HABTM: deleting records based on attributes
Hello All,
I am new to ROR, and can''t seem to get HABTM to cooperate entirely...
however I might be abusing it! Before I try a different strategy I
thought I''d ask here and see if I''m missing something simple.
So say Projects and Companies are related. Projects can have multiple
Companies, and Companies can be on multiple Projects. But, the same

ActiveRecord collection_select and has_and_belongs_to_many
Hello everyone, first post to the list and a relative newbie to Rails
development. Done quite a bit of JSP, PHP, HTML, XML etc and thought I would
kick the tires on Rails to see if it can speed up development for internal
applications. Anyway, I am running into a problem that is just driving me
crazy and everything I read on the net doesn''t seem to help. I was hoping

Overriding inheritance_column
I''m putting together a Rails application that will display information
from an existing database. The database has a "job" table that

Single Table Mapping
This is pretty simple, but I must be missing the obvious. I''ve got a
table that''s similar to this:
USERS:
- id int
- username varchar(64)
- password varchar(64)
- role_id int
ROLES:
- id int
- description varchar(16)
I''ve had no troubles doing has_many relationships at all. But I want to
map the user.role directly to the role model automatically (which sounds

Dynamic select box
Hi everyone,
I have a problem. I want to display a different select box wether the
current user is an admin or an user.
So I thought I could do this in my view where my form is displayed :
<p class="form-input">
<%= f.label(:role_id, ''Role:'') %>
<%
if (current_user.admin?)
then collection_select(:user, :role_id, Role.find(:all, :order =>

nested forms and attr_accessable
Rails 2.3.5

Is there a list of html_options for the FormOptionsHelper?

{ :default_value => ''5'' }
(of course, there is no ":default_value")
If the form is being used on a ''create'' page, it should display a

to_model
There''s a number of calls in the Rails source to convert_to_model,
which takes an activerecord object instance:
convert_to_model(object)
Here''s the thing. All convert_to_model does is calls to_model, which
returns self (the ActiveModel instance).
Am I missing something here? Why call a method that returns the same
thing?

STI and type tables?
So by default to get STI, I would have something like:
create_table :items do |t|
t.column "type", :string
t.column "title", :string

But if I want to store those type values in a separate table, such
that I have ...
create_table :items do |t|

Serialized object behaves weird
Hi!
I got a class named EinsatzFilter which I serialized to session. Before
saving to session it works afterwards I keep getting the message:
"undefined method `to_s'' for #<Person:0x38c6ab8>". "Person" is a from
ActiveRecord::Base inherited class.
Code:

Another "I'm I right" question...
I''m pretty sure that there''s a better way to do this:

Re: STI and Joins Broken
I''ve made a inheritance rework some weeks ago that would possible fix
it since it only loads the inheritance support in the class that''ll use
it.
In STI case, it would load only if the class that descends directly
from AR has been inherited and the column specified in the
inheritance_column is available.
People here told me to wait until next release so we can dig into this,

Disabling ActiveRecord "type" column subclassing
Hi! I have a legacy table that has a column named "type" and need to
remove this automatic subclassing by ActiveRecord. The api pages are
vague about this, and I tried
self.inheritance_column = "xtype"
which seemed to get me half-way. In the validate_on_create method, the
value of self.type was my model Class name.
How would you disable this feature?

Serialization of ActiveRecord Instances: No Inheritance Column?
Hey,
I have been looking at ActiveRecord''s serialization code, and noticed
that ActiveRecord::XmlSerializer#serializable_attributes purposely
excludes the STI inheritance column per ``options[:except] =
Array(options[:except]) | Array(@record.class.inheritance_column).''''
Is there a particular reason for this? Would anyone be opposed to my
