each PC belongs to one venue only) I can use a select() to present venue

''clear_messages'' %>" and have the controller do "Message.delete_all".
But the problem is that the

splitting a story with double-spaced para''s
Quick question - if i want to separate a long string of text, separated
by single carriage returns, into an array of paragraphs, I can use the
following code:
paragraphs = article.content.split("\n")
The "\n" means a carriage return, as far as I can tell.
If I wanted to take text, that had been written using the more common
double carriage returns, into an array of

start_form_tag n00b question
Hi,
I''m wondering if there is any way to specify the id of a form tag with the
start_form_tag helper. I''ve tried playing around with ", id=>"marginForm" "
and also inclosing both the action variable and id variable in curley
brackets. The Rails API doesn''t off much help for a n00b like me. It''s
probably really easy but any help you guys

Eager loading ActiveRecord objects
I have a complex graph of ActiveRecord entities that I want to load with
one big honkin'' join query to avoid ripple loading. It''s for a report.
However :include doesn''t get me all the way there because I want to load
parents of parents (or children of children). I don''t mind doing the

Firefox won''t let me send ''&'' with AJAX!
Hi everyone,
I''ve encountered a HUGE problem, which may not be RoR-oriented, but
there might be a workaround somehow.
See, at this moment, I''m unable to send AJAX requests back and forth
when the information contains an ampersand (''&''). In essence, request is
never completed. The odd thing is that it only happens with Firefox (IE
and Opera works fine).

got this (split(/ /)) from the online pickaxe book at

ActiveRecord find all based on array -- need ids from array
Does anyone know if it is possible to perform an ActiveRecord find by
passing in an array? I would like to be able to do the following:
MyModel.find(:all, :conditions => ["user_id in (?)", users])
The problem I run into is that the returned SQL contains the to_s()
output of the User object, not the ids of those users. Is it possible
to change this behavior? I attempted to

Making a share visible only to members of a group
Hi,
> I want a shared directory to be visible only to the members of a group, and
> to no one else. Instead, a shared directory is either visible to everyone
I tried to realize this by using include like: #include smb.conf.%G
But it did not work correctly. Sometimes the share was visible,
sometimes it wasnt,
and if it was visible, network path wasnt found afterwards.
