  • Loop not working when I try to traverse a Simple XML Object

    - by Ben Shelock
    I'm trying to loop through the results from the Last.fm API but it's not working. function get_url($url){ $ch = curl_init(); curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,5); $content = curl_exec($ch); curl_close($ch); return $content; } $xml = get_url('http://ws.audioscrobbler.com/2.0/?method=album.search&album=kid%20a&api_key=b25b959554ed76058ac220b7b2e0a026'); $doc = new SimpleXMLElement($xml); $albums = $doc->results->albummatches; foreach($albums as $album){ echo $album->album->name; } This just shows the first album. If I change the code within the foreach loop to echo $album->name; it shows nothing at all. What am I doing wrong?

  • Hibernate - why use many-to-one to represent a one-to-one?

    - by aberrant80
    I've seen people use many-to-one mappings to represent one-to-one relationships. I've also read this in a book by Gavin King and on articles. For example, if a customer can have exactly one shipping address, and a shipping address can belong to only one customer, the mapping is given as: <class name="Customer" table="CUSTOMERS"> ... <many-to-one name="shippingAddress" class="Address" column="SHIPPING_ADDRESS_ID" cascade="save-update" unique="true"/> ... </class> The book reasons as (quoting it): "You don't care what's on the target side of the association, so you can treat it like a to-one association without the many part." My question is, why use many-to-one and not one-to-one? What is it about a one-to-one that makes it a less desirable option to many-to-one? Thanks.

  • Pushing View from UITableView Problem

    - by golfromeo
    Basically, what I want is to be able to press a record in a table, and have it push to another view. To do this, I created a nib file and a UIViewController subclass (for the "pushed" view). I set the nib file's "File Owner" to be the controller I created. Then, in the view controller of the table that will push that view, I set the didSelectRowIndexAtPath: method to include the following: SearchTableController *vc = [[SearchTableController alloc] initWithNibName:@"SearchTable" bundle:[NSBundle mainBundle]]; [self.navigationController pushViewController:vc animated:YES]; [vc release]; (where "SearchTableController" is the name of the UIViewController subclass and "SearchTable" is the name of the nib file) However, when I run this code and click on the record, nothing happens- the app doesn't crash, but the view doesn't get pushed. The code is getting run, because it works when I NSLog(), but it doesn't seem to be pushing the view. Thanks for any help in advance.

  • Is this a possible way to get Drupal AD SSO?

    - by JollyRogers
    I'm currently building a Drupal website in an Active Directory environment. One of the site's requirements is Single Sign On, which to date seems to be impossible because there is no Kerberos SPNEGO/GSSAPI auth module for drupal. I've come up with an idea on how SSO could be attempted on IIS. Since IIS has the option to require Kerberos authentication, we can let IIS handle authentication and use the AUTH_USER server variable to pass the authorized user name to the an 'improved' LDAP_auth module. The LDAP_auth module would then check the user name (but not password since it doesn't know or need to know the password) against LDAP to get the user's roles. (AD groups) Does anyone know if this is possible? If so, does anyone have any ideas on how to implement this?

  • Use a ContextLoaderListener in accordance with DispatchServlet

    - by Phuong Nguyen de ManCity fan
    I want to use both ContextLoaderListener (so that I can pass Spring Beans to my servlet) as well as DispatchServlet (Spring MVC). However, currently I have to pass init param to these both class initializer: <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/spring/app-config.xml </param-value> So, I use the same xml for these both classes. Wonder if it would lead to my beans being initialized twice? If yes, how would I do to avoid that?

  • Drawing up a session value within SQL query? PHP and MySQL

    - by Derek
    Hi, on one of my web pages I want my manager user to view all activities assigned to them (personally). In order to do this, I need something like this: $sql = "SELECT * FROM activities WHERE manager = $_SESSION['SESS_FULLNAME']"; Now obviously this syntax is all wrong, but because I am new to this stuff, is there a way I can call up the full name from the user's session within a query? This is so that when I call up the database values to be displayed within the web page, only the activities for the manager who is logged in is displayed. For example, the activities table has a manager column of a full name entry. Any help is much appreciated. Thanks.

  • Can I use a string variable to reference a class variable?

