• Ruby Metaprogramming

  - by Veerendra Manikonda

  I am having a method which returns the price of a given symbol and i am writing a test for that method. This is my test def setup @asset = NetAssetValue.new end def test_retrieve_price_for_symbol_YHOO assert_equal(33.987, @asset.retrieve_price_for_a_symbol('YHOO')) end def test_retrive_price_for_YHOO def self.retrieve_price_for_a_symbol(symbol) 33.77 end assert_equal(33.97, @asset.retrieve_price_for_a_symbol('YHOO')) end This is my method. def retrieve_price_for_a_symbol(symbol) symbol_price = { "YHOO" => 33.987, "UPS" => 35.345, "T" => 80.90 } raise Exception if(symbol_price[symbol].nil?) symbol_price[symbol] end I am trying to mock the retrieve_price_for_a_symbol method by writing same method in test class but when i call it, the call is happening to method in main class not in the test class. How do I add that method to meta class from test and how do i call it? Please help.

• Subprocess statement works in python console but not work in Serverdensity plugin?

  - by maxigs

  in the python console the following statement works perfectly fine (i guess using eval that way is not really good, but its just for testing purpose in this case and will be replaced with proper parsing) $ python >>> import subprocess >>> r = subprocess.Popen(['/home/kupferwerk/sd-agent-plugins/plugin1.rb'], stdout=subprocess.PIPE, close_fds=True).communicate()[0] >>> data = eval(r) >>> data {'test': 1} when i convert this into a Serverdensity plugin however it keeps crashing the agent.py daemon everytime it executes the plugin. i was able to narrow it down to the subprocess line but could not find out why. exception catching did not seem to work also. here how the plugin looks like: class plugin1: def run(self): r = subprocess.Popen(['/pathto/plugin1.rb'], stdout=subprocess.PIPE, close_fds=True).communicate()[0] data = eval(r) return data I'm quite new to work with python and cant really figure out why this wont work. Thanks a lot for ideas :)

• How to implement action in didSelectRowAtIndexPath of UITableview?

  - by Sumana Mehta

  On my view, I used to have few buttons and each button had an action associated with it. UIButton *testButton = [[UIButton alloc] initWithFrame:CGRectMake(120,300,90,90)]; [testButton setBackgroundImage:[UIImage imageNamed:@"test.jpg"] forState:UIControlStateNormal]; [testButton addTarget:self.view action:@selector(gotoProd:) forControlEvents:UIControlEventTouchUpInside]; [testButton addt [scrollView testButton]; But now I am trying to replace all those buttons with the tableview with rows. I was able to populate the rows and I know one needs to use didSelectRowAtIndexPath for handling on select event of the cell. But how can I implement action:@selector(gotoProd:) in tableviews ?? Any help will be greatly appreciated.

• Call random function on percents?

  - by Angelena Godkin

  I cannot figure this out. I need a solution to call a random function for it's percent. Ex. there is 10% chances that the script calls subscriptions() and 3% chance that the system call the function "specialitems()". I am stuck in this, so i hope someone can help me with this brainkiller. <?php class RandomGifts { public $chances = ''; public function __construct($user) { $this->user = $user; //Find percent for each function $this->chances = array( 'subscriptions' => 10, // 10% 'specialitems' => 3, // 5% 'normalitems' => 30, // 40% 'fuser' => 50, // 70% 'giftcards' => 7, // 7% ); //This should call the function which has been calculated. self::callFunction(?); } public function subscriptions(){} public function specialitems(){} public function normalitems(){} public function fuser(){} public function giftcards(){} } ?>

• TabBars and iOS 7

  - by MichaelScaria

  I have a UITabbarController that I'm pushing another controller on top of using a UINavigationController. On iOS 6 and below, the tabBar of the parent controller slides away and the toolbar of the new view controller is presented. But on iOS 7 the tabBar doesn't animate away even if I run the code [self.navigationController setToolbarHidden:YES animated:NO]; EDIT - Okay I narrowed my problem to iOS 7 not respecting the hidesBottomBarWhenPushed property, I followed the answers in hidesBottomBarWhenPushed ignored in iOS 7 but it didn't work. The view that is pushed has a toolbar with buttons and the buttons are responding to touches, it's just that the tabBar is on top of the toolbar.

