Re: CRUD pattern for has_many relationships (forms containin
Hi Christos,
I''ve seen you message in the mailing list archive and I''m trying to
achieve the same behaviour.
Did you progress in your knowledge of the problem this you last
posted? It seems the mailing list hasn''t been that helpful to you.
Maybe we can work out a solution by us two.
Cheers,

has_many through , or habtm , using form

basically i want to fix one product(e.g hp dv7....) to some categories
(notebook,17"notebooks...)
i made a table named categorization(incuding category_id,product_id
fields) then in models i write these codes below
class Product < ActiveRecord::Base

integer array columns
Postgres database.
I have a categories table, with two columns id, and name.
I have a recipes table, with a category_ids column.
I want each recipe to belong to one or more category.
in recipe_controller.rb I have this:
def create
@recipe = Recipe.new( @params[''recipe''] )
@recipe.category_ids = @params[''recipe''][''category_ids''].map{

How do YOU read/update HABTM?
In my mind, it should work like this:
<%= select ''item'',
''category_ids'',
Category.find(:all).collect {|c| [c.name, c.id] },
{},
{:multiple=>true, :size=>20} %>
Then Rails should automatically populate and update HABTM on that. As it
is now, the above won''t work (I created a getter in item''s model that
returns an array of

instance variable problem
I''m having some trouble with an instance variable being read as nil in
my app. I have an image uploading, that can be added to categories.
The page loads up initially fine, and if I upload an image without
errors everything works fine. I''m working on the validation, but with
the code I have if their are validation errors it renders ''new'' again,

Inheritance in Rails - I need some help
I''ve got a model, "category" and another model "subcategory." Each
subcategory belongs_to a category, and a category has_many
subcategories.
What I need to do is set it up so that I can search Category and
Subcategory with one .find call. So:
Category.find(:all, <etc)
will find categories and subcategories.
Now, I believe this can be done by making

Shouldn''t CRUD be CRUDS?
With most models, almost always I find myself writing Search/Find
actions. When I view a Listing of a model, I want to look at another
record or set of records. How nice it would be if I can do a
query-by-example while viewing a Listing, or during Show/Edit/Create.
Would be nice if Search becomes another act in the scaffolding magic.
This wish has been expressed here before. Since then, has

spec''ing metaprograming & rails CRUD
For edge rails there is a Crud generator. There is also a CRUD
controller that is out there from which you can inherit your other
controllers (see http://geekonomics.blogspot.com/2006/07/crud-and-
shared-controllers.html)
This got me thinking about Crud controllers in general. As far as I
know, the generator can''t produce crud classes which are nested

Use Non CRUD with Simply RESTful
Hey guys,
I''m trying out the new RESTful bits in Edge Rails, and am having a bit
of trouble wrapping my brain around certain things. For instance, say I
have a page that is separated into sections with tabs at the top. I want
to replace divs on the page with RJS.
Now typically before I''d have a method on the controller that rendered
an RJS template to accomplish this.

How do CRUD and REST work for a wizard-style application?
I''m rewriting an application with the intention to use the elegant
CRUD and REST design principles as outlined by DHH in his RailsConf
Keynote[1].
The question is: how do you use those principles for an application
that is of a sequential nature?
The application works much like an MS Windows wizard: user begins at
screen foo. After doing (or not) some stuff in screen foo, he is taken

Testing CRUD/Rest Controllers
I have a few simple controllers doing plain, simple crud in a standard way.
now it''s not very DRY to write a funtcional test for each controller, since
they are all doing the same (apart from a few variable names, but that could
be easily inflected or so).
is there a way to do this?
e.g. does inheritance work with tests, so i define a base test first,
inherit my other tests and add a few

Model CRUD via web services
Hello,
I was wondering if there was any automated (may be scaffolding) way of
exposing Model CRUD via web services.
I found this ticket for django, but nothing for Rails.

Thanks in advance for your opinions and suggestions.

Providing limited CRUD access to arbitrary tables through a web interface.
Hi There
I''m starting Rails a project for the first time (used to work with PHP).
I have to provide administrator ("super-user") access to a large number of tables. The access should be available through a web interface (the tables rendered as HTML forms on the browser, probably through HTML tables inside the form). From the CRUD set mostly R(etrieve) and U(pdate) are

Category/subcategory CRUD

I''m starting on ruby on rails, so I have many doubts about it!
I''m trying to create a system that uses categories/subcategories.
I created a scaffold for a table that has the following fields:
- id int(11)
