Is there a way for me to do: OrderItem.find(:all, :include => [:user, :product => [:supplier]] So I don''t have a supplier_id on my order_item, but have it on my product, which is part of order_item. Joerg -- Posted via http://www.ruby-forum.com/.

Hi, I need to download an image, and I''ve mucked about with Net::HTTP resp = Net::HTTP.get_response(''www.mydomain.com'', ''/test.jpg'') f = File.new("test.jpg","w") f.write(response.body) And various other combinations using HTTP.get etc. Anyway, I get an image, but it looks very psychedelic. This is obviously not the correct way.

I have orders, order_items, and products. I want to collate several orders so that I can get a SUM of quantities ordered for each product etc. Can I say something like (the below gives an error on :sum, and ignores :group) OrderItem.find(:all, :sum => ''quantity'', :group => ''product_id'', :include => [:order, :product]) I want to get back a

Hi, I''ve developed a standalone Rails app - using tar2rubyscript and rubyscript2exe. The users aren''t going to understand that the''ll need to open the browser and go to 127.0.0.1:3000 to view the app, after running the exe. I am wondering whether other people have tackled this problem in the past, and how they went about solving it. One way would be to write a

I''m trying to figure out an elegant way to do this: I have the following three tables: people, employer, employees And consequently the following three models: class Person < ActiveRecord::Base end class Employer < ActiveRecord::Base has_many :employees end class Employee < ActiveRecord::Base belongs_to :person belongs_to :employer end I want to be able to say:

I have a loop that I iterate through in my view. <% coll.each do |itm| puts(itm.value) end %> How do I render the itm.value without using a <%= %> tag? Should puts not work? Joerg P.S. There is a good enough reason for me wanting to do this :-) -- Posted via http://www.ruby-forum.com/.

Is there a way to specify not not use schema.rb but instead using a native sql file to clone structure to the test db? Schema.rb doesn''t really work that well for mediumblobs ... Thanks. -- Posted via http://www.ruby-forum.com/.

I''m playing around with the Practical Rails Projects code, and was attempting to make a change for graphing data differently using groupings. Basically the code went from: total_weight = @exercise.activities.collect {|e| e.repetitions * e.resistance} workout_dates = @exercise.activities.collect {|e| e.workout.date.to_s} To: total_weight =

Hi folks, I am running an offline Rails app that periodically connects to the Internet to download the latest catalogue, and upload any new orders. I am about to implement the synching bit - and was thinking whether there is any other solution other than writing webservices and code to do a manual sync of the data, or whether there is a more nifty and robust way using say replication?

Hi I have my routes set up like this: map.resource :contact, :path_prefix => "/employers/:employer_id" so now when I view all contacts for an employer I go to: /employers/1/contacts That works. On that page, there''s a problem with the routes: new_contact_url translates to: /employers/1/contacts/new ... so that works. But, contact_url(@contact) gives me

Hi, I have a webservice. And I want to pass in, a model. So, for example: api_method :save_person, :expects => [Person] When I do this I get an error saying that I cannot have ActiveRecord objects as parameters. Fine. I can have AWS Structs as parameters. I don''t want to start ''maintaining'' a struct everytime I change the table structure od Persons. So, is

Hi, I have method I want to call ... it can receive * number of parameters.

I am new to using S4 methods and have run into this problem (on Windows XP using R 2.4.1): I am writing a package in which I use the graph package. I define my own classes of graphs as: setOldClass("graphsh") setOldClass("ugsh") setIs("ugsh", "graphsh") (I know that I "should have" used setClass instead - and I will eventually - but right now

Hi, I''m running the edge Typo and the latest acts_as_ferret plugin and ferret gems (as of 11 April). In my Content model I put acts_as_ferret :fields => [:title, :body] In the console, I call Content.rebuild_index to index all of my existing content. All the directories get created etc, but I get the following error back: Loading development environment. >>

Could someone please explain why this works: current_user.accounts.sum(:balance) But not this: current_user.accounts.find_all_by_active(true).sum(:balance) For the latter Rails tells me sum is an undefined method. It seems like I lose the ActiveRecord methods when I call ''find''? This (simpler) does not work either: current_user.accounts.find_all.sum(:balance) Thanks! --

I am using acts_as_taggable in my application and on the tagging side of things, no problem at all. Running edge Rails and PostgreSQL 8.1. I am then trying to find all my AR objects with a certain tag. The tag is: lasvegas and I know that there are at least 3 records with that tag. So, I''m doing this: @lists = List.find_tagged_with :any => @search_string, :separator =>

Ruby knows cweek, but MySQL has no knowledge of this value. How do I run a find on class Day, (Day.find :all ... ) with condition [date.cweek = ?, week]? This is not a sql search but a Ruby
