_id. Now... the application will have a "new order" button, which will allow

Hi I''m not too sure how best to explain this but here goes! I am trying to write an appointment system. I have, through example, just about got the dynamics correct. Even tried to play with some table joins (and excuse me if I''ve used the incorrect terminlogy). But no matter what I try I can''t seem to get the following code to work.

I am using this line on my index.rhtml page to capture the quantity required of a particular item for a basic shopping cart app: <%= text_field ''line_item'', ''quantity'', {:size=>3} %> </td> but my next screen (a cart screen) doesn''t reflect what was entered in that text field when the item is added to the cart. That is,

Hello, I have a model called invoice and one called lineitem. An invoice has_many lineitems, and an lineitem belongs to an invoice. I have a model method that calculates the price of a lineitem, and one that calculates all lineitems in an invoice.

Let''s assume that I am trying to build an application where the user can enter invoice. In the app the user can add lines items. Each line item has decription, date, rate and hours. When the invoice screen comes up the first time I have one blank row for the line items. <tr> <th>Description</th> <th>Date</th>

I''m having trouble with a validation that depends on an attribute of a belongs_to parent. If the child is added to an unsaved parent (parent.children << new child), the has_many collection parent.children includes the unsaved child. However the belongs_to attribute child.parent appears to be nil until the parent has been saved. Without access to the parent attributes, the validation

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

Hello again, I have a table called line_items, with the following fields: id int item_name varchar() qty int conditions text I''ve made my LineItem model, and everything works as such (with simple text_fields).. Now I''d like for the conditions field to be a select_tag() with multiple choice possibility. I''m guessing I need some code to expand/restract the array for

What is the best way to get the running total of a number field in child records. Let say I have an Order model, which has_many :line_items, and each LineItem has an amount field. I would like to get the grand total of a specific Order. Is it a good idea to add a ''total'' column in the ''orders'' table and update it every time a line_item is

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

Given this code (which renders rjs), I''m faced with the fixture- driven way of spec-ing or mocking. How the heck to you mock this so the code at line (2) and (4) work right? I''m still struggling with mocks but it seems like this can be done. Forgive the naivety of this question. 1. def change_quantity 2. @line_item = LineItem.find_by_id(params[:id]) 3. unless
