  • Shortcut for rake db:migrate:down for ruby-on-rails

    - by Michaël
    Hi, I want to know if there is a short way to do the migrations down equivalent to rake db:migrate (for the migrations up). Instead of doing : rake db:migrate:up VERSION=1, rake db:migrate:up VERSION=2, ... we can do : rake db:migrate! But for : rake db:migrate:down VERSION=10, rake db:migrate:down VERSION=..., rake db:migrate:down VERSION=1, is there a shortcut? Tank you for your help!

  • Strange ruby behavior when using Hash.new([])

    - by Valentin Vasilyev
    Consider this code: h=Hash.new(0) #new hash pairs will by default have 0 as values h[1]+=1 # {1=>1} h[2]+=2 # {2=>2} that's all fine, but: h=Hash.new([]) #empty array as default value h[1]<<=1 #{1=>[1]} - OK h[2]<<=2 #{1=>[1,2], 2=>[1,2]} # why ?? At this point I expect the hash to be: {1=>[1], 2=>[2]} But something goes wrong. Does anybody know what happens?

  • How to organize a Shoes Ruby app?

    - by luca
    can I have some examples of how you organize your Shoes apps? I mean, simply using a Shoes.app{} block and instance variables is clumsy.. I'd like to achieve a MVC like structure.. I'm used to it (from rails, FLEX frameworks and others..) and would like to recreate something similar..

  • Ruby &&= edge case

    - by Alan O'Donnell
    Bit of an edge case, but any idea why &&= would behave this way? I'm using 1.9.2. obj = Object.new obj.instance_eval {@bar &&= @bar} # => nil, expected obj.instance_variables # => [], so obj has no @bar instance variable obj.instance_eval {@bar = @bar && @bar} # ostensibly the same as @bar &&= @bar obj.instance_variables # => [:@bar] # why would this version initialize @bar? For comparison, ||= initializes the instance variable to nil, as I'd expect: obj = Object.new obj.instance_eval {@foo ||= @foo} obj.instance_variables # => [:@foo], where @foo is set to nil Thanks!

  • Basic Array Iteration in Ruby

    - by michaelmichael
    What's a better way to traverse an array while iterating through another array? For example, if I have two arrays like the following: names = [ "Rover", "Fido", "Lassie", "Calypso"] breeds = [ "Terrier", "Lhasa Apso", "Collie", "Bulldog"] Assuming the arrays correspond with one another - that is, Rover is a Terrier, Fido is a Lhasa Apso, etc. - I'd like to create a dog class, and a new dog object for each item: class Dog attr_reader :name, :breed def initialize(name, breed) @name = name @breed = breed end end I can iterate through names and breeds with the following: index = 0 names.each do |name| dog = Dog.new("#{name}", "#{breeds[index]}") index = index.next end However, I get the feeling that using the index variable is the wrong way to go about it. What would be a better way?

  • Basic Ruby On Rails Linking Help

    - by dweebsonduty
    So I am beginning to work with Rails and I get some of the concepts but am stuck on an important one. Let's say I have customers which has many jobs and jobs which belongs to customers. How would I go about creating a new job for a customer? I can create a link that goes to customers/1/jobs/new and I can grab the customer ID but how do I tell it that I am creating a job for customer 1? I know this is the most basic of things but I just need a push in the right direction. This is my form so far: How do I get :customer_id to populate with the customer_id param? <h1>New job</h1> <% form_for(@job) do |f| %> <%= f.error_messages %> <p> <%= f.label :customer_id %><br /> <%= f.text_field :customer_id %> </p> <p> <%= f.label :manufacturer %><br /> <%= f.text_field :manufacturer %> </p> <p> <%= f.label :serial_number %><br /> <%= f.text_field :serial_number %> </p> <p> <%= f.label :problem %><br /> <%= f.text_area :problem %> </p> <p> <%= f.label :notes %><br /> <%= f.text_area :notes %> </p> <p> <%= f.label :status %><br /> <%= f.text_field :status %> </p> <p> <%= f.label :tech_id %><br /> <%= f.text_field :tech_id %> </p> <p> <%= f.submit 'Create' %> </p> <% end %> <%= link_to 'Back', jobs_path %>

