• How to "defragment" MongoDB index effectively in production?

  - by dfrankow

  I've been looking at MongoDB. Feels good. I added some indexes to a collection, uploaded a bunch of data, then removed all the data, and I noticed the indexes did not change size, similar to the behavior reported here. If I call db.repairDatabase() the indexes are then squashed to near-zero. Similarly if I don't remove all the data, but call repairDatabase(), the indexes are squashed somewhat (perhaps because unused extends are truncated?). I am getting index size from "totalIndexSize" of db.collection.stats(). However, that takes a long time (I've read it could be hours on a large database). It's unclear to me how available the database is for reads or writes while it is running. I am guessing not so available. Since I want to run as few instances of mongod as possible, I want to understand more about how indexes are managed after deletes. Can anyone point me to anything or give any advice?

• Rails does not display error messages on a form in a custom method

  - by slythic

  Hi all, I've created a custom method called checkout in my app. I create an order (which is done my adding products to my "cart"), assign it to my client, and then I head to my checkout screen where I confirm the items and enter their customer order number and complete the order (submit). Everything works great except that it doesn't display error messages. I'm able to display a flash error notice (seen in complete_order method) when things go wrong but it doesn't specify the details like a normal form would. The error messages should appear if the customer order number is not unique for that client. Below is the custom method (checkout) related code. Order Model: validates_uniqueness_of :customer_order_number, :scope => :client_id Orders_controller: def checkout @order = current_order end def complete_order @order = current_order respond_to do |format| if @order.update_attributes(params[:order]) @order.complete #sets submitted datetime and state to 'complete' flash[:notice] = 'Thank you! Your order is being processed.' format.html { redirect_to( products_path ) } format.xml { head :ok } else flash[:error] = 'Please review your items' #added to confirm an error is present format.html { redirect_to( checkout_path ) } format.xml { render :xml => @order.errors, :status => :unprocessable_entity } end end end And the form in the checkout view: <% form_for @order, :url => { :controller => "orders", :action => "complete_order" } do |f| %> <%= f.error_messages %> <%= f.text_field :customer_order_number, :label => "Purchase Order Number" %> <p> <%= f.submit 'Complete Order', :confirm => 'Are you sure?' %> <small> or <%= link_to 'cancel', current_cart_path %></small> </p> <% end %> Any idea how I can display the specific error messages? Thank you in advance! -Tony

• navigator.onLine

  - by cf_PhillipSenn

  I'm playing with the incomplete example found at http://www.w3.org/TR/offline-webapps/ But I'm distressed to see comments in it like: "renders the note somewhere", and "report error", and "// …" So, will someone please help me write a valid example? Here's what I've got so far: <!DOCTYPE HTML> <html manifest="cache-manifest"> <head> <script> var db = openDatabase("notes", "", "The Example Notes App!", 1048576); function renderNote(row) { // renders the note somewhere } function reportError(source, message) { // report error } function renderNotes() { db.transaction(function(tx) { tx.executeSql('CREATE TABLE IF NOT EXISTS Notes(title TEXT, body TEXT)', []); tx.executeSql(‘SELECT * FROM Notes’, [], function(tx, rs) { for(var i = 0; i < rs.rows.length; i++) { renderNote(rs.rows[i]); } }); }); } function insertNote(title, text) { db.transaction(function(tx) { tx.executeSql('INSERT INTO Notes VALUES(?, ?)', [ title, text ], function(tx, rs) { // … }, function(tx, error) { reportError('sql', error.message); }); }); } </script> <style> label { display:block; } </style> </head> <body> <form> <label for="mytitle">Title:</label> <input name="mytitle"> <label for="mytext">Text:</label> <textarea name="mytext"></textarea> <!-- There is no submit button because I want to save the info on every keystroke --> </form> </body> </html> I also know that I have to incorporate this in there somewhere: if (navigator.onLine) { // Send data using XMLHttpRequest } else { // Queue data locally to send later } But I'm not sure what even I would tie that too.

• sync framework server to server synchronization

  - by nihi_l_ist

  I have kind of a such scenario: Here i need to synchronize local server database with main DB server(example: computers in office are connected to office server and they use it like a local server, so that no sync is required.BUT computers in other office work with their local server too and we need synchronization between the offices though the main DB server.). As i see i cant use SQLCompact here. Is there a provider to do the server-to-server synchronization right from the client? If no can someone provide a sample of solution of how to manage such situation?

