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

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 new.haml views use (app/views/line_items). My spec keeps failing and...

Please can someone show me the correct syntax for a hidden field in forms, this is my code <%= start_form_tag :action => ''create'' %> <div class="form1"> <table width="auto" boader="8" cellspacing="5" cellpadding="5"> <% hidden_field ''line_item'', ''client_id'', :value

Hey all, I''m trying to find a simple way to reference all of the objects that belong to their parent''s parent. In other words: Clients --> Orders --> LineItems How do I get all of a client''s lineitems in one array (i.e., client.all_lineitems)? Thanks! -Neal -- Posted via http://www.ruby-forum.com/.

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 include a count of line_items per order, and to include it as say total_...

Hello, I am trying to write a sample application. I have class LineItem< ActiveRecord::Base belongs_to : order end && class Order < ActiveRecord::Base has_one :line_item end Now in the controller i am trying : def add @ord = Order.new(params[:ord]) @ord.line_item = LineItem.new(params[:lineitem]) if @ord.save redirect_to :action => ''list'' else render

...9;'}, {''description'' => ''line b'', ''cost'' => ''200''}]. I can''t find the correct naming convention for the textboxes to produce this data structure in the controller. I have tried: <%= text_field_tag("line_items[0][description]") %> <%= text_field_tag("line_items[0][cost]") %> <%= text_field_tag("line_items[1][description]") %> <%= text_field_tag("line_items[1][cost]") %> which results in a hash of hashes: "invoice_default"=>{"0&quo...

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 don''t get saved.

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 Thanks.

Hi, Am relatively new to the RoR world. My question is quite simple. I have a query like such: shipmentNumbers = Order.find_by_sql(["select distinct s.id from orders o, line_items li, shipment_lines sl, shipments s where o.number=? and o.id = li.order_id and li.id = sl.line_item_id and sl.shipment_id = s.id", number]) The above query works fine. I wanted to do the same query using the query below: shipmentNumbers = Order.find(:all, :conditions => ["number...

I developped a web site with Ruby on Rails, but I get a problem during the testing. I have a parent table called "orders" and a child table called "line_items". I created some data for the test in the files "test/fixtures/orders.yml" and "test/fixtures/line_items.yml". In the file "test/unit/order_test.rb" I wrote some code to test the "Add", "Update" and "Destroy" for my model"Order...

I am struggling with how to add dynamically add form elements to a form based on user action. Now here is my situation: I have model Project that has_many line_items On the form to create a project I initially display form elements (some drop downs and text boxes) for adding just one line_item. There is also a button or a link on the page (not sure if this should be in the main form or outside). One the user selects that button/link I need to add another s...

...mple 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 = @invoice.line_items.find {|i| i.product.id == key} (The details of my project are irrelevant, I think.) The first one works, the second doesn''t. With the "find" variant, I get this error : "Couldn''t find LineItem wi...
