  • What is the best / proper idiom in django for modifying a field during a .save() where you need to o

    - by MDBGuy
    Hi, say I've got: class LogModel(models.Model): message = models.CharField(max_length=512) class Assignment(models.Model): someperson = models.ForeignKey(SomeOtherModel) def save(self, *args, **kwargs): super(Assignment, self).save() old_person = #????? LogModel(message="%s is no longer assigned to %s"%(old_person, self).save() LogModel(message="%s is now assigned to %s"%(self.someperson, self).save() My goal is to save to LogModel some messages about who Assignment was assigned to. Notice that I need to know the old, presave value of this field. I have seen code that suggests, before super().save(), retrieve the instance from the database via primary key and grab the old value from there. This could work, but is a bit messy. In addition, I plan to eventually split this code out of the .save() method via signals - namely pre_save() and post_save(). Trying to use the above logic (Retrieve from the db in pre_save, make the log entry in post_save) seemingly fails here, as pre_save and post_save are two seperate methods. Perhaps in pre_save I can retrieve the old value and stick it on the model as an attribute? I was wondering if there was a common idiom for this. Thanks.

  • Only want "Required field" error to appear ONCE in ASP.NET Validation Summary

    - by PapillonUK
    I have a form with several fields with a RequiredFieldValidator on them. If any of these fields are not filled in I only want the message "Please enter the items marked with an asterisk" to appear once in the ValidationSummary control and an asterisk to appear next to each field. I have done this using the method here. i.e. by setting Text to "*" and ValidationSummary.HeaderText to my message. Great, but no cigar as I also have other fields with other validators e.g. a RegEx for an Email field. This means that if all the required fields are entered but the email is incorrect, the ValidationSummary with "Please enter the items marked with an asterisk" will appear along with the message for the invalid email. Crap! I then tried using a ValidationGroup called "ReqField" and have a one ValidationSummary for this group (with my HeaderText) and another for the other validators, but alas, my Submit button only allows one ValidationGroup to be triggered upon the click event. Does anyone have any ideas as to how I can get this to work? Thanks in adavnce.

  • How to read the network file.

    - by ungalnanban
    I'm using Net::FTP for getting a remote hosted file. I want to read the file. I don't want to get the file from the remote host to my host (localhost), but I need to read the file content only. Is there any module to do this? use strict; use warnings; use Data::Dumper; use Net::FTP; my $ftp = Net::FTP->new("192.168.8.20", Debug => 0) or die "Cannot connect to some.host.name: $@"; $ftp->login("root",'root123') or die "Cannot login ", $ftp->message; $ftp->cwd("SUGUMAR") or die "Cannot change working directory ", $ftp->message; $ftp->get("Testing.txt") or die "get failed ", $ftp->message; $ftp->quit; In the above sample program, I get the file from 192.168.8.20. Then I will read the file and do the operation. I don't want to place the file in my local system. I need to read the Testing.txt file content.

  • C++ MFC server app with sockets crashes and I cannot find the fault, help!

    - by usermeister
    My program has one dialog and two sockets. Both sockets are derived from CAsyncSocket, one is for listening, other is for receiving data from client. My program crashes when client tries to connect to server application and server needs to initialize receiving socket. This is my MFC dialog class. class CFileTransferServerDlg : public CDialog { ... ListeningSocket ListenSock; ReceivingSocket* RecvSock; void OnAccept(); // called when ListenSock gets connection attempt ... }; This is my derived socket class for receiving data that calls parent dialogs method when event is signaled. class ReceivingSocket : public CAsyncSocket { CFileTransferServerDlg* m_pDlg; // for accessing parent dialogs controls virtual void OnReceive(int nErrorCode); } ReceivingSocket::ReceivingSocket() { } This is dialogs function that handles incoming connection attempt when listening socket gets event notification. This is where the crash happens. void CFileTransferServerDlg::OnAccept() { RecvSock = new ReceivingSocket; /* CRASH */ } OR void CFileTransferServerDlg::OnAccept() { ReceivingSocket* tmpSock = new ReceivingSocket; tmpSock->SetParentDlg(this); CString message; if( ListenSock.Accept(*tmpSock) ) /* CRASH */ { message.LoadStringW(IDS_CLIENT_CONNECTED); m_txtStatus.SetWindowTextW(message); RecvSock = tmpSock; } } My program crashes when I try to create a socket for receiving file sent from client application. OnAccept starts when Listening socket signals incoming connection attempt, but my application then crashes. I've tried running it on another computer and connection attempt was succesful. What could be wrong? Error in debug mode: Unhandled exception at 0x009c30e1 in FileTransferServer.exe: 0xC0000005: Access violation reading location 0xccccce58.