• Removing a result from Queryset

  - by Enrico

  Is there a simple way to discard/remove the last result in a queryset without affecting the db? I am trying to paginate results in Django, but don't know the total number of objects for a given query. I was planning on using next/previous or older/newer links, so I only need to know if this is the first and/or last page. First is easy to check. To check for the last page I can compare the number of results with the pagesize or make a second query. The first method fails to detect the last page when the number of results in the last set equals the pagesize (ie 100 records get broken into 10 pages with the last page containing exactly 10 results) and I would like to avoid making a second query. My current thought is that I should fetch pagesize + 1 results from the db. If the queryset length equals 11, I know this is not the last page and I want to discard the last result in the queryset before passing the queryset to the template.

• Class 'org.springframework.http.converter.ResourceHttpMessageConverter' not found - how to correct?

  - by Ash Kim

  Eclipse STS is reporting I have problem with my spring project. It's a fresh project generated from the Spring Web MVC Project Template (File-New-Spring Template Project-Spring Web MVC ). When I create the project it has no problems - it's only once I modify the pom (by adding the hibernate dependencies) that STS then picks up the spring problem. Strangely if I revert the pom the problem remains. Also I can run the project on a spring tc server and all works correctly. Any ideas how I can satisfy this problem report?

• Get tag name and value of a given node using XMLReader, DOM, Xpath

  - by rossjha

  I need to query an xml document and then display specific tag values, e.g. forename, surname, group(dept), job_title. I'm using XMLReader as i may need to work with large XML files. I using DomXPath to filter the data, but i don't know how to retrieve the nodeName and value for each element. The code below only returns 'member' as the node name? Any help would be appreciated. <?php $reader = new XMLReader(); $reader->open('include/staff.xml'); while ($reader->read()){ switch($reader->nodeType){ case(XMLREADER::ELEMENT): if($reader->localName === 'staff'){ $node = $reader->expand(); $dom = new DomDocument(); $dom->formatOutput = true; $n = $dom->importNode($node, true); $dom->appendChild($n); $xp = new DomXpath($dom); $res = $xp->query("/staff/member[groups='HR']"); } } } echo $res->item(0)->nodeName; echo $res->item(0)->nodeValue; ?>

• Using a table-alias in Kohana queries?

  - by Aristotle

  I'm trying to run a simple query with $this->db in Kohana, but am running into some syntax issues when I try to use an alias for a table within my query: $result = $this->db ->select("ci.chapter_id, ci.book_id, ci.chapter_heading, ci.chapter_number") ->from("chapter_info ci") ->where(array("ci.chapter_number" => $chapter, "ci.book_id" => $book)) ->get(); It seems to me that this should work just fine. I'm stating that "chapter_info" ought to be known as "ci," yet this isn't taking for some reason. The error is pretty straight-forward: There was an SQL error: Table 'gb_data.chapter_info ci' doesn't exist - SELECT `ci`.`chapter_id`, `ci`.`book_id`, `ci`.`chapter_heading`, `ci`.`chapter_number` FROM (`chapter_info ci`) WHERE `ci`.`chapter_number` = 1 AND `ci`.`book_id` = 1 If I use the full table name, rather than an alias, I get the expected results without error. This requires me to write much more verbose queries, which isn't ideal. Is there some way to use shorter names for tables within Kohana's query-builder?

• Fluent NHibernate SchemaExport to SQLite not pluralizing Table Names

  - by weenet

  I am using SQLite as my db during development, and I want to postpone actually creating a final database until my domains are fully mapped. So I have this in my Global.asax.cs file: private void InitializeNHibernateSession() { Configuration cfg = NHibernateSession.Init( webSessionStorage, new [] { Server.MapPath("~/bin/MyNamespace.Data.dll") }, new AutoPersistenceModelGenerator().Generate(), Server.MapPath("~/NHibernate.config")); if (ConfigurationManager.AppSettings["DbGen"] == "true") { var export = new SchemaExport(cfg); export.Execute(true, true, false, NHibernateSession.Current.Connection, File.CreateText(@"DDL.sql")); } } The AutoPersistenceModelGenerator hooks up the various conventions, including a TableNameConvention like so: public void Apply(FluentNHibernate.Conventions.Instances.IClassInstance instance) { instance.Table(Inflector.Net.Inflector.Pluralize(instance.EntityType.Name)); } This is working nicely execpt that the sqlite db generated does not have pluralized table names. Any idea what I'm missing? Thanks.

