• Restricting Access in ERB code.

  - by LGFaler

  I am trying to build a CMS using ERB. Is there a way you can give ERB code read-only access to your models? For instance, I want to be able to load any information on my models (Model.all, Model.find_by_slug, Model.find_by_name, Model.other_model.name, etc...), but I don't want to be able to change this data. Can you disable ERB from executing commands that would make database changes (Model.save, Model.update, Model.delete, Model.destroy, etc.)???

• How can I debug a PHP CLI script with xdebug?

  - by Laran Evans

  I haven't quite figured this out. EVERY piece of documentation I've found covers how to use xdebug to debug scripts running in Apache. I need to debug a php CLI script. So, for instance, how do I pass the XDEBUG_SESSION_START variable in to get xdebug to kick on? I'm specifically trying to debug a CakePHP shell. So if anyone has any additional insight into that I'd be very appreciative. Thanks.

• Is it possible to run a Java program inside a Flex application?

  - by Joshua

  I would like to be able to incorporate a simple game, written in Java as a component within a Flex Application. Am I crazy? Flex can display HTML, and SWF, it can also call JavaScript - but can I incorporate an applet somehow? I do NOT mean kludging it in as a sister component within a browser, but actually within the flex application itself, so that it could also run under Adobe Air, for instance.

• Managing a user's PHP session with Cocoa Touch

  - by Calvin L

  I'm building an iPhone app, which will allow users to log in to a PHP web server that authenticates the user and starts a session.

• What is the meaning of method class in the class definition in Ruby?

  - by Steven Xu

  I'm familiar with function definitions and variable declarations being in class definitions: public class MyClass { public int myvar; public void doSomething() { } } But what does it "mean" in Ruby when a method is actually called in the class definition? This happens amply in Rails, for instance: class User < ActiveRecord::Base has_many :posts end What exactly does this do (at a lower level than "it adds some methods to the class")? How would I implement such a function (e.g., one that mixes in some additional methods)?

• Rails - Accessing model class methods from within ActiveRecord model

  - by aaronrussell

  I have a simple standalone model that doesn't inherit from ActiveRecord or anything else, called SmsSender. As the name suggests, it delivers text messages to an SMS gateway. I also have an ActiveRecord model called SmsMessage which has an instance method called deliver: def deliver SmsSender.deliver_message(self) self.update_attributes :status => "Sent" end The above is returning uninitialized constant SmsSender. I'm sure this is dead simple, but how can I access the SmsSender class from within my model?

• Subroutine to apply Daylight Bias to display time in local DST?

  - by vfclists

  UK is currently 1 hour ahead of UTC due to Daylight Savings Time. When I check the Daylight Bias value from GetTimeZoneInformation it is currently -60. Does that mean that translating UTC to DST means DST = UTC + -1 * DaylightBias, ie negate and add? I thought in this case for instance adding Daylight Bias to UTC is the correct operation, hence requiring DaylightBias to be 60 rather than -60.
