  • SVN: Nested repo

    - by Extrakun
    We are working with a PHP application which has no concept of switch-able themes; the situation is that we are modifying the application to add our own features, and CSS/Smarty templates for our own look and feel. We have 2 projects base on this application, each with a different layout/presentation. Hence I need to have one repo for the base application files, and one for the CSS/smarty templates. How should I go about doing this?

  • Setting nested object to null when selected option has empty value

    - by Javi
    Hello, I have a Class which models a User and another which models his country. Something like this: public class User{ private Country country; //other attributes and getter/setters } public class Country{ private Integer id; private String name; //other attributes and getter/setters } I have a Spring form where I have a combobox so the user can select his country or can select the undefined option to indicate he doen't want to provide this information. So I have something like this: <form:select path="country"> <form:option value="">-Select one-</form:option> <form:options items="${countries}" itemLabel="name" itemValue="id"/> </form:select> In my controller I get the autopopulated object with the user information and I want to have country set to null when the "-Select one-" option has been selected. So I have set a initBinder with a custom editor like this: @InitBinder protected void initBinder(WebDataBinder binder) throws ServletException { binder.registerCustomEditor(Country.class, "country", new CustomCountryEditor()); } and my editor do something like this: public class CustomCountryEditor(){ @Override public String getAsText() { //I return the Id of the country } @Override public void setAsText(String str) { //I search in the database for a country with id = new Integer(str) //and set country to that value //or I set country to null in case str == null } } When I submit the form it works because when I have country set to null when I have selected "-Select one-" option or the instance of the country selected. The problem is that when I load the form I have a method like the following one to load the user information. @ModelAttribute("user") public User getUser(){ //loads user from database } The object I get from getUser() has country set to a specific country (not a null value), but in the combobox is not selected any option. I've debugged the application and the CustomCountryEditor works good when setting and getting the text, thoughgetAsText method is called for every item in the list "countries" not only for the "country" field. Any idea? Is there a better way to set null the country object when I select no country option in the combobox? Thanks

  • Convert array to nested HTML list

    - by Frank
    I have a 2 dimensional array. And each value contains a depth. What I want is that the the array is converted to a (unordered) HTML list. I already found a solution in PHP DOMDocument, but I can't really use it since I have to add a lot of classes and content to the HTML. I' have tried to make something myself, but it didn't workout. Here's the array: array ( 0 => array ( 'name' => 'ELECTRONICS', 'depth' => '0', ), 1 => array ( 'name' => 'TELEVISIONS', 'depth' => '1', ), 2 => array ( 'name' => 'TUBE', 'depth' => '2', ), 3 => array ( 'name' => 'LCD', 'depth' => '2', ), 4 => array ( 'name' => 'PLASMA', 'depth' => '2', ), 5 => array ( 'name' => 'PORTABLE ELECTRONICS', 'depth' => '1', ), 6 => array ( 'name' => 'MP3 PLAYERS', 'depth' => '2', ), 7 => array ( 'name' => 'FLASH', 'depth' => '3', ), 8 => array ( 'name' => 'CD PLAYERS', 'depth' => '2', ), 9 => array ( 'name' => '2 WAY RADIOS', 'depth' => '2', ), ) The array has to be converted to a list like this: ELECTRONICS TELEVISIONS TUBE LCD PLASMA PORTABLE ELECTRONICS MP3 PLAYERS FLASH CD PLAYERS 2 WAY RADIOS Thanks in advance, Frank

  • Nested generator functions in python

    - by Yuval A
    Consider a tuple v = (a,b,c) and a generator function generate(x) which receives an item from the tuple and generates several options for each item. What is the pythonic way of generating a set of all the possible combinations of the result of generate(x) on each item in the tuple? I could do this: v = (a,b,c) for d in generate(v[0]): for e in generate(v[1]): for f in generate(v[2]): print d,e,f but that's just ugly, plus I need a generic solution.

