Do these addresses have any difference besides being primary or secondary? Are there extra fields in one that are not in the other? Or is primary maybe a boolean on the address object?
Walter
Create two associations with conditions on the parent table with conditions that point to each “type” of address.
For instance:
has_many :addresses
has_one :primary_address,
->() do
where( :type => :primary )
end,
:class_name => Address
This will make primary address accessible through addresses but also make it its own association ( so you can just pass that association to the form ).
Be aware that changes to one association will not be reflected in the other. So if you change “primary_address”, before you reload, the object in addresses which corresponds to your primary address will not have the changes you made to primary address. After you save/reload, they will.
*changes to one association will not be reflected in the other until reload.
Is @lenders a single parent or an array? Presumable an array since it is plural. In which case you can't just test state_id_string. Possibly you need something like @lenders.where(some condition on state_id_string), assuming that state_id_string is a database field. Alternatively perhaps you want to use @lenders.each to select and test them one at a time.

Okay... I am really trying to be super vigilant to best Ruby/Ruby on Rails practices here... the whole n + 1 matter particularly
I have a parent table called Advertiser:
This is how it looks on the database:
CREATE TABLE advertisers ( advertiser_id varchar(40) NOT NULL,
If you are committed to the rails conventions then that should just be id, not advertiser_id. advertiser_id should be used in another table that belongs_to advertiser.
title varchar(50) NOT NULL, category_id int(3) NOT NULL DEFAULT '99', ... class Advertiser < ActiveRecord::Base
require 'uri'
self.primary_key = 'advertiser_id' attr_accessor :item_image_upload has_one :item_image has_one :category
You have has_one category, but also a category_id in the table either it should be belongs_to category or the field should not be there.
... CREATE TABLE categories ( category_id int(3) NOT NULL DEFAULT '99', category_type varchar(50) NOT NULL, KEY category_type_index (category_type) ) ENGINE=MyISAM DEFAULT CHARSET=utf8;
Categories exists as category.rb, and this is the model:
class Category < ActiveRecord::Base
self.primary_key = 'category_id'
belongs_to :advertiser belongs_to :borrower belongs_to :lender
You need _id fields for each of the above.
... I am really committed to using best practices. What an I doing wrong? I am not clear as to model requirement regarding look up values that are user nonchangeable... The whole notion, for example, has_one with regard to a look up is not clear to me.
Have you worked right through a good tutorial such as railstutorial.org (which is free to use online), including all the exercises? That should help to make the basics of rails more clear.

Who are you saying thank you to? The quoted message did not seem to include any help. It might be better to put your reply after the relevant section of the message you are replying to (as I have done here), then it is easier to follow what you are saying.

I am thanking you, Colin
That is ok, glad to be of help. However I note you ignored my other suggestion, or at least did not act on it. I was:

Nobody has suggested that you have not thanked folks. What I was commenting on was the fact that you have been replying at the top of the previous message rather than replying to it with comments inserted in the previous message at appropriate points, which I think is more appropriate for technical mailing lists and is generally the convention on this list. I see that you are using gmail, perhaps you do not know that gmail hides the previous message by default, but if you click on the three little dots that appear at the bottom of the text window when you click Reply then it will show the previous message so you can insert your reply at the appropriate point.
Cheers

This is an old post, but I hope I can help with the seeming confusion : ) Liz, what Colin was referring to is this Posting style - Wikipedia. Colin prefers inline-or-bottom-posting-with-trimmed-quotes over top-posting-with-full-quotes (wc you prefer). In a way, Colin is telling you to help him help you better.
hope that helps. kind regards --botp
