  • How can i use Google-o-Meter or Google Vizualisation API with Jenkins

    - by kamal
    Here is a sample that displays a static chart: google.load("visualization", "1.0", {packages:["imagechart"]}); google.setOnLoadCallback(drawChart); function drawChart() { var dataTable = new google.visualization.DataTable(); dataTable.addColumn('string'); dataTable.addColumn('number'); dataTable.addColumn('string'); // Row data is [chl, data point, point label] dataTable.addRows([ ['January',40,undefined], ['February',60,'Initial recall'], ['March',60,'Product withdrawn'], ['April',45,undefined], ['May',47,'Relaunch'], ['June',75,undefined], ['July',70,undefined], ['August',72,undefined] ]); var options = {cht: 'lc', chds:'0,160', annotationColumns:[{column:2, size:12, type:'flag', priority:'high'},]}; var chart = new google.visualization.ImageChart(document.getElementById('line_div')); chart.draw(dataTable, options); } How can i replace the static values and variables in dataTable.addRows([ with real live data ? In case the compete code is not visible, refer to : http://code.google.com/apis/visualization/documentation/gallery/genericimagechart.html When this Javascript is copied to the "Description" it renders a chart, what i want to know is how to replace the name/value in dataTable.addRows, to the name/values coming from Jenkins

  • How can I use PHP Mail() function within PHP-FPM? On Nginx?

    - by TheBlackBenzKid
    I have searched everywhere for this and I really want to resolve this. In the past I just end up using an SMTP service like SendGrid for PHP and a mailing plugin like SwiftMailer. However I want to use PHP. Basically my setup (I am new to server setup, and this is my personal setup following a tutorial) Nginx Rackspace Cloud PHP 5.3 PHP-FPM Ubuntu 11.04 My phpinfo() returns this about the Mail entries: mail.log no value mail.add_x_header On mail.force_extra_parameters no value sendmail_from no value sendmail_path /usr/sbin/sendmail -t -i SMTP localhost smtp_port 25 Can someone help me to as why Mail() will not work - my script is working on all other sites, it is a normal mail command. Do I need to setup logs or enable some PHP port on the server? My Sample script <? # FORMS VARS // $to = $customers_email; // $to = $customers_email; $to = $_GET["customerEmailFromForm"]; $subject = "Thank you for contacting Real-Domain.com"; $message = " <html> <head> </head> <body> Thanks, your message was sent and our team will be in touch shortly. <img src='http://cdn.com/emails/thank_you.jpg' /> </body> </html> "; $headers = "MIME-Version: 1.0" . "\r\n"; $headers .= "Content-type:text/html;charset=iso-8859-1" . "\r\n"; $headers .= 'From: <[email protected]>' . "\r\n"; // SEND MAIL mail($to,$subject,$message,$headers); ?> Thanks

  • IUsable: controlling resources in a better way than IDisposable

    - by Ilya Ryzhenkov
    I wish we have "Usable" pattern in C#, when code block of using construct would be passed to a function as delegate: class Usable : IUsable { public void Use(Action action) // implements IUsable { // acquire resources action(); // release resources } } and in user code: using (new Usable()) { // this code block is converted to delegate and passed to Use method above } Pros: Controlled execution, exceptions The fact of using "Usable" is visible in call stack Cons: Cost of delegate Do you think it is feasible and useful, and if it doesn't have any problems from the language point of view? Are there any pitfalls you can see? EDIT: David Schmitt proposed the following using(new Usable(delegate() { // actions here }) {} It can work in the sample scenario like that, but usually you have resource already allocated and want it to look like this: using (Repository.GlobalResource) { // actions here } Where GlobalResource (yes, I know global resources are bad) implements IUsable. You can rewrite is as short as Repository.GlobalResource.Use(() => { // actions here }); But it looks a little bit weird (and more weird if you implement interface explicitly), and this is so often case in various flavours, that I thought it deserve to be new syntactic sugar in a language.

