Hi all, I''ve created a custom method called checkout in my app. I create an order (which is done my adding products to my "cart"), assign it to my client, and then I head to my checkout screen where I confirm the items and enter their customer order number and complete the order (submit). Everything works great except that it doesn''t display error messages.

Hi, I''m not sure if this is the right place to post this, but please redirect me if I''m posting this in the wrong place. I''m trying to use a method defined in an engine''s library, specifically it is the current_order method from the Spree::Core engine: https://github.com/spree/spree/blob/master/core/lib/spree/core/current_order.rb In my view,

I''m trying to assign a parent foreign key value using collection_select from my child "new" form. The problem I''m having is if I do not make a selection, I get the following error instead of the Rails validates_presence_of error: You have a nil object when you didn''t expect it! You might have expected an instance of Array. The error occurred while evaluating

Hi, I have been reading a lot about this, but I do not manage to do a nice validation. I already managed to save data to the database, to validate a field, to display a "Everything went well" message. I can also display an error message, but the view does not end up properly. This is the form: <% remote_form_for(product) do |f| %> <%= f.error_messages %> <p>

Hi, This is my rHtml page & Corresponding actions & model pages:- ===listform.rHtml================= <h1>Products List</h1> <%= start_form_tag(:action => "add_to_cart")%> <table> <tr> <% i=0 %> <th> Product No. </th> <th> Unit Price </th> <th> Available Qty. </th> <th> Demand Qty. </th>

I am working on a crude first-go-round-in-rails shopping cart and can''t figure out for the life of me the best way to do this. I have a shopping cart that has one page during the checkout that handles the address information, then the next handles the actual credit card information. How do I take the information from the address form and keep it alive long enough to put it in to

I''m toggling a check box via ajax using: application_helper.rb: ............................................................... def toggle_value(object) remote_function(:url => url_for(object), :method => :put, :before => "Element.show(''spinner- #{object.id}'')", :complete

While it was a good move from Rails part to escape ERB <%= %> tags by default, it doesn''t seem to happen to Sprockets as well. The strange bit is that according to Sprockets documentation, it would be just a matter of naming your template as .jst.eco to enable Eco: https://github.com/sstephenson/sprockets#javascript-templating-with-ejs-and-eco Then, extracted from Eco

I am trying to create a record with association. Within the create method, I would also like to pre-populate dependent (has_many) records from a template in the database. The child records are <u>mysteriously rolled back </u> if I insert them in a loop. If I try to insert a single child record, it works.I have read the books and tried to google my way out of this but am at a dead

Hi all -- The simple question is: How do I set different validations for the same Model, when accessed in different Controllers? Here''s the scenario: I have a store/cart app, with a customer-facing shopping cart, and a typical Admin side. The Admin side also has an Order Entry component, where our staff can enter orders received by fax, telephone, etc. Both the customer-facing cart

I have a really horrendous problem with sessions. before_filter :find_cart_from_session private def find_cart_from_session if session[:cart] # if there''s is a cart in the session begin @cart = Cart.find(session[:cart]) # return existing or new cart rescue ActiveRecord::RecordNotFound @cart = Cart.create @cart.save session[:cart] = @cart.id

First of all id like to say hi to everyone from Argentina, im yet another Depot first-timer. Going through the example, i got to the point where my cart finally runs Ajax-based. And there is a line where Dave says, after all the job is done "You should see the cart in the sidebar update. And you shouldn''t see your browser show any indication of reloading the page. You''ve

Many of you probably know the ''depot'' app from the ''Agile Rails development'' book. When the view changes from ''Store'' to ''display_cart,'' a session containing the shopping-cart (:cart) is supposed maintain the ''cart'' between calls, but when the display_cart stub view shows up, I have always ZERO elements

Hello, Im in the process of working my way through the 2.ed of the agile book. As many of you already know, the book goes through the regular development cycle of the Depot application. I have hit a wall when they started talking about the sessions and the exact mechanics of how an item is added to the session. The code looks like this: depot/app/controllers/store_controller: def add_to_cart

Our CEO, Dr. Dan Steinberg, is planning to visit Europe in May. He would like the opportunity to introduce statisticians (and statistically minded people) to data mining, data mining applications and to forefront data mining tools. Our algorithms are probably familiar to many statisticians (CART, MARS, MART, TreeNet and RandomForests), although it isn't necessary to be a statistician to

Hi everybody, I''ve search a lot on google to help me with this one without success. I know that some people had the same problem as I have, but there solutions doesn''t seems to work for me.

I am actually following the instructions/code snippets from "Agile Web Development with Rails" and got as far as page 73 where I did ruby script/generate controller Store index, then edited store_controller.rb to class StoreController < ApplicationController def index @products = Product.salable_items end end and product.rb to: def self.salable_items find(:all,

I have a shopping cart function, and I''d like to set it up to update the cart with AJAX. My AJAX call will return a view that displays the cart items. My question is with regards to keeping things DRY. When the user goes to "view cart", that page needs to display the cart, then the cart display needs to update with AJAX calls when items are added from that page. It would
