I was wondering if there was a way to make controller methods in rails available only for specific HTTP methods (GET, POST, etc.).
I guess I can create a filter to do that but it seems to me that it is something that is available out-of-the-box in rails.
Is it?
I'm currently working on an emulation server for a flash-client based game, which has a "pets system", and I was wondering if there was a simpler way of going about checking the level of specified pets.
Current code:
public int Level
{
get
{
if (Expirience 100) // Level 2
{
if (Expirience 200) // Level 3
{
if (Expirience 400) // Level 4 - Unsure of Goal
{
if (Expirience 600) // Level 5 - Unsure of Goal
{
if (Expirience 1000) // Level 6
{
if (Expirience 1300) // Level 7
{
if (Expirience 1800) // Level 8
{
if (Expirience 2400) // Level 9
{
if (Expirience 3200) // Level 10
{
if (Expirience 4300) // Level 11
{
if (Expirience 7200) // Level 12 - Unsure of Goal
{
if (Expirience 8500) // Level 13 - Unsure of Goal
{
if (Expirience 10100) // Level 14
{
if (Expirience 13300) // Level 15
{
if (Expirience 17500) // Level 16
{
if (Expirience 23000) // Level 17
{
return 17; // Bored
}
return 16;
}
return 15;
}
return 14;
}
return 13;
}
return 12;
}
return 11;
}
return 10;
}
return 9;
}
return 8;
}
return 7;
}
return 6;
}
return 5;
}
return 4;
}
return 3;
}
return 2;
}
return 1;
}
}
Yes, I'm aware I've misspelt Experience, I had made the mistake in a previous function and hadn't gotten around to updating everything... :P
I have a bunch of PHP files with classes, in them (although I can't be 100% sure that they won't have code outside of classes in them too), and I need to parse these files to get information about the classes, such as the names of the classes, the methods, the properties, whether they are private/public/static, etc. I looked at PHP's reflection classes and this is very close to what I want but the reflection doesn't seem to use external files and it appears to need to define the classes first. I need to make sure that none of the code is executed and I will be editing the files so I can't guarantee that they will even be error-free.
Any suggestions?
Thanks.
I would like to fix up some error messages my site generates. Here is the problem:
class Brand < ActiveRecord::Base
validates_presence_of :foo
...
end
My goal is to make a message "Ticket description is required" instead of "Foo is required" or may not be blank, or whatever.
The reason this is so important is because lets say previously the field was ticket_summary. That was great and the server was coded to use that, but now due to crazy-insane business analysts it has been determined that ticket_summary is a poor name, and should be ticket_description. Now I don't necessarily want to have my db be driven by the user requirements for field names, especially since they can change frequently without functionality changes.
Is there a mechanism for providing this already?
I have to develop a silverlight application which will run intranet.
It will show local town map and have some images over the map like pushpins. I can use Deep Zoom for map application. But adding images and events for images is not supported.
For silverlight 2, there is DeepEarth api for this. But How can I do this with Silverlight 3?
I currently have an array of around 8 - 10 numbers that changes on a periodic basis.
So around every 5 - 10 seconds the numbers get updated.
I need to get the top 3 numbers in the array every 10 seconds.
This is all done on a mobile device.
At the minute I iterate through the array 3 times and each time I take out the three highest numbers and place them in three previously declared variables.
My question is what should I look to do to increase speed and efficiency in this instance?
Consider you have the following class
public class OuterClass {
...
private static class InnerClass {
int foo;
int bar;
}
}
I think I've read somewhere (but not the official Java Tutorial) that if I would declare the static member classes attributes private, the compiler had to generate some sort of accessor methods so that the outer class can actually access the static member class's (which is effectively a package-private top level class) attributes.
Any ideas on that?
I'm reading the gcc manual at the moment, especially the part about warning/error flags. After reading the part about the -Wextra flag, I wonder if it is useful at all. It seems that it complains about things which seem to be rather subjective or a matter of taste. I'm not that experienced with gcc, I only use it from time to time for some small projects at university, so to all experienced C/C++ (or for whatever language you use gcc), what's the deal with -Wextra?
I have the following code, which just print the key/value pairs in a dict (the pairs are sorted by keys):
for word, count in sorted(count_words(filename).items()):
print word, count
However, calling iteritems() instead of items() produces the same output
for word, count in sorted(count_words(filename).iteritems()):
print word, count
Now, which one should I choose in this situation? I consulted the Python tutorial but it doesn't really answer my question.
Is it possible to use the class methods of some NSObject I've made to controls all existing instances?
I want a delegate class to be able to send messages to the Object's class methods which can then react appropriately with everything out there.
Consider this piece of code:
public abstract class Validator
{
protected Validator()
{
}
protected abstract void ValidateCore(object instance, string value, IList<ValidationResult> results);
public void Validate(object instance, string value, IList<ValidationResult> results)
{
if (null == instance) throw new ArgumentNullException("instance");
if (null == results) throw new ArgumentNullException("results");
ValidateCore(instance, value, results);
}
}
Look at the Validate() overload, how can an abstract class have definitions like this?
I have a column of states, and, depending on the query, I want to order by results by a particular state, then by id (Asc or Desc, depending). For instance, I might want to show all rows with state "HI", sorted by ID desc, and then all the other rows, sorted by id desc.
I was hoping I could do this in one query, rather than getting all my favored state results, and then getting the rest. Can I?

Hi All..
Normally when I am writing the perl program . I used to include following package .
use strict ;
use warnings ;
use Data::Dumper ;
Now , I want like this, I will not include all this package for every program . for that
I will have these all package in my own package. like following.
my_packages.pm
package my_packages ;
{
use strict ;
use warnings ;
use Data::Dumper;
}
1;
So, that if I add my_packages.pm in perl program , it needs have all above packages .
Actually I have done this experimentation . But I am not able get this things .
which means when I am using my_packages . I am not able get the functionality of "use strict, use warnings , use Data::Dumper ".
Someone help me out of this problem.....
Hey guys,
I'm learning myself to go from function based PHP coding to OOP. And this is the situation:
ClassA holds many basic tool methods (functions). it's __construct makes a DB connection.
ClassB holds specific methods based on a certain activity (extract widgets). ClassB extends ClassA because it uses some of the basic tools in there e.g. a database call.
In a php file I create a $a_class = new ClassA object (thus a new DB connection).
Now I need a method in ClassB. I do $b_class = new ClassB; and call a method, which uses a method from it's parent:: ClassA.
In this example, i'm having ClassA 'used' twice. Onces as object, and onces via a parent:: call, so ClassA creates another DB connection (or not?).
So what is the best setup for this basic classes parent, child (extend) situation? I only want to make one connection of course?
I don't like to forward the object to ClassB like this $b_class = new ClassB($a_object); or is that the best way?
Thanks for thinking with me, and helping :d

I want to programatically add multiple UIButtons to a view - the number of buttons is unknown at compile time.
I can make one or more UIButton's like so (in a loop, but shorted for simplicity):
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[button addTarget:self
action:@selector(buttonClicked:)
forControlEvents:UIControlEventTouchDown];
[button setTitle:@"Button x" forState:UIControlStateNormal];
button.frame = CGRectMake(100.0, 100.0, 120.0, 50.0);
[view addSubview:button];
Copied/Edited from this link:
http://stackoverflow.com/questions/1378765/how-do-i-create-a-basic-uibutton-programmatically
But how do I determine in buttonClicked: which button was clicked? I'd like to pass tag data if possible to identify the button.
