Added associations but don't see generated methods
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

How to find/open Spec::Expectations and Spec::Matchers
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

Specifying a decimal field precision/scale with scaffold requires 2 steps?
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

Accessing rails helpers when processing erb snippets
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

How can I disable Rails 3.1's ActiveRecord Query Caching?
Hey guys,
As most of you know, Rails 3.1 introduces query caching for
ActiveRecord. Great change all-in-all, but for those of us with IT
department mandates for using MySQL (yeah, yeah, I know...), it''s kind
of a mixed bag.
I need to disable query caching in a project I''m building based on
3.1. I''ve tried a couple different approaches, both without any
success. I

Getting started w/ Rails 4
Hi. I''m trying to run Getting started tutorial under Rails 4.0.0.beta1
although it assumes it runs on Rails 3. I was able to get rid of all
errors by wrapping post_params here and there, and installing
protected_attributes Gem for attr_accessible to make sense. Post/
comment CRUD works just fine, but I don''t seem to be able to add Tags

Help displaying text
Apologies in advance ...this may be a really dumb question but here
goes.
@formatted_question[:a] contains text with HTML markup. I want to
display it in a field so I can control its vertical and horizontal size
on the page. When it is displayed on the page now, rather than
interpreting the HTML, it is output into the text field as a string with
all HTML tags showing. What am I doing wrong??

Can duplicate "back" browser function in Rails?
In Rails I have a DB Table index.html.erb view. It has 100''s of items.
When I gen via scaffold I get index, show, edit, update, etc view.
But when I page down several pages, use the "show" link and then the
"back" link I do not go back to where I was on the index view.
Instead, I go back to the TOP of the index not the place where I clicked
on the "show"

Decimal fields generated in Rails 2.3.5 act like strings, sort of
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

rake db:migrate debacle
Hi there - I''m a ruby newbie and am stuck on the Getting Started with Rails
app. See output below. Problem arose when I ran the rake db:migrate
command. I also tried the ''rake db:migrate RAILS_ENV=development'' command
