  • How to change the sorting of a view using hook_views_pre_view()?

    - by RD
    I've got the following: function view_sorter_views_pre_view(&$view) { // don't need $items if ($view->name == 'MOST_RECENT') { $insert = array(); $insert[order] = 'DESC'; //SORT ORDER $insert[id] = 'title'; $insert[table] = 'node'; $insert[field] = 'title'; $insert[override] = array(); $insert[override][button] = 'Override'; $insert[relationship] = 'none'; unset ($view->display['default']->display_options['sorts']['title']); $view->display['default']->display_options['sorts']['title'] = $insert; } } Basically, I'm just changing the sort order... but this does not appear on the view when opening it. Any idea why?

    - by Khushi
    I have a default page which loads different controls on pageload according to the querystring. I have a control which creates checkbox list (inside div_A) on load and get checkbox checked through database, then i click Continue, div_A get invisible with all the checked checkbox id in hidden field and div_B is visible true. On Go Back click, div_B is visible false and div_A get visible true and following javascript is fired to check the selected checkbox, but it does not work Javascript : function goBack() { var SIds = document.getElementById("<%=hdv_Data.ClientID %>").value; // hdv_Data is the hidden field var Ids_Arr = new Array(); Ids_Arr = SIds.split(','); for (j = 0; j < Ids_Arr.length; j++) { if(Ids_Arr[j] != 0) { alert(Ids_Arr[j]); // works till here, gets correct values in array var chk = document.getElementById(Ids_Arr[j]); alert(chk); chk.checked = true; } } }

  • Most efficient way of checking for a return from a function call in Perl

    - by Gaurav Dadhania
    I want to add the return value from the function call to an array iff something is returned (not by default, i.e. if I have a return statement in the subroutine.) so I'm using unshift @{$errors}, "HashValidator::$vfunction($hashref)"; but this actually adds the string of the function call to the array. I also tried unshift @{$errors}, $temp if defined my $temp = "HashValidator::$vfunction($hashref)"; with the same result. What would a perl one-liner look like that does this efficiently (I know I can do the ugly, multi-line check but I want to learn). Thanks,

  • Update Magento Special Price

    - by Farid
    I'm trying to revert "special price" after the "special price to date" passed to null. So basically when I update my products special price programmatically using this code : $todayDate = Mage::app()->getLocale()->date()->toString(Varien_Date::DATETIME_INTERNAL_FORMAT); $collection = Mage::getModel('catalog/product')->getCollection() ->addStoreFilter() ->addAttributeToFilter('special_price', array('gt' => 0)) ->addAttributeToFilter('special_to_date', array('date' => true, 'to' => $todayDate)); echo "Total products found : ".count($collection); foreach ($collection as $product) { $product->setSpecialPrice(null) ->setSpecialFromDate(null) ->setSpecialToDate(null) ->save(); } echo "<br/> Done!"; But after I update my special price to null the magento product wizard does not let me set a new special price for my product. When I save the form it does not give me any error nor affect any changes in special price and it's still null! What's wrong?!

  • Adding to arrays and printing arrays in Java

    - by nfoggia
    I need help figuring out how to get the user to input a number of integers no more than 10, and then add them to an array and print them out from the array. The code I have below, when run, asks the user for the integers and then runs forever and doesn't work. What am I doing wrong? public static void main(String[] args) { Scanner input = new Scanner(System.in); // create a new scanner System.out.print("Enter integers between 1 and 100\n "); int[] nextNumber = new int[10]; int i = 0; int number = input.nextInt(); while (i < nextNumber.length){ i++; nextNumber[i] = number; number = input.nextInt(); } int a = 0; while (a < nextNumber.length){ a++; System.out.println(nextNumber[a]); }

  • Is there a faster method then StringBuilder for a max 9-10 step string concatenation?

    - by Pentium10
    I have this code to concate some array elements: StringBuilder sb = new StringBuilder(); private RatedMessage joinMessage(int step, boolean isresult) { sb.delete(0, sb.length()); for (int i = 0; i <= step; i++) { if (mStack[i] == null) continue; rm = mStack[i].getCurrentMsg(); if (rm == null || rm.msg.length() == 0) continue; if (sb.length() != 0) { sb.append(", "); } sb.append(rm.msg); } return sb.toString(); } Important the array holds max 10 items, so it's not quite much. My trace output tells me this method is called 18864 times, 16% of the runtime was spent in this method. Can I optimize more?