  • How to create nested directories in PhoneGap

    - by Stallman
    I have tried on this, but this didn't satisfy my request at all. I write a new one: var file_system; var fs_root; window.requestFileSystem(LocalFileSystem.PERSISTENT, 1024*1024, onInitFs, request_FS_fail); function onInitFs(fs) { file_system= fs; fs_root= file_system.root; alert("ini fs"); create_Directory(); alert("ini fs done."); } var string_array; var main_dir= "story_repository/"+ User_Editime; string_array= new Array("story_repository/",main_dir, main_dir+"/rec", main_dir+"/img","story_repository/"+ User_Name ); function create_Directory(){ var start= 0; var path=""; while(start < string_array.length) { path = string_array[start]; alert(start+" th created directory " +" is "+ path); fs_root.getDirectory ( path , {create: true, exclusive: false}, function(entry) { alert(path +"is created."); }, create_dir_err() ); start++; }//while loop }//create_Directory function create_dir_err() { alert("Recursively create directories error."); } function request_FS_fail() { alert("Failed to request File System "); } Although the directories are created, the it sends me ErrorCallback:"alert("Recursively create directories error.");" Firstly, I don't think this code will work since I have tried on this: This one failed: window.requestFileSystem( LocalFileSystem.PERSISTENT, 0, //request file system success callback. function(fileSys) { fileSys.root.getDirectory( "story_repository/"+ dir_name, {create: true, exclusive: false}, //Create directory story_repository/Stallman_time. function(directory) { alert("Create directory: "+ "story_repository/"+ dir_name); //create dir_name/img/ fileSys.root.getDirectory { "story_repository/"+ dir_name + "/img/", {create: true, exclusive: false}, function(directory) { alert("Create a directory: "+ "story_repository/"+ dir_name + "/img/"); //check. //create dir_name/rec/ fileSys.root.getDirectory { "story_repository/"+ dir_name + "/rec/", {create: true, exclusive: false}, function(directory) { alert("Create a directory: "+ "story_repository/"+ dir_name + "/rec/"); //check. //Go ahead. }, createError } //create dir_name/rec/ }, createError } //create dir_name/img }, createError); }, //Create directory story_repository/Stallman_time. createError()); } I just repeatedly call fs.root.getDirectory only but it failed. But the first one is almost the same... 1. What is the problem at all? Why does the first one always gives me the ErrorCallback? 2. Why can't the second one work? 3. Does anyone has a better solution?(no ErrorcallBack msg) ps: I work on Android and PhoneGap 1.7.0.

    Hi, I am looking for an Open Source & Free Browser based Adhoc / End User Reporting Tool preferably based on Java (any other technologies are also welcome). I have researched on JasperServer Pro, BIRT & Pentaho. Even though these are open source & free, the end user/adhoc reporting components needs to be paid annual license fees which is not quite affordable for us. So please tell you suggestions Thanks In Advance.

  • does the order a composite key is defined matter?

    I have a table with (col1,col2) as a composite primary key. create table twokeytable(col1 int,col2 int,constraint twokeytable_pk primary key (col1,col2)); and another table with col3,col4 collumns witha composite foreign key(col3,col4) which references the(col1,col2) primary key. For some processing I need to drop the foreign key and primary constraints .While restoring the constraints does order of the keys matter?. are these same? create table fktwokeytable(col3 int,col4 int,constraint fkaddfaa_fk foreign key(col4,col3) references twokeytable(col1,col2)) and create table fktwokeytable(col3 int,col4 int,constraint fkaddfaa_fk foreign key(col3,col4) references twokeytable(col1,col2))

  • Wpf binding with nested properties

    - by byte
    ViewModel I have a property of type Member called KeyMember. The 'Member' type has an ObservableCollection called Addresses. The Address is composed of two strings - street and postcode . View I have a ListBox whose item source need to be set to ViewModels's KeyMember property and it should display the Street of all the Past Addresses in the collection. Question My ViewModel and View relationship is established properly. I am able to write a data template for the above simple case as below <ListBox ItemsSource="{Binding KeyMember.Addresses}"> <ListBox.ItemTemplate> <DataTemplate DataType="Address"> <TextBlock Text="{Binding Street}"/> </DataTemplate> </ListBox.ItemTemplate> </ListBox> How would I write the DataTemplate if I change KeyMember from type Member to ObservableCollection< Member assuming that the collection has only one element. PS: I know that for multiple elements in collection, I will have to implement the Master-Detail pattern/scenario.

  • mysql statement with nested SELECT - how to improve performance

    This statement appears inefficient because only one one out of 10 records are selected and only 1 of 100 entries contain comments. What can I do to improve it ? $query = "SELECT A,B,C, (SELECT COUNT(*) FROM comments WHERE comments.nid = header_file.nid) as my_comment_count FROM header_file Where A = 'admin' " edit: I want header records even if no comments are found.