  • Node.js fetching Twitter Streaming API - EADDRNOTAVAIL

    I have the following code written in node.js to access to the Twitter Streaming API. If I curl the URL below, it works. However, I cannot get it to work with my code. var https = require('https'); https.request('https://USERNAME:[email protected]/1.1/statuses/sample.json', function(res) { res.on('data', function(chunk) { var d = JSON.parse(chunk); console.log(d); }); }); But I receive the following node.js:201 throw e; // process.nextTick error, or 'error' event on first tick ^ Error: connect EADDRNOTAVAIL at errnoException (net.js:642:11) at connect (net.js:525:18) at Socket.connect (net.js:589:5) at Object.<anonymous> (net.js:77:12) at new ClientRequest (http.js:1073:25) at Object.request (https.js:80:10) at Object.<anonymous> (/Users/jordan/Projects/twitter-stream/app.js:3:7) at Module._compile (module.js:441:26) at Object..js (module.js:459:10) at Module.load (module.js:348:31) If anyone can offer an alternative solution, or explain to me why this doesn't work, I would be very grateful.

  • CascadingDropDown taking two parameters...

    - by WeeShian
    I have a page with 3 dropdownlist, 2nd and 3rd dropdownlist are added with CascadingDropDown. 3rd dropdownlist will take parameters from 1st and 2nd dropdownlist. So, in current example for CascadingDropDown i have found from google, they are only passing one parameter to the WebService method. How can pass two parameters to the service method, so that my 3rd dropdownlist will based on the SelectedValue of 1st and 2nd dropdownlist? <WebMethod()> _ Public Function GetTeams(ByVal knownCategoryValues As String, ByVal category As String) As CascadingDropDownNameValue() Dim strConnection As String = ConfigurationManager.ConnectionStrings("nerdlinessConnection").ConnectionString Dim sqlConn As SqlConnection = New SqlConnection(strConnection) Dim strTeamQuery As String = "SELECT * FROM TEAM WHERE conf_id = @confid" Dim cmdFetchTeam As SqlCommand = New SqlCommand(strTeamQuery, sqlConn) Dim dtrTeam As SqlDataReader Dim kvTeam As StringDictionary = CascadingDropDown.ParseKnownCategoryValuesString(knownCategoryValues) Dim intConfId As Integer If Not kvTeam.ContainsKey("Conference") Or Not Int32.TryParse(kvTeam("Conference"), intConfId) Then Return Nothing End If cmdFetchTeam.Parameters.AddWithValue("@confid", intConfId) Dim myTeams As New List(Of CascadingDropDownNameValue) sqlConn.Open() dtrTeam = cmdFetchTeam.ExecuteReader While dtrTeam.Read() Dim strTeamName As String = dtrTeam("team_name").ToString Dim strTeamId As String = dtrTeam("team_id").ToString myTeams.Add(New CascadingDropDownNameValue(strTeamName, strTeamId)) End While Return myTeams.ToArray End Function This is the sample code i found! As you can see in the code, '@confid' will be passed from 2nd dropdownlist! So, hw do i modify this code to get the selected value from 1st dropdownlist as well??

  • Images not responsive although in responsive container

    - by Darren Sweeney
    I have the following: <div id="hp_imgs"> <img src="/images/hp/1.jpg"> <img src="/images/hp/2.jpg"> <img src="/images/hp/3.jpg"> <img src="/images/hp/4.jpg"> <img src="/images/hp/5.jpg"> <img src="/images/hp/6.jpg"> <img src="/images/hp/7.jpg"> <img src="/images/hp/8.jpg"> </div> The images were sized when created to form a grid of sorts, so need to be in the order where they are. Consequently, when/if the page is resized I want the images to resize and stay where they are. Here's what I'm trying but images are simply staying the same size and not resizing: #hp_imgs { width:66%; float:left; } #hp_imgs img { float:left; margin:2px; border-radius:4px; display: block; max-width:100%; height:100%; } Is there a better/different way to achieve this?

