Hi. I need to use functions INET_ATON, INET_NTOA for IP address retrieving. Is it possible to make this transparently (without custom SQL for saving, updating and retrieving)?

The documentation states as an example: select("post", "person_id", Person.find_all.collect {|p| [ p.name, p.id ] }, { :include_blank => true }) could become: <select name="post[person_id]"> <option></option> <option value="1" selected="selected">David</option> <option

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

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).

I got this (split(/ /)) from the online pickaxe book at http://rubycentral.com/book/ref_c_string.html#String.split . The problem is, the resulting array

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

I have in my main RHTML <tbody id="account_transactions"> <%= render :partial =>

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).

And how would one do it? Thanks, Paul
