• Can I Do a Foreach on a TimeSpan by Timespan Type?

  - by IPX Ares

  I have a requirement that regardless of the start and dates that I need to loop through that timespan and calculate figures at the month level. I cannot seem to figure it out, and maybe it is not possible, but I would like to do something like: FOREACH Month As TimeSpan in ContractRange.Months Do Calculations (Month.Start, Month.End) NEXT Is this possible or do I need to calculate the number of months, and just iterate through the amount of months and calculate the start/end of that month based on my index?

• Postgresql count+sort performance

  - by invictus

  I have built a small inventory system using postgresql and psycopg2. Everything works great, except, when I want to create aggregated summaries/reports of the content, I get really bad performance due to count()'ing and sorting. The DB schema is as follows: CREATE TABLE hosts ( id SERIAL PRIMARY KEY, name VARCHAR(255) ); CREATE TABLE items ( id SERIAL PRIMARY KEY, description TEXT ); CREATE TABLE host_item ( id SERIAL PRIMARY KEY, host INTEGER REFERENCES hosts(id) ON DELETE CASCADE ON UPDATE CASCADE, item INTEGER REFERENCES items(id) ON DELETE CASCADE ON UPDATE CASCADE ); There are some other fields as well, but those are not relevant. I want to extract 2 different reports: - List of all hosts with the number of items per, ordered from highest to lowest count - List of all items with the number of hosts per, ordered from highest to lowest count I have used 2 queries for the purpose: Items with host count: SELECT i.id, i.description, COUNT(hi.id) AS count FROM items AS i LEFT JOIN host_item AS hi ON (i.id=hi.item) GROUP BY i.id ORDER BY count DESC LIMIT 10; Hosts with item count: SELECT h.id, h.name, COUNT(hi.id) AS count FROM hosts AS h LEFT JOIN host_item AS hi ON (h.id=hi.host) GROUP BY h.id ORDER BY count DESC LIMIT 10; Problem is: the queries runs for 5-6 seconds before returning any data. As this is a web based application, 6 seconds are just not acceptable. The database is heavily populated with approximately 50k hosts, 1000 items and 400 000 host/items relations, and will likely increase significantly when (or perhaps if) the application will be used. After playing around, I found that by removing the "ORDER BY count DESC" part, both queries would execute instantly without any delay whatsoever (less than 20ms to finish the queries). Is there any way I can optimize these queries so that I can get the result sorted without the delay? I was trying different indexes, but seeing as the count is computed it is possible to utilize an index for this. I have read that count()'ing in postgresql is slow, but its the sorting that are causing me problems... My current workaround is to run the queries above as an hourly job, putting the result into a new table with an index on the count column for quick lookup. I use Postgresql 9.2.

• How to perform add/update of a model object that contains EntitySet

  - by David Liddle

  I have a similar concept to the SO questions/tags scenario however am trying to decide the best way of implementation. Tables Questions, QuestionTags and Tags Questions QuestionTags Tags --------- ------------ ---- QID QID TID QName TID TName When adding/updating a question I have 2 textboxes. The important part is a single textbox that allows users to enter in multiple Tags separated by spaces. I am using Linq2Sql so the Questions model has an EntitySet of QuestionTags with then link to Tags. My question is regarding the adding/updating of Questions (part 1), and also how to best show QuestionTags for a Question (part 2). Part 1 Before performing an add/update, my service layer needs to deal with 3 scenarios before passing to their respective repositories. Insert Tags that do not already exist Insert/Update Question Insert QuestionTags - when updating need to remove existing QuestionTags Here is my code below however started to get into a bit of a muddle. I've created extension methods on my repositories to get Tags WithNames etc. public void Add(Question q, string tags) { var tagList = tags.Split(new string[] { " " }, StringSplitOptions.RemoveEmptyEntries).ToList(); using (DB.TransactionScope ts = new DB.TransactionScope()) { var existingTags = TagsRepository.Get() .WithName(tagList) .ToList(); var newTags = (from t in tagList select new Tag { TName = t }).Except(existingTags, new TagsComparer()).ToList(); TagsRepository.Add(newTags); //need to insert QuestionTags QuestionsRepository.Add(q); ts.Complete(); } } Part 2 My second question is, when displaying a list of Questions how is it best to show their QuestionTags? For example, I have an Index view that shows a list of Questions in a table. One of the columns shows an image and when the user hovers over it shows the list of Tags. My current implementation is to create a custom ViewModel and show a List of QuestionIndexViewModel in the View. QuestionIndexViewModel { Question Question { get; set; } string Tags { get; set; } } However, this seems a bit clumsy and quite a few DB calls. public ViewResult Index() { var model= new List<QuestionIndexViewModel>(); //make a call to get a list of questions //foreach question make a call to get their QuestionTags, //to be able to get their Tag names and then join them //to form a single string. return View(model); } Also, just for test purposes using SQL Profiler, I decided to iterate through the QuestionTags entity set of a Question in my ViewModel however nothing was picked up in Profiler? What would be the reason for this?

• How to add new object to an IList mapped as a one-to-many with NHibernate?

