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:
@order_pages = Paginator.new(self,

Pagination links with separator
Hi,
I have @result_pages and @results obtained from paginate in an action. I
want to show the pages as
1 | 2 | 3 | 4 >
The fifth page will show:
< 5 | 6 | 7 | 8 >
and so on.
How exactly do I render the paginator to give this effect? I guess I
will have to use pagination_links_each. But being new to Rails, I need
help.
Thanks,
Yash

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

custom find methods and pagination
i''ve got several methods in my models i use to find based on certain
criteria...i''ve done this so the controller code is less cluttered, plus the
DRY factor.
example:
class Foo < ActiveRecord::Base
def find_by_something(something)
find :all, :joins => ..., :conditions => ...
end
def find_by_something_else(something_else)
find :all, :joins => ...,

Paginating a .find
how exactly would I apply paginate to a .find I have:
@posts = Post.find(:all,
:conditions => [ ''(title) OR (body) LIKE ?'', ''%''
+ params[:query] + ''%''],
:order => ''end_date'')
How would I go about paginating the uoputed list? Something like 10 on a
page.

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

Custom pagination
I am trying to paginate objects from a has_many/:through relationship
using Paginator.
current_user.things returns the objects that I''d like to paginate. For
testing, I tried to make it 1 item per page. I initialise the paginator
as follows:
@thing_pages = Paginator.new(self, current_user.things.count, 1,
@params[''page''])

Newbie: using find like a sql join query
I have a working Rails app with several related tables, but can''t find
an answer to this question in the Dave Thomas Rails book. Imagine for
example:
table departments with columns: id, department_name
table employees with columns: id, department_id, employee_name
and of course the employees table has a constraint foreign key
(department_id) references departments(id)

Reverse engineering pagination and more
Hey all,
I''m building a photo album site (for fun) and have a few questions.
1) This site will have a browse section, where you can view the photos by
thumbnail. I want to let the user change how many thumbs they can see per
page. I''ll have a couple links at the bottom of the page letting them do
that. The problem is, if they are in the middle of browsing and decide to

How to make a drop-down automatically submit an AJAX form
Hi,
I know that to make a dropdown box automatically submit when you change
the value, you do this:
<select ..... onchange="this.form.submit();">
BUT i''ve got an ajax form, and if i do the above trick, it simply
reloads the ajax partial into the whole screen, rather than into the div
where it is meant to go.
I''ve already got it all working so that if you click

two layers of has_many
Hi,
There are many companies. Each company has many departments. Each
department has many employees. The following find_by_sql method seems
awful. What is the best way to get all the employees of a company?
class Company < ActiveRecord::Base
has_many :departments
def employees
Employee.find_by_sql("SELECT employees.*

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

Count_by_content ??
Is there a count_by_content alternative to the find_by_content action?
This is because I''m wanting to do the following in my pagination method:
def list
# step 1: set the variables you''ll need
page = (params[:page] ||= 1).to_i
items_per_page = 20
offset = (page - 1) * items_per_page
# step 2: instead of performing a find, just get a count

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:

:conditions => [''e_date >= ? AND
e_date <= ?'', ''2006-07-12'', ''2006-08-12''],
