Rails - Apr 2007 - Moving multiple attributes to a new table - please help!

Okay I have a "list" view that contains a package inventory stored in
a
table called addpackages.   Attributes include fname, lname,
packagetype, email, phone, etc.


Here''s what I''ve done already:
1. When you click the last name of a person in the list view simulating
they are picking the package up, you go to my custom edit view.
 <td><%= link_to addpackage.lname, :action => "edit", :id
=>
addpackage.id %></td>


2. Here is my custom edit view:
<form action="../update/<%= @addpackage.id %>"
method="POST"">
 <input id="addpackage_id" name="addpackage[id]"
size="30"
 type="hidden" value="<%= @addpackage.id %>" />

 <p><b>User must enter initials to claim
package:</b><br>

  <input id="addpackage_signature"
name="addpackage[signature]" size="5"
 type="text" value="<%= @addpackage_signature %>"
/>
 </p>

 <input type="submit" value="Sign for package" />
 </form>


3. This all works fine for getting the signature in the addpackages
table.   What I would like to do at this point is copy a few
attributes(lname, fname, signature, phone) to a table called receipts?
I''ve already created a relationship between addpackages and receipts, I
just need help with coding behind this operation.  I figure I would
perform this operation in the addpackage controller under "def edit"
but
I really need a kick start to coding this or someone to tell me this is
the correct way to do it.


Help will be greatly greatly appreciated!!!

-Tony

It would really help if you could give us the relationships between the 
models.  From my understanding, you are trying to copy the fields from 
one table to another right?  In that case, you can look up the package 
record in the receipt model and copy the attributes to the current 
records.

I think we are on the same page, but here''s a visual representation
just
in case.

1: The ID# is clicked when a user comes to the mailroom to get their 
package
http://aycu34.webshots.com/image/15313/2002794410554314194_rs.jpg

2: The app will prompt for the users initials
http://aycu24.webshots.com/image/15343/2002700669700389807_rs.jpg

3: Upon clicking the Sign for package, the initials/date are logged, and 
what I want to happen is to copy all all fields needed to fill this 
following Receipts table, and at the same time delete the selected 
record from Inventory, as the package has been picked up and it is no 
longer in the mailroom.
http://aycu01.webshots.com/image/13400/2002736555382712550_rs.jpg

Here are my relations at the moment:

class Addpackage < ActiveRecord::Base
  belongs_to :category
  has_and_belongs_to_many :rosters
  has_many :receipts
  end

class Receipt < ActiveRecord::Base
  has_and_belongs_to_many :addpackages
end



I''ve been trying to do this operation from both the addpackage 
controller and receipt controller but have failed.   I''m still a newbie
to rails so it might just be my syntax or incomplete knowledge.   You 
said above I could perform all these operations from receipt.db model? 
I have never put anything but relations in those.

Anyway I have exhausted myself trying to get this to work.    I''ll keep
hacking at it, but im not getting much of anywhere.

2 hours later I still can''t figure out how to make this work.   Are my 
relations correct?    If someone could throw me a couple lines of code 
or even point me in the right direction it would really make my day!!

The very words ''copy attributes'' should send shivers down your
spine
as a Rails developer.  It really sounds like what you''ve got is a
third object that is related to packages and receipts -- user/person/
addressee or something of that sort.  I''d think something like:

class User < ActiveRecord::Base
  has_many :packages
  has_many :receipts
  ...
end
(the class above carries the data you want to copy -- name fields,
etc)

class AddPackage < ActiveRecord::Base
  belongs_to :user
  ..
end

class Receipt < ActiveRecord::Base
  belongs_to :user
  ...
end

Your User class could have a method that "transfers" the item from
"Inventory" (I don''t see any class relationship for that) to
Receipts:

def signed_for(add_package)
  self.receipts.create(:add_package_id =>
add_package.id, :picked_up_at => Time.now)
  # some code to remove add_package from inventory
end

Note: It''s MUCH better to put this type of business logic in the model
and not the controller.