  - by Jørn Schou-Rode

  My model contains a class Section which has an ordered list of Statics that are part of this section. Leaving all the other properties out, the implementation of the model looks like this: public class Section { public virtual int Id { get; private set; } public virtual IList<Static> Statics { get; private set; } } public class Static { public virtual int Id { get; private set; } } In the database, the relationship is implemented as a one-to-many, where the table Static has a foreign key pointing to Section and an integer column Position to store its index position in the list it is part of. The mapping is done in Fluent NHibernate like this: public SectionMap() { Id(x => x.Id); HasMany(x => x.Statics).Cascade.All().LazyLoad() .AsList(x => x.WithColumn("Position")); } public StaticMap() { Id(x => x.Id); References(x => x.Section); } Now I am able to load existing Statics, and I am also able to update the details of those. However, I cannot seem to find a way to add new Statics to a Section, and have this change persisted to the database. I have tried several combinations of: mySection.Statics.Add(myStatic) session.Update(mySection) session.Save(myStatic) but the closest I have gotten (using the first two statements), is to an SQL exception reading: "Cannot insert the value NULL into column 'Position'". Clearly an INSERT is attempted here, but NHibernate does not seem to automatically append the index position to the SQL statement. What am I doing wrong? Am I missing something in my mappings? Do I need to expose the Position column as a property and assign a value to it myself? EDIT: Apparently everything works as expected, if I remove the NOT NULL constraint on the Static.Position column in the database. I guess NHibernate makes the insert and immediatly after updates the row with a Position value. While this is an anwers to the question, I am not sure if it is the best one. I would prefer the Position column to be not nullable, so I still hope there is some way to make NHibernate provide a value for that column directly in the INSERT statement. Thus, the question is still open. Any other solutions?

• JQuery Datepicker Date highlight Issue

  - by Isola Olufemi

  I have an in-line date picker in which I want to highlight some dates based on array of strings from the server side. I found out the on load of the page with the datepicker, events the matches in the current month will not be highlighted. when I click the next month button the events on the next moth will be highlighted. What I discovered that i the matching only get highlighted when I click to the next month and not when I click back to the previous month. Below is my script: var actionCalDates = new Array(); function getDates(month, year) { $.ajax({ url: "/Index/GetAllAlerts", data: { month: month, year: year }, success: function (result) { var date = new Date(); var i = new Number(date.getMonth()); i += 1; actionCalDates = result.split(","); } }); } function getTitle(ar, d) { var result = ""; for (var i = 0; i < ar.length; i++) { if (ar[i].indexOf(d) != -1) { var e = actionCalDates[i].split(";"); result += e[0] + "\n"; } } return result; } $('#calendar').datepicker({ numberOfMonths: [1, 1], showCurrentAtPos: 0, dateFormat: 'dd/mm/y', beforeShowDay: function (thedate) { var theday = thedate.getDate(); var x = new Number(thedate.getMonth()); x += 1; var date = thedate.getDate() + "/" + x + "/" + thedate.getFullYear(); getDates(x, thedate.getFullYear()); for (var i = 0; i < actionCalDates.length; i++) { var entry = actionCalDates[i].split(";"); if (date == entry[1]) { return [true, "highlight", getTitle(actionCalDates, date)]; } } return [true, "", ""]; }, onChangeMonthYear: function (year, month, inst) { getDates(month, year); }, onSelect: function (d, instance) { $.ajax({ url: '/Index/AlertConvertDate', datatype: 'text', data: { dateString: d }, error: function (xhr, ajaxOptions, thrownError) { alert(xhr.statusText); alert(thrownError); }, success: function (data) { window.SetHomeContent(data); } }); } }); Please can someone point out where I went wrong? Thank you all.

• Wordpress pages address rewrite

  - by kemp

  UPDATE I tried using the internal wordpress rewrite. What I have to do is an address like this: http://example.com/galleria/artist-name sent to the gallery.php page with a variable containing the artist-name. I used these rules as per Wordpress' documentation: // REWRITE RULES (per gallery) {{{ add_filter('rewrite_rules_array','wp_insertMyRewriteRules'); add_filter('query_vars','wp_insertMyRewriteQueryVars'); add_filter('init','flushRules'); // Remember to flush_rules() when adding rules function flushRules(){ global $wp_rewrite; $wp_rewrite->flush_rules(); } // Adding a new rule function wp_insertMyRewriteRules($rules) { $newrules = array(); $newrules['(galleria)/(.*)$'] = 'index.php?pagename=gallery&galleryname=$matches[2]'; return $newrules + $rules; } // Adding the id var so that WP recognizes it function wp_insertMyRewriteQueryVars($vars) { array_push($vars, 'galleryname'); return $vars; } what's weird now is that on my local wordpress test install, that works fine: the gallery page is called and the galleryname variable is passed. On the real site, on the other hand, the initial URL is accepted (as in it doesn't go into a 404) BUT it changes to http://example.com/gallery (I mean it actually changes in the browser's address bar) and the variable is not defined in gallery.php. Any idea what could possibly cause this different behavior? Alternatively, any other way I couldn't think of which could achieve the same effect described in the first three lines is perfectly fine. Old question What I need to do is rewriting this address: (1) http://localhost/wordpress/fake/text-value to (2) http://localhost/wordpress/gallery?somevar=text-value Notes: the remapping must be transparent: the user always has to see address (1) gallery is a permalink to a wordpress page, not a real address I basically need to rewrite the address first (to modify it) and then feed it back to mod rewrite again (to let wordpress parse it its own way). Problems if I simply do RewriteRule ^fake$ http://localhost/wordpress/gallery [L] it works but the address in the browser changes, which is no good, if I do RewriteRule ^fake$ /wordpress/gallery [L] I get a 404. I tried different flags instead of [L] but to no avail. How can I get this to work? EDIT: full .htaccess # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteRule ^fake$ /wordpress/gallery [R] RewriteBase /wordpress/ RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /wordpress/index.php [L] </IfModule> # END WordPress

