Want to use a view helper (TextHelper) in a model class
I have a model that deals with HTML and I want to use the
text_helper.sanitize method to strip the HTML of Javascript.
However, it doesn''t appear that I can get easy access to the text_helper
methods from within a model.
Anyone have any suggestions for how to do this?
In general, I think that there are some ActionView helpers which are
generic enough to want to use in a model class.

Thanks for infos.

Getting a model to connect to a different DB
Hi guys,
I''m still finding my feet in rails and I would be really grateful if you
could help me with this problem:
I need to use 2 databases for my application; one for user details and
one for everything else. So basically what I think I need to do is set
the database to the general one as default and then tell the User model
specifically to connect to the user DB.

Rails noob db questions
Hi, I''m trying to get my head around rails, but the documentation seems
sparse at best (and manuals.rubyonrails.com is unreachable from my location
for whatever reason). I''m trying to figure out a few things:
1) The documentation for the magicfields mentions using datetimes instead of
timestamps, which pgsql doesn''t appear to support. What''s the answer in this

Adding model attribute without db field
I need to add an attribute to a model but there is no need to add a
corresponding database field. The model is a child of ActiveRecord and
it corresponds to a table in my DB but when I add it in the usual Ruby
way, I get a ''number of redirects exceeded'' error.
Here is my code;
The model;
class Category < ActiveRecord::Base
attr :status

Attributes for a model which are excluded from DB?
If I want to do this but not save to the database, how can I go about
it?
things.each do |thing|
changed = someotherqueryresult
thing.update_attribute :testattrib, changed
end
Essentially I want to create a collection called things with some extra
attributes that are not saved into the database, as they are just used
for sorting in a view and should not be saved (in fact saving them

Oracle support for rake db:reset
I recently submitted ticket #9240 (1) adding Oracle support for the
rake db:reset task. I don''t consider myself an Oracle expert by any
means, and would appreciate if someone familiar with the database can
take a look and verify that I''m going in the right direction.
Thanks.

Attributes in classes db/migrate or app/models
Hello,
I''ve got some experience in Java, and recently, I''ve begun to practice
with Rails.
One of the things that has surprised to me, after I''ve read some books,
it''s that classes hasn''t got attributes; the attributes are in the files
db/migrate/*. After that, the ORM makes the mapping with de Database.
But the attributes aren''t in the files

I used MySQL as a backend before. Now I had to move to PG since Heroku
doesn''t have MySQL and forces everyone to use their Heroku-PG database.
But PG virsion of Rails works diffidently. I cannot generate a model
without PG server running:

[Question} how best to use attribute driven db with Rails
I designed out a mostly attribute driven database. Originally i was
going to use PHP, but have now decided to use RoR. Being able to use the
built in OR functionality would be nice, but I am not sure how well it
melds with attribute dbs.
If anyone can give me some pointers, I would really appreciate it
(especially since this is my first endeavor and on an important project
as well).

Using Migrations to convert join table to join model
Greetings,
I''m trying to convert a HABTM w/attributes join table in my database
into a join model table in order to utilize the new has_many :through
functionality introduced in Rails 1.1. Here''s the current table
definition:
licenses_user_groups: license_id, user_group_id, usage_notes
Perhaps it was a mistake, but I made (license_id, user_group_id) the
primary key.

code for uploading files to the filesystem instead of db
Does anyone have any standard code for uploading files to the
filesystem?
I''ve got code already for uploading images to the database but I''d
prefer to store the files on the filesystem.
In particular I need to know how to
(a) ensure a file has been selected in the file_field
(b) how to extract the filename from the file_field
(c) how to actually move the file from client to

using rake db:fixtures:load with rspec fixtures
Hi, I''m new to rspec. I have some fixtures in /spec/fixtures. If they
were in /test/fixtures they could be loaded with rake db:fixtures:load.
Is there any way other than a symlink to load my rspec fixtures into
the database with rake? Or, can I cause rspec to load the fixtures
from /test/fixtures?
Thanks,

I'ts not a (db-)model, not controller - so is it a lib?
Hi!
I''m starting a test spike for a small Rails project, that doesn''t have
any database backend. It''s a kind of a (Debian Linux) system

Best Practices: Splitting the "view model" from AR model
All,
I''m starting to see view state information creeping into my model class.
For example, I have text fields in my view that need to be set a certain
way depending on whether or not a checkbox is checked. And while the
values of these text fields ultimately do represent database columns
that are related to the backing AR object, the text_field values also
represent attributes on a

Model from DB generator
Hello all,
Does a generator exist to generate the ActiveRecord model from the
database?
I wouldn''t mind if it generated parent-child relations always as
has_many - belongs_to.
The scenario in my case is a database of about 180 legacy tables,
with a pattern that the foreign keys use (<parent table name>_OID).
These I''d like to wrap in the model as easily as