  • Speeding up inner-joins and subqueries while restricting row size and table membership

    - by hiffy
    I'm developing an rss feed reader that uses a bayesian filter to filter out boring blog posts. The Stream table is meant to act as a FIFO buffer from which the webapp will consume 'entries'. I use it to store the temporary relationship between entries, users and bayesian filter classifications. After a user marks an entry as read, it will be added to the metadata table (so that a user isn't presented with material they have already read), and deleted from the stream table. Every three minutes, a background process will repopulate the Stream table with new entries (i.e. whenever the daemon adds new entries after the checks the rss feeds for updates). Problem: The query I came up with is hella slow. More importantly, the Stream table only needs to hold one hundred unread entries at a time; it'll reduce duplication, make processing faster and give me some flexibility with how I display the entries. The query (takes about 9 seconds on 3600 items with no indexes): insert into stream(entry_id, user_id) select entries.id, subscriptions_users.user_id from entries inner join subscriptions_users on subscriptions_users.subscription_id = entries.subscription_id where subscriptions_users.user_id = 1 and entries.id not in (select entry_id from metadata where metadata.user_id = 1) and entries.id not in (select entry_id from stream where user_id = 1); The query explained: insert into stream all of the entries from a user's subscription list (subscriptions_users) that the user has not read (i.e. do not exist in metadata) and which do not already exist in the stream. Attempted solution: adding limit 100 to the end speeds up the query considerably, but upon repeated executions will keep on adding a different set of 100 entries that do not already exist in the table (with each successful query taking longer and longer). This is close but not quite what I wanted to do. Does anyone have any advice (nosql?) or know a more efficient way of composing the query?

  • SQL Complicated Group / Join by Category

    - by Mike Silvis
    I currently have a database structure with two important tables. 1) Food Types (Fruit, Vegetables, Meat) 2) Specific Foods (Apple, Oranges, Carrots, Lettuce, Steak, Pork) I am currently trying to build a SQL statement such that I can have the following. Fruit < Apple, Orange Vegetables < Carrots, Lettuce Meat < Steak, Port I have tried using a statement like the following Select * From Food_Type join (Select * From Foods) as Foods on Food_Type.Type_ID = Foods.Type_ID but this returns every Specific Food, while I only want the first 2 per category. So I basically need my subquery to have a limit statement in it so that it finds only the first 2 per category. However if I simply do the following Select * From Food_Type join (Select * From Foods LIMIT 2) as Foods on Food_Type.Type_ID = Foods.Type_ID My statement only returns 2 results total.

  • how to number t-rows ,when table generated using nested forloop in django templates

    - by stackover
    Hi, This part is from views.py results=[(A,[stuObj1,stuObj2,stuObj3]),(B,[stuObj4,stuObj5,stuObj6]),(C,[stuObj7,stuObj8])] for tup in results: total = tot+len(tup[1]) render_to_response(url,{'results':res , 'total':str(tot),}) this is template code: <th class="name">Name</th> <th class="id">Student ID</th> <th class="grade">Grade</th> {% for tup in results %} {% for student in tup|last %} {% with forloop.parentloop.counter as parentid%} {% with forloop.counter as centerid%} <tbody class="results-body"> <tr> <td>{{student.fname|lower|capfirst}} {{student.lname|lower|capfirst}}</td> <td>{{student.id}}</td> <td>{{tup|first}}</td> </tr> {% endfor %} {% endfor %} Now the problems am having are 1. numbering the rows. Here my problem is am not sure if i can do things like total=total-1 in the templates to get the numbered rows like <td>{{total}}</td> 2.applying css to tr:ever or odd. Whats happening in this case is everytime the loop is running the odd/even ordering is lost. these seems related problems. Any ideas would be great :)