  Hi, I have a question about the loop construct in Python in the form of: for x in y: In my case y is a line read from a file and x is separate characters. I would like to put a space after every pair of characters in the output, like this: aa bb cc dd etc. So, I would like to know the current iteration. Is it possible, or do I need to use a more traditional C style for loop with an index?

• newbie problems with codeigniter

  - by Patrick

  hi, i'm trying to learn codeigniter (following a book) but don't understand why the web page comes out empty. my controller is class Welcome extends Controller { function Welcome() { parent::Controller(); } function index() { $data['title'] = "Welcome to Claudia's Kids"; $data['navlist'] = $this->MCats->getCategoriesNav(); $data['mainf'] = $this->MProducts->getMainFeature(); $skip = $data['mainf']['id']; $data['sidef'] = $this->MProducts->getRandomProducts(3, $skip); $data['main'] = "home"; $this->load->vars($data); $this->load->view('template'); } the view is: <--doctype declaration etc etc.. --> </head> <body> <div id="wrapper"> <div id="header"> <?php $this->load->view('header');?> </div> <div id='nav'> <?php $this->load->view('navigation');?> </div> <div id="main"> <?php $this->load->view($main);?> </div> <div id="footer"> <?php $this->load->view('footer');?> </div> </div> </body> </html> Now I know the model is passing back the right variables, but the page appears completely blank. I would expect at least to see an error, or the basic html structure, but the page is just empty. Moreover, the controller doesn't work even if I modify it as follows: function index() { echo "hello."; } What am I doing wrong? Everything was working until I made some changes to the model - but even if I delete all those new changes, the page is still blank.. i'm really confused! thanks, P.

• How do I create/use a Fluent NHibernate convention to automap UInt32 properties to an SQL Server 200

  - by dommer

  I'm trying to use a convention to map UInt32 properties to a SQL Server 2008 database. I don't seem to be able to create a solution based on existing web sources, due to updates in the way Fluent NHibernate works - i.e. examples are out of date. I'm trying to have NHibernate generate the schema (via ExposeConfiguration). I'm happy to have NHibernate map it to anything sensible (e.g. bigint). Here's my code as it currently stands (which, when I try to expose the schema, fails due to SQL Server not supporting UInt32). Apologies for the code being a little long, but I'm not 100% sure what is relevant to the problem, so I'm erring on the side of caution. Most of it is based on this post. The error reported is: System.ArgumentException : Dialect does not support DbType.UInt32 I think I'll need a relatively comprehensive example, as I don't seem to be able to pull the pieces together into a working solution, at present. FluentConfiguration configuration = Fluently.Configure() .Database(MsSqlConfiguration.MsSql2008 .ConnectionString(connectionString)) .Mappings(mapping => mapping.AutoMappings.Add( AutoMap.AssemblyOf<Product>() .Conventions.Add<UInt32UserTypeConvention>())); configuration.ExposeConfiguration(x => new SchemaExport(x).Create(false, true)); namespace NHibernateTest { public class UInt32UserTypeConvention : UserTypeConvention<UInt32UserType> { // Empty. } } namespace NHibernateTest { public class UInt32UserType : IUserType { // Public properties. public bool IsMutable { get { return false; } } public Type ReturnedType { get { return typeof(UInt32); } } public SqlType[] SqlTypes { get { return new SqlType[] { SqlTypeFactory.Int32 }; } } // Public methods. public object Assemble(object cached, object owner) { return cached; } public object DeepCopy(object value) { return value; } public object Disassemble(object value) { return value; } public new bool Equals(object x, object y) { return (x != null && x.Equals(y)); } public int GetHashCode(object x) { return x.GetHashCode(); } public object NullSafeGet(IDataReader rs, string[] names, object owner) { int? i = (int?)NHibernateUtil.Int32.NullSafeGet(rs, names[0]); return (UInt32?)i; } public void NullSafeSet(IDbCommand cmd, object value, int index) { UInt32? u = (UInt32?)value; int? i = (Int32?)u; NHibernateUtil.Int32.NullSafeSet(cmd, i, index); } public object Replace(object original, object target, object owner) { return original; } } }
