Hi! Yesterday I started to write my unit tests for the fist time using rails. I''m using this method: http://blog.codahale.com/2005/12/23/a-rails-howto-simplify-your-unit-tests/ My customer_test.rb looks like this: require File.dirname(__FILE__) + ''/../test_helper'' class CustomerTest < Test::Unit::TestCase fixtures :customers # Replace this with your real

Hello RSpec users, Have been using RSpec since 0.8.2 (not too long ago, I must say). and been creating my custom matchers since was defined as "good practice". Also, auto-generated names for the examples is very helpful, I''m trying to take advantage of it. Since I often prior code/define all the "examples", I have created a few matchers to fulfill associations and

This is pretty much the same as last time around, if you recall. Thanks to Wilson for converting to the new form. I''ve added a few lines. Basically, it iterates over your model associations and does two things. - First, just try to call the association. Usually fixes speeling erors or other such silliness. - Second, try to find a record with an :include on the association. This

Hi, I am learning Single Table Inheritance and have a question. In my application, a message may be written by a user or by a guest. Thus a writer of a message is virtually associated either to a user or a guest. class Message < ActiveRecord::Base end class UserMessage < Message belongs_to :writer, :class_name => ''User'' end class GuestMessage < Message

Hello. I''ve read about examples on inheritance with rails. Here is an example: http://juixe.com/techknow/index.php/2006/06/03/rails-single-table-inheritance/ The way is to add a type field in the table. So if I have an Animal class with an attribute name, I can inherit from this class like: Dog < Animal, Cat < Animal, and so on. With the type field in the table I can do Dog.all,

Hi, It seems like the wxruby homepage has been replaced by a mortgage broker. I do need to refinance, but I was more interested in some documentation on wxruby. Is this a sign that the project is fading into oblivion? If so, I would really like to know what new cross-platform library people are using for developing ruby desktop applications. Josh

Hello all: I am looking at the documentation of the new firewalld service in CentOS 7. It looks like no matter what I configure with it, outgoing connections are still going to be allowed. That does not seem very secure. I always set my servers to default policy of DROP for everything incoming and outgoing and then add rules to allow very specific traffic through. Is this possible using the

I have a very strange problem I'm hoping someone has encountered already. I've scoured the internet for an answer to this one. My phone company provides no disconnect supervision. Hence I'm forced to use the busydetect feature. I have a TDM400 with two FXO ports. If I call from an internal extension to a landline and then hangup the landline Asterisk detects the busy signal

I don't have much experience with r. What I am trying to do is to turn regression coefficients (after I run a lm or glm model) into some matrix such that I can do some post-estimation calculation, for example predicted probabilities in glm model, etc.. Or, is there any function in r that I can use to do something along that line? thanks. Jun Xu, Ph.D. Department of Sociology Ball State

Hello all: I did a fresh install of CentOS 7 on a new machine. I wrote /usr/local/bin/firewall.stop to remove all the firewall rules. It contains this code: # Flush the rules /usr/sbin/iptables -F # Set the default policies to accept /usr/sbin/iptables -P INPUT ACCEPT /usr/sbin/iptables -P OUTPUT ACCEPT /usr/sbin/iptables -P FORWARD ACCEPT I wrote /usr/local/bin/firewall.start to set the

I have a wizard which consists of two pages. To keep it simple let''s say that the first page asks the user to select a state from the drop down menu. In case the user doesn''t select any state, an error message needs to be displayed. Ideally I would like to do something like this. def new selected_value = params[:addevent][:state_id] if selected_value == "-1"

class Event < ActiveRecord::Base belongs_to :venue belongs_to :category end class Venue < ActiveRecord::Base belongs_to :city end class City < ActiveRecord::Base belongs_to :state end I want to retrieve all event records belonging to a state.

Hi friends! I''m relatively new with Rails and I''m struggling for a long time with this problem (it should have a pattern solution but until now I didn''t find it): I have the following models: Institution, City, State and Country. class Country < ActiveRecord::Base has_many :states has_many :cities, :through => :states end # == Schema Information # Table

I have these tables set up like this: listings has_many :states <field>state_id [int] <other fields.... .............. .............> states belongs_to: listings <field>name <other fields.. ............... .................> In my view I have <%= listing.name %> have also tried listing.state_id.name , that didn''t seem to do the magic either. This

I''m trying to implement acts_as_rateable to my Beast installation to give users the option to rate posts (like reddit). I chose acts_as_rateable as it supposedly easily allows reddit-type voting but I''m having some problems setting it up and the documentation seems outdated. (http://www.juixe.com/techknow/index.php/2006/07/05/acts-as-rateable-plugin/) So far, I''ve
