  • Using nodereference + views to create combined view

    - by Ian Silber
    I'm trying to set up a relational View but not sure how to do it. Here's an example of what I'm going for using the node types Artist and Song. Artist Song Length Bob Dylan Like a Rolling Stone 2:00 Bruce Springsteen Atlantic City 4:00 Burce Springsteen Born to Run 5:24 Van Morrison Domino 3:22 Van Morrison Brown Eyed Girl 4:30 Assuming I have an Artist node type that has a node reference to Song (set to unlimited) and a Song data type with an additional field for length, how would I go about configuring the view to output this view? Thanks! Ian

  • UTF-8 GET using Indy 10.5.8.0 and Delphi XE2

    - by Bogdan Botezatu
    I'm writing my first Unicode application with Delphi XE2 and I've stumbled upon an issue with GET requests to an Unicode URL. Shortly put, it's a routine in a MP3 tagging application that takes a track title and an artist and queries Last.FM for the corresponding album, track no and genre. I have the following code: function GetMP3Info(artist, track: string) : TMP3Data //<---(This is a record) var TrackTitle, ArtistTitle : WideString; webquery : WideString; [....] WebQuery := UTF8Encode('http://ws.audioscrobbler.com/2.0/?method=track.getcorrection&api_key=' + apikey + '&artist=' + artist + '&track=' + track); //[processing the result in the web query, getting the correction for the artist and title] // eg: for artist := Bucovina and track := Mestecanis, the corrected values are //ArtistTitle := Bucovina; // TrackTitle := Mestecani?; //Now here is the tricky part: webquery := UTF8Encode('http://ws.audioscrobbler.com/2.0/?method=track.getInfo&api_key=' + apikey + '&artist=' + unescape(ArtistTitle) + '&track=' + unescape(TrackTitle)); //the unescape function replaces spaces (' ') with '+' to comply with the last.fm requests [some more processing] end; The webquery looks in a TMemo just right (http://ws.audioscrobbler.com/2.0/?method=track.getInfo&api_key=e5565002840xxxxxxxxxxxxxx23b98ad&artist=Bucovina&track=Mestecani?) Yet, when I try to send a GET() to the webquery using IdHTTP (with the ContentEncoding property set to 'UTF-8'), I see in Wireshark that the component is GET-ing the data to the ANSI value '/2.0/?method=track.getInfo&api_key=e5565002840xxxxxxxxxxxxxx23b98ad&artist=Bucovina&track=Mestec?ni?' Here is the full headers for the GET requests and responses: GET /2.0/?method=track.getInfo&api_key=e5565002840xxxxxxxxxxxxxx23b98ad&artist=Bucovina&track=Mestec?ni? HTTP/1.1 Content-Encoding: UTF-8 Host: ws.audioscrobbler.com Accept: text/html, */* Accept-Encoding: identity User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.23) Gecko/20110920 Firefox/3.6.23 SearchToolbar/1.22011-10-16 20:20:07 HTTP/1.0 400 Bad Request Date: Tue, 09 Oct 2012 20:46:31 GMT Server: Apache/2.2.22 (Unix) X-Web-Node: www204 Access-Control-Allow-Origin: * Access-Control-Allow-Methods: POST, GET, OPTIONS Access-Control-Max-Age: 86400 Cache-Control: max-age=10 Expires: Tue, 09 Oct 2012 20:46:42 GMT Content-Length: 114 Connection: close Content-Type: text/xml; charset=utf-8; <?xml version="1.0" encoding="utf-8"?> <lfm status="failed"> <error code="6"> Track not found </error> </lfm> The question that puzzles me is am I overseeing anything related to setting the property of the tidhttp control? How can I stop the well-formated URL i'm composing in the application from getting wrongfully sent to the server? Thanks.

  • Determine if it has been 6 months since birthday in c#

    - by Longball27
    Hi, Sorry if this is a duplicate, but i think I've seen enough of Google for one day! My application needs to adjust a clients current age by +0.5 if it has been 6 months since their birthday. The code should look something like this, but how many ticks would there be in 6 months? if (DateTime.Today - dateOfBirth.Date > new TimeSpan(6)) { adjust = 0.5M; } else { adjust = 0M; } Thanks in advance

  • How to update a collection based on another collection in MongoDB?

    - by Sean Zhu
    Now I get two collections: coll01 and coll02. And the structure of coll01 is like this: { id: 01, name: "xxx", age: 30 } and the structure of coll02 is like: { id: 01, name: "XYZ" gender: "male" } The two id fields in the both collection are indices. And the numbers of documents in these two collections are same. And what I want to do in traditional SQL is : update coll01, coll02 set coll01.name = coll02.name where coll01.id = coll02.id

  • Java: Finding objects in collections.

    - by Jake
    This problem occurs over and over. I have some complicated object, such as a Cat, which has many properties, such as age, favorite cat food, and so forth. A bunch of Cats are stored in a Java Collection, and I need to find all the Cats that are aged 3, or those whose favorite cat food is Whiskas. Surely, I can write a custom method that finds those Cats with a specific property, but this gets cumbersome with many properties; is there some generic way of doing this?

  • A view model mvvm design issue

    - by Chen Kinnrot
    the best way to explain is with example so: this is the model public class Person { public int age; public string name; } this is the view model public class PersonVM { } my question is: should the vm expose the person to the datga template or encapsulate the model properties with his own properties?

  • Why does firefox round-trip to the server to determine whether my files are modifed?