It work only on the same session. On different sessionthe json built start from the beginning. Any idea about that?

  • [Ruby] How can I randomly iterate through a large Range?

    - by void
    I would like to randomly iterate through a range. Each value will be visited only once and all values will eventually be visited. For example: (0..9).sort_by{rand}.map{|x| f(x)} where f(x) is some function that operates on each value. A Fisher-Yates shuffle could be used to increase efficiency, but this code is sufficient for many purposes. My problem is that sort_by will transform the range into an array, which is not cool because I am working with astronomically large numbers. Ruby will quickly consume a large amount of RAM trying to create a monstrous array. This is also why the following code will not work: tried = {} # store previous attempts bigint = 99**99 bigint.times { x = rand(bigint) redo if tried[x] tried[x] = true f(x) # some function } This code is very naive and quickly runs out of memory as tried obtains more entries. What sort of algorithm can accomplish what I am trying to do?

  • OpenID PAM module

    - by Harvey Kwok
    I am looking for a PAM module that can use OpenID to do the authentication. My idea is that I want to logon my Linux box using my gmail account and password. I found there is a open source project in Google Code which seems to be doing the things I want but I don't see any code available for download. I saw there are so many examples or implementations but they are all about web apps. Is there any non-web based OpenID applications in the world? Is it technically possible to make a non-web based OpenID application? I naively think that it should be possible. I can emulate whatever packets the browser send out to the OpenID provider and get back the result. As long as my Linux box is connected to the Internet, I should be able to use my OpenID to login. Appreciate any comments, suggestions or pointers on how to make an OpenID PAM module. Thanks!

  • Better data-structure design

    - by Tempname
    Currently in my application I have a single table that is giving me a bit of trouble. The issue at hand is I have a value object that is mapped to this table. When the data is returned to me as an array of value objects, I have to then loop through this array and begin my recursion by matching the ParentID to parent ObjectID's. The column ParentID is either null (acts a parent) or it holds the value of an ObjectID. I know there has to be a better way to create this data structure so that I do not have to do recursive loops to match ParentID's with their ObjectID's. Any help with this is greatly appreciated. Here is the table in describe form: +----------------+------------------+------+-----+---------------------+-----------------------------+ | Field | Type | Null | Key | Default | Extra | +----------------+------------------+------+-----+---------------------+-----------------------------+ | ObjectID | int(11) unsigned | NO | PRI | NULL | auto_increment | | ObjectHeight | decimal(6,2) | NO | | NULL | | | ObjectWidth | decimal(6,2) | NO | | NULL | | | ObjectX | decimal(6,2) | NO | | NULL | | | ObjectY | decimal(6,2) | NO | | NULL | | | ObjectLabel | varchar(255) | NO | | NULL | | | TemplateID | int(11) unsigned | NO | MUL | NULL | | | ObjectTypeID | int(11) unsigned | NO | MUL | NULL | | | ParentID | int(11) unsigned | YES | MUL | NULL | | | CreationDate | datetime | YES | | 0000-00-00 00:00:00 | | | LastModifyDate | timestamp | YES | | NULL | on update CURRENT_TIMESTAMP | +----------------+------------------+------+-----+---------------------+-----------------------------+e

  • Returning messages in Smalltalk

    - by Zachary
    I have a Dictionary of objects I have created in smalltalk, which I am iterating over by enumerating it based on the key/value pairs. For value object in the dictionary, I am calling a method on that object. Based on certain conditions, I would like for this object to be able to add a new member to dictionary, and possibly delete another one. I've been looking at the 'Perform' and 'Messages' facilities in Smalltalk, but I'm not sure if it is even possible to do what I'm trying to do - is it possible to return a message (or multiple messages), which another object can process and perform? For example, could my method return 'removeKey: 19' and 'add object' at the same time? I am using GNU Smalltalk, if it matters.