• Own params to PeriodicTask run() method in Celery

  - by Alex Isayko

  Hello to all! I am writing a small Django application and I should be able to create for each model object its periodical task which will be executed with a certain interval. I'm use for this a Celery application, but i can't understand one thing: class ProcessQueryTask(PeriodicTask): run_every = timedelta(minutes=1) def run(self, query_task_pk, **kwargs): logging.info('Process celery task for QueryTask %d' % query_task_pk) task = QueryTask.objects.get(pk=query_task_pk) task.exec_task() return True Then i'm do following: >>> from tasks.tasks import ProcessQueryTask >>> result1 = ProcessQueryTask.delay(query_task_pk=1) >>> result2 = ProcessQueryTask.delay(query_task_pk=2) First call is success, but other periodical calls returning the error - TypeError: run() takes exactly 2 non-keyword arguments (1 given) in celeryd server. So, can i pass own params to PeriodicTask run() ? Thanks!

• Use SQL to clone data in two tables that have a 1-1 relationship with each other

  - by AmoebaMan17

  Using MS SQL 2005, Table 1 ID | T1Value | T2ID | GroupID ---------------------------------- 1 | a | 10 | 1 2 | b | 11 | 1 3 | c | 12 | 1 4 | a | 22 | 2 Table 2 ID | T2Value ---------------- 10 | H 11 | J 12 | K 22 | H I want to clone the data for GroupID == 1 into a new GroupID so that I result with the following: Table 1 ID | T1Value | T2ID | GroupID ---------------------------------- 1 | a | 10 | 1 2 | b | 11 | 1 3 | c | 12 | 1 4 | a | 22 | 2 5 | a | 23 | 3 6 | b | 24 | 3 7 | c | 25 | 3 Table 2 ID | T2Value ---------------- 10 | H 11 | J 12 | K 22 | H 23 | H 24 | J 25 | K I've found some SQL clone patterns that allow me to clone data in the same table well... but as I start to deal with cloning data in two tables at the same time and then linking up the new rows correctly... that's just not something I feel like I have a good grasp of. I thought I could do some self-joins to deal with this, but I am worried in the cases where the non-key fields have the same data in multiple rows.

• javascript: what are immediate functions used for [duplicate]

  - by tkoomzaaskz

  This question already has an answer here: Why using self executing function in JavaScript? [duplicate] 4 answers I've been programming in JS since some time, but I have never came upon a need of using immediate functions, for example: (function(){ console.log('hello, I am an immediate function'); }()) What would be the difference if I just wrote: console.log('hello, I am an immediate function'); ? I don't have any access to this function anyway (it is not assigned anywhere). I think (but I'm not sure) that I can implement everything without immediate functions - so why do people use it?

• Actual SQL statement after bind variables specified

  - by bioffe

  I am trying to log every SQL statement executed from my scripts. However I contemplate one problem I can not overcome. Is there a way to compute actual SQL statement after bind variables were specified. In SQLite I had to compute the statement to be executed manually, using code below: def __sql_to_str__(self, value,args): for p in args: if type(p) is IntType or p is None: value = value.replace("?", str(p) ,1) else: value = value.replace("?",'\'' + p + '\'',1) return value It seems CX_Oracle has cursor.parse() facilities. But I can't figure out how to trick CX_Oracle to compute my query before its execution.

• Settings cell selected background view removes backgroundview

• Best way to make an attribute always an array?

  - by Shadowfirebird

  I'm using my MOO project to teach myself Test Driven Design, and it's taking me interesting places. For example, I wrote a test that said an attribute on a particular object should always return an array, so -- t = Thing.new("test") p t.names #-> ["test"] t.names = nil p t.names #-> [] The code I have for this is okay, but it doesn't seem terribly ruby to me: class Thing def initialize(names) self.names = names end def names=(n) n = [] if n.nil? n = [n] unless n.instance_of?(Array) @names = n end attr_reader :names end Is there a more elegant, Ruby-ish way of doing this? (NB: if anyone wants to tell me why this is a dumb test to write, that would be interesting too...)

• Multiple HTTP request - Rails

  - by bradleyg

  My application checks a number of domains to see if they are valid (approx 100). I have the following code to check a single domain: def self.test_url uri, limit = 10 if limit == 0 return get_error_messages("001") end begin url = URI.parse(uri) response = Net::HTTP.start(url.host, url.port).request_head('/') rescue SocketError => e return get_error_messages("002") end case response when Net::HTTPRedirection then test_url(response['location'], limit - 1) else return get_error_messages(response.code) end end The code checks for the response code while taking into account redirects. This works fine. The only problem I have is when I put this in a loop I want it to run in parallel. So I don't have to wait for domain 1 to respond before I can request domain 2. I have managed this in PHP using curl_multi to run the requests in parallel. Is there a similar thing I can do in Rails?

• How to connect Model through Controller to View using bindings?