    - by erikkallen
    I have some static content on my web site that I have set up caching for (using Asp.NET MVC). According to Firebug, the first time I open the page, Firefox sends this request: GET /CoreContent/Core.css?asm=0.7.3614.34951 Host: 127.0.0.1:3916 User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5 (.NET CLR 3.5.30729) Accept: text/css,*/*;q=0.1 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive Referer: http://127.0.0.1:3916/Edit/1/101 Cookie: .ASPXAUTH=52312E5A802C1A079E2BA29AA2BFBC5A38058977B84452D62ED52855D4164659B4307661EC73A307BFFB2ED3871C67CB3A9AAFDB3A75A99AC0A21C63A6AADE9A11A7138C672E75125D9FF3EFFBD9BF62 Pragma: no-cache Cache-Control: no-cache Which my server replies to with this: Server: ASP.NET Development Server/9.0.0.0 Date: Mon, 23 Nov 2009 18:44:41 GMT X-AspNet-Version: 2.0.50727 X-AspNetMvc-Version: 1.0 Cache-Control: public, max-age=31535671 Expires: Tue, 23 Nov 2010 18:39:12 GMT Last-Modified: Mon, 23 Nov 2009 18:39:12 GMT Vary: * Content-Type: text/css Content-Length: 15006 Connection: Close So far, so good. However, if I refresh Firefox (not a cache-clearing refresh, just a normal one), during that refresh cycle Firefox will once again go to the server with this request: GET /CoreContent/Core.css?asm=0.7.3614.34951 Host: 127.0.0.1:3916 User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5 (.NET CLR 3.5.30729) Accept: text/css,*/*;q=0.1 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 300 Connection: keep-alive Referer: http://127.0.0.1:3916/Edit/1/101 Cookie: .ASPXAUTH=52312E5A802C1A079E2BA29AA2BFBC5A38058977B84452D62ED52855D4164659B4307661EC73A307BFFB2ED3871C67CB3A9AAFDB3A75A99AC0A21C63A6AADE9A11A7138C672E75125D9FF3EFFBD9BF62 If-Modified-Since: Mon, 23 Nov 2009 18:39:20 GMT Cache-Control: max-age=0 to which my server responds 304 Not Modified. Why does Firefox issue this second request? In the first response, I said that the cache does not expire for a year (I intend to use query parameters whenever things change). Do I have to add another response header to prevent this extra roundtrip? Edit: It does not matter whether I press refresh, or whether I go to the page again (or a different URL, which references the same external files). Firefox does the same again. Also, I don't claim this to be a bug in FF, I just wonder if there is another header I can set which means "This document will never change, don't bother me again".

  • Constructor within a constructor

    - by Chiramisu
    Is this a bad idea? Does calling a generic private constructor within a public constructor create multiple instances, or is this a valid way of initializing class variables?

  • Sort by ranking algorithm using will-paginate

    - by bearwithclaws
    I'm creating a digg-like site using Ruby on Rails that ranks the item (based on this algorithm). I'm using the will-paginate gem list the items in pages. The problem is, will-paginate only allows me to insert ':order =' based on the table data. I would like to make will-paginate to sort by a number which is calculated using a function based on different fields on the table (e.g number of votes, age hours). How can I do that?

  • php search and replace

    - by Dave
    I am trying to create a database field merge into a document (rtf) using php i.e if I have a document that starts Dear Sir, Customer Name: [customer_name], Date of order: [order_date] After retrieving the appropriate database record I can use a simple search and replace to insert the database field into the right place. So far so good. I would however like to have a little more control over the data before it is replaced. For example I may wish to Title Case it, or convert a delimited string into a list with carriage returns. I would therefore like to be able to add extra formatting commands to the field to be replaced. e.g. Dear Sir, Customer Name: [customer_name, TC], Date of order: [order_date, Y/M/D] There may be more than one formatting command per field. Is there a way that I can now search for these strings? The format of the strings is not set in stone, so if I have to change the format then I can. Any suggestions appreciated.

  • How do I add a filter button to this pagination?

    - by ClarkSKent
    Hey, I want to add a button(link), that when clicked will filter the pagination results. I'm new to php (and programming in general) and would like to add a button like 'Automotive' and when clicked it updates the 2 mysql queries in my pagination script, seen here: As you can see, the category automotive is hardcoded in, I want it to be dynamic, so when a link is clicked it places whatever the id or class is in the category part of the query. 1: $record_count = mysql_num_rows(mysql_query("SELECT * FROM explore WHERE category='automotive'")); 2: $get = mysql_query("SELECT * FROM explore WHERE category='automotive' LIMIT $start, $per_page"); This is the entire current php pagination script that I am using: <?php //connecting to the database $error = "Could not connect to the database"; mysql_connect('localhost','root','root') or die($error); mysql_select_db('ajax_demo') or die($error); //max displayed per page $per_page = 2; //get start variable $start = $_GET['start']; //count records $record_count = mysql_num_rows(mysql_query("SELECT * FROM explore WHERE category='automotive'")); //count max pages $max_pages = $record_count / $per_page; //may come out as decimal if (!$start) $start = 0; //display data $get = mysql_query("SELECT * FROM explore WHERE category='automotive' LIMIT $start, $per_page"); while ($row = mysql_fetch_assoc($get)) { // get data $name = $row['id']; $age = $row['site_name']; echo $name." (".$age.")<br />"; } //setup prev and next variables $prev = $start - $per_page; $next = $start + $per_page; //show prev button if (!($start<=0)) echo "<a href='pagi_test.php?start=$prev'>Prev</a> "; //show page numbers //set variable for first page $i=1; for ($x=0;$x<$record_count;$x=$x+$per_page) { if ($start!=$x) echo " <a href='pagi_test.php?start=$x'>$i</a> "; else echo " <a href='pagi_test.php?start=$x'><b>$i</b></a> "; $i++; } //show next button if (!($start>=$record_count-$per_page)) echo " <a href='pagi_test.php?start=$next'>Next</a>"; ?>
