similar to: Simple AJAX question

Dear all, Help me get a simple AJAX behavior right. I know zero AJAX, thus please advice. Below is a simplification of the real code and I hope I can describe my intention clearly. class StoreController < ApplicationController def show_cart @cart = Cart.new @new_item = CartItem.new end def add_item @new_item = CartItem.new(params[:new_item]) if

I bought the second edition of the ruby on rails, it seems to work fine now, did some adjustments to the code. But now I get a second error and I want to learn to understand to fix them myself. So here is the error. ArgumentError in StoreController#add_to_cart wrong number of arguments (1 for 0) #{RAILS_ROOT}/app/models/cart.rb:15:in `initialize'' #{RAILS_ROOT}/app/models/cart.rb:15:in

I''m trying to provide our customers with a page where they can add up to 20 items to their cart in one form. The form simply has 20 rows with each row containing a text input for product code and a text input for quantity. I''ve tried having the controller create an array that has an object for each row by looping through something like: @new_items[1] = Cart.new and the

Hi - another question, sorry.... I''m trying to get the highlighting effect to work on the current_item. The page refreshes fine, and then I get an error as the highlighting code is fired: page[:current_item].visual_effect :highlight, :startcolor => "#88ff88", :endcolor => "#114411" The error

The question is, should we deal with Controller and Action logic in the RJS file? If so, is it quite "spaghetti-like"? This is actually for the Agile Web book Shopping Cart example: If the user clicks "Remove Item" and we do it the AJAX way, what if we want to first show the cart''s content as 0 x Pragmatic Version Control $0.00 and then highlight

I am really new to Ruby and Rails but as you probably see I am trying to get the shopping card working from the book. I am getting this error but I really don''t know what to do. I have looked up several of topics that stated the same problem but as far as I am, nothing has helped me out yet. Is there something wrong with the Product model? This is in the StoreController and I believe it

Good day. Currently I have a system that will successfully add a row to a table. Each row in this table will represent a new product being added to a purchase order. The user can enter a quantity and then select a product code. The product code is the auto_complete field. This field works. However, once the user selects a product code then the values for the product description, buy price, and

I have the following view template: <%= form_remote_tag :update => "new_item", :url => {:action => ''create''}, :before => %(Element.show(''spinner'')), :success => %(Element.hide(''spinner'')) %> <div id="new_item"> </div>

Hello all, First off, thanks for the great work. I have recently added "more submenus" to a functioning advanced menu that only had one "submenu off of the main menu before" The addition of the new submenus has caused the main menu to not function correctly and I have been pouring over the code for several weeks and I just cannot see the error that I have introduced. This

This is kind of frustrating (but no doubt helpful in the long run) that after following along and coding , and d/l the code the same error is appearing. For those who are familiar with the depot app, I''ve run into a problem after fixing the cart to reflect quanitites. I worked through the intended error messages but now have this appearing: SyntaxError in StoreController#add_to_cart

Good day. I have setup of a text field with auto complete and I need to grab the value from that text field and pass it into a method to update a row in a table. Here is the view: <tr> <td align="center" colspan="6"><%= text_field_with_auto_complete( :product, :product_code ) %></td> </tr> <tr> <td

When I add an item to the shopping cart, I get an error: undefined local variable or method `cart_item'' for #<#<Class:0x3715a78>:0x3715a48> Session info says the cart being updated properly. I''m just not able to output two variables: <%= cart_item.quantity %> &times; <%= h(cart_item.title) %> I did some research, and I can grasp that local

HPA, I believe I've found a possible bug with /menu. This against the unmodified -pre5 snapshot. SRC: http://www.survivaldisk.com/menutest.c COMPILED: http://www.survivaldisk.com/menutest.com It's easiest explained if you just compile the .c and experience it for yourself, anyways. If you have two submenus nested within each other and then call a third menu it will bring up the

Hi all, This is a proposal for supporting keyword arguments to Sizer#add following the thread below : http://rubyforge.org/pipermail/wxruby-development/2008-March/001244.html After a deeper look at lib/wx/keyword_ctors.rb and lib/wx/keyword_defs.rb, I understood the whole thing :-). I just reused and modified slightly the method args_as_list. The new Sizer#add_item combines the features of add

Hi all - I''m working my way through the "depot" tutorial. I''m having a problem with the section where the cart contents are displayed on the order page. The cart contents display fine after I add an item to the cart, but simply does not show up on the order page. Any help would be appreciated. I''m running Locomotive 1.0.0c on Tiger with MySQL from

In Depot, the demo application in the the Agile book, actions that modify the model such as add_to_cart redirect to another action that has a clear view role, like index, or show_cart, instead of generating the view themselves. This uses an HTTP redirect that goes to the client and returns. Is this an idiomatic way to design the flow in Rails? -- fxn

I''m adding a web service to a small Rails app that I wrote to learn the framework. This is my last piece of the puzzle and I''m having trouble figuring out how to debug it. I was attempting to iteratively develop the web service method using TDD. There''s so much coercion and stuff going on via the ActionWebService framework that I''m looking to fall-back
