similar to: paginate a collection

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 Alain. -- Posted via

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

Hello, I have 2 tables table colors : +----------------------+ | id | user_id | name | +----------------------+ | 1 | 1 | test1 | | 2 | 2 | test2 | | 3 | 3 | test3 | +----------------------+ table users : +----------------------+ | id | enabled | name | +----------------------+ | 1 | 1 | bob | | 2 | 1

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 =>

I have the following: def index begin @restaurant_pages, @restaurants = paginate :restaurants, :order => (params[ :sort ] || "name"), :per_page => 2 @cuisines = Cuisine.find_all rescue redirect_to :action => :index end end # sort by cuisine def

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

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,

I have searched for days for an example that demonstrates what i would like to do, and this morning i thought i''d worked it out, but no....here''s what i have: Controller ========== class ProfilesController < ApplicationController def friends current_user.profile.friends end def list_friends @profile_pages, @profiles = paginate( friends, :per_page => 10) end end

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 => ...,

The built-in Rails pagination is fairly limited...you pass in the model name, and optionally some conditions, and it generates a paginated query for you. This gets to be very bad if you''ve got any custom queries. class Company < ActiveRecord::Base def complete_videos Video.find :all, :conditions => "company_id=#{id} AND status=''complete''", :order

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 I poked around through the Wiki

Im using this paginate function to paginate complex sql queries http://www.bigbold.com/snippets/posts/show/389, all seems to work fine but theres one thing, when i hit the next link it show nothing, i mean it only shows the first page, here is the code im using: #application.rb----------------- def paginate_collection(collection, options = {}) default_options = {:per_page => 10, :page

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.

Hi, I''m trying to figure out how to use paginate when one of the conditions depends on the association between one model and another. For example: I have a model Authors which has_many Posts. I would like to find all the authors and order them by the number of posts that they have published and then paginate those results. What if I wanted to base the paginate condition on all the

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'']) I don''t know how to obtain

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

I''m using will_paginate in a Post class method; [code]def self.list(page) paginate :per_page => 10, :page => page, :include => :user end[/code] I can happily use the method on my posts controller index action; [code] class PostsController < ApplicationController def index @posts = Post.list(params[:page]) respond_to do |format|

Hi there everyone, I''ve recently moved to RoR and am still struggling with the basics of what used to be second nature in php, so on with my question: I have a database with products, and I need to create a search form that paginates the results. What I have so far in my controller is: def list # If the values are nil, then set them, otherwise wrap them in % # Also,

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?

I have a controller and list page for region object. My list page has a ''name'' text input that can be used to limit the list. It works except that the paginate gets the full set of regions unqualified by my search term. I believe this full list is contained in :regions symbol which I dont seem to be allowed to modify or replace (yes I am a ruby and rails newb). How can I