  • Are there any ASP.NET MVC subscription-based starter kits or examples?

    - by Wayne M
    Basically something that handles the low-level "plumbing" code for a subscription-based service. I see a lot of things dealing with basic membership, but nothing that handles the subscription aspect (recurring billing, automated jobs for setting up billing, notification for billing, etc). This might be the one thing that keeps me from using ASP.NET MVC for my SaaS idea, since it would take a fair amount of development time to write my own; if I go with my other option, Ruby on Rails, I can buy a kit that does all of this for $250. I haven't found anything even remotely close to this for .NET - all of the SaaS sample apps I've seen are more like StackOverflow et all where you have one site that multiple people log on to, not the web application model where you have subscribers who are billed monthly, each of whom has users and other entities (e.g. Customers, Tasks, etc) for their own site. Is there anything similar for ASP.NET, or some kind of guidelines for writing my own if I have to, so I don't waste too much time? As a startup that means that I'm doing all the coding myself. I've found this, but it seems to only be for billing and didn't seem to have much (any?) documentation on exactly how to set it up.

  • Implementing parts of rfc4226 (HOTP) in mysql

    - by Moose Morals
    Like the title says, I'm trying to implement the programmatic parts of RFC4226 "HOTP: An HMAC-Based One-Time Password Algorithm" in SQL. I think I've got a version that works (in that for a small test sample, it produces the same result as the Java version in the code), but it contains a nested pair of hex(unhex()) calls, which I feel can be done better. I am constrained by a) needing to do this algorithm, and b) needing to do it in mysql, otherwise I'm happy to look at other ways of doing this. What I've got so far: -- From the inside out... -- Concatinate the users secret, and the number of time its been used -- find the SHA1 hash of that string -- Turn a 40 byte hex encoding into a 20 byte binary string -- keep the first 4 bytes -- turn those back into a hex represnetation -- convert that into an integer -- Throw away the most-significant bit (solves signed/unsigned problems) -- Truncate to 6 digits -- store into otp -- from the otpsecrets table select (conv(hex(substr(unhex(sha1(concat(secret, uses))), 1, 4)), 16, 10) & 0x7fffffff) % 1000000 into otp from otpsecrets; Is there a better (more efficient) way of doing this?

  • PHP Switch and Login

    - by Steve Rivera
    I'm fairly new with PHP and I am messing around with a login/registration system. I setup my sample website using a PHP-SWITCH script I found a while back: <?php switch($_GET['id']) { default: include('home.php'); /* LOGIN PAGES */ break; case "register_form": include ('includes/user_system/register_form.php'); } ? On the registration page the form links to my "register.php" which checks the validity of the form and to check for any blank fields and so on. "register.php" is supposed to refresh the page and add a reason to what the user did wrong when submitting the form. On my "register_form.php" page, which holds the actual form. This field is hidden until the user makes a mistake. <?php if (isset($reg_error)) { ?> , please try again. My "register.php" checks the form for all the errors. Here's the bit of code that will refresh the page with the reason for the error: // Check if any of the fields are missing if (empty($_POST['username']) || empty($_POST['password']) || empty($_POST['confirmpass'])) { // Reshow the form with an error $reg_error = 'One or more fields missing'; include 'register_form.php'; Now after I submit the form without any fields filled out I get the error code, but it refreshes to the actual "register_form.php". The problem with this is that because of my PHP-SWITCH script (helps me manage the site a lot easier) I don't have any formatting on that page. The actual URL to my "register_form.php" would be: "index.php?id=register_form.php". Now I have tried several different things such as changing it to: include 'index.php?id=register_form.php' And also changing it to: header(location:index.php?id=register_form.php') Unfortunately all this does is refresh the page without the reason for the error. I know this can be easily solved by just adding a Javascript Validator but I'd like to know if it is possible to refresh the page with the error using either "include" or "header()" while having a PHP-SWITCH script on the website.