  • Unable to save data in database manually and get latest auto increment id, cakePHP

    - by shabby
    I have checked this question as well and this one as well. I am trying to implement the model described in this question. What I want to do is, on the add function of message controller, create a record in thread table(this table only has 1 field which is primary key and auto increment), then take its id and insert it in the message table along with the user id which i already have, and then save it in message_read_state and thread_participant table. This is what I am trying to do in Thread Model: function saveThreadAndGetId(){ //$data= array('Thread' => array()); $data= array('id' => ' '); //Debugger::dump(print_r($data)); $this->save($data); debug('id: '.$this->id); $threadId = $this->getInsertID(); debug($threadId); $threadId = $this->getLastInsertId(); debug($threadId); die(); return $threadId; } $data= array('id' => ' '); This line from the above function adds a row in the thread table, but i am unable to retrieve the id. Is there any way I can get the id, or am I saving it wrongly? Initially I was doing the query thing in the message controller: $this->Thread->query('INSERT INTO threads VALUES();'); but then i found out that lastId function doesnt work on manual queries so i reverted.

  • Does playing a Program from VS2005 cause a program to work any different than the .exe file?

    - by Bryan
    There is a program where I work that works fine when running the .exe file but works differently from expected when opened in VS2005 and played from there. I am therefore asking on here if anyone knows of anything that would work in the .exe file but not the debug from VS? I am not able to post the code for the buttons I'm talking about but I'll try to explain the best I can. There is a receiver hooked up to the computer. When the button is pressed on the program, it shows a message and waits for a signal to be received. After the signal is heard the first message box is supposed to close and another is supposed to open. When using the .exe file this happens just fine. However when playing from the program from VS2005 (the same one from which the .exe was made) the second message doesn't come up when it is supposed to and when I can make it come up, the first box doesn't close. There is also a timer involved if that helps. Also, is there a fundamental difference between how the two operate when executing the program? If I need to make anything more clear or give more details please let me know.

  • Wait set time for user input C#

    - by Marlon
    I need to know how to wait at set amount of time (about 10 seconds), for a user to input a key or set of keys, before proceeding with an 'auto run' portion of the application. This is bugging me because I can't quite figure out how the timer works, or threading.sleep, what should I use? Been googling all day.

    I'd like to have something similar to the following pseudo code: while input is not None and timer < 5: input = getChar() timer = time.time() - start if timer >= 5: print "took too long" else: print input Anyway to do this without threading? I would like an input method that returns whatever has been entered since the last time it was called, or None (null) if nothing was entered.

  • Facebook style messaging system schema design

    - by Jamie
    Hi all, I'm looking to implement a facebook style messaging system (thread messages) into a site of mine. Do you think this schema markup looks okay? Doctrine schema.yml: UserMessage: tableName: user_message actAs: [Timestampable] columns: id: { type: integer(10), primary: true, autoincrement: true } sender_id : { type: integer(10), notnull: true } sender_read: { type: boolean, default: 1 } subject: { type: string(255), notnull: true } message: { type: string(1000), notnull: true } hash: { type: string(32), notnull: true } relations: UserMessageRecipient as Recipient: type: many local: id foreign: message_id UserMessageReply as Reply: type: many local: id foreign: message_id UserMessageReply: tableName: user_message_reply columns: id: { type: integer(10), primary: true, autoincrement: true } user_message_id as message_id: { type: integer(10), notnull: true } message: { type: string(1000), notnull: true } sender_id: { type: integer(10), notnull: true } relations: UserMessage as Message: local: message_id foreign: id type: one UserMessageRecipient: tableName: user_message_recipient actAs: [Timestampable] columns: id: { type: integer(10), primary: true, autoincrement: true } user_message_id as message_id: { type: integer(10), notnull: true } recipient_id: { type: integer(10), notnull: true } recipient_read: { type: boolean, default: 0 } When I a new reply is made,i'll make sure the boolean for "recipient_read" for each recipient is set to false and of course i'll make sure sender_read is set to false too. I'm using a hash for the URL: http://example.com/user/messages/aadeb18f8bdaea49882ec4d2a8a3c062 (As the id will be starting from 1, i don't wish to have http://example.com/user/messages/1. Yeah, I could start incrementing from a bigger number, but i'd prefer to start at 1.) Is this a good way to go about it? Your thoughts and suggestions would be hugely appreciated. Thanks guys!

