Hi. I get some strange results when using rename_column on a primary key in a migration. It seems like the migration script removes the auto-increment property if you rename a column. This is a minimal example. create_table :foo, :primary_key => :foo_id do |t| t.column "name", :string end # renaming the primary key makes auto-increment disappear. rename_column

For a table "clients" there are city, state, and zip fields. However, for some clients we only have a state with no actual address. The following code throws a "You have a nil object" error when outputting my client list. Is there a way around this, short of writing a specific case for each possibility? <%= client.city + '', '' + client.state +

Hi all, Not completely sure what I''m doing, but I need to get data from another table based on and id. Below is some breakpointer output: irb> @params => {"project"=>{"project_description"=>"point2", "project_name"=>"break2"}, "action"=>"create_project",

Gang- 1. Is there anything in Ruby that handles the .properites files similar to the J2EE application servers. Or do I need to define all of the properties as constants? 2.

Hello All, If I run my unit tests individually using Ruby, they all work correctly. However, if I try to run them using "rake test_units", I get a bunch of error messages. The error messages appear to be caused by rake not loading any of the fixtures into the test database. I am using PostgreSQL on Windows. Does anyone have any suggestions? Many thanks, Bruce. -- Posted via