  • SHLoadImageFile(L"\\Program Files\\TrainingApp\\background.png"); whats that L in the argument for?

    - by ashishsony
    Hi, ive been working on c++ on linux for the past 2 years,and switched to windows c++ programming recently. can anyone tell me what that L is there in the argument of the function: SHLoadImageFile(L"\\Program Files\\TrainingApp\\background.png"); and on viewing certain sample code in MSVS C++ i came across hundereds of typedefs like.. LPARAM// typedef LONG_PTR LPARAM... here LONG_PTR is again typedef as __w64 long WPARAM// typedef UINT_PTR WPARAM... so there is a lot of chained typedefs.. I never saw this much of typedef chaining on c++ programming on linux using gcc.. what i want to say is that it just creates more confusion in this way for windows application programming.. while ive seen application programming on linux using frameworks like Qt.. there such things are rarely used.. so is there specific purpose in typedefining again and again on MSVSC++?? for eg.. there are typdefs like typedef int BOOL; whats the use of this when normal bool is available already..?? there are hundred other cases ive come across where just to decide what data type to use becomes so difficult.. it becomes difficult to understand a pre written code in this fashion too.. Thanks.

  • EF + UnitOfWork + SharePoint RunWithElevatedPrivileges

    - by Lorenzo
    In our SharePoint application we have used the UnitOfWork + Repository patterns together with Entity Framework. To avoid the usage of the passthrough authentication we have developed a piece of code that impersonate a single user before creating the ObjectContext instance in a similar way that is described in "Impersonating user with Entity Framework" on this site. The only difference between our code and the referred question is that, to do the impersonation, we are using RunWithElevatedPrivileges to impersonate the Application Pool identity as in the following sample. SPSecurity.RunWithElevatedPrivileges(delegate() { using (SPSite site = new SPSite(url)) { _context = new MyDataContext(ConfigSingleton.GetInstance().ConnectionString); } }); We have done this way because we expected that creating the ObjectContext after impersonation and, due to the fact that Repositories are receiving the impersonated ObjectContext would solve our requirement. Unfortunately it's not so easy. In fact we experienced that, even if the ObjectContext is created before and under impersonation circumstances, the real connection is made just before executing the query, and so does not use impersonation, which break our requirement. I have checked the ObjectContext class to see if there was any event through which we can inject the impersonation but unfortunately found nothing. Any help?

  • ClassCastException while using service

    - by Sebi
    I defined a local Service: public class ComService extends Service implements IComService { private IBinder binder = new ComServiceBinder(); public class ComServiceBinder extends Binder implements IComService.IServiceBinder { public IComService getService() { return ComService.this; } } public void test(String msg) { System.out.println(msg); } @Override public IBinder onBind(Intent intent) { return binder; } } The corresponding interface: public interface IComService { public void test(String msg); public interface IServiceBinder { IComService getService(); } } Then i try to bind the service in another activity in another application, where the same interface is available: bindService(new Intent("ch.ifi.csg.games4blue.gamebase.api.ComService"), conn, Context.BIND_AUTO_CREATE); and private ServiceConnection conn = new ServiceConnection() { @Override public void onServiceConnected(ComponentName name, IBinder service) { Log.i("INFO", "Service bound " + name); comService = ((IComService.IServiceBinder)service).getService(); serviceHandler.sendEmptyMessage(0); } @Override public void onServiceDisconnected(ComponentName arg0) { Log.i("INFO", "Service Unbound "); } }; but the line comService = ((IComService.IServiceBinder)service).getService(); always throws a 05-02 22:12:55.922: ERROR/AndroidRuntime(622): java.lang.ClassCastException: android.os.BinderProxy I can't explain why, I followed the app sample on http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/app/LocalServiceBinding.html Any hints would be nice!

