I'm looking at creating an application utilizing ROR and the Google Maps API. I came across this book "Beginning Google Maps Applications with Rails and Ajax: From Novice to Professional<[link]>". Would this title be to far out of date to even be useful?

is it safe to allow mass assignment of associations?
Wed, 21 Jul 2010 05:34:01 UT
Item belongs_to :user attr_accessible :user is this safe? Item.user_id is still protected, and Item.user can't be set by mass assignment from a web request because the parameters are all strings - trying to assign a string to Item.user raises AssociationTypeMismatch. Even setting params['item']['user'] to an

The business side of my current situation isn't shaping up as I'd envisioned and so I've started looking for my next adventure.

Wed, 21 Jul 2010 15:14:23 UT
Hi, I have a model "Theme" which has_and_belongs_to_many "Lessons". I need to get the (db) id of the lessons through the theme. For instance, if in irb I write something like this : test = Theme.find(:first) puts test.lessons.first.id I get the ID of test (the theme) and not of the lesson. Do you know how to get the id of the nested object instead ?

Even IDE s have problem with named_scopes. I don't think RDoc can recognize it. Besides looking like a train wreck, that's one of the reason I don't like named_scopes.
all custom helper modules being made available to all controllers without a call to helper?
Mon, 19 Jul 2010 21:30:00 UT
I have three different helper modules in my helpers directory (authentication_helper.rb... etc). In my views and partials I have calls to them but application_controller never directly calls the method #helper directly (as in helper AuthenticationHelper or helper :layout)... Shouldn't calls to those methods return a method not found error

This should be a many_to_many relationship, because one author may be born in the same city where the other author dies. Now in the authors-table, one city_id would not be enough, it has to
