Hi Jeremy, thanks for taking the time to reply.
I have checked the Ubuntu box and it seems that it is using the non-ruby driver,
but it reports its version as 4.0.24. This may be the cause of my problems.
I have libmysqlclient version 12, 14 and 15 installed and it looks like rails is
using an older one, can I safely remove the older libs (I do not need mysql
clients other than for rails access) or can I specify which to use in the
environment somewhere. I''m just concerned that if Rails is using the
older client and I remove it, it may stop working.
As to the patch for using stored procedures from Rails, I''ll tidy up
the change and submit as you suggest.
Thanks and regards,
paulie

Yeah. Technically this is a feature in Ruby. :) Allowing you to
overwrite everything for if you need something different for this one
thing. Problem is that you just have to remember a whole lot of
things.

I am new to Rails and am running into a problem with pagination.
Consider model classes Employee and Department:
class Employee < ActiveRecord::Base
belongs_to :department
end
class Department < ActiveRecord::Base
has_many :employees
end
In my controller, I need to get a list of employees working in a given
department, and I need to paginate this list. Any pointers on how to
acheive this?
def list_employees
department_name = "My Department"
@employees = # ... ??
@employee_pages = # ...??
end
Thanks,
Binil

I agree, that looks likely. Can someone tell me how to add data to the
post body, or point me in the direction of the approproate docs ?
thanks.

Content-Type: text/plain; charset=US-ASCII; delsp=yes; format=flowed
(I posted this yesterday but within 20 minutes my thread was hijacked
so I''m not sure anyone really saw this.)
I''ve been working my way through the Agile book and just completed
the depot sample application. I learned quite a bit along the way.
On page 171 we are led through the creation of a test (that fails)
for new code. The new code (a search function) is left as an exercise
for the reader. Well, I think I solved it but I''m not sure I did it
the "Rails way" (even though it passes the test).
After much experimentation, here''s what I did:
1. Edit the depot/app/controller/search_controller.rb file:
class SearchController < ApplicationController
def search
@query = String.new(params[:query])
@products = Product.find(:all,
:conditions => "title like
''%#{@query}
%'' OR
description like
''%#{@query}%''")
flash[:notice] = "Found #{@products.size} product(s)."
end
end
2. cp depot/app/views/layout/store.rhtml depot/app/views/layout/
search.rhtml
3. cp depot/app/views/store/index.rhtml depot/app/views/search/
search.rhtml
4. Edit depot/app/views/search/search.rhtml
Add in another set of <div> tags around it so we have <div
class="results"> as the outermost one. It now looks like:
<div class="results">
<% @products.each do |product| %>
<div class="catalogentry">
<img src="<%= product.image_url %>"/>
<h3><%= h product.title %></h3>
<%= product.description %>
<span class="catalogprice"><%=
fmt_dollars(product.price) %></
span>
<%= link_to ''Add to Cart'',
{:action => ''add_to_cart'', :id =>
product },
:class => ''addtocart'' %><br/>
</div>
<div class="separator"> </div>
<% end %>
</div>
<%= link_to "Show my cart", :action => "display_cart"
%>
5. Change the test so it does "assert_template
''search/search''"
instead of "assert_template ''search/results''".
6. There is no step six.
Was there a better or easier way of accomplishing this task?
Also, why did the book want to test "assert_template ''search/
results''"? That seems like an error to me. The default view for a
controller''s method (action) has the same name as the action, right?
Unless you do a "redirect_to :action =>
''results''" in which case the
"assert_response :success" would now fail because we are redirecting
to a page with a different name. This really confused me and caused
me to flail around much longer than necessary to solve this problem.
Or is the test correct and I can have an action named "search"
rendered by a view named "results"?
