similar to: arrays in model objects

Given a field in database defined as "discount_rate numeric(3,1)" I found it not very usable for presenting it directly. For example, if there''s a value 5.00 it will render in <%= text_field ''model'', ''discount_rate %> as "0.5E1" which is not very friendly to user. All I do is that I write kind of proxy accessors (prefixing with

I''m getting confused. If I have a view (.rhtml), I can use a field helper like: <%= text_field :mymodel, :attribute %> This uses the value from @mymodel.attribute Now, if I am rendering a template normally (i.e. not partial), I would expect @mymodel to be a model object defined as an instance variable in the controller. However, if I am rendering a partial template, I

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| %> <%= form.text_field

Hi, I''m trying to implement password confirmation, based on the Agile example, but just can''t make any progress. User DB has these fields: ========================= t.column :name, :string, :limit => 40 t.column :hashed_password, :string t.column :salt, :string User model has: =============== attr_accessor :password_confirmation

This might be a problem with postgresql, but I''m not sure. In a migration I have renamed a table so I wanted to rename a sequencer as well. It looks like: execute "ALTER TABLE global_vacations_id_seq RENAME TO vacations_id_seq;" execute "ALTER TABLE vacations ALTER COLUMN id SET DEFAULT nextval(''vacations_id_seq''::regclass);" But the process of

I have the following models: class Order < ActiveRecord::Base belongs_to :billing_address belongs_to :shipping_address accepts_nested_attributes_for :billing_address accepts_nested_attributes_for :shipping_address, :reject_if => proc { |attributes| attributes[''has_shipping_address''] != ''1'' } def after_initialize self.build_billing_address

With the help of several heroes here yesterday I beat my way into a working solution to adding comments to one or more models in my application using acts_as_comentable. Great plugin, but my implementation is lame. I need enlightenment. I have users who log in. For several views I want to let them add comments. Enter act_as_commentable which does just this -- it''s polymorphic, so you

Hi, I have some problems with an application where I''m using custom accessors to do currency conversions. In my model, I have a price attribute in the database that stores the value in cents, to avoid future problems with float arithmetic and round. But at the views, I would like to show the price in euros, with decimal for the cents. So I defined a new attribute called price_in_euros,

Hi, I''m trying to do a bulk update on an array with the helper text_field. I''m trying to create an inputfield for every object in the array, but I''m not getting it right... example: class ClassA @arrayB[] end HTML (code with error): <% 0.upto(9) do |index| %> <%= text_field ''ClassA'', ''arrayB[index]'' %> non

When submitting billing information in the past I''ve always used attr_accessor for credit card details as they should not be saved in the database. In addition I always end up storing the card expiration date so that the date form helper works correctly. With Active Model it seems logical to create a CreditCard class to hold this data instead. **1st issue.** It seems there still

Hello, I am trying to do something and I''ve been reading my Agile Web Development with Rails book and doing internet searches for several hours now and I have made no progress. Here''s the issue: I have a table of sales reps that is linked to a table of territories. There are around a thousand territories that are numbered and each sales reps has many territories. I will

I have in my view the following: <% 0.upto(@num_performances) do |idx| -%> <%= text_field ''performance'', ''city'', :index => idx, %> <%= text_field ''performance'', ''venue'', :index => idx, %> <% end -%> and in my controller I have: @performance = [Performance.new("city" =>

Hey, I got a form which looks like this: - form_for(@article, :html => {:multipart => true}, :url => articles_path) do |f| = errors_for(@article) .field = f.label :text %br = f.text_field :text .field = f.label :author_id %br = f.text_field :author_id .actions = f.submit But since I don''t want anyone to type in an author id I changed it

All, I''m having a hell of a time figuring out what is going on here. I''m trying to override one of my getters so that I can format it a certain way in my form. But I can''t seem to get text_field to call the appropriate method on my object. So here''s my getter: public def FAX fax = read_attribute(:FAX) puts fax

I was thinking about having instance variable stored and fetched from session container automatically before calling an action and after the action is finished. Using methodology of accessors it would look like: class MyController < ActionController::Base persistent_attr :person def alfa person = ''John Smith'' # render as usual view alfa.rhtml with anchor

Hello, I have the following: My Controller: def new . . @teammembers.each do |teammember| request = @request_thread.requests.build(:recipient_id => teammember.user_id, :full_name => ''Billy Bob T'') end My View: . . <%= f.fields_for :requests do |builder| %> <div class="field"> <%= builder.label

So here is what the array might look like: (Inside the params hash) "post" => [ {"id"=>28, "title" =>

Hi, (probably) A newbie questions: I have a form where a user can choose an email address, but there are only some choices for the domain, so I wrote a helper where the local part of the email is a text field and the domains is a dropdown list, like: Select Email: [ my_name ] @ <domain.com> ..which I defined as a helper: def email_form(tagname, domain_list)