  - by Paperflyer

  I have an NSTextField in my view. Its value is bound to an NSNumber *number in my controller. The controller simply calls through to the model (value) to get the appropriate value. // In the controller - (NSNumber *)number { return [NSNumber numberWithFloat:[model value]]; } - (void)setNumber:(NSNumber *)aNumber { [model setValue:[aNumber floatValue]]; } This is fine, only the controller is not notified of model changes and thus, changing the value in the model does not update the NSTextField. The only other option I can think of is to have the model notify the controller and the controller manually update the view through an Outlet. But this circumvents the binding. // In the model, after value change [[NSNotificationCenter defaultCenter] postNotificationName:@"ValueChanged" object:self]; // In the controller, after being notified - (void)updateView:(NSNotification *)aNotification { [myTextField setFloatValue:[model value]]; } Is there a better, binding-aware way to implement this communication?

• Using iPhone Core Data to many Relationship

  - by BLeB

  When I define a to many relationship between entities in Xcode and then generate the data class from the entity I get a header with the following methods defined: @interface PriceList (CoreDataGeneratedAccessors) - (void)addItemsObject:(PriceListItem *)value; - (void)removeItemsObject:(PriceListItem *)value; - (void)addItems:(NSSet *)value; - (void)removeItems:(NSSet *)value; @end When I attempt to call addItemsObject with the following code a doesNotRecognizeSelector exception is thrown. PriceListItem *item = [NSEntityDescription insertNewObjectForEntityForName:@"PriceListItem" inManagedObjectContext:managedObjectContext]; item.cat = [attributeDict valueForKey:@"c"]; item.sel = [attributeDict valueForKey:@"s"]; [self addItemsObject:item]; From what I have read I do not have to implement these methods and that they are generated at runtime. Any ideas?

• super-space-optimized code

  - by Will

  There are key self-contained algorithms - particularly cryptography-related such as AES, RSA, SHA1 etc - which you can find many implementations of for free on the internet. Some are written to be nice and portable clean C. Some are written to be fast - often with macros, and explicit unrolling. As far as I can tell, none are trying to be especially super-small - so I'm resigned to writing my own - explicitly AES128 decryption and SHA1 for ARM THUMB2. What patterns and tricks can I use to do so? Are there compilers/tools that can roll-up code?

• Seeking assistance with Escaping Data for MySQL queries

  - by JM4

  Please don't send me a link to php.net referencing mysql_real_escape_string as the only response. I have read through the page and while I understand the general concepts, I am having some trouble based on how my INSERT statement is currently built. Today, I am using the following: $sql = "INSERT INTO tablename VALUES ('', '$_SESSION['Member1FirstName'], '$_SESSION['Member1LastName'], '$_SESSION['Member1ID'], '$_SESSION['Member2FirstName'], '$_SESSION['Member2LastName'], '$_SESSION['Member2ID'] .... and the list goes on for 20+ members with some other values entered. It seems most people in the examples already have all their data stored in an array. On my site, I accept form inputs, action="" is set to self, php validation takes place and if validation passes, data is stored into SESSION variables on page 2 then redirected to the next page in the process (page 3) (approximately 8-10 pages in the whole process). thanks!

• Generating incremental numeric column values during INSERT SELECT statement

  - by Charles

  I need to copy some data from one table to another in Oracle, while generating incremental values for a numeric column in the new table. This is a once-only exercise with a trivial number of rows (100). I have an adequate solution to this problem but I'm curious to know if there is a more elegant way. I'm doing it with a temporary sequence, like so: CREATE SEQUENCE temp_seq START WITH 1; INSERT INTO new_table (new_col, copied_col1, copied_col2) SELECT temp_seq.NEXTVAL, o.* FROM (SELECT old_col1, old_col2 FROM old_table) o; DROP SEQUENCE temp_seq; Is there way to do with without creating the sequence or any other temporary object? Specifically, can this be done with a self-contained INSERT SELECT statement? There are similar questions, but I believe the specifics of my question are original to SO.

• Documents/Images display fine in Simulator, but not on my device

  - by Phamer

  Hello. My application is running fine on the simulator, but not on the device. Basically, any documents from the web (PDF, Word, M4P videos) are working great on the simulator (and can be accessed from Safari on the iPhone). However, running on the iPhone, they don't display anything. Here's some sample code: // Set up the URL documentViewController.documentUrl = [NSURL URLWithString:[NSString stringWithFormat:mobileContentUrl]]; // mobileContentUrl is something like: http://www.myserver.com/pathitem/Video.mp4" and can be accessed from Safari [self.navigationController pushViewController:documentViewController animated:YES]; Within documentViewController I have: - (void)viewDidLoad { [super viewDidLoad]; [webView loadRequest:[NSURLRequest requestWithURL:documentUrl]]; } As I said, works like a charm in the Simulator...What could possibly causing this NOT to work on iPhone? How do I debug the issue???
