"Selecting" a calculated row / Using :select in the paginate method
Hi,
I was trying to use the :select parameter to select a calculated row,
but it appears that the parameter is not picked up by the paginate method.
I want to add the following to the select statement:
timediff(now(), created_on) as age
So I tried:
@story_pages, @stories = paginate :stories, {:per_page => 10, :include
=> ''user'', :select =>

Complex SQL in paginate command?
Hi all,
Is there a way to create pagination with a complex SQL, more complex
than the :conditions option will support?
I have two databases, houses and images. Houses has_many images, and
each Image belongs_to house.
I''m creating a search engine for the house records and I''d like to be
able to filter out all the houses without any associated images.
So far I''m

How to pass a collection to paginate?
There must be a better way to write this code:
@project_pages, @projects= paginate :project,
:per_page => 10,
:conditions => ["account_id = ?", account]
?!
If only I could pass the sub-collection
account = ...
@projects = account.project
to paginate, instead of letting it extract it with a find :all + sql
conditions

Pagination - why is it this hard?
Hi everyone,
I''m at the end of my rope on this. I can''t get pagination to work
with anything but a standard find on a model. If I try to do a search
and customize the pagination, I get lots of different variations.
My thought was to have the list action do what it does, but to pass it
a list of search conditions from the search action. So, if search
determines that we need

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:

Executing SQL in rails, and the types of the data returned
Hi,
Every once in while I have to run SQL by hand, in my models mostly. But
I''m wondering if there is a better way of doing it than I do. And, I
have a question concerning types of the fields in the result the query
produces.
First, about the types. In a certain model, to get and return the value
of a boolean function, I have to do:
result =

acts_as_taggable and paginate?
Hi there,
I''ve been trying to paginate over a list of members that all share a tag in
common using the acts_as_taggable plugin. The regular way of paginating over
a collection doesn''t seem to work with acts_as_taggable. Here''s what my
method looks like that takes in a tag name, finds all the members that share
the tag and then displays all the members. Nothing too fancy

complicated finds are eating my sole
I abandoned ruby way for find_by_sql and still can''t get this...
@myplacement = Placement.find_by_sql(
"select * from placement where
:intake_date >= beg_intake_date
and
:intake_date <= end_intake_date")
just a simple date range...it''s killing me - If I knew how to load
placement controller into irb, I could probably try out finds
interactive mode...
Thanks

how do i paginate the results of a query?
I have a controller and list page for region object. My list page has a

It works except that the paginate gets the full set of regions unqualified

Scalable alternative to #find_all
Is there any scalable alternative to iterating all the records of a
certain model? #find_all seems to load everything into memory. With
500.000 records it will be a swap storm.

use join table in paginate
How come I allways immediately run into difficult stuff when I''m trying
some new programming language? Am I blind for the simplicity of
Ruby/Rail, which a see must be there? Anyway, don''t try and answer this
rhetoric question. I have got another one for you, seemingly difficult.
I''m struggling with a n:m relationship (in a database, that is) and its
join table.

Paginate @member.items?
Is there a quick and easy way to paginate something
like @member.items (Member with has_many :items)?
Right now I do in the controller:
@item_pages, @member_items = paginate :item,
:conditions=>["member_id=?", @member.id],
:per_page=>25,
:order=>''datetime desc''
It''d be more DRY if this was possible:
@item_pages, @member_items = paginate
