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

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 => ...,

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 item_count =

Say the user first enters "ruby" for search and gets 1000 results. Then he can search "rails" just in the 1000 results just returned. The common scenario is some kind of advanced search. User can incrementally add criteria and the program will narrow the results step by step. I know that at least I can use all the criteria as a whole to do the searching, but this is a waste

I was looking at my controller code and the edit/create/update/new for each are practically identical. So first I DRY''d the four methods in each controller to just one and then I decided to write a single macro for all my controllers. This is the macro: def self.edit_action_for(model, options = {}) model_class = Object.const_get(model) define_method(:edit) do

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

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''m having some strange sorting stuff goign on. Here''s my search method: sort_fields = [] sort_fields << Ferret::Search::SortField.new("name", :reverse => :false) @results = Listing.find_by_contents @search_criteria, :limit => :all, :sort => sort_fields page = (params[:page] ||= 1).to_i items_per_page = 9 offset = (page - 1) *

This introduces support to run P2V without X server. Runtime parameters are specified via kernel command line making it hopefully suitable for automated migration with a little help of PXE boot. Patchset is not squashed and represents dev. history.

I have a an STI table which acts_as_tree, that has a large number of classes/types. My common fields are: id parent_id name description with 4 more text fields, I could cover most of my classes if I could redefine the name of the field like this. text1 AS address1 text2 AS address2 text3 AS zipcode For one class and text 1 AS model_number text2 AS vendor Is there a construct that will allow

Hi, I''m trying to write a macro which defines methods. One of these should have a parameter, but I can''t get that to work. Something like: define_method("printstuff") do puts "blabla" end works fine. But, how do I use define_method to create something like: def printstuff(the_stuff) puts the_stuff end Thanks in advance.

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,

Hi All, I am new to Ruby and ROR I were trying to create small DSL for conditional validations valid_with_cond :bypass_validation do if self.addresses > 3 errors[:base] << "Can not have more than 3 addresses". end end By this I wanted to create array of method and call them all in custom validation method. this above code I wanted to do attr_accessor

Hi all, So far as I know, while using acts_as_ferret, we should add the following declaration in the ActiveRecord model which is going to be indexed: acts_as_ferret({:fields => @@ferrect_fields}) in which @@ferrect_fields is a hash containing all the field to be indexed. This is pretty much for some simple situations. But I got a more complex situation that I want to define the fields to be

Hello, I''m writting some helper methods to write forms, so I have this working code: class TableFormBuilder < ActionView::Helpers::FormBuilder ["file_field", "password_field", "text_field"].each do |name| define_method(name) do |label, *args| @template.content_tag(:tr, @template.content_tag(:td, @template.content_tag(:label,

i''ve figured out how to use the next and previous links with the paginator class but now i''m trying to figure out how to display all the page numbers in between. looking through the rails api, i found paginator.each() but i''m not sure how to use it, or if that''s even what i am looking for. also, is there a way to limit the amount of pages like some sites

Hi guys, got this problem with creating such a thing... hope anyone could help.. the problem: ok, now i have this mock object that would simulate a external rpc call. eg require ''models/xmlrpc_agent'' class XmlrpcAgent def create(params) 200 end end but the value of the value returned is fixed. which is quite hard for me to test the controller when different

Hi, I''ve practically finished a patch for removing the limitation of CheckListBox (http://rubyforge.org/pipermail/wxruby-development/2007-October/000973.html) but I just discovered a new bug related with this control !! I need to redefine the delete method to take into account the deletion of the associated data. The problem is that if I just redefine this method and simply call super,

Hi folks, I''m in the process of converting a Test::Unit functional test to RSpec, but I''ve run into a slight problem.