• Prepare and import data into existing database

  - by Álvaro G. Vicario

  I maintain a PHP application with SQL Server backend. The DB structure is roughly this: lot === lot_id (pk, identify) lot_code building ======== buildin_id (pk, identity) lot_id (fk) inspection ========== inspection_id (pk, identify) building_id (fk) date inspector result The database already has lots and buildings and I need to import some inspections. Key points are: It's a one-time initial load. Data comes in an Excel file.

• bing search api ajax does not work

  - by jhon

  Hi guys, I want to use the Bing's search api with javascript. Actually, I want the user to write something and query Bing in order to get just images. so, I tried it using ajax. If I try the url http://api.search.live.net/xml.aspx?Appid=[YOURAPIKEY]&sources=image&query=home directly (with the browser) I do get an xml document. but if I use XMLHttpRequest it does not work. <html> <body> <script> var xhr = new XMLHttpRequest(); var url="http://api.search.live.net/xml.aspx?Appid=[YOURAPIKEY]&sources=image&query=home" xhr.open("GET", url, true ); xhr.onreadystatechange=function(){ /*if( xhr.readyState == 4 && xhr.status == 200) { document.write( xhr.responseText ); }*/ alert( xhr.readyState +" "+xhr.status +xhr.statusText +xhr); }; xhr.send(null); </script> </body> </html> Questions: 1) why does the code from above does not work? 2) any other way to do this without XMLHttpRequest? thanks. btw. I'm just interested in fix this for Firefox and without external libraries (jquery and so on).

• Drill through table does not show correct count when used with a dimension having parent child hiera

  - by Arun Singhal

  Hi All, I have a dimension with parent child hierarchy as shown in code block. The issue i am facing is if i have a filter on parent child dimension then drill through table does not show filtered data instead it shows all the data for that dimension. Here is an example. <Dimension type="StandardDimension" name="page_type_d" caption="Page Type"> <Hierarchy name="page_type_h" hasAll="true" allMemberName="all_page_types" allMemberCaption="All Page Types" primaryKey="id"> <Table name="npg_page_type_view" alias="pt"> </Table> <Level name="Page Type" column="id" nameColumn="display_name" parentColumn="parent_id" nullParentValue="0" type="Integer" uniqueMembers="true" levelType="Regular" hideMemberIf="Never" caption="Page Type"> <Closure parentColumn="parent_id" childColumn="page_type_id"> <Table name="dim_page_types_closure"> </Table> </Closure> </Level> </Hierarchy> Now suppose i have 4 rows in npg_page_type_view table id display_name parent_id 19 HTML 100 20 PDF 100 21 XML 0 100 Total 0 Now suppose in my fact table i have following records id count 19 2 20 3 21 1 Following is my analysis view. Total (HTML and PDF) - 5 HTML - 2 PDF - 3 XML - 1 Now if i add filter(say Total) on this analysis view using OLAP cube. Then my analysis view shows the following. Total (HTML and PDF) - 5 Upto this point everything works fine. Now if i click on 5 (to view drill through table) It shows me data against all page type i.e. HTML, PDF, XML but as per filter it should show only HTML and PDF. Is it an exciting issue or am i doing something wrong here? Please help me.

• flex actionscript Datagridcolumn array

  - by Jad

  Hi, We have an AIR app and using a datagrid. We want to store the dataGrid.columns array in mySQL DB through PHP. This is needed because the user can customise the column headers of the datagrid and his preference needs to be stored and shown to him on his next login. Using HTTPService, we tried sending the dataGrid.columns array as a string, as follows, var ht:HTTPService = new HTTPService(); ht.url = Config.getServerURL(); ht.method = URLRequestMethod.POST; ht.resultFormat = "text"; ht.request["action"] = "updateGrid"; ht.request["headercolumns"] = colsArray.toString(); The data is stord as comma separated array string in DB. When we retrieve it back, cannot seem to cast it back to the DatagridColumns and assign it. Please let me know. Regards Jada.