  • Comparing Nested object properties using C#

    - by Kumar
    I have a method which compares two objects and returns a list of all the property names which are different. public static IList<string> GetDifferingProperties(object source, object) { var sourceType = source.GetType(); var sourceProperties = sourceType.GetProperties(); var targetType = target.GetType(); var targetProperties = targetType.GetProperties(); var properties = (from s in sourceProperties from t in targetProperties where s.Name == t.Name && s.PropertyType == t.PropertyType && s.GetValue(source,null) != t.GetValue(target,null) select s.Name).ToList(); return properties; } For example if I have two classes as follows: public class Address { public string AddressLine1 { get; set; } public string AddressLine2 { get; set; } public string City { get; set; } public string State { get; set; } public string Zip { get; set; } } public class Employee { public string FirstName { get; set; } public string MiddleName { get; set; } public string LastName { get; set; } public Address EmployeeAddress { get; set; } } I am trying to compare the following two employee instances: var emp1Address = new Address(); emp1Address.AddressLine1 = "Microsoft Corporation"; emp1Address.AddressLine2 = "One Microsoft Way"; emp1Address.City = "Redmond"; emp1Address.State = "WA"; emp1Address.Zip = "98052-6399"; var emp1 = new Employee(); emp1.FirstName = "Bill"; emp1.LastName = "Gates"; emp1.EmployeeAddress = emp1Address; var emp2Address = new Address(); emp2Address.AddressLine1 = "Gates Foundation"; emp2Address.AddressLine2 = "One Microsoft Way"; emp2Address.City = "Redmond"; emp2Address.State = "WA"; emp2Address.Zip = "98052-6399"; var emp2 = new Employee(); emp2.FirstName = "Melinda"; emp2.LastName = "Gates"; emp2.EmployeeAddress = emp2Address; So when I pass these two employee objects to my GetDifferingProperties method currently it returns FirstName and EmployeeAddress, but it does not tell me which exact property (which in this case is Address1) in the EmployeeAddress has changed. How can I tweak this method to get something like EmployeeAddress.Address1?

  • Select those objects whose related objects IDs are *all* in given string

    - by Jannis
    Hi Django people, I want to build a frontend to a recipe database which enables the user to search for a list of recipes which are cookable with the ingredients the user supplies. I have the following models class Ingredient(models.Model): name = models.CharField(max_length=100, unique=True) slug = models.SlugField(max_length=100, unique=True) importancy = models.PositiveSmallIntegerField(default=4) […] class Amount(models.Model): recipe = models.ForeignKey('Recipe') ingredient = models.ForeignKey(Ingredient) […] class Rezept(models.Model): name = models.CharField(max_length=100) slug = models.SlugField() instructions = models.TextField() ingredients = models.ManyToManyField(Ingredient, through=Amount) […] and a rawquery which does exactly what I want: It gets all the recipes whose required ingredients are all contained in the list of strings that the user supplies. If he supplies more than necessary, it's fine too. query = "SELECT *, COUNT(amount.zutat_id) AS selected_count_ingredients, (SELECT COUNT(*) FROM amount WHERE amount.recipe_id = amount.id) AS count_ingredients FROM amount LEFT OUTER JOIN amount ON (recipe.id = recipe.recipe_id) WHERE amount.ingredient_id IN (%s) GROUP BY amount.id HAVING count_ingredient=selected_count_ingredient" % ",".join([str(ingredient.id) for ingredient in ingredients]) rezepte = Rezept.objects.raw(query) Now, what I'm looking for is a way that does not rely on .raw() as I would like to do it purely with Django's queryset methods. Additionally, it would be awesome if you guys knew a way of including the ingredient's importancy in the lookup so that a recipe is still shown as a result even though one of its ingredients (that has an importancy of 0) is not supplied by the user.

