I have the following code, which yields instance eval''s the block given: class Foo def bar(&blk) instance_eval &blk end def baz yield end end The effect of this is that self is reassigned: Foo.new.bar do # here, self is the instance of Foo # created by new end But normally self is the object in which Foo.new.bar {...} occurs. Foo.new.baz do # self is the execution conte...

Hi All, Got a bit of a Ruby question for you. If I have a function that makes a proc object like this: def select(selector, &proc) el = Element.new el.instance_eval proc end select("#thing") do hide end Wat I want to do is evaluate the Proc in the context of el but this doesn''t work because instance_eval accepts a string or a block and not a Proc object. I sense Im barking up the wrong tree here entirely but Im pretty new to this Rub...

I''m trying to add some per-object behaviors to objects descended from ActiveRecord, by using after_initialize() and instance_eval(), like this: def after_initialize self.instance_eval(File.read(''customers/default.rb'')) end (Ultimately the file path will be dynamic, this is just proof of concept.) default.rb just contains a few method definitions like this one: def support_phone_num "1-800-OBI...

...es not re-evaluate the filters on every run. If you are filtering access based on parameters, this can be bad. The scope is set on the first request and then further requests use the last generated scoping. The initial part of ScopedAccess::Filter#before looks like this: @scoping = controller.instance_eval(@scoping.to_s) if @scoping.is_a?(Symbol) This makes @scoping not a symbol on the first run and @scoping will never be evaluated again. This would fail in code which looks like this: For example: def silo_filter(klass) filter = ScopedAccess::ClassScoping.new klass, :silo_id => @silo.i...

Hi, Has anyone experiences using SwitchTower (Windows) in a shared hosting environment (Textdrive)? I already patched the SwitchTower rake tasks (I don''t know if someone is interested on it), but i still experience some problems (not in the sudoers list, ...). Thank you for answer (and thank you to the textdrive guys, i never had a such fast support!) -- Jean-Etienne Durand

Is there any reason why a stub couldn''t both yield and return? I''m looking for a way to mock out a class I''ve made named "AnonymousClass": class AnonymousClass def initialize(&blk) @klass = Class.new @klass.instance_eval(&blk) if block_given? end def new @klass.new end def evaluate(&blk) @klass.instance_eval(&blk) end attr_reader :klass alias_method :class, :klass end One of the behaviours of the AnonymousClass is that new can take a block, and eval the block in th...

I have a few questions regarding using activerecord outside of rails. Usage is with legacy databases, which gives rise to some of the problems. Probably the first, and most simple question though, is how to capture the SQL log, with which I can hopefully figure the other stuff out. I''m currently trying ActiveRecord::Base.logger = Logger.new STDOUT Based on random googles, but it

This is part of a rails project. The following method is part of the Ams class (a rails model). I''m a bit unsure of the rspec/bdd way of testing this method. def persist_as_domains @current_domains.each do |d| dom = Domain.new dom.domain = d dom.source_id = 1 dom.at = Time.now dom.save end end The following is what came out when I tried to write my test.

Ok, given the statement on the web page about unlesssystemuser under Resources ( http://reductivelabs.com/projects/puppet/documentation/typedocs.html#resources), I assume that users can be purged. However, when I attempt to do this with resources { user: purge => true, noop => true } and what I get is: err: Found a bug: private method ''split'' called for nil:NilClass.
