best methods for strings and structures?
I'm trying to generate an R interface for a library that's commonly used and
I'm currently writing wrapper functions for file i/o and return an object
(list?) that contains the elements of the C structure. For example, reading
a file that contains:
struct CONFIG_RECORD
{
char coeffs_filename[256];
char species_filename[256];

zx[0].r = 1.0; zx[0].i = 0.0;
zx[1].r = 2.0; zx[0].i = 0.0;
zx[2].r = 3.0; zx[0].i = 0.0;

Overwrite form helper methods and call old ones in new ones?
Hi all
All my forms should look the same, so I think always putting the right
div etc. tags around them is a violation of the DRY principle.
Until now my forms look like that:
<div class="text_field">
<label for="news_item_subject">Subject:</label> <%= text_field
"news_item", "subject" %>
</div>
Now I want the default

return a list of vectors from C?
I've been working on a shared library that will be called from R. The
functions pass several vectors in and out (residuals, parameters, etc) and I
would like to be able to return a list of objects. I'm familiar with return
single objects (vectors, etc) from a C function, but need a little help for
returning a list of objects.
My code so far looks something like:

Executing SQL in rails, and the types of the data returned
Hi,
Every once in while I have to run SQL by hand, in my models mostly. But
I''m wondering if there is a better way of doing it than I do. And, I
have a question concerning types of the fields in the result the query
produces.
First, about the types. In a certain model, to get and return the value
of a boolean function, I have to do:

class ActiveRecordError < Exception
Hi, I noticed that ActionControllerError was recently changed in CVS
to descend from StandardError instead of Exception, to permit generic
rescue clauses to work.
Could this be done for ActiveRecordError, also? That issue was a
head-scratcher for me the other day when I was porting some code to
Active Record.

cached-model broken with Rails 1.1
It looks like cached-model is broken again under rails 1.1. Can anyone
confirm? Note that the exception below indicates it''s trying to treat
CachedModel as the class name of the model, rather than using the proper
class name (which is Entry in this case, and the table called entries).
This is a model using Single Table Inheritance and acts_as_tree, and
worked just fine under 1.0 and

update_attribute works, update_attributes doesn''t, why?
Hello again...
so I narrowed my problem down. For some reason, while using
login_generator, any User object I pull from the DB can be updated one
attribute at a time using update_attribute, but when I try and do
update_attributes it fails every time. Is this a limitation with
login_generator that I don''t know about, or is there a way around this?
I also tried the .update method and

update_attribute and validations
Just in case it saves someone else the several hours of insanity I just
went through, update_attributes will not save unless the model
validations are satisfied, but update_attribute (the singular form)
will save the attribute to the database even if the model validations
would fail!
This appears to be a feature, not a bug

update_attribute with Validation?
Does anyone know of a way to update individual attributes with
validation? update_attribute disables the validation checks in the
record model, so I''m wondering if there''s a workaround for this.
In my application, I want to allow the user to update some or all the
attributes without having to enter :password and :password_confirmation,
both of which are subject to

update_attribute overwrites existing attributes with NULL.
Hmm.
When using update_attribute from within a worker method, it seems that
Backgroundrb inserts null values into all attributes that are not
explicitly set. Is this possible/true?

Consequences of overriding update_attribute to force validation?
I know the debate of whether this should validate has been rehashed
many times. My question is, what are the consequences of overriding
this method to force validation? Will this break fundamental things?
Will it break plugins? Is there a reason not to have a strict
validation option?
In my code I will never use this as I consider it a terribly broken
method, but some gems use it and in one case