  • Parse Nested XML tags with the same name

    - by footose
    Let's take a simple XML document: <x> <e> <e> <e>Whatever 1</e> </e> </e> <e> <e> <e>Whatever 2</e> </e> </e> <e> <e> <e>Whatever 3</e> </e> </e> </x> Using the standard org.w3c.dom, I can get the nodes in X by doing.. NodeList fullnodelist = doc.getElementsByTagName("x"); But if I want to return the next set of "e" I try to use something like .. Element element = (Element) fullnodelist.item(0); NodeList nodes = pelement.getElementsByTagName("e"); Expecting it to return "3" nodes (because there are 3 sets of "e"), but instead, it returns "9" - becuase it gets all entries with "e" apperently. This would be fine in the above case, because I could probably iterate through and find what I'm looking for. The problem I'm having is that when the XML file looks like the following: <x> <e> <pattern>whatever</pattern> <blanks> <e>Something Else</e> </blanks> </e> <e> <pattern>whatever</pattern> <blanks> <e>Something Else</e> </blanks> </e> </x> When I request the "e" value, it returns 4, instead of (what i expect) 2. Am I just not understanding how the DOM parsing works? Typically in the past I have used my own XML documents so I would never name the items like this, but unfortunately this is not my XML file and I have no choice to work like this. What I thought I would do is write a loop that "drills down" nodes so that I could group each node together... public static NodeList getNodeList(Element pelement, String find) { String[] nodesfind = Utilities.Split(find, "/"); NodeList nodeList = null; for (int i = 0 ; i <= nodesfind.length - 1; i++ ) { nodeList = pelement.getElementsByTagName( nodesfind[i] ); pelement = (Element)nodeList.item(i); } // value of the nod we are looking for return nodeList; } .. So that if you passed "s/e" into the function, it would return the 2 nodes that I'm looking for (or elements, maybe I'm using the terminology incorrect?). instead it returns all of the "e" nodes within that node. I'm using J2SE for this, so options are rather limited. I can't use any third party XML Parsers. Anyway, if anyone is still with me and has a suggestion, it would be appreciated.

  • iPhone SDK Nested For Loop performance

    - by Skeep
    Hi All, I have a NSArray of string id and a NSDictionary of NSDictionary objects. I am currently looping through the string id array to match the id value in the NSDictionary. There are around 200 NSDictionary objects and only 5 or so string ID. My current code is such: for (NSString *Str in aArr) { for (NSDictionary *a in apArr) { if ([a objectForKey:@"id"] == Str) { NSLog(@"Found!"); } } } The performance of the above code is really slow and I was wondering if there is a better way to do this?

  • Pass deeply nested element to function in JQuery

    I have this form: <form action="contact.php" method="post" id="contactform"> <ol> <li> <label for="name">First Name * </label> <input id="name" name="name" class="text" /> </li> <li> <label for="email">Your email * </label> <input id="email" name="email" class="text" /> </li> <li> <label for="company">Company</label> <input id="company" name="company" class="text" /> </li> <li> <label for="subject">Subject</label> <input id="subject" name="subject" class="text" /> </li> <li> <label for="message">Message * </label> <textarea id="message" name="message" rows="6" cols="50"></textarea> </li> <li class="buttons"> <input type="image" name="imageField" id="imageField" src="images/send.gif" /> </li> </ol> </form> This javascript function that does some basic validation: function validateRequired(field,alerttxt) { with (field) { if (value==null||value=="") { alert(alerttxt); return false; } return true; } } And this script (written with jquery) to intercept the submit event jQuery(document).ready(function(){ $('#contactform').submit(function(){ ... }); }); The problem is that, inside the last script I want to call validateRequired passing each required input/textarea (namely: name, email and message) as first parameter. I tried like this: validateRequired($('#name')); but it doesn't work. How can I do this?

  • accessing a value of a nested hash

    - by st
    Hello! I am new to perl and I have a problem that's very simple but I cannot find the answer when consulting my perl book. When printing the result of Dumper($request); I get the following result: $VAR1 = bless( { '_protocol' => 'HTTP/1.1', '_content' => '', '_uri' => bless( do{\(my $o = 'http://myawesomeserver.org:8081/counter/')}, 'URI::http' ), '_headers' => bless( { 'user-agent' => 'Mozilla/5.0 (X11; U; Linux i686; en; rv:1.9.0.4) Gecko/20080528 Epiphany/2.22 Firefox/3.0', 'connection' => 'keep-alive', 'cache-control' => 'max-age=0', 'keep-alive' => '300', 'accept' => 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8', 'accept-language' => 'en-us,en;q=0.5', 'accept-encoding' => 'gzip,deflate', 'host' => 'localhost:8081', 'accept-charset' => 'ISO-8859-1,utf-8;q=0.7,*;q=0.7' }, 'HTTP::Headers' ), '_method' => 'GET', '_handle' => bless( \*Symbol::GEN0, 'FileHandle' ) }, 'HTTP::Server::Simple::Dispatched::Request' ); How can I access the values of '_method' ('GET') or of 'host' ('localhost:8081'). I know that's an easy question, but perl is somewhat cryptic at the beginning. Thank you, St.
