Hi, It appears to me that the command: ruby script/generate scaffold whatever money_field:decimal(10,2) will not generate a valid migration.

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, 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

Hi, I''ve got a Rails app working that includes two two classes, etc.: Expense & Vendor.

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, 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, I have a mysql schema with some decimal(20,20) fields. Now, I made a rake db_schema_dump for deployment of my applications on other machines. Rails created a schema.rb with the decimal fields as float. After a rake db_schema_import the fields are just float not decimal. How can I force rails to create decimal(20,20) columns instead of float? Thx. Marc -- Posted via

Can someone please tell me the best approach to adding support for editing MySQL decimal types in rails?

I have a question for our European readers: how common is it to use commas as decimal points in spread-sheet and statistics applications? Is it an inconvenience to require that all data use a period as decimal point? (i.e., 3.14159 rather than 3,14159). We're trying to make our program as foolproof as possible, and would prefer not to give users a chance to have commas as both decimal
