Help with DRY: too much code in my view
I''m a newbie to rails, and really to the whole DRY and MVC thing as
well, except where I accidentally fell into things doing it my own way
in the past.
I''ve got a fairly complex DB structure I want to create an interface for
using Rails. Getting simple tables to display, edit, save, not too much
problem there. But where I''m having trouble is figuring out where to

Using Reflections to find out ActiveRecord class association
I want to find out what are the associations with another active record
class. So If my class is as below:
Class Component < ActiveRecord::Base
has_many :branches
end
class Branch < ActiveRecord::Base
belongs_to :component
end
and then I do
Component.reflections[:branches].active_record
I would expect that to be Branch but it is in fact Component.

Dead horse: validates_associated
Regarding validates_associated...
Let''s say I have:
article belongs_to author
But for whatever reason, I want an article to also be written
anonymously and therefore not require an author. Then I have:
Article:
belongs_to :author
validates_associated :author
But I DON''T have validates_presence_of. What I want to do is validate
that an author is valid --if it is

HABTM association with own class?
If I have a class, Asset, which has and belongs to many associated Asset
objects, how do I do this?

Right now, my table has a :first_asset_id and a :second_asset_id, but I

Issue with Arel::SelectManager and insert Method
Hello,
Arel::SelectManager (arel 2.0.9) uses following statement to insert a
new record:
@engine.connection.insert im.to_sql, ''AREL'', primary_key_name,
primary_key_value
But in DatabaseStatements insert ist defined as:
insert(sql, name = nil, pk = nil, id_value = nil, sequence_name = nil)
Actually, Arel::SelectManager does not use the sequence name. This

Assigning to the foreign key on a belongs_to association
I''ve encountered what seems like an odd omission in the behaviour of
belongs_to associations: if you assign to the foreign key attribute,
it doesn''t update the associated object (or mark a previously loaded
one as stale) until you explicitly save or reload it.
Let''s say we have a Company model, which belongs_to :city :

Rails 0.10.1and WEBrick
Doesn''t appear to work with WEBrick. Works find with Apache/FastCGI.
Something wrong in the way Rails is trying to process paths from the
WEBrick server. If I try to send in http://localhost:3000/recipes/new,
WEBrick is interpreting /new as my controller, instead of my action.

Self-referential join model does not work
I have been trying to model a labeled graph using ActiveRecord (trunk
version). Basically, I have a ''Node'' model which represents a node linking
to other nodes. Links (aka edges) are labeled (i.e., have a ''label''
attribute and other behavior). Thus I decided to model edges as an ''Edge''
model and use a ''has_many :trough''

Modifying Conditions for has_many at runtime in controller?