    - by kandroid
    i want to upload file using jquery dialog. I have created a partial view and showing that partial view in the dialog. The problem is, when I directly browse the partial view and upload a file, it works perfect. BUT when I put the partial view inside a jquery dialog, it submits the form, but don't submits the file. So i have null value. I really dont understand what is the difference here!! Hope someone can help me to identify the problem. here is some codes; jquery codes: $('#UploadDialog').dialog({ autoOpen: false, width: 580, resizable: false, modal: true, open: function (event, ui) { $(this).load('@Url.Action("Upload","Notes")'); }, buttons: { "Upload": function () { $("#upload-message").html(''); $("#noteUploadForm").submit(); }, "Cancel": function () { $(this).dialog("close"); } } }); $(".uploadLink").click(function () { $('#UploadDialog').dialog('open'); }); return false; }); partial view: @using (Ajax.BeginForm("Upload", "Notes", null, new AjaxOptions { UpdateTargetId = "upload-message", InsertionMode = InsertionMode.Replace, HttpMethod = "POST", OnSuccess = "uploadSuccess" }, new { id = "noteUploadForm" , enctype="multipart/form-data"})) { <div> <div id="upload-message"></div> <div class="editLabel"> @Html.LabelFor(m => m.Notes.NoteTitle) </div> <div class="editText"> @Html.TextBoxFor(m => m.Notes.NoteTitle) </div> <div class="clear"></div> <div class="editLabel"> @Html.Label("Upload file") </div> <div class="editText"> <input type="file" name="file" />(100MB max size) </div> </div> }

  • Jquery.Validate plugin + realPerson plugin

    - by Dave Watts
    I can't figure out how to make it so the form wont fire unless the realPerson captcha is "valid". I can see that when the user types in the correct/valid letters and clicks submit it adds a class of "valid" to the input. So Ive been trying to figure out how to get the jquery.validate plugin to only fire when the class "valid" is present. <script type="text/javascript"> $(document).ready(function(){ $('#defaultReal').realperson(); $('#contact_form2').validate({ submitHandler: function(form) { var str = $("form").serialize(); $.ajax({ type: "POST", url: "contactpage.php", data: str, success: function(){ $('#contact_form2').html("<div id='message'></div>"); $('#message').html("<h2>Contact Form Submitted!</h2>") .append("<p>We will be in touch soon.</p>") .hide() .fadeIn(1500, function() { $('#message').append("<img id='checkmark' src='images/check.png' />"); }); }}); return false; } }); Thank you in advanced! -Dave

  • WCF newbie - how to install and use a SSL certificate?

    - by Shaul
    This should be a snap for anyone who's done it before... I'm trying to set up a self-hosted WCF service using NetTcpBinding. I got a trial SSL certificate from Thawte and successfully installed that in my IIS store, and I think I've got it correctly set up in the service - at least it doesn't exception out on me! Now, I'm trying to connect the client (this is still all on my dev machine), and it's giving me an error, "Message = "The X.509 certificate CN=ssl.mydomain.com, OU=For Test Purposes Only. No assurances., OU=IT, O=My Company, L=My Town, S=None, C=IL chain building failed. The certificate that was used has a trust chain that cannot be verified. Replace the certificate or change the certificateValidationMode. A certificate chain processed, but terminated in a root certificate which is not trusted by the trust provider." Ooookeeeey... now what? Client code (I want to do this in code, not app.config): var baseAddress = "localhost"; var factory = new DuplexChannelFactory<IMyWCFService>(new InstanceContext(SiteServer.Instance)); factory.Endpoint.Address = new EndpointAddress("net.tcp://{0}:8000/".Fmt(baseAddress)); var binding = new NetTcpBinding(SecurityMode.Message); binding.Security.Message.ClientCredentialType = MessageCredentialType.UserName; factory.Endpoint.Binding = binding; var u = factory.Credentials.UserName; u.UserName = userName; u.Password = password; return factory.CreateChannel()

  • PHP mail may be filtered out by spam?

    - by Derek
    I am creating a small company, and would like to send out emails to my clients once they have signed up for my service to activate their accounts. I am currently using PHP's mail() function, however I am worried that my emails are being filtered out by spam filters. Is there a better way to go about this? $email = 'XZY Client Email address @ somedomain.com'; $emailSubject = "Welcome to XYZ Service!"; $to = $email; $subject .= "".$emailSubject.""; $headers .= "From: [email protected]\r\n" . "X-Mailer: php"; $headers .= "MIME-Version: 1.0\r\n"; $headers .= "Content-Type: text/html; charset=ISO-8859-1\r\n"; $message = "<html><body>"; $message .= "Welcome to XYZ Service! \n Activate your account by clicking the following link: link..."; mail($to, $subject, $message, $headers); Is there a way to authenticate these emails so that my clients know that they are from my actual service?

