I have 2 tables: Products and ProductLines

Products:
id
product_line_id

ProductLines:
id
product_line


Product Model:
Code:
     class Product < ActiveRecord::Base
       belongs_to :product_line
     end
ProductLine Model:
Code:
     class ProductLine < ActiveRecord::Base
       has_one :product
     end
In my listing code, I am trying to show the product line for each product like this:
Code:
     <% for product in @products %>
       <tr><td><%=h product.product_line %></td></tr>
    <% end %>
I am getting this error:
DBI: DatabaseError: Execute
OLE error code:80040E37 in Microsoft OLE DB Provider for SQL Server
Invalid object name 'product_lines'.
HRESULT error code:0x80020009
Exception occurred.: SELECT TOP 1 * FROM product_lines WHERE (product_lines.id = 4)


Note that it thinks my table is named 'product_lines' when it is really named ProductLines. Also note that I am using MS SQL Server, which should be fine, but is noteworthy.
