similar to: <% unless params[:context] == :gallery -%> question

Hello. I''m using the Agile Web Dev. book 1st Edition and I''m puzzled by the code on pp. 83-84. <%= link_to ''Add to Cart'', {:action => ''add_to_cart'', :id => product }, :class => ''addtocart'' %> def add_to_cart product = Product.find(params[:id]) @cart = find_cart

I am trying to do a simple search by product name. The first page returns fine, but when I try to go to any other pages of the search results, I lose the original search parameters from my search form and get NilClass errors. Here is the code in my controller: namesearch = "%" + params[:name].strip + "%" @product_pages, @products = paginate :product,

I have some code working that lists only items from a particular user. The code in my list action finds the user and then conditionally lists only his/her items: def list user = User.find(session[:user]) user_id = user.id @product_pages, @products = paginate :products, :per_page => 10, :conditions =>[''user_id = ?'', user.id]

Hi. I''m doing a tutorial from the Thomas~Hansson book and am getting this error message: Extracted source (around line #17): 14: <%= link_to ''Add to Cart'', 15: {:action => ''add_to_cart'', 16: :id => product }, 17: class => ''addtocart'' %> 18: </br> 19: </td> 20:

I keep getting this error every time I try to pass a value to a method. Here is a sample nonworking method. I''ve been pulling my hair out over this all night! Why won''t it work!? My url path is :3000/store/browse/shoes and I''m getting this in the log Parameters: {"action"=>"browse", "id"=>"shoes",

I''m trying to grab a temporary variable from my view and then pass along that value to my model My view code is this: <td width="40" align="center"><%= text_field ''product'', ''qty_added'', {:size=>3} And I''m trying to pass the qty_added variable to my model. item.quantity = qty_added It doesn''t seem

Hi, I am trying to use the update_attributes on object with nested attributes and I am getting the following error: ProductPrice expected, got HashWithIndifferentAccess Here''s the situation (simplified): class Product < ActiveRecord::Base belongs_to :productPrice end class ProductPrice < ActiveRecord::Base has_one :product, :dependent => true

I''m messing with the agiles store example. I added a field in my product table (user_id) that is also a foreign key relationship via fk_products_user In my scaffold I''d like to list the products as usual, but only those products from the logged in user. I assume that would be done in the controller.. How would I extend the basic controller: def list @product_pages,

In my database I have a products table that has a bunch of attributes (title, description, etc) including one for date_expires. Is there a best practices method to get the database to erase the expired items? Is that done outside RoR via Cron or something? Else is it better to just have my app filter out anything that is expired but still keep those records in my dbase? -- Posted via

Using acts_as_ferret I''m trying to do a query like: active:(true) title|body:(#{params[:s]}) product_price:( >= #{params[:min]}) Where I want to return only the active products that contain the search term in the title or body and has a minimum price >= params[:min] I''m finding that even though I''m indexing the product price as an integer (so no .00 to cause

Hi I am new to the whole Rails/Ruby world as having come from a MS .NET background, but I have followed the Depot example in the Agile Web Dev. with Rails book with relative ease. However as an exercise to see how much I had understood, I thought I would attempt to modify the example a bit and add a Quantity field to the store index so as to pass that value into the cart. I have extended the

I would like to write a fast version of a function which contains slow loops that I cannot vectorize. I would like to rewrite it in C, but in the loops I need to call a few (two) R functions. Which is the best way to do so? I have read that one can call a C library which import all the R functions (R.h, is it?). Is that efficient? I tried to have a look into the internal C code to find just the

Hi. I copied parts of the ajax-examples in Agile Rails prog. and modified it so it searched for zip-codes. The result is displayed in search.rhtml. The first version looked like this, I liked the look of the "add to cart" in the depot-example. :class => ''button1'' is originally addtocart which I renamed in the .css-file. <% for city in @cities %> <%=

I have an app that has two models -- products and details. I''m building a form that allows a user to create a new product and specify a description, etc. The form needs to allow for creation of multiple items in the details model/table. for example, I have a block of form items that collect info for the men''s version of the product -- inventory count for each size, etc. And
