form_for() and name
how can i give name attributes for form_for(), so it will give an output
like <form name="f">. it is because that i need to access the form name
for javascript manipulation.
as far as i know, name can only used in form_tag(), but i currently have
more than 50 forms that built using form_for(). the structure is like
this:

many-to-one relationship, do I need a second table?
Ok, to keep things short. Im wondering if I need a secondary
relationship table to handle my many-to-one relationships. Here is an
example of what I''ve written down. For instance say I want to find all
of the people in a given location.
class Location < AR:Base
has_many :people
end
class Person < AR:Base
belongs_to :location
end
My SQL tables look like:

Dynamically add radio buttons to forms?
Good afternoon all
I''m trying to implement a form that dynamically inserts radio buttons
into a form. The user selects options from a drop-down menu. I use
observe_field to watch for a change and call back to render the
appropriate partial tha contains the radio options. All works nicely
but I''m tripped up on one thing:

Table Relationships Problems.
I have the following tables setup:
locations
:id
:name
systemmessages
:id
:name
systemmessage_validtimes
:id
:name
:systemmessage_id
:location_id
:start
:end
The systemmessage_validtimes has a ''has_many'' relationship with
systemmessages, meaning that there could be many valid times for each
system message.
@systemMessage = Systemmessage.find(1)

Accessing belongs_to objects from a form_for context
In a form_for context, is there a way to access objects that are related
to the primary object with a belongs_to? I think an example will serve
best:
class User < ActiveRecord::Base
belongs_to :person
attr_accessor :username
end
class Person < ActiveRecord::Base
has_one :user
attr_accessor :first_name
end
<% form_for :user do |form| %>

Validation dependent on unsaved parent
I''m having trouble with a validation that depends on an attribute of a
belongs_to parent. If the child is added to an unsaved parent
(parent.children << new child), the has_many collection
parent.children includes the unsaved child. However the belongs_to
attribute child.parent appears to be nil until the parent has been
saved. Without access to the parent attributes, the validation

Rewriting FormBuilder

I want to extend formbuilder to make it output a lable (I know about

Getting started w/ Rails 4
Hi. I''m trying to run Getting started tutorial under Rails 4.0.0.beta1
although it assumes it runs on Rails 3. I was able to get rid of all
errors by wrapping post_params here and there, and installing
protected_attributes Gem for attr_accessible to make sense. Post/
comment CRUD works just fine, but I don''t seem to be able to add Tags
