Hi All, Inside my app\views\expenses\new.html.erb file, I had the code: <% form_for(@expense) do |f| %> [snip] <p> <%= f.label :vendor %><br /> <%= f.text_field :vendor %> <br /> <div id="vendor_droplist> <%= select_tag "test", options_for_select(@current_vendors.collect { |v| v.nickname }), {:multiple

I''ve got two entities created by scaffolding: Expense & Vendor In Expense#new there''s a form with a Vendors-drop-down and a NewVendor- button. The latter button brings up Vendor#new. The Create button in Vendor#new brings up Vendor#show with Edit & Back links. I want to append a third link conditionally to Vendor#show: if the Expense#new form led to the Vendor#show

Hi, I''ve got a public\images\DownArrow.jpg and app\views\expenses\new.html.erb that want to present this image in the following context: <p> <%= f.label :vendor %><br /> <%= f.text_field :vendor %> <%= f.image "DownArrow.jpg" %> <br> <%= select_tag "test", options_for_select(@current_vendors.collect {

Hi All, I’ve got a few versions or Rails installed and I''d like to run an App I’m developing with various versions of Rails. I heard of two ways to switch the version of Rails that an app uses: 1. Use GitHub as described by http://kylecordes.com/2008/04/30/git-windows-go/ . But that requires using Bash in a Command Window and more steps than I want to go through. 2. Alter

Hi, I''ve got a Rails app working that includes two two classes, etc.: Expense & Vendor. I eventually learned that the mental concept I had of their relationship should be express in Rails as: class Expense < ActiveRecord::Base; belongs_to :vendor; end class Vendor < ActiveRecord::Base; has_many :expenses; end

Hi, Then RSpec 1.4 recommends, in the webpage http://rspec.info/documentation/expectations.html, referencing the subject items. I''m running ruby 1.8.6 (2007-09-24 patchlevel 111) [i386-mswin32] over WinXP-Pro/SP2. I believe I installed RSpec with a Ruby gem. At least, I think that''s confirmed because I have a lot of stuff in the directory K:\_Utilities

Hi All, I just created a new CRUD "expense" (using Rails 2.3.5 scaffold) which included "amount:decimal". When I: 1. populated the amount field of a new expense with 5 characters: 12.50 and 2. saved the new record I got a display of the new record that showed Amount to be merely "12". I clicked Update and put my cursor over the data field for Amount and got a

Hi, It appears to me that the command: ruby script/generate scaffold whatever money_field:decimal(10,2) will not generate a valid migration. Therefore it appears to me only two ways to achieve the desired result is: 1.1 Omit the the precision/scale on the scaffold command 1.2 Edit the migration file by following the "do |t| ... end" with the command: change_column :whatever

I need to be able to merge a lot of content for web pages, along with links to other pages taken from a list of categories. The text that goes with each category can be different depending on the context that it''s displayed in. I could do this by having a whole stack of *.html.erb files which hold the static content and access the Rails helpers to pull in stuff from the database and

Hi All, "We''re sorry, but something went wrong." is the message I got when I started up an RoR app in the environment: Rails 2.3.5 Ruby 1.8.6 WinXP-Pro/SP3 Firefox 3.6 MySQL 5.0.37-community-nt Mongrel The app under development was working fine until I (stupidly) thought I needed to upgrade MySQL to 5.1.44. I took the precaution of MySQL-dumping the development db before

Hi All, I''m running: WinXP-Pro/SP3 Rails 2.3.5 MySQL 5.0.37-community-nt I ran rake db:create:all and got something like: LibMySQL.dll required. I had a worse symptom previously when, on an earlier post on a related failure, Sharagoz kindly suggested I drop back to a 5.0 version of MySQL. As I prepared this post, I wanted to recall my version. In particular, I wanted to run select *

Hi All, I''m running: Rails 2.3.5 MySQL 5.1.44 WindowsXP-Pro/SP3 Following Noel Rappin''s book, Pro RoR, I successfully got past the point of creating my first scaffold: ruby script/generate scaffold supplier nickname:string qbname:string That produced the migration, 20100221011210_create_suppliers.rb: class CreateSuppliers < ActiveRecord::Migration def self.up
