I''m trying to learn rails as I go along, and having a bit of trouble. There is an undefined method cropping that I don''t know why rails thinks should be there. Firstly, I''m using rails 3, ruby 1.9.2 I have a controller with an index action This part works fine, but i am trying to add a comment form to the page that is rendered by that index action.

Need some advice. I''ve got two modules: artists and paintings. In my home page, I''ve got a 2nd page that says "Browse paintings", which displays ALL paintings of ALL artists. This is being rendered by paintings#index. In another page, I should show all paintings of a specific artist ONLY. Meaning, paintings from ONE artist. I cant use paintings#index for this anymore

I have a dataset, which contains a day column that I would like to retrieve results on. Is there any reason why daily_stats.where(''day = Date(?)'', dte).first returns and empty set, daily_stats.find(:first, :conditions => [''date(day) = ?'', dte]) returns the correct data and daily_stats.where({:created_at => (date.midnight - 1.day)..date.midnight}).first

Hi list, how are ya? So, my current project is just begging for the ability to have parameterized associations in my ActiveRecord classes. Basically I need something that is a cross between named scopes and standard associations (has_many specifically). I''m wondering if such a thing exists or, if not, if anyone else has an elegant, equivalent solution? Example: class Sprocket <

Artist.first.medias returns all medias. Media is an STI. Media can be video or painting. How do I return all paintings of an artist? Only paintings, not videos? In my Artist model, I tried putting: has_many :paintings, :through => :medias In console, I do: Artist.first.paintings.all And I get: ActiveRecord::HasManyThroughSourceAssociationNotFoundError: Could not find the source

Hey all, I get the following error. Now I know it''s related to a curly brace, but it seems that all curly braces are properly in place.

When I have this pattern sign_me(@user, :event => :authentication, :subdomain => subdomain) how can I write it to avoid sending the :subdomain option if subdomain.nil?

Hello all! I have a conundrum that I''m _sure_ someone else has already thought of and solved. How does one best handle the scenario of association object changes and data integrity? For example, if I have a standard ecommerce site that sells Products and people can have Orders and an Order has_many Products... then, what happens if Product #3 is part of Order #2 but at some point, the

This is ALL I have added to my routes.rb map.connect ''admin'', :controller => ''/admin/welcome'' I have found plenty of examples saying this is correct if you have a WelcomeController in the Admin module, which I do :) But now webrick won''t even start ???

I''m trying to figure out how to change the order of a list view and it''s obvious to me that I don''t understand what I get from a simple scaffold to know enough to alter it.

I would like to define some constants that I can use across models and views and I cannot figure out how to do that. Googling hasn''t turned up anything useful and I''m looking at the PickAxe book, and I get the impression that a constant must belong to a class. If I just want a constant like... CompanyPhoneNo = "(602) 999-9999" and be able to use it in any view

Hi there, I wanted to use RedCloth with my RubyOnRails 3 application, but it seems that RoR uses 1.9.2''s Psych by default as the YAML parser if available, and Psych fails to load the LaTeX entities file: ==================================================================== #ruby -v: ruby 1.9.2p136 (2010-12-25 revision 30365) [x86_64-linux] irb(main):001:0> Dir.pwd =>

I''m sure everyone has read and committed the Puppet Best Practice to memory by now (I joke). One of the things I''ve written in there deals with trailing commas, which I adopted from the way I used to do multiline in Perl, but I''ve noticed that most people don''t tend to do that in Puppet. Should I revise this or should we all start using the trailing commas?
