model validation across multiple views
I have a rather complex object with a number of attributes. For a variety
of reasons, I would like one view to create the object with only a couple of
fields completed, then a second and third view to finish all the fields. I
would like the model to validate_presence_of all these fields, since
eventually I need them all there, and I would like each page to validate its
portion of the fields that

Re: rails question
Hi Shelby,
No prob,
You are having trouble b/c you don''t call @festival.valid? before this line:
if !(@festival.errors.invalid? :name ) # => true if name is invalid
I wasn''t clear about it in my post, but ActiveRecord::Errors#invalid? doesn''t actually do validations. It just looks at the associated errors object (which is empty if validation hasn''t

Spec migrations?
Dear list,
I am in the process of writing on an app with is already running. I
need to create a couple of structural database changes for which I use
migrations. However I want to be absolutely sure I do not destroy any
existing data. So RSpec is the way to go! Or so I thought.
1. dropped the test database.
2. create the database.
3. migrate to the version just before the critical migration

Easy way to handle form input without a model class?
I have a couple forms that I''d like to be able to validate and
automatically populate, but it shouldn''t be based on AR. In fact I
often have a bunch of small forms that I can''t really justify writing
a whole new model class for anyway. I''d like to validate the form
input, and then use rails helpers to automatically populate the form
if validations fail.

Override Validation?
Hi all,
is there a way to override the validation methods so as to avoid the
div.fieldWithErrors divs from being created on the redisplayed form?
Many thanks in advance,

SELECT MAX
How does one do a SELECT MAX query in rails? I''ve searched and searched and
tried lots of things with no luck.
I want to implement "SELECT MAX(column_name) from table_name
and have it return the maximum value from column_name. I just need to get
that one value, not the whole object...
Thanks for any ideas...

how to give a form a name
Using a <%= form_tag ... %>, how do I give a form a name, so that I can
reference it with javascript? I sure can''t figure this out from the docs...
Thanks,
Shelby
PS - what I am trying to do is just have the focus in the first form field
when the form is loaded. There has to be an easy way to do this, but I
can''t figure it out...

serialized DateTime objects returning as Time objects
I have a database field called dates in which I am trying to serialize an
array of DateTime objects. When I unserialize them, they are coming back
in as Time objects. I know this, because I am getting errors that say
"comparison between Time and DateTime failed.
Why is this happening? Is there a way to prevent it??
Thanks Shelby

faster? database search or rewriting objects
I''m having an argument with my son :) I have a table with about 1500
objects called entries. I need to do something with about 100 of them
(schedule manually) I say I should just mark them with a boolean when I
have scheduled them. (manual == true) My son says I should pull them out of
the entries table and copy them to new objects (lets call them "manual"

confused about ruby fast C bindings
I am confused about ruby fast C bindings. Does the command:
gem install mysql
install these?
Is this page:
http://www.tmtm.org/en/mysql/ruby/
the home page for these bindings? If so, it gives no instructions about
installing them with using gem.
Wondering if this is all the same???
Thanks for any help...

saving a collection
Reading the Agile book, I can''t find a single command to save a collection.
The save command seems to operate on only individual objects.
Lets say I have a collection that I have received from a find_all command.
I want to go through and change some attributes in various objects in the
collection. Then I want to resave the whole collection back to the
database. I don''t think

Problem with plotting size/location on variation of star/segment plot
Dear R gurus,
I'm running into a problem with some modified segment plots I've coded
using stars(). What I am trying to do is superimpose two series of data
along with radial axes markers in a 2x2 graphics frame. This is working
fine now, except for the hitch: my plots overfill the frame and are not
centered within it (on my runs they always end up looking like they've

moving data from legacy database
I have rewritten a java webapp into rails. The database structure is
basically the same except that:
1) in the legacy app, several of the tables did not use ID numbers,
but relied on other fields as the primary key
2) in the legacy app, there is a join table that uses email address
and category names to do the join, not ID numbers
I would like to move or change this database to match my new