  • SQL Group by Minute- Expanded

    - by Barnie
    I am working on something similar to this post here: TS SQL - group by minute However mine is pulling from an message queue, and I need to see an accurate count of the amount of traffic the Message Queue is creating/ sending, and at what time Select * From MessageQueue mq My expanded version of this though is the following: A) User defines a start time and an end time (Easy enough using Declare's @StartTime and @EndTime B) Give the user the option of choosing the "grouping". Will it be broken out by 1 minutes, 5 minutes, 15 minutes, or 30 minutes (Max). (I had thought to do this with a CASE statement, but my test problems fall apart on me.) C) Display the data to accurately show a count of what happened during the interval (Grouping) selected. This is where I am at so far SQL Blob: DECLARE @StartTime datetime DECLARE @EndTime datetime SELECT DATEPART(n, mq.cre_date)/5 as Time --Trying to just sort by 5 minute intervals ,CONVERT(VARCHAR(10),mq.Cre_Date,101) ,COUNT(*) as results FROM dbo.MessageQueue mq WHERE mq.cre_date BETWEEN @StartDate AND @EndDate GROUP BY DATEPART(n, mq.cre_date)/5 --Trying to just sort by 5 minute intervals , eq.Cre_Date This is the output I would like to achieve: [Time] [Date] [Message Count] 1300 06/26/2012 5 1305 06/26/2012 1 1310 06/26/2012 100

  • Achieving C# "readonly" behavior in C++

    - by Tommy Fisk
    Hi guys, this is my first question on stack overflow, so be gentle. Let me first explain the exact behavior I would like to see. If you are familiar with C# then you know that declaring a variable as "readonly" allows a programmer to assign some value to that variable exactly once. Further attempts to modify the variable will result in an error. What I am after: I want to make sure that any and all single-ton classes I define can be predictably instantiated exactly once in my program (more details at the bottom). My approach to realizing my goal is to use extern to declare a global reference to the single-ton (which I will later instantiate at a time I choose. What I have sort of looks like this, namespace Global { extern Singleton& mainInstance; // not defined yet, but it will be later! } int main() { // now that the program has started, go ahead and create the singleton object Singleton& Global::mainInstance = Singleton::GetInstance(); // invalid use of qualified name Global::mainInstance = Singleton::GetInstance(); // doesn't work either :( } class Singleton { /* Some details ommited */ public: Singleton& GetInstance() { static Singleton instance; // exists once for the whole program return instance; } } However this does not really work, and I don't know where to go from here. Some details about what I'm up against: I'm concerned about threading as I am working on code that will deal with game logic while communicating with several third-party processes and other processes I will create. Eventually I would have to implement some kind of synchronization so multiple threads could access the information in the Singleton class without worry. Because I don't know what kinds of optimizations I might like to do, or exactly what threading entails (never done a real project using it), I was thinking that being able to predictably control when Singletons were instantiated would be a Good Thing. Imagine if Process A creates Process B, where B contains several Singletons distributed against multiple files and/or libraries. It could be a real nightmare if I can not reliably ensure the order these singleton objects are instantiated (because they could depend on each other, and calling methods on a NULL object is generally a Bad Thing). If I were in C# I would just use the readonly keyword, but is there any way I can implement this (compiler supported) behavior in C++? Is this even a good idea? Thanks for any feedback.

  • How to get an embedded function to run multiple times

    - by Guy Montag
    The question I have is how to I get multiple instances of a function to run. Here is my function below - A simple fade function. Problem I'm having is that when it is called a second time it abandons the first call. So if a user clicks on a button it will display a message which fades. If the user clicks on another button the previous fading message just stops at the current opacity level. Try it here - www.arcmarks.com ( please do not repost this domain name) click on SignUp and than quickly click on SignIn with out typing anything. You will see the previous message simply halts. ? What is the stopping mechanism? Where did the previous function go? The function function newEffects(element, direction, max_time ) { newEffects.arrayHold = []; newEffects.arrayHold[element.id] = 0; function next() { newEffects.arrayHold[element.id] += 10; if ( direction === 'up' ) { element.style.opacity = newEffects.arrayHold[element.id] / max_time; } else if ( direction === 'down' ) { element.style.opacity = ( max_time - newEffects.arrayHold[element.id] ) / max_time; } if ( newEffects.arrayHold[element.id] <= max_time ) { setTimeout( next, 10 ); } } next(); return true; }; The Call newEffects(this.element, 'down', 4000 );