  • Malloc inside another function (ANSI C)

    - by Casper
    Hi I'll go straight to it. I'm working on an assignment, where I suddenly ran into trouble. I have to allocate a struct from within another function, obviously using pointers. I've been staring at this problem for hours and tried in a million different ways to solve it. This is some sample code (very simplified): ... some_struct s; printf("Before: %d\n", &s"); allocate(&s); printf("After: %d\n", &s"); ... /* The allocation function */ int allocate(some_struct *arg) { arg = malloc(sizeof(some_struct)); printf("In function: %d\n", &arg"); return 0; } This does give me the same address before and after the allocate-call: Before: -1079752900 In function: -1079752928 After: -1079752900 I know it's probably because it makes a copy in the function, but I don't know how to actually work on the pointer I gave as argument. I tried defining some_struct *s instead of some_struct s, but no luck. I tried with: int allocate(some_struct **arg) which works just fine (the allocate-function needs to be changed as well), BUT according to the assignment I may NOT change the declaration, and it HAS to be *arg.. And it would be most correct if I just have to declare some_struct s.. Not some_struct *s. I hope I make sense and some of you out there can help me :P Thanks in advice

  • How can I test this SQL Server performance Utility?

    - by Martin Smith
    As part of my MSc I need to do a three month project later this year. I have decided to do something which will likely be useful for me in the workplace and spend the time getting to understand SQL Server internals. The deliverable for this project will be a performance advisor looking at a variety of different rules. Some static such as finding redundant indexes, some more dynamic such as using XEvents to find outlying invocations of stored procedure execution times when certain parameters are passed. I am struggling to come up with a good way of testing this though. I can obviously design a "bad" database and a synthetic workload that my tool will pick up issues on but I also need to demonstrate that it has real world utility. Looking at the self tuning database literature it is common to use TPC benchmarks but I've had a look at the TPCC site and it looks very time consuming to implement and not that good a fit to my project's testing needs in any event (I would still be able to "rig" it by the decisions I made on indexing or physical architecture). Plan A would be to find willing beta tester(s) but in the event that isn't possible I will need a fallback plan. The best idea I have come up with so far is to use the various MS sample applications as examples of real world applications. e.g. http://msftdpprodsamples.codeplex.com/ http://www.asp.net/community/projects/ Does anyone have any better suggestions?

  • Anomalous results getting color components of some UIColors

    - by hkatz
    I'm trying to extract the rgb components of a UIColor in order to hand-build the pixels in a CGBitmapContext. The following sample code works fine for most of the UIColor constants but, confusingly, not all. To wit: CGColorRef color = [[UIColor yellowColor] CGColor]; const float* rgba = CGColorGetComponents(color); float r = rgba[0]; float g = rgba[1]; float b = rgba[2]; float a = rgba[3]; NSLog( @"r=%f g=%f b=%f a=%f", r, g, b, a); The results for [UIColor yellowColor] above are r=1.000000 g=1.000000 b=0.000000 a=1.000000, as expected. [UIColor redColor] gives r=1.000000 g=0.000000 b=0.000000 a=1.000000, again as expected. Similarly for blueColor and greenColor. However, the results for [UIColor blackColor] and [UIColor whiteColor] seem completely anomalous, and I don't know what I'm doing wrong (if indeed I am). To wit, [UIColor blackColor] gives r=0.000000 g=1.000000 b=0.000000 a=0.000000, which is a tranparent green, and [UIColor whiteColor] gives r=1.000000 g=1.000000 b=0.000000 a=0.000000, which is a transparent yellow. I'd appreciate it if somebody could either: (1) explain what I'm doing wrong (2) replicate my anomalous results and tell me it's not me, or (3) hit me over the head with a big hammer so it stops hurting so much.