  • Ruby Metaprogramming

    - by VP
    I'm trying to write a DSL that allows me to do Policy.name do author "Foo" reviewed_by "Bar" end The following code can almost process it: class Policy include Singleton def self.method_missing(name,&block) puts name puts "#{yield}" end def self.author(name) puts name end def self.reviewed_by(name) puts name end end Defining my method as class methods (self.method_name) i can access it using the following syntax: Policy.name do Policy.author "Foo" Policy.reviewed_by "Bar" end If i remove the "self" from the method names, and try to use my desired syntax, then i receive an error "Method not Found" in the Main so it could not find my function until the module Kernel. Its ok, i understand the error. But how can i fix it? How can i fix my class to make it work with my desired syntax that?

  • Ruby Methods: how to return an usage string when insufficient arguments are given

    - by Shyam
    Hi, After I have created a serious bunch of classes (with initialize methods), I am loading these into IRb to test each of them. I do so by creating simple instances and calling their methods to learn their behavior. However sometimes I don't remember exactly what order I was supposed to give the arguments when I call the .new method on the class. It requires me to look back at the code. However, I think it should be easy enough to return a usage message, instead of seeing: ArgumentError: wrong number of arguments (0 for 9) So I prefer to return a string with the human readable arguments, by example using "puts" or just a return of a string. Now I have seen the rescue keyword inside begin-end code, but I wonder how I could catch the ArgumentError when the initialize method is called. Thank you for your answers, feedback and comments!

  • Passing parameters thru Ruby's OAuth

    - by JP
    I'm using Mirven's Twitter OAuth Sinatra example and trying to figure out how I can send a 'next page' parameter with the Oauth request: ie. The user attempts to visit /edit/profile which requires a login so I redirect to /request which deals with login via twitter - I now want to be able to redirect the user to the address they were originally looking for if they log in successfully. I thought I could do this in the .get_request_token line with this code: @request_token = @consumer.get_request_token({:oauth_callback => "http://#{request.host}/auth"},{:next => params['next'] || '/'}) But params has no additional items in the /auth handler. I'm new to OAuth, how would I go about doing this?

  • How to retrieve caller context object in Ruby ?

    - by David
    Hi, hereafter is my piece of code that I want to simplify in order to avoid passing an extra argument on each call : module M def do_something(context) puts "Called from #{context}" end module_function :do_something end class Foo def do_stuff M.do_something(self) end end Foo.new.do_stuff Is there a way to do the same think without passing 'self' as an input argument to 'do_something' method like this ? module M def do_something puts "Called from #{method that returns caller object}" end module_function :do_something end class Foo def do_stuff M.do_something end end Foo.new.do_stuff Thanks for your support!

  • Ruby on Rails: How to use a local variable in a collection_select

    - by mmacaulay
    I have a partial view which I'm passing a local variable into: <%= render :partial => "products/product_row", :locals => { :product => product } %> These are rows in a table, and I want to have a <select> in each row for product categories: <%= collection_select(:product, :category_id, @current_user.categories, :id, :name, options = {:prompt => "-- Select a category --"}, html_options = { :id => "", :class => "product_category" }) %> (Note: the id = "" is there because collection_select tries to give all these select elements the same id.) The problem is that I want to have product.category be selected by default and this doesn't work unless I have an instance variable @product. I can't do this in the controller because this is a collection of products. One way I was able to get around this was to have this line just before the collection_select: <% @product = product %> But this seems very hacky and would be a problem if I ever wanted to have an actual instance variable @product in the controller. I guess one workaround would be to name this instance variable something more specific like @product_select_tmp in hopes of not interfering with anything that might be declared in the controller. This still seems very hacky though, and I'd prefer a cleaner solution. Surely there must be a way to have collection_select use a local variable instead of an instance variable. Note that I've tried a few different ways of calling collection_select with no success: <%= collection_select(product, ... <%= collection_select('product', ... etc. Any help greatly appreciated!
