...ule false => nil >> Object.parent => Object The above indicates that the Class object instance inherits from the Module object instance and the Module object instance inherits from Object. And Object doesn''t inherit from anything. So why do these return true: >> Module.is_a?(Class) => true >> Object.is_a?(Module) => true -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I''m wondering what''s the difference between stub and message expectation with any_number_of_times, for example: myMock = mock("mymock") myMock.stub!(:is_a?).with(MyClass).and_return(false) and myMock = mock("mymock") myMock.should_receive(:is_a?).with(MyClass).any_number_of_times.and_return(false) because is_a? may not be called at all, it just like a stub. Is my understanding correct? Is there any guide how to use stub and message expe...

Hey all, There''s a core Class class and core Object class in Ruby library: http://www.ruby-doc.org/core/classes/Object.html http://www.ruby-doc.org/core/classes/Class.html First, let''s resolve the simple distinction between an Object and Class as envisioned by Smalltalk but within the Ruby context: #A class is a template used to define methods and properties class Hello

Hi, there. I have two validations in the model: validates_numericality_of :value, :only_integer=>true, :allow_blank=>true validates_size_of :value, :is=>9, :message=>"must be 5-digit number", :if=>Proc.new{|u| u.value.is_a?(Numeric)} They work as expected except when the :value is character/string like "a" "abc", the second validation will also output error message "must be 5-digit number". What I want is the second validation displays error message only when the :value is a number. I...

Hi folks. I''ve just started using rspec and I have to say it''s very nice. The thing is, I prefer mocha''s mocking dialect. So I thought a simple require ''mocha'' would set me up. Unfortunately, rspec does all its goodness using do/end blocks in anonymous classes, so it wasn''t quite that obvious. Anyway, here is the incantation I ended up

...nt for Mysql and Oracle, so I have to get database adapter type programmatically in my codes to process different native SQL statements. I haven''t found any document for this situation.

(ActiveRecord::ConnectionAdapters::MysqlAdapter) {Process natvie Mysql SQL statements} end After test, it works. But I am wondering if this i...

...ll that generates a SELECT * type query against a table with a DATETIME column in SQL Server whose value occurs before 1970 will fail, because of the coercion of SQL Server datetime types to Time values in Ruby. See sqlserver_adapter.rb line 490 (record[col] = record[col].to_time if record[col].is_a? DBI::Timestamp) If I remove the coercion (just commenting out that line), I can successfully execute these find() calls. I have a couple of questions: 1) Does anyone know of any adverse effects that I will incur by doing this? 2) Does anyone know when this will be resolved in the sqlserver_ad...

append_features(mod) The documentation says: When this module is included in another, Ruby calls append_features in this module, passing it the receiving module in mod. Ruby’s default implementation is to add the constants, methods, and module variables of this module to mod if this module has not already been added to mod or one of its ancestors. See also Module#include. What if this module is

Hi all, This is odd. It looks to me like we have all 4 variations of memcpy set in Windows::MSVCRT::Buffer but somehow this one creeps up. I actually noticed it in a few cases with that earlier mmap sub/replace example, but I wasn''t sure what was happening. Note that windows-api 0.2.3 and windows-pr-0.8.3 are the latest versions in CVS, but this happens with windows-api-0.2.2 and

In particular rescue_from does not emulate Ruby''s rescue semantics with regard to inheritance. Which is the rationale?
