A bug in sweeper.rb? [was: A frustrating and strange error when config.action_controller.perform_caching = true]
I fired up the debugger and watched the code happen tonight.
The problem occurs if the config.action_controller.perform_caching = true in
your environment. It''s not set to true in development but it is set to true
in production and staging.
The problem occurs not in my controllers but in sweeping.rb (part of rails).
Rails calls this code for every controller which was instantiated in

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

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

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...

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...

Problems when using sweepers with postbacks
I''m using a cache sweeper class [1] to take care of some pretty complex
sweeping. However, there is a problem with the current implementation.
Namely, the sweeper gets called only when an action named in
cache_sweeper is called using GET. As many methods where sweeper would
be useful are using postback to send the form to the same action, this
causes the cache to get swept when

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

Cache sweeping and render_component (my mistake or Rails bug?)
Hi
I''m working on a program which relies on heavy cache sweeper usage.
I''ve just bumped onto an odd problem. When using render_component
method in layouts or templates with cache sweeping turned on, Rails
throws an exception with the following message:

You have a nil object when you didn''t expect it!

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

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

Script for removing stale sessions: version for RH6.0? [Offtopic?]
Hello, people at SAMBA list.
I'm going thru the same problem that Nicholas Williams has
described in samba-list first (see references below), and I'm implementing
the solution you've decribed in the list
(SO_KEEPALIVE, etc). But I'm stuck with the script issue, as I run RedHat
Linux 6.0 which doesn't use ksh but pdksh instead. The ksh script doesn't

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

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...

form helpers with non-ActiveRecord objects
I have an ActiveRecord model (called Festival) that contains an array of
"FestDate" objects serialized into a sql text column of the Festival object.
(like the Agile book first edition describes on p. 205)
The FestDate objects themselvs are not ActiveRecord objects. (of course,
otherwise they would be in their own table...)
When working with a Festival, I would like to use various