• suggestions for declarative GUI programming in Java

  - by Jason S

  I wonder if there are any suggestions for declarative GUI programming in Java. (I abhor visual-based GUI creator/editor software, but am getting a little tired of manually instantiating JPanels and Boxes and JLabels and JLists etc.) That's my overall question, but I have two specific questions for approaches I'm thinking of taking: JavaFX: is there an example somewhere of a realistic GUI display (e.g. not circles and rectangles, but listboxes and buttons and labels and the like) in JavaFX, which can interface with a Java sourcefile that accesses and updates various elements? Plain Old Swing with something to parse XUL-ish XML: has anyone invented a declarative syntax (like XUL) for XML for use with Java Swing? I suppose it wouldn't be hard to do, to create some code based on STaX which reads an XML file, instantiates a hierarchy of Swing elements, and makes the hierarchy accessible through some kind of object model. But I'd rather use something that's well-known and documented and tested than to try to invent such a thing myself. JGoodies Forms -- not exactly declarative, but kinda close & I've had good luck with JGoodies Binding. But their syntax for Form Layout seems kinda cryptic. edit: lots of great answers here! (& I added #3 above) I'd be especially grateful for hearing any experiences any of you have had with using one of these frameworks for real-world applications. p.s. I did try a few google searches ("java gui declarative"), just didn't quite know what to look for.

• ASP.NET cached aspx page & IIS logs

  - by Vishal Seth

  Hi guys, Is there any way to find out if ASP.Net runtime has served a cached copy of ASPX page or actually went through the page life cycle? Here is my problem: I'm seeing many entries in my IIS log files that were served successfully (200 OK). I've a corresponding logging code (Log4Net API) in the Session_Start and Application_BeginRequest() events that is logging every request to my DB with more details. I'm not seeing any corresponding entries in my SQL DB for some cases that should have been created by Log4Net code. Are there any logs available to find out if a cached copy was served by .NET worker process? Moreover, if my logging code would throw an exception, won't that show up as 500 in IIS logs? The code is on Windows 2008 Server, IIS 7.

• Please suggest some alternative to Drupal

  - by abovesun

  Drupal propose completely different approach in web development (comparing with RoR like frameworks) and it is extremely good from development speed perspective. For example, it is quite easy to clone 90% of stackoverflow functionality using Drupal. But it has several big drawbacks: it is f''cking slow (100-400 requests per page) db structure very complicated, need at least 2 tables for easy content (entity) type, CCK fields very easy generate tons of new db tables anti-object oriented, rather aspect-oriented bad "view" layer implementation, no strange forward layouts and so on. After all this items I can say I like Drupal, but I would like something same, but more elegant and more object oriented. Probably something like http://drupy.net/ - drupal emulation on the top of django. P.S. I wrote this question not for new holy word flame, just write if you know alternative that uses something similar approach.

• Dynamic data validation in ASP.NET MVC

  - by user252160

  I've recently read about the model validation capabilities of ASP.NET MVC which are all very cool until a certain point. What happens if the application doesn't know the data that it works with because it is all stored in DB and built together at runtime. Just like in Drupal, I'd like to be able to define custom types at runtime, and assign runtime validation rules as well. Obviously, the idea of assigning attributes to well established models is now gone. What else could be done ? I am thinking in terms of rules being stored as JSON objects in the DB fields or something like that.