  • SharePoint Visual web part and Oracle connection problem

    - by Rishi
    Hi, I'm trying to build a "visual web part" for SharePoint 2010 which should connect to Oracle table and display records on SharePoint page.For development, Oracle 11g client (with ODP.net) ,SharePoint server 2010, Visual Studio 2010 and Oracle 10g express all running on my machine. First,I've written sample code in ASP.NET web app to connect my local Oracle table and display data in grid view and it works fine. My code is , OracleConnection con; try { // Connect string constr = "Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=XE)));User Id=SYSTEM; Password=password"; con = new OracleConnection(constr); //Open database connection con.Open(); // Execute a SQL SELECT OracleCommand cmd = new OracleCommand("select * from T_ACTIONPOINTS WHERE AP_STATUS='Active' ", con); OracleDataReader dr = cmd.ExecuteReader(); GridView.DataSource = dr; GridView.DataBind(); GridView.AllowPaging = true; } catch (Exception e) { lblError.Text = e.Message; } Now, I'm trying to create new "SharePoint" visual web part project and using same code and deploying it on my local SP server. But when it runs , I get following error here is my solution explorer, It looks something wrong in compatibility.Can someone point me in right direction ?

  • How do i refactor this code by using Action<t> or Func<t> delegates

    - by user330612
    I have a sample program, which needs to execute 3 methods in a particular order. And after executing each method, should do error handling. Now i did this in a normal fashion, w/o using delegates like this. class Program { public static void Main() { MyTest(); } private static bool MyTest() { bool result = true; int m = 2; int temp = 0; try { temp = Function1(m); } catch (Exception e) { Console.WriteLine("Caught exception for function1" + e.Message); result = false; } try { Function2(temp); } catch (Exception e) { Console.WriteLine("Caught exception for function2" + e.Message); result = false; } try { Function3(temp); } catch (Exception e) { Console.WriteLine("Caught exception for function3" + e.Message); result = false; } return result; } public static int Function1(int x) { Console.WriteLine("Sum is calculated"); return x + x; } public static int Function2(int x) { Console.WriteLine("Difference is calculated "); return (x - x); } public static int Function3(int x) { return x * x; } } As you can see, this code looks ugly w/ so many try catch loops, which are all doing the same thing...so i decided that i can use delegates to refactor this code so that Try Catch can be all shoved into one method so that it looks neat. I was looking at some examples online and couldnt figure our if i shud use Action or Func delegates for this. Both look similar but im unable to get a clear idea how to implement this.

  • Sql serve Full Text Search with Containstable is very slow when Used in JOIN!

    - by Bob
    Hello, I am using sql 2008 full text search and I am having serious issues with performance depending on how I use Contains or ContainsTable. Here are sample: (table one has about 5000 records and there is a covered index on table1 which has all the fields in the where clause. I tried to simplify the statements so forgive me if there is syntax issues.) Scenario 1: select * from table1 as t1 where t1.field1=90 and t1.field2='something' and Exists(select top 1 * from containstable(table1,*, 'something') as t2 where t2.[key]=t1.id) results: 10 second (very slow) Scenario 2: select * from table1 as t1 join containstable(table1,*, 'something') as t2 on t2.[key] = t1.id where t1.field1=90 and t1.field2='something' results: 10 second (very slow) Scenario 3: Declare @tbl Table(id uniqueidentifier primary key) insert into @tbl select {key] from containstable(table1,*, 'something') select * from table1 as t1 where t1.field1=90 and t1.field2='something' and Exists(select id from @tbl as tbl where id=req1.id) results: fraction of a second (super fast) Bottom line, it seems if I use Containstable in any kind of join or where clause condition of a select statement that also has other conditions, the performance is really bad. In addition if you look at profiler, the number of reads from the database goes to the roof. But if I first do the full text search and put results in a table variable and use that variable everything goes super fast. The number of reads are also much lower. It seems in "bad" scenarios, somehow it gets stuck in a loop which causes it to read many times from teh database but of course I don't understant why. Now the question is first of all whyis that happening? and question two is that how scalable table variables are? what if it results to 10s of thousands of records? is it still going to be fast. Any ideas? Thanks

