Editing my question
for conciseness and to update what I've done:
How do I model having multiple Addresses
for a Company and assign a single Address to a Contact, and be able to assign them when creating or editing a Contact?
Here is my model
for Contacts:
class Contact < ActiveRecord::Base
attr_accessible :first_name, :last_name, :title, :phone, :fax, :email, :company,
:date_entered, :campaign_id, :company_name, :address_id, :address_attributes
belongs_to :company
belongs_to :address
accepts_nested_attributes_for :address
end
Here is my model
for Address:
class Address < ActiveRecord::Base
attr_accessible :street1, :street2, :city, :state, :zip
has_many :contacts
end
I would like, when creating an new contact, access all the Addresses that belong to the other Contacts that belong to the Company. So here is how I represent Company:
class Company < ActiveRecord::Base
attr_accessible :name, :phone, :addresses
has_many :contacts
has_many :addresses, :through => :contacts
end
Here is how I am trying to create a field in the View
for _form
for Contact so that, when someone creates a new Contact, they pass the address to the Address model and associate that address to the Contact:
<% f.fields_for :address, @contact.address do |builder| %>
<p>
<%=
builder.label :street1, "Street 1" %> </br>
<%=
builder.text_field :street1 %>
<p>
<% end %>
When I try to Edit, the field
for Street 1 is blank. And I don't know how to display the value from show.html.erb.
At the bottom is my error console -- can't seem to create values in the address table:
My Contacts controller is as follows:
def new
@contact = Contact.new
@contact.address.build # I GET AN ERROR HERE: says NIL CLASS
@contact.date_entered = Date.today
@campaigns = Campaign.find(:all, :order => "name")
if params[:campaign_id].blank?
else
@campaign = Campaign.find(params[:campaign_id])
@contact.campaign_id = @campaign.id
end
if params[:company_id].blank?
else
@company = Company.find(params[:company_id])
@contact.company_name = @company.name
end
end
def create
@contact = Contact.new(params[:contact])
if @contact.save
flash[:notice] = "Successfully created contact."
redirect_to @contact
else
render :action => 'new'
end
end
def edit
@contact = Contact.find(params[:id])
@campaigns = Campaign.find(:all, :order => "name")
end
Here is a snippet of my error console:
I am POSTING the attribute, but it is not CREATING in the Address table....