• trying to use ActiveRecord with Sinatra, Migration fails question

• 'Stack level too deep' error in engine-like plugin with globalize

  - by nutsmuggler

  Hello folks. I have built an engine-like plugin thanks to the new features of Rails 2.3. It's a 'Product' module for a CMS, extrapolated from a previously existing (and working) model/controller. The plugin relies on easy_fckeditor and on globalize (description and title field are localised), and I suspect that globalized could be the culprit here... Everything works fine, except for the update action. I get the following error message: (posting just the first lines, all the message is about attribute_methods) stack level too deep /Library/Ruby/Gems/1.8/gems/activerecord-2.3.2/lib/active_record/attribute_methods.rb:64:in `generated_methods?' /Library/Ruby/Gems/1.8/gems/activerecord-2.3.2/lib/active_record/attribute_methods.rb:241:in `method_missing' /Library/Ruby/Gems/1.8/gems/activerecord-2.3.2/lib/active_record/attribute_methods.rb:249:in `method_missing' For referenze, the full error stack is here: http://pastie.org/596546 I've tried to debug eliminating all the input fields, one by one, but I keep getting the error. fckeditor doesn't seem the culprit (error even without fckeditor) This is the action: def update params[:product][:term_ids] ||= [] @product = Product.find(params[:id]) respond_to do |format| if @product.update_attributes(params[:product]) flash[:notice] = t(:Product_was_successfully_updated) format.html { redirect_to products_path } format.xml { head :ok } else format.html { render :action => "edit" } format.xml { render :xml => @product.errors, :status => :unprocessable_entity } end end end As you see it's quite straightforward. Of course I am not hoping someone to solve this question straightaway, I'd just like to have a head up, a suggestion about where to look to solve this issue. Thanks in advance, Davide

• SQL efficiency argument, add a column or solvable by query?

  - by theTurk

  I am a recent college graduate and a new hire for software development. Things have been a little slow lately so I was given a db task. My db skills are limited to pet projects with Rails and Django. So, I was a little surprised with my latest task. I have been asked by my manager to subclass Person with a 'Parent' table and add a reference to their custodian in the Person table. This is to facilitate going from Parent to Form when the custodian, not the Parent, is the FormContact. Here is a simplified, mock structure of a sql-db I am working with. I would have drawn the relationship tables if I had access to Visio. We have a table 'Person' and we have a table 'Form'. There is a table, 'FormContact', that relates a Person to a Form, not all Persons are related to a Form. There is a relationship table for Person to Person relationships (Employer, Parent, etc.) I've asked, "Why this couldn't be handled by a query?" Response, Inefficient. (Really!?!) So, I ask, "Why not have a reference to the Form? That would be more efficient since you wouldn't be querying the FormContacts table with the reference from child/custodian." Response, this would essentially make the Parent is a FormContact. (Fair enough.) I went ahead an wrote a query to get from non-FormContact Parent to Form, and tested on the production server. The response time was instantaneous. *SOME_VALUE* is the Parent's fk ID. SELECT FormID FROM FormContact WHERE FormContact.ContactID IN (SELECT SourceContactID FROM ContactRelationship WHERE (ContactRelationship.RelatedContactID = *SOME_VALUE*) AND (ContactRelationship.Relationship = 'Parent')); If I am right, "This is an unnecessary change." What should I do, defend my position or should I concede to the managers request? If I am wrong. What is my error? Is there a better solution than the manager's?

• Read attributes of MSBuild custom tasks via events in the Logger

  - by gt

  I am trying to write a MSBuild logger module which logs information when receiving TaskStarted events about the Task and its parameters. The build is run with the command: MSBuild.exe /logger:MyLogger.dll build.xml Within the build.xml is a sequence of tasks, most of which have been custom written to compile a (C++ or C#) solution, and are accessed with the following custom Task: <DoCompile Desc="Building MyProject 1" Param1="$(Param1Value)" /> <DoCompile Desc="Building MyProject 2" Param1="$(Param1Value)" /> <!-- etc --> The custom build task DoCompile is defined as: public class DoCompile : Microsoft.Build.Utilities.Task { [Required] public string Description { set { _description = value; } } // ... more code here ... } Whilst the build is running, as each task starts, the logger module receives IEventSource.TaskStarted events, subscribed to as follows: public class MyLogger : Microsoft.Build.Utilities.Logger { public override void Initialize(Microsoft.Build.Framework.IEventSource eventSource) { eventSource.TaskStarted += taskStarted; } private void taskStarted(object sender, Microsoft.Build.Framework.TaskStartedEventArgs e) { // write e.TaskName, attributes and e.Timestamp to log file } } The problem I have is that in the taskStarted() method above, I want to be able to access the attributes of the task for which the event was fired. I only have access to the logger code and cannot change either the build.xml or the custom build tasks. Can anyone suggest a way I can do this?