  • Adding trend lines/boxplots (by group) in ggplot2

    - by Tal Galili
    Hi all, I have 40 subjects, of two groups, over 15 weeks, with some measured variable (Y). I wish to have a plot where: x = time, y = T, lines are by subjects and colours by groups. I found it can be done like this: TIME <- paste("week",5:20) ID <- 1:40 GROUP <- sample(c("a","b"),length(ID), replace = T) group.id <- data.frame(GROUP, ID) a <- expand.grid(TIME, ID) colnames(a) <-c("TIME", "ID") group.id.time <- merge(a, group.id) Y <- rnorm(dim(group.id.time)[1], mean = ifelse(group.id.time$GROUP =="a",1,3) ) DATA <- cbind(group.id.time, Y) qplot(data = DATA, x=TIME, y=Y, group=ID, geom = c("line"),colour = GROUP) But now I wish to add to the plot something to show the difference between the two groups (for example, a trend line for each group, with some CI shadelines) - how can it be done? I remember once seeing the ggplot2 can (easily) do this with geom_smooth, but I am missing something about how to make it work. Also, I wondered at maybe having the lines be like a boxplot for each group (with a line for the different quantiles and fences and so on). But I imagine answering the first question would help me resolve the second. Thanks.

  • blackberry implement audio player

    - by Prasad
    Hi, I am developing an application which let users to hear songs online. And I used Blackberry Player and Manager APIs. My application works fine and I can play songs. Now I wan't to add more controls to it. As an example I want pause, play songs. Mute the sound, Control the volume. Display the progress of the play back. Display the current time position of the song like that. I started research on that. And I tried to do that with PlayerListener. But unfortunately all the time I am getting IllegalStateException. So I can't go ahead with that research. As a help can someone please tell me how can I implement above kind of controls for a player. Appreciate if someone can post a sample code to do that. Further I will put my playback source code here. public void run() { try { p = Manager.createPlayer(requestedSong + SystemSettings.strNetwork); p.setLoopCount(1); p.start(); } catch (IOException ioe) { } catch (MediaException me) { } } public void run() { try { p = Manager.createPlayer(strSongURL); p.setLoopCount(1); p.start(); } catch (IOException ioe) { } catch (MediaException me) { } } Thank you very much.

  • Symfony fk issue on insertion

    - by Daniel Hertz
    Hi, I posted a similar problem but it could not be resolved. I create a relational database of users and groups but for some reason I cannot insert test data with fixtures properly. Here is a sample of the schema: User: actAs: { Timestampable: ~ } columns: name: { type: string(255), notnull: true } email: { type: string(255), notnull: true, unique: true } nickname: { type: string(255), unique: true } password: { type: string(300), notnull: true } image: { type: string(255) } Group: actAs: { Timestampable: ~ } columns: name: { type: string(500), notnull: true } image: { type: string(255) } type: { type: string(255), notnull: true } created_by_id: { type: integer } relations: User: { onDelete: SET NULL, class: User, local: created_by_id, foreign: id, foreignAlias: groups_created } FanOf: actAs: { Timestampable: ~ } columns: user_id: { type: integer, primary: true } group_id: { type: integer, primary: true } relations: User: { onDelete: CASCADE, local: user_id, foreign: id, foreignAlias: fanhood } Group: { onDelete: CASCADE, local: group_id, foreign: id, foreignAlias: fanhood } And this is the data i try to input: User: user1: name: Danny email: [email protected] nickname: danny password: f05050400c5e586fa6629ef497be Group: group1: name: Mets type: sports FanOf: fans1: user_id: user1 group_id: group1 I keep getting this error: SQLSTATE[23000]: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails (`krowdd`.`fan_of`, CONSTRAINT `fan_of_user_id_user_id` FOREIGN KEY (`user_id`) REFERENCES `user` (`id`) ON DELETE CASCADE) The users and groups are clearly being created before the "fanhood" is so why am I getting this error?? Thanks!
