primary_key_prefix_type, support for non-integer primary keys
Hello!
I''m just starting out with Rails--and Ruby itself for that matter--and
have a couple of questions regarding primary_key_prefix_type and
non-integer primary keys.
I see in the ActiveRecord documentation [1] that by default the primary
key of a table "foo" is expected to be "id", though
primary_key_prefix_type this can be changed to :table_name or
:table_name_with_underscore for "fooid" and "foo_id"
respectively. I''m
unclear where to set this or the syntax I should use. My attempt has
been to add code to environment.rb things such as
ActiveRecord::Base.primary_key_prefix_type :table_name_with_underscore
or
def
ActiveRecord::Base.primary_key_prefix_type()
:table_name_with_underscore
end
or even
def
ActiveRecord::Base.attributes = (primary_key_prefix_type =
:table_name_with_underscore)
end
The first two give me syntax errors, while the third presents me with
Method Not Found.
I''m sure the above code is clear evidence of exactly how much I have to
learn :) But I''m looking forward to it.
The docs also mention that primary_key_prefix_type is a global setting.
Does this mean that this attribute will affect all ActiveRecords in all
apps on the installation or just the ActiveRecords for the app it''s set
in? Knowing where to put this attribute setting will make it clear, I''m
sure. I can currently work around this using def self.primary_key() :
I also am interested in using non-integer primary keys, in particular
for things such as localization script codes where I''d rather use
"en_US" or "ja_JP" for the primary key than tack on another
column. The
only mention I''ve found of non-integer primary keys is in the
ActiveRecord changelog entry for 0.8.3. I''d be grateful if someone
could point me someplace where I could learn more about this and how to
use it.
I''ve googled quite extensively, and I know there''s a lot I
still need
to learn. Any hints or pointers to where I might find more information
and examples are greatly appreciated.
Thanks!

Greetings All! Now that I seem to have gotten my head around whats going on with rails (at least enough to consistently create the default app, LoL) , I want to play around with some of the the other gems to enhance my web app, things like crypt-based auth and the redcloth package, for instance. So, it would be usefull for me to be able to read the documentation for these things; I cant seem to find out how for the life of me. I''d like to be able to examine doc for uninstalled or not yet installed packages, and to read doc for installed packages as well. This is probably something so simple I''m missing the obvious; if someone could drop-kick me in the right direction I''d really appreciate it :) Cheers, Twitch

Is there a way to use a different layout for certain actions inside a controller? -- Ben Sinclair ben-bgLzOLc97kcYkl5+HhvCNA@public.gmane.org

Ben, By default the layout is defined by the [action_name].rhtml file in app/views/[controllername]/ (unless you''re using scaffolding), so it is exactly what you make it be. Thus, by default the actions are not sharing any layouts. If you then *want* the actions to share a layout, you might want to take a look at rails layouts: http://rails.rubyonrails.com/classes/ActionController/Layout/ ClassMethods.html //jarkko On 28.1.2005, at 16:45, Ben Sinclair wrote:> Is there a way to use a different layout for certain actions inside a > controller? > > -- > Ben Sinclair > ben-bgLzOLc97kcYkl5+HhvCNA@public.gmane.org > _______________________________________________ > Rails mailing list > Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org > http://lists.rubyonrails.org/mailman/listinfo/rails >-- Jarkko Laine http://jlaine.net http://odesign.fi _______________________________________________ Rails mailing list Rails-1W37MKcQCpIf0INCOvqR/iCwEArCW2h5@public.gmane.org http://lists.rubyonrails.org/mailman/listinfo/rails

I''m not sure if it''s just my understanding of layouts or what, but I was a bit confused by the following:> By default the layout is defined by the [action_name].rhtml file in > app/views/[controllername]/ (unless you''re using scaffolding), so it is > exactly what you make it be.It is my understanding that *views* are defined by the action name by default, and that there is no layout by default. In other words, a layout is a special kind of view that is can be shared across several actions or views if explicitly made to do so. For example: class MySpecialController < ApplicationController layout "default" ... def list ... end end The ''list'' action will by default render the /app/views/my_special/list.rhtml view, but because there is a "layout" directive in the class, the layout in /app/views/layouts/default.rhtml will be called first, and the contents of list.rhtml will be placed wherever the <%= @content_for_layout %> variable is found. I hope this helps! Duane Johnson (canadaduane)
Actually there is a layout by default: app/layout/[controllername].rhtml (if it exists) Duane Johnson wrote:>I''m not sure if it''s just my understanding of layouts or what, but I >was a bit confused by the following: > > > >>By default the layout is defined by the [action_name].rhtml file in >>app/views/[controllername]/ (unless you''re using scaffolding), so it is >>exactly what you make it be. >> >> > >It is my understanding that *views* are defined by the action name by >default, and that there is no layout by default.

I am not sure about what you are needing but I have something like:
class MyController < ApplicationController
layout :select_layout
(all methods go here)
private
def select_layout
[ ''index'', ''list'',
''view'' ].include?(action_name) ? "site" :
"user"
end
end
So depending on the action being called, i can use a different layout.
This works with newish Rails versions (didn''t work with my 0.9.3 but
since then I am using EdgeRails ... living on the edge is good).
Just my 2 cents.

I wasn''t sure at first if Ben meant layout in general (as a web design term) or RoR Layouts. The latter turned out to be the case.