  • More elegant way to parse inline variables in strings

    - by Tom
    Currently I have this: function parse_string($string, $variables){ extract($variables); return eval('return "'. addcslashes($string, '"') .'";'); } So I can input this string: 'Hi {$name}, my name is {$own_name}' Together with this array: array('name' => 'John', 'own_name' => 'Tom') And get this back: 'Hi John, my name is Tom'   I've never liked this eval() approach but it works and it's fast (faster than regex at least). Question: Is there a more elegant way to do this (faster than using regex) in PHP5?

  • SQLite/iPhone read copyright symbol

    - by Marco A
    Hi All, I am having problems reading the copyright symbol from a sqlite db that I have for my App that I am developing. I import the information manually, ie, from an excel sheet. I have tried two ways of doing it and failed with both: 1) Tried replacing the copyright symbol with "\u00ae" (unicode combination) within excel and then importing the modified file. - Result: I get the combination of \u00ae as a part of the string, it doesnt detect the unicode combination. 2) Tried leaving as it is. Importing the excel with the copyright symbol. - Result: I get a symbol that is different from the copyright, its something like an AE put together.looks like this: Æ Heres my code how I read from DB: -(void) readCategoriesFromDatabase:(NSString *) rest_input { // Init the products Array categories = [[NSMutableArray alloc] init]; // Open the database from the users filessytem rest_input = [rest_input stringByAppendingString:@"'"]; NSString *newString; newString = [@"select distinct category from food where restaurant='" stringByAppendingString:rest_input]; const char *cat_sqlStatement = [newString UTF8String]; sqlite3_stmt *cat_compiledStatement; if(sqlite3_prepare_v2(database, cat_sqlStatement, -1, &cat_compiledStatement, NULL) == SQLITE_OK) { // Loop through the results and add them to the feeds array while(sqlite3_step(cat_compiledStatement) == SQLITE_ROW) { NSString *catName = [NSString stringWithUTF8String:(char *)sqlite3_column_text(cat_compiledStatement,0)]; // Create a new product object with the data from the database Product *category = [[Product alloc] initWithName:catName]; // Add the product object to the respective Array [categories addObject:category]; [category release]; } sqlite3_finalize(cat_compiledStatement); } NSLog(@"Finished Accessing Database to gather Categories...."); } I open the DB with this function: -(void) checkAndCreateDatabase{ NSLog(@"Checking/Creating Database...."); NSFileManager *fileManager = [NSFileManager defaultManager]; success = [fileManager fileExistsAtPath:databasePath]; [fileManager removeFileAtPath:databasePath handler:nil]; NSString *databasePathFromApp = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:databaseName]; [fileManager copyItemAtPath:databasePathFromApp toPath:databasePath error:nil]; [fileManager release]; if (sqlite3_open([databasePath UTF8String], &database) != SQLITE_OK) { sqlite3_close(database); database = nil; } NSLog(@"Finished Checking/Creating Database...."); } Thanks to anything that can help me out.

  • python dictionary with constant value-type

    - by s.kap
    hi there, I bumped into a case where I need a big (=huge) python dictionary, which turned to be quite memory-consuming. However, since all of the values are of a single type (long) - as well as the keys, I figured I can use python (or numpy, doesn't really matter) array for the values ; and wrap the needed interface (in: x ; out: d[x]) with an object which actually uses these arrays for the keys and values storage. I can use a index-conversion object (input -- index, of 1..n, where n is the different-values counter), and return array[index]. I can elaborate on some techniques of how to implement such an indexing-methods with reasonable memory requirement, it works and even pretty good. However, I wonder if there is such a data-structure-object already exists (in python, or wrapped to python from C/++), in any package (I checked collections, and some Google searches). Any comment will be welcome, thanks.

  • What's the proper way of importing option lists into an Android app?

    - by Scott
    I have been storing option lists for my Android app in a cloud table. For example, categories like "historical fiction","biography","science fiction", etc. I see the following pros and cons: Pro: I can make changes to the list without sending an app update to Google Play Not normalized - I can use the text in my other data tables instead of a reference ID Con: App needs to take time to download from the web each time (or at least check for changes) English only I believe the "proper" way to do this is the use the XML resource files. But I need to make sure the selection references correctly with my data. That is, my app needs to understand that "Poetry" and "Poesía" are the same thing. Is the correct thing to do: Forget about it since I'll never get to the point where I'm translating my app anyway Use a string-array and use the index (0...x) to know what the selection is Use a 2-dimensional string-array with a reference ID in the first column and the text in the second?

