Using now() to determine what should be displayed
I''m trying to create a paginated list that will take note of the
"end_date" field in my table. This is what I have:
@post_pages, @posts = paginate(:posts, :per_page => 10, :order_by =>
''end_date'')
in the controller. And for the view:
<h1>Posts ending soon</h1>

will_paginate question
Hi-
Is it possible to use search parameters with will_paginate?
For example, something like this:
@var = Model.paginate :per_page => 20, :page => params[:page],
:order => ''my_date DESC'', :conditions
=>["my_date >= ? AND my_date <=?",@start,@end]
I am getting some errors with this, but will this generally work?

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.

Using AND in :conditions queries
I have what amounts to a simple search engine running through a table
using input from a form. Everything works fine when looking for "title"
or "body" But, when I want to couple that with an AND statement the
search still works fine, but it seems to disregard the AND statements.
Code below:
In the view:
<%= start_form_tag :action=> "show_search" %>

Sorting ferret results by column
I have the acts_as_ferret plugin installed. Everything searches great,
but I would like to limit the results (i.e. by ''end_date'') and sort them
(by ''end_date''). ''end_date'' is a valid column in my "posts" table.
Here''s the code I have already:
@posts = Post.find_by_contents(params[:query])
params[:query] comes from a form. I

Paginate with Rails 2.0.2 question
Hi,
So I''m using @post_pages, @posts = paginate :posts, :per_page => 10
to paginate.
But I have rails 2.0.2 on my VPS. Now this version of paginate throws
an error. What happened to classic pagination and what is done now?
Thanks,

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.

I am working on a dataframe cam and it involves comparison within the
