Hi, I''m having great fun developing with Rails but I''ve come to a problem that I can''t quite figure out. I have an Order object that "has_many" order_lines. This works perfectly and I can see all the lines. The OrderLine object has an order_id field as well as product_id and amount. Now ideally I would want to do : order.orderline[0].product.name for example to pull back the name of the product it''s linking to - but no matter what I try, I cannot get that to work. Can anyone tell what I''m do...

I wanted to use ARTS to add RJS in a behaviour driven way to my application, but I''m having some trouble asserting a replace_html with a partial. I''ve created a pastie (http://pastie.caboo.se/60694) which contains the RJS I want to spec, the spec which I already wrote and its failure message. I''m currently using RSpec-0.9.2

In part of my application I''m using dynamic tables. I''m aware of the single thread conditions. I''ve tackled some caveats yet - will post a blog about it soon - but there''s one I need help with. Consider 2 models that are associated: Order and OrderLine where Order has many order_lines. Now we set the table names for them: Order.table_name=''v1_orders'' OrderLine.table_name=''v1_order_lines'' Query: OrderLine.joins(:order).where(Order.table_name=>{:customer_id=>1}).all Result: Select v1_order_lines.* FROM...

...invoice Additionally, if there is a position column in the child table, the parent association will be created with an order clause. For example, given a foreign-key from a order_id column in an order_lines table containing a position column, to an id column in a orders table, the plugin creates: OrderLine.belongs_to :ordersOrder.has_many :lines, :order => :position The plugin also supports the creation of has_and_belongs_to_many associations. For example, given the tables product_product_categories with foreign- keys to both the product and product_categories tables, the plugin creates: Produc...

Say I have a model consisting of Order( has_many :order_lines) and OrderLine( belongs_to :order). What would be the ''rails way'' to create an order form? Know I could just say @order = Order.some_order, @lines = @order.order_lines, and use something like this..: order.rhtml: Order no: <%= @order.no %> Date <%= date_select "order", &qu...

...; ) -%> <%= text_field_tag("frozen","", :size => "2", :value => "0") -%></td> <td><%= submit_tag("Order") -%></td> <% end_form_tag -%> <% end -%> The idea is to present the user with a list of orderlines with an "Order" button at the end of each line. They fill in the "Fresh" and "Frozen" values for a line and hit that line''s order button. What appears to be happening is that the submit button for every line tries to submit the data in the "Fresh&qu...

...nothing and all I''ve found is for Arel 1 so I''ve run into NoMethodError: undefined method `[]'' for #<Arel::SelectManager:0x00000003f1b820> errors with join syntax. My query is barely simple but involve nesting queries. I have 4 tables. Assets, Deposits, Orders and OrderLines and I want to get asset name, the stock, the quantity that is ordered and the difference between the two previous. I''ve manage to do it in pure SQL. (tested on postgres) select assets.name, stock, ordered, (stock - ordered) as available from assets join ( select asset_id, sum(q...

I have a main form representing the model, let''s call that ''Order'', and a partial displaying its'' OrderLines. I use the bulk update methods to initialize model objects directly from form data, leaving validation of business logic to the model. As AR likes to write stuff before i do an explicit save, I wrap the whole update in a manual transaction. This works for valid data, but how do i deal with atta...