    - by rson
    Here's the scenario: I have an external swf file with x number of movieclips in its library that I load into a containing swf. Each MC in the external swf is linked with a class name and referenced on frame 1 as such var unique1:lineSequence1 = new lineSequence1(); the unique1 variable name will match a string variable I create in the containing swf: function initLines():void{ lineLoader = new Loader(); lineLoader.load(new URLRequest("theLines.swf")); //load external swf lineLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, linesLoaded); } function linesLoaded(e:Event):void{ var loadedswf:MovieClip = e.target.content as MovieClip; var initialLines = projects[0].pageid; //projects is an xmllist trace("initialLines: "+initialLines); //returns "initialLines: unique1" lines_holder_mc.addChild(loadedswf.[initialLines]); } I would like to use the initialLines variable as the reference to unique1 instead of hardcoding unique1 into loadedswf.unique1 to reference said variable in the loaded swf.

  • Django: Data corrupted after loading? (possible programmer error)

    - by Rosarch
    I may be loading data the wrong way. excerpt of data.json: { "pk": "1", "model": "myapp.Course", "fields": { "name": "Introduction to Web Design", "requiredFor": [9], "offeringSchool": 1, "pre_reqs": [], "offeredIn": [1, 5, 9] } }, I run python manage.py loaddata -v2 data: Installed 36 object(s) from 1 fixture(s) Then, I go to check the above object using the Django shell: >>> info = Course.objects.filter(id=1) >>> info.get().pre_reqs.all() [<Course: Intermediate Web Programming>] # WRONG! There should be no pre-reqs >>> from django.core import serializers >>> serializers.serialize("json", info) '[{"pk": 1, "model": "Apollo.course", "fields": {"pre_reqs": [11], "offeredIn": [1, 5, 9], "offeringSchool": 1, "name": "Introduction to Web Design", "requiredFor": [9]}}]' The serialized output of the model is not the same as the input that was given to loaddata. The output has a non-empty pre_req list, whereas the input's pre_reqs field is empty. What am I doing wrong?

  • Can you pull the connectionString for a log4net AdoNetAppender from elsewhere in a web.config file?

    - by mrsharps
    Hey all. This is my first StackOverflow question. I'm already have a db connection string in my web.config file. I scanned the log4net docs, but can't seem to find a way to use it within the log4net section of my web.config file. Is is possible to do something like this? <connectionStrings> <add name="connStr" connectionString="Data Source=localhost; ..." /> </connectionStrings> <log4net> <appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender"> <connectionString connectionStringName="connStr"/> ... </log4net> Thanks!

  • Generate digital signature using VBA

    - by tputkonen
    I have text cells of arbitrary length in Excel's column A. Using a private key, I want to generate digital signature for data in column A into the cell in column B. I'm looking for a macro implementation for the digital signature algorithm - I don't think one ships with Excel, but is there an addon available? It must be possible to easily verify correctness of the signature in other environments as well.

  • Is it possible to query a XML file with SQL?

    - by Monty
    Currently I'm working on a case where we don't want to change to much on a c#/wpf program, but like to add a feature. Currently we allow certain users to add sql queries to a database to retrieve customer data, hereby a custom connection string/ provider name must be specified. With this information it's possible to create the connection and obtain the data with c#. However we like to add the possibility to allow that user group to query XML files too, with a certain connection string/ provider name. I just had a look for possibities in .net to do that, but can't seem to find a decent way... Is something like this possible? (OleDb/ODBC way maybe?) Thanks in advance.

  • Navigating by foreign keys in ADO.NET Entity Framework/MySQL

    - by Werg38
    I am using ASP.NET MVC2 on top of a MySQL database in VS2008. I am using the MySQL ADO.NET connector 6.2.3 to provide the connection for the ADO.NET Entity Data Model. This is mostly working ok, however navigating via foreign keys is causing me a real headache! Here is a simplified example.. Car (Table) CarID PK Colour Doors ManufacturerID FK Manufacturer (Table) ManufacturerID PK Name In the edmx file I can see the 1-many relationship shown as a navigation property in the both the Car and Manufacturer tables. I create a Models.CarRepository that allows me to returns a IQueryable. At the View I want to be able to display the Manufacturer.Name for each car. This is not accessible via the object I get returned. What is best way to implement this? Have I encountered a limitation of the Entity Framework/MySQL combination?

