#generate a wrapper script for a textmate_ruby - you can call it whatever you like but
#textmate_ruby is clear

rvm wrapper ruby-1.9.2@rails3 textmate

# this will generate a textmate_ruby command for you
# problem with the above is, it's not going use your project specific gemset and ruby
# to do that, edit the file and change the contents to what's below

#I want to create many of a thing in one shot where thing is an activerecord class with 
#validations.  I can use the following where a listofthings is a vanilla ruby class. on 
#valid?  this class calls all the contained object's valid? method.  and a naive save that 
#calls save on each of the contained activerecord objects.  There's some syntatic sugar, 
#methods that hide the underlying list.  This is minimal code for explanation.  
 
#My thing is an activerecord class
#ListOfMyThings is a vanilla ruby class
#thing to note for form helpers to work you need
# _attributes=(attributes) method defined.