  • Random access view in boost::multi_array

    - by linai
    Here is a boost example: typedef boost::multi_array<double, 1> array_type; typedef array_type::index index; array_type A(boost::extents[100]); for(index i = 0; i != A.size(); ++i) { A[i] = (double)i; } // creating view array_type::index_gen indices; typedef boost::multi_array_types::index_range range; array_type::array_view<1>::type myview = A[ indices[range(0,50)] ]; What this code does is creating a subarray or view mapping onto the original array. This view is continuous and covers from 0th to 50th elements of an original array. What if I need to explicitly define elements I'd like to see in the view? How can I create a view with indices like [1, 5, 35, 23] ? Any ideas?

  • Flash content in eLearning: one SWF vs. many?

    - by loucadro
    I am designing a Flash-based language course, and I am not sure which architecture I have to choose. The content won't be uploaded to the Internet, it will be used only locally. Possible architectures: 1) A single SWF with all the data stored internally - it seems a rather clumsy and inefficient way (or it's not?). 2) To make a Flash-based interface, and to keep the data saved in a MySQL database. It presumably allows to organize the content better, avoiding self-repetitions. The problem is that the language teacher (who is not an IT specialist) will have to install additional software to handle MySQL. 3) To make a number of separate SWF files, and to make a simple HTML-file with the index. (and some other solutions I didn't think of) Which is the right architecture, most usable for the teacher and most elegant from the IT point of view?

  • I'm getting a ServerException when I try to send objects from a BlackBerry to a Server via a webserv

    - by DanG
    I'm trying to send an array of objects wrapped in an array object wrapper to a WS via JSR172 WS calls. Using the generated stub, I'm able to download objects from the server, but I'm not able to upload objects to the server. This currently happens on all simulators in house. This is all the information I can get out of the server exception: javax.xml.rpc.JAXRPCException: java.rmi.ServerException: Server cannot handle the message because of some temporary condition. Here are the server specs: Windows 7 IIS 7 or 7.5 .NET 3.5 for the WS code written in C#. If anyone knows how to solve this problem, or knows where to look, I'd love to know. Thanks!

  • Inheritance in kohana

    - by Binaryrespawn
    Hi all, I have recently started to use Kohana and I know inheritance is in infancy stages at the moment. The work around is using a $_has_one annotation on the child class model. In may case i have "page" as the parent of "article". I have something like, protected $_has_one = array('mypage'=>array('model'=>'page', 'foreign_key'=>'id')); In my controller, I have an action which queries the database. In this query I am trying to access fields form the parent of "article" which is the "page". $n->articles=ORM::factory('article')->where('expires','=',0) ->where('articledate','<',date('y-m-d')) ->where('expirydate','>',date('y-m-d')) ->where('mypage->status','=','PUBLISHED') ->order_by('articledate','desc') ->find_all(); The status column resides in the page table and my query is generating an error to the effect of "cannot find status", clearly because it belongs to the parent. Any ideas ?

  • Why is url not registered?(Drupal 6.x)

    - by Andrew
    I'm using hook_menu to register new url so that accessing this url would return some data to ajax function. As title suggested, this url is not registered. How do I know that? I've tried typing this in address bar but, drupal, return main template only rather than the tests string that I created. I'm positive that my module is working for php issues error if I intentionally write wrong syntax. And, yes, I clear cache whenever I make changes. Here's the code - function test_menu() { $my_form['test'] = array( 'title' => 'Test address', 'page callback' => 'test', 'access arguments' => array('access content'), 'type' => MENU_CALLBACK, ); return $my_form; } function test(){ $a= "testing"; return $a; }

  • code-style: Is inline initialization of JS objects ok?

    - by michael
    I often find myself using inline initialization (see example below), especially in a switch statement when I don't know which case loop will hit. I find it easier to read than if statements. But is this good practice or will it incur side-effects or a performance hit? for (var i in array) { var o = o ? o : {}; // init object if it doesn't exist o[array[i]] = 1; // add key-values } Is there a good website to go to get coding style tips?