  • group_concat on an empty join in MySQL

    - by Yossarian
    Hello, I've got the following problem: I have two tables: (simplified) +--------+ +-----------+ | User | | Role | +--------+ +-----------+ | ID<PK> | | ID <PK> | +--------+ | Name | +-----------+ and M:N relationship between them +-------------+ | User_Role | +-------------+ | User<FK> | | Role<FK> | +-------------+ I need to create a view, which selects me: User, and in one column, all of his Roles (this is done by group_concat). I've tried following: SELECT u.*, group_concat(r.Name separator ',') as Roles FROM User u LEFT JOIN User_Role ur ON ur.User=u.ID LEFT JOIN Role r ON ur.Role=r.ID GROUP BY u.ID; However, this works for an user with some defined roles. Users without role aren't returned. How can I modify the statement, to return me User with empty string in Roles column when User doesn't have any Role? Explanation: I'm passing the SQL data directly to a grid, which then formats itself, and it is easier for me to create slow and complicated view, than to format it in my code. I'm using MySQL

  • Load only some columns with Hibernate native SQL queries

    - by Alessandro Dionisi
    I have a table on the database and I want to load only some columns from the result set. I defined a native sql query in the hbm file: <sql-query name="query"> <return alias="r" class="RawData"/> <![CDATA[ SELECT DESCRIPTION as {r.description} FROM RAWD_RAWDATAS r WHERE r.RAWDATA_ID=? ]]> </sql-query> This query however fails with error: could not read column value from result set: RAWDATA1_14_0_; Invalid column name SQL Error: 17006, SQLState: null, because Hibernate tries to load all fields from the result set. I found also a bug in Hibernate JIRA (http://opensource.atlassian.com/projects/hibernate/browse/HHH-3035). Anyone knows how to accomplish this task with a workaround?

  • Regex to match a Java method signature

    - by nitesh
    I am having this particular requirement where a method has to be identified by different regular expressions for different components. For example, there need to be a regex for return parameter, one for method name, one for argument type and one for argument name. I was able to come up with an expression till this step as follows - ([^,]+) ([^,]+)\((([^,]+) ([^,]+))\) It works well for a method signature like - ReturnType foo(Arg parameter) The regular expression identifies ReturnType, foo, Arg and parameter separately. Now the problem is that a method can have no/one/multiple arguments separated by commas. I am not able to get a repeating expression for this. Help will be appreciated.

  • Interconnecting Emulator Instances Android

    - by blah01
    Hi all I want to communicate two emulators via DatagramSocket in Android. Each of them is a Node in a P2P system. Thus each of them has a server Thread and client Thread (created per GUI event). This is how I create server public static final String SERVERIP = "10.0.2.15"; //... run() { InetAddress serverAddr = InetAddress.getByName(SERVERIP); DatagramSocket socket = new DatagramSocket(SERVERPORT,serverAddr); while(true) { byte[] buf = new byte[29]; DatagramPacket packet = new DatagramPacket(buf, buf.length); socket.receive(packet); //... } } The port is given by the user during initializing application. The client part (requesting some data) InetAddress serverAddr = InetAddress.getByName("10.0.2.2"); //... Log.i("Requester", "Trying to connect to device port = "+target); DatagramSocket socketJ = new DatagramSocket(); byte[] bufJ = Adaptor.createStringMsg(Adaptor.createJoingMsg(id, Location.getX(), Location.getY())).getBytes(); DatagramPacket packetJ = new DatagramPacket(bufJ, bufJ.length, serverAddr, target); Log.i("Requester", "Sending: '" + new String(bufJ) + "'"); socketJ.send(packetJ); Log.i("Requester", "Done."); Some additional info. The Node1 (emulatorA) has a server on port 8000 and Node2 (emulatorB) has a server on port 8001. The target port for "client part" is read properly. What tried to do is to set the redirection as such: //emulatorA redir add tcp:8000:8000 //emulatorB redir add tcp:8001:8001 However I can not get any communication beetwen those 2 emulators. As far as I understood the android tutorial about it should work like this redir add tcp:localhostPort:emulatorPort. I'm stuck with it :/. Can anyone point me the mistake or give some good advice. For the record while I was testing communication on a single device (client faking other node) everything worked, so I don't think there is a bug in the code. Btw does any one knows how can I get 2 set of logs for those 2 emulators (logA, logB)? It would help me a lot.

  • Exercise 7.9 in "How to Think Like a Computer Scientist (python)" measuring occurrences of a character in a string

    - by Abie
    The question is how to write a program that measures how many times a character appears in a string in a generalizable way in python. The code that I wrote: def countLetters(str, ch): count=0 index=0 for ch in str: if ch==str[index]: count=count+1 index=index+1 print count when I use this function, it measures the length of the string instead of how many times the character occurs in the string. What did I do wrong? What is the right way to write this code?
