Problem with alias_method in a plugin
Hi,
I''m doing my first plugin, based on attachment_fu structure. Here''s
the code: http://pastie.caboo.se/200797.
The problem is that the meta_tag method doesn''t seem to be
overwritten.
I can call model_instance.original_meta_tag and it return same thing
as model_instance.meta_tag, so the aliasing works.
I can call model_instance.foo and it correctly returns class of

Corrupt index and segfaults with heavy writes?
Hi everyone,
We''re running a fairly heavily used Rails app that uses ferret (and
acts_as_ferret) for search. We''re running on mongrel+Apache, Ruby
1.8.4, and ferret 0.10.13. We''re indexing a handful of attributes on
our "Image" and "User" models.
After the system has been running for several days, the index gradually
becomes corrupted, and ferret

DRYer controller specs
So, I''ve been following the recommendations for controller specs here:
http://blog.davidchelimsky.net/articles/2006/11/09/tutorial-rspec-stubs-and-mocks
Most notably: a single expectation per specify block; the setup block
contains only stubs; mock expectations each get their own specify
block. (I''m still using 0.8, so I haven''t gotten the describe/it
goodness yet.)

non simultaneous effects
Hi all,
If I call this function bla:
function bla() {
Effect.Appear('some_element');
Effect.Appear('some_other_element');
}
Both effect happen at the same time. Is there a way to stop this from
happening? I mean, how can I delay the effect on 'some_other_element'
from happening until the effect on 'some_element' is finished?
thanks and regards,

spec template for CRUD?
Hello,
Has anyone already come up with a set of shared behaviours that
someone could leverage when adhering to a CRUD concept, with respect
to controllers?
Relatedly, it would be nice if there were a way to share generalized
behaviour specs.

log:
SQL (0.000000) Mysql::Error: Lost connection to MySQL server during
query: SHOW TABLES
Any suggestions?
Thanks!

yet another rails site - happycarpools.com
I''m pretty much done with a project I''ve been developing to learn Rails,
http://www.happycarpools.com . If you could take a look, that''d be awesome!
Feedback would be even more awesome!
Probably the coolest thing about making this has been seeing how Rails does
*so much* and hardly has any superfluous parts, if any. There are so many

R 1.9.1 Fails to Start on WinXP SP2
I have two computers both of which are running Windows XP SP2. R 1.9.1
runs just fine on one but not the other. Both installations of R came
from the same installation package. When I click on the desktop icon an
hourglass shows up then disappears. Similarly, if I start RGUI the
process shows up in task-manager then abruptly disappears.
Interestingly, I can access R in Excel via the D(COM) Server

Dynamic forms containing collections
Hiall,
I have the following problem: I need to use forms containing
collections (i will call them FCC), and I want to construct them
dynamically, as I need to deal with quite large forms (more than 600
input fields).
The variables @model_name and @field_name contain the proper model and
field names as strings, which is enough for "normal" form input
fields. (i.e. the "if

Strange Problem With Unwanted, Transient Caching
Hello,
I hope somebody can explain to me what''s going on here because I''m
baffled!
In a controller''s action I want to create a new order for a

know, but that''s for another day) I use code like this:
def edit

tired of using defined? all the time
Hi everyone,
It seems like every time I want to evaluate a possibly undefined variable I
have to use defined? to see that it exists first, so I can''t simply have
-- if params[:range_start] > 3
or something like it. I need to have
-- if defined? params[:range_start] && params[:range_start] > 3
I can''t even have
-- if params[:range_start].nil?

model methods
Hello everyone,
In my model, I have

I was wondering if there were any way to define to_s for leave_at in order
to get the same result?
Thanks!

How To Spec Controllers with Finders
Given this code (which renders rjs), I''m faced with the fixture-
driven way of spec-ing or mocking. How the heck to you mock this so
the code at line (2) and (4) work right? I''m still struggling with
mocks but it seems like this can be done. Forgive the naivety of this
question.

2. @line_item = LineItem.find_by_id(params[:id])

DateTimes get converted to Dates in XML-RPC????
Hi all -
I have written an XML-RPC app using action-web-service. Mostly works
well. Except I just noticed that my :datetime types are coming back as
:date types.
That is, when in the console I query the record via Foo.find_by_id(123) I
get back actual datetimes. If I then do it via XML-RPC, fetching that
same record I get back dates (ie. hour/minute/second are set to 00:00:00)
Any ideas?

Bug? find_by_id(nil) returns object just created
Tried to submit a ticket in Trac, but it reported an error...
Doing a Model.find_by_id(nil) after creating an object of type Model returns
that object -- and the next time, returns nil. It should always return nil.
For example,
Step 1. Create an object:
>> Foo.create(:name => "bar")
=> #<Foo:0x2aaaac3ade20 @new_record=false,

'redirect_to' taking infinite loop.
Hi,
The following controller method taking me into infinite loop. Once the

why it is going into infinite loop?
