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

Button on view
Hi, I have a page containing 3 views (2 are partials). One of the partials needs to have a button that will clear a table called "messages" in the database.

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).

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

Javascript helpers not updating table row in IE6
Trying to replace a table row with an id using both RJS templates and normal link_to_remote :update. Neither work in IE6, fine in FF etc. If I use the same code but target a div with an ID it works. This is tricky as I have a table with edit buttons, when the button is pressed that row gets updated with a partial containing a form for update. I need this to work as II don''t fancy
