Scaffolding to use has_many and belongs_to ?
What does everyone on this list think about enhancing scaffolding somehow so that a "has_many" relationship will automatically drop the <select> box into the view to reference the "belongs_to" part of the view? I think scaffolding is great but I am always adding the <select> boxes to reference the parent association. Do you think this would be useful? just a

combining two models in one controller/view "set"
I''m going to take another stab at this question (my first one received no replies): I have two models: Author has_many: books Book has_one: author I have two tables: authors id ... books id author_id ... I let the scaffolding fly and it created the CRUD goodness for each model, as expected. However, I want to have only one view/controller "set" for both models; when I

unicorn 3.0.0 - disable rewindable input!
Changes: Rewindable "rack.input" may be disabled via the "rewindable_input false" directive in the configuration file. This will violate Rack::Lint for Rack 1.x applications, but can reduce I/O for applications that do not need a rewindable input. This release updates us to the Kgio 2.x series which should play more nicely with other libraries and applications. There are

Next Record
Okay, I know this will probably be a very easy question. But I am discovering that RonR makes just about everything easy. The problem is, it takes me a few hours to figure out that I can do it the easy way. I need to know how to move to the next record in a database. I want to format my out put in a table. For example, I want a 3 by 3 table. So record one goes in the first cell, record

Introspecting Active Record Associations
Hi, I''m looking into write scaffold generators that will, amoung other things, scaffold active record associations (eg. generate select boxes for belongs_to where you can choose a parent object) for quicker prototyping. But... My question is: Is there anyway of finding out what associations exist from examining the lodel classes themselves or indeed any other way of finding out this

[AR] #{id} namespace visibility used in finder_sql
Dears, [Rails 1.0.0] I''m working with a legacy schema, and around my 20+ models i''ve used some AR constructs. They are based on a finder_sql doing some dirty sql and using #{id} from the ''pivot'' model for extracting data in other tables. like : class Division < ActiveRecord::Base set_table_name "legacy_division" set_primary_key

Any comment on adding #cast and #cast! to ActiveRecord::Relation?
Not getting any love (tender or otherwise) on my pull request<https://github.com/rails/rails/pull/7035>so I thought you folks might like to chip in. What do you think? #cast and #cast! allow you to declare a mapping from generated column names to simplified database column types (i.e. those used in migrations). This way scopes with columns generated in their select lists can also include

[PATCH] replace fchmod()-based heartbeat with raindrops
This means we no longer waste an extra file descriptor per worker process in the master. Now there''s no need to set a higher file descriptor limit for systems running >= 1024 workers. --- I just pushed this out to git://bogomips.org/unicorn.git and it''ll be in Unicorn 4.x. The subset of raindrops used by Unicorn should work on all machines with mmap(2) +

rxml vs rhtml
I have been wondering if anyone here knows which format is faster for your templates? I am curious cause in the near future I may be using some expensive scripts (timewise) and would like to try and squeak out as much performance as possible. Is Ruby like other languages (ASP classic for example) that inccur a penalty by switching between HTML and Ruby Code? Ben -- Posted via

SQL quoting for :order parameter
When I construct a query using variables I do something like this: @users = User.find(:all, :conditions => ["location = ?", location]) I would like to do the same sort of thing in the :order parameter. @users = User.find(:all, :order => ["? ASC", location]) When I try this though I get a SQL error and I see that the items in the array were concatenated together and

Nil column results, possible to ignore?
For a table "clients" there are city, state, and zip fields. However, for some clients we only have a state with no actual address. The following code throws a "You have a nil object" error when outputting my client list. Is there a way around this, short of writing a specific case for each possibility? &lt;%= client.city + '', '' + client.state +

belongs_to and multiple foreign keys
Hi all, I''m confused about how I''m supposed to specify a belongs_to relationship when the table includes multiple columns that reference the same parent table. In my case I have a "schedules" table with "opened_by" and "closed_by" columns, that both reference the "users" table. In theory, they can be two different user ids. table

model with not te be updated attributes ?
Hi List, I have a table that contains several fields that must be initialized when first created, but may not be altered afterwards (when updating the other fields) because they can be changed by external processes. I noticed that the ActiveRecord update commands (even update_attribute) only seem to work by loading the complete record, changing fields that need to be changed and doing a full

Lookup tables and scaffolding
It occurs to me as a missing feature that there''s no way to indicate a lookup table relationship (as opposed to other sorts of foreign key relationships) in Rails and that the scaffolding generator could recognise this lookup and render a drop-down list automagically for the lookup table. Say you have an Address and a State, and the State is a lookup table. In addresses you have

HABTM join table quirk
I''ve been bringing up a good basica framework for applications at work. To give decent security I''ve been implementing the Rails Recipie for Authorization of function calls modeled on the book''s implementation. (Changes for our environment were added..but are minor.) Since I initially let Rails create the join table between two data tables with a HABTM relationship....I

executive: "is rails secure?"
Yesterday, I was doing a dog-and-pony for the head of the company that I work for. He asked, "Is this (a rails application) secure?" I said, "It''s as secure as anything else on the web is," and proceeded to talk about how the data was protected, how we weren''t saving anything that''s worth protecting, and so on. I''d like to have a better

Why is false.blank? => true ?
When using a boolean attribute, often you want to insure that it has a value that is either false or true, but not null. One would think that "validates_presence_of :boolean_attribute" would work for such a purpose, but it does not, because false.blank? => true. I''m guessing this is the expected behavior, but I''m wondering about the rationale. blank? would imply
