Scaffold a Plural table w/ No Pluralization in environment
Hi guys,
I have a situation here. I have my project set to no pluralization due
to legacy tables in environment.rb. Now, I have some new tables which
I''m starting to pluralize. When I do a generate a scaffold to this new
table:
script/generate scaffold my_tables table
it seems to work out fine for certain sections like
http://mysite.com/railsapp/new (which also inserts properly to

Table prefix
Hi everybody,
is it possible to override standard RoR table nomination/pluralization
to include a suffix? I have some tables with usr_ prefix but i would use
"real" table name in model naming. For example i have table
usr_accesslogs; in normal use i should create a model called
UsrAccesslog instead Accesslog.
Is it possible to do this??
Thanx

Problem with plurals, migrations?
Hi,
Ruby 1.8.4
Rails 1.1.4
Windows XP Pro
I''m hitting an issue with migrations that I suspect relates to
pluralization. Here''s the migration:
class Hardware < ActiveRecord::Migration
def self.up
create_table :hardware do |h|
h.column :vendor, :string, :limit => 32
h.column :model, :string, :limit => 32

Railers:
Greetings from the low end of the learning curve. I have installed all
the prerequisites on Win32, including a lite MySQL database with a
table in it called Inventory.
Then I run this command line...

legacy database and finder_sql nightmare!
This is my first rails app with a legacy database and I''m having a
terrible time getting the models set up correctly. I have an order
table that has a primary field named order_number. I have a name table
with a primary of item_number. These two tables are liked by the
item_number and the order_number, but not as you might think. If the
order_number is 2500, then each entry in

Separate databases for reads and writes?
Hi all -
New to rails... been reading as much as I can though and have yet to find
a solid answer (although I think I found an unsolid negative).
I''m wondering if there''s a way to split up the reads and writes in Rails
so that pages/actions that don''t need to write can query from a group of
mirrored databases. And my content managers can update a single master.

comparing two databases with Active Record.
I have two databases in SQLite with the same schema. The other
database was populated by an external
customer and then returned. I want to use ActiveRecord to do the
comparison.
I am not sure of the best way to access the tables in each database
with ActiveRecord models. I could
change the connection dynamically whenever I want to switch between
the databases, but this would seem to be clumsy

Connecting to multiple databases
Hi Everyone,
I am trying to connect to multiple databases and followed along the
Recipe in Chad Fowlers ''Rails Recipes'' book (which basically is about
establishing the connection in a subclass of ActiveRecord::Base, and
inheriting all classes in need of this connection from this class)
Chad Fowler says:

Pluralized Controller Names?
If I do:
script/generate controller Photo
I get a controller named photo_controller. OTOH, if I do:
script/generate scaffold Photo
I get a controller named photos_controller. (Note that the controller
name is pluralized).
I realize that I''m specifying the controller name explicitly in the
first case, but it seems
odd to me that the scaffold command generates a pluralized

Legacy Pluralized Table Names
I am connecting to a legacy DB that has some names plural and some not.
I have configured:
ActiveRecord::Base.pluralize_table_names = false
now when i make a table that has an s on the end, it truncates the s.
example:
Table name: foo_bars
Rails command: ruby script/generate FooBars
Response (localhost:3000/FooBars): uninitialized constant FooBar
It works fine with non-pluralized

Naming conventions for models on older database????

I am using RoR for my web development. But Database is already created
(Older database) with its own table name without RoR Specificcations.
Table names are:-
blacklist_patterns

Please tell me.

weird table pluralization problem
When I created a new project and a "equipment" model for an unknown
reason to me rails tried to query the table "equipment" and not
"equipments", does someone know why it did that ?
So I added
set_table_name "equipments"
in the model class and it now works but I don''t really understand why it
is required in the first place...

Active Resource and non default model names
I have a model (accessed restfully) named TranscoderQueue, it''s name
is overridden to ''TransocderQueue'' so it is accessed as ''/
transocder_queue'' as opposed to ''/transocder_qeueus''.
class TranscoderQueue < ActiveRecord::Base

multiple database in the same actions?
Hi,
I read the example in
http://wiki.rubyonrails.com/rails/pages/HowtoUseMultipleDatabases,
it show us how to connect to other database, each time
we start a new action, however, this doesn''t work
while you try to connect to two different database
within the same action.
SO I wonder is it possible to bind to two or more
database within the same action????
Thanks you very much

Overriding Model Name
If I understand things correctly, by default, Rails expects both the
ActiveRecord class name and the model name (i.e., the name of the file
that contains the definition of the ActiveRecord class) to be the
singluar of the table name. How can I override this default behavior
with respect to the model name? That is, I would like to have the
file name of the file that contains the definition of the

Fixtures: pluraly bitten
With my functional tests (on PgSQL) I get strange errors like this

Tracking this down, I found that sequences are only reset for some of
the tables I''m using. The reason? Inconsistent singularization.

Hi List!
May I tap into your combined common sense ?
I have a legacy logging app that needs to be modernized. At the moment,
Data is going to be stored in 5 tables, one table is going to contain

Pluralization of non-noun names
People,
I have an insurance company client and for the last eleven years I have
wanted to completely redevelop their system from scratch. However, the
boss has never been interested in hiring a team to develop the new
system (partly because of the cost and partly because of some famous and
expensive development failures in the industry) and has always insisted
on incremental development of the
