Include with two references of one model of the same table
Hey guys,
I just came across this oddity, not sure what to make of it yet, but
I think it might be incorrect behavior. When doing a @inst.find(:all,
:include => ["hometeam", "awayteam"] ...) hometeam and awayteam are two
references from a belongs_to that is of the same model and of the same
table. I will get a pgerror stating that "matches", which is

Problem with Pagination
Hi Guys,
I am trying to paginate the results from a search. When I use actual
constants in the search conditions, it works fine:

@k2_result_pages, @k2_results = paginate (:k2_results,
:conditions => [''e_date >= ? AND
e_date <= ?'', ''2006-07-12'', ''2006-08-12''],

Pagination and Parent Conditions
Can I do any "fancy" conditionals when using the Pagination helper?
The problem is that I want to be able to specify a conditional based
on the criteria of a parent object. Here''s an example:
Object A has_many Object B''s
I want to paginate through 100 B''s but I *only* want it to return the
ones who''s A.flag = true

Can pagination work with caching
I am currently caching a page that indexes blog entries. Paginate was
used to break the entries up. Now when you click on next at the bottom
of the page it is only reloading the first page. Im hoping, against
odds, that someone here knows of a way to make paginate and cache play
together.

Pagination help/how to
Hello,
I want to know how can I paginate a set of records. It seems
there is no direct way of doing this, and I am not able to understand the
documentation of paginate, so any pointers on how to do this will be much
appreciated.
To be specific what I want is that the records returned by user.recipes, the
recipes of the particular user be paginated.
My attempt to do this failed because

Pagination of Complex Queries
I''ve created a class method in my model called find_filtered. The intent is
that I take various params that the user has submitted, and let the model
build the query and return the AR collection, which is exactly what happens.
However, now I''d like to paginate the recordset. Everything I''ve been able
to find about pagination presumes that you have no pre-existing AR

another simple question: per_page in pagination
Hi,
Why can''t I use a variable to specify the :per_page attribute when using
the most basic form of pagination? (if I use a hardcode number, it
runs) What did I do? Thx.
My code:

page_size = 20

order_pages, @orders = paginate(:orders, :per_page => page_size)

pagination over custom-sorted collections?
I have a little web app where we need to paginate collections of
items. I''m trying to sort the collection and then pass it, sorted, to
a Paginator, and still be able to paginate through the collection,
across several pages, with the new sort order. The only thing I''m
doing differently from the regular scaffolding approach is this:

Pagination
Hello,

other functionality. For example I need paginate only a little bit

Pagination Question
Hi -
I''ve just started working with Rails, having come from a Cold Fusion
background. I''m curious how best to deal with a huge result set. For
example, I''m building an app that contains users. I''ve used
scaffolding to setup my initial pages for CRUD operations on users.
All that is great. The problem is, I''m going to end up with 1000+
