Hey, I''ve gotten file_column to upload a file, drop it in the dynamic directory, but I can''t display the image, the directories repeat themselves: My model: class Person < ActiveRecord::Base file_column :image_url In my view: <%= image_tag url_for_file_column(''person'', ''image_url'') %> HTML generated is this: <img

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,

Hello, I am trying to put multiple items in one column and can''t seem to get the syntax right. These are images and the image url''s are being pulled from a database. It seems that <tr></tr> is the trigger to go onto the next item. Here is the code from the controller: def list @items = Item.find_all end Here is the code from list.rhtml file: <%

Hi, I need to take a single uploaded image file and save three resized versions of it, a thumbnail, normal and large version. I was planning on doing this in my model by having an array of geometry strings and looping through them, each time saving a new image object resized to the correct geometry. I know that file column does similar stuff, but I would prefer to have a separate database row

Hi, I''m releasing my first rails application and I''d like to have a common menu in all my templates. Do I have to include an rhtml from .rb or other rhtml ? Some sample code pls ? Regards, Fabian

Hi I am running Mac OX tiger with the installed ruby 1.8.2, and mysql5 (I checked that it was running in preference). I tried to run the various fixes recommended in agileweb. I am stuck on page 57, script/generate scaffold... > Could you paste in your database.yml file, from the > "config" folder inside your Rails app?

Here''s what I''m trying to do. I have two divs, one holds about 20 small images of products and the other holds a single large image of one of the products. I''m trying to use the jazzy "new Effect." way of changing images but I can''t seem to get it too work. My script is replacing the image and then making the element disappear. What

I''m trying to have one image fade out and then another slidedown upon completion of the ajax call. I can''t get the timing correct. How do you do it? Here''s what I''m trying (this does not work) <%= link_to_remote(image_tag(url_for_file_column(product, "image_url"), :update => ''right_content'', :url => {

Is there a ruby embedded code replacement for something like this? <a href="#" onclick="window.open(''http://192.168.78.12:3000/portfolio/show/<%= item.id %>'', ''test'', ''width=660, height=500,resizable=no'')"> <%= image_tag item.image_url, :size => ''200x150'' %></a> Thanks, Dan

To make file_column work I have to copy my local variable back to an instance variables like this: <% for product in @products @product = product %> <div class="catalogentry"> <%= image_tag url_for_file_column(''product'', ''image_url'') %></p> This is needed because file_column specifically looks for the instance

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

Hi, I''m trying to use number_to_currency in one of my models, but i''m getting the following error: undefined method `number_to_currency'' for #<Product:0x396d680> Obviously, my Product model can''t access number_to_currency -- is there something I need to do to make it available?

Im trying to show images in my restful application and have finally found what appears to be the source of the problem. When i have the products resource nested in categories as showen below in the first routes file i can see the categories index (/categories). When i add the images to the products resource map as shown in routes 2 i get the error: image_url failed to generate from

Back in 2.1.1 everything was sweet: Loading development environment (Rails 2.3.3) >> include ActionView::Helpers::NumberHelper => Object >> number_to_currency(12.3) >> "$12.30" Then I upgraded to 2.3.2 and: Loading development environment (Rails 2.3.3) >> include ActionView::Helpers::NumberHelper => Object >> number_to_currency(12.3) >> 12.3

Hi all, Apologies in advance if I got this one wrong, I''m still just a newbie ;-) Going through the Apple ADC RoR tutorial it suddenly occurred to me that the ''number_to_currency()'' helper method was not DRY streamlined. Scenario:: The "number_to_currency()" methods options hash works great when I need to dynamically display different currencies when I

I work in the UK and therefore most of my currency figures will be in UK pounds. I realise that to format a number to a currency format I can use: number_to_currency(amt, :unit => "?") but it would be more convenient to set ? as the default currency symbol. What is the best way to do that? Should I edit line 39 of this file:

Any ideas why I would get an error in a RJS helper on view helpers such as number_to_currency. Example: # my_template.rjs page.help_me # my_helper for my_controller def help_me number_to_currency(10) end I have also tired page.number_to_currency but that doesn''t work either. Cheers, Nicholas

Hi Gurus, I have a class, specified in models cart.rb, which doesn''t inherit from anything--it''s just a container class Cart ... I just discovered I can''t call number_to_currency in that class. Any idea how to "include" it in my code? I tried ActionView.number_to_currency without luck. I could kill a few lines of non-DRY regexp code in cart.rb if I could
