  • How much should I rely on Visual Studio's Auto Generated Code?

    - by Ant
    So I'm reading up on ASP.NET with VB.NET and I want to start making my own, professionally built website using ASP. I'm wondering though; I'm still using the basics so I'm really just a novice, but how much should I rely on Visual Studio to create my elements? Should I make my own text boxes and have my own login routine, or should I just use ASP's login features? I know eventually you have to use your own classes and such which is where the real coding comes in, but I'm not sure how relaible, flexible and secure the pre-wrote elements are? Any help would be greatly appreciated.

  • How Visual Studio could help to avoid duplicating code?

    - by MegaMind
    I work within a team of developers. Everyone is making their changes without carrying too much if the same thing is already implemented in the codebase. This leads to classes constantly growing and to severe duplication. I want to add line items to class definitions from which a developer could judge what this class has. Would it help? How to do it in Visual Studio? If it wouldn't help, what would be the better alternative to encourage the developers to check if something exists before implementing it?

  • Révisions : Microsoft met en ligne ses cahiers de pré-rentrée sur Visual Studio 2012, Windows Phone, Windows 8, Azure et Windows Server 2012

    Révision de pré-rentrée : Microsoft a mis en ligne ses cahiers de vacances Sur Visual Studio 2012, Windows Phone, Windows 8, Azure et Windows Server Mea Culpa. Nous aurions pu en parler avant. Mais mieux vaut tard que jamais. D'autant plus que les révisions, c'est bien aussi quand ça ne dure pas toutes les vacances. Quoiqu'il en soit, Microsoft a mis en ligne deux « Cahiers de vacances » pour faire le point, se tester et/ou apprendre à maitrise toutes les nouveautés (et Dieu sait qu'elles sont nombreuses) autour de ses produits. Le premier, « J'en ai rien à déployer », revient sur la RC de Windows Server 2012, et sur la virtualisation av...

  • How to change TXSDateTime SOAP serialization in Delphi 7?

    - by LukLed
    I am trying to use Java based webservice and have soap request: <?xml version="1.0"?> <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"> <SOAP-ENV:Body xmlns:NS1="http://something/"> <NS1:getRequest id="1"> <sessionId xsi:type="xsd:string"></sessionId> <reportType xsi:type="NS1:reportType">ALL</reportType> <xsd:dateFrom xsi:type="xsd:dateTime">2010-05-30T23:29:43.088+02:00</xsd:dateFrom> <xsd:dateTo xsi:type="xsd:dateTime">2010-05-31T23:29:43.728+02:00</xsd:dateTo> </NS1:getRequest> <parameters href="#1" /> </SOAP-ENV:Body> </SOAP-ENV:Envelope> It doesn't work, because webservice doesn't recognize dates as parameters. When I change <xsd:dateFrom xsi:type="xsd:dateTime">2010-05-30T23:29:43.088+02:00</xsd:dateFrom> <xsd:dateTo xsi:type="xsd:dateTime">2010-05-31T23:29:43.728+02:00</xsd:dateTo> to <dateFrom xsi:type="xsd:dateTime">2010-05-30T23:29:43.088+02:00</xsd:dateFrom> <dateTo xsi:type="xsd:dateTime">2010-05-31T23:29:43.728+02:00</xsd:dateTo> everything works ok, but Delphi (without Delphi source code changes) doesn't allow to change generated XML, it has only some options. Is it possible to set conversion options, so TSXDateTime is converted to <dateFrom, not <xsd:dateFrom tag? Did you meet that problem?

    I've having difficulty in populating FullCalendar from MVC and would like a little assistance on the matter please. I have the following code for my controller: Function GetEvents(ByVal [start] As Double, ByVal [end] As Double) As JsonResult Dim sqlConnection As New SqlClient.SqlConnection sqlConnection.ConnectionString = My.Settings.sqlConnection Dim sqlCommand As New SqlClient.SqlCommand sqlCommand.CommandText = "SELECT tripID AS ID, tripName AS Title, DATEDIFF(s, '1970-01-01 00:00:00', dateStart) AS [Start], DATEDIFF(s, '1970-01-01 00:00:00', dateEnd) AS [End] FROM tblTrip WHERE userID=18 AND DateStart IS NOT NULL" sqlCommand.Connection = sqlConnection Dim ds As New DataSet Dim da As New SqlClient.SqlDataAdapter(sqlCommand) da.Fill(ds, "Meetings") sqlConnection.Close() Dim meetings = From c In ds.Tables("Meetings") Select {c.Item("ID"), c.Item("Title"), "False", c.Item("Start"), c.Item("End")} Return Json(meetings.ToArray(), JsonRequestBehavior.AllowGet) End Function This does indeed run correctly but the format that is returned is: [[25,"South America 2008","False",1203033600,1227657600],[48,"Levant 2009","False",1231804800,1233619200],[49,"South America 2009","False",1235433600,1237420800],[50,"Italy 2009","False",1241049600,1256083200],[189,"Levant 2010a","False",1265414400,1267574400],[195,"Levant 2010a","False",1262736000,1262736000],[208,"Levant 2010a","False",1264982400,1267574400],[209,"Levant 2010a","False",1264982400,1265587200],[210,"Levant 2010","False",1264982400,1266969600],[211,"Levant 2010 b","False",1267056000,1267574400],[213,"South America 2010a","False",1268438400,1269648000],[214,"Levant 2010 c","False",1266364800,1264118400],[215,"South America 2010a","False",1268611200,1269648000],[217,"South America 2010","False",1268611200,1269561600],[218,"South America 2010 b","False",1268956800,1269388800],[227,"levant 2010 b","False",1265846400,1266192000]] And this is totally different to what I've seen on the post from here: http://stackoverflow.com/questions/2445359/jquery-fullcalendar-json-date-issue (note the lack of tag information and curly braces) Can someone please explain to me what I may be doing wrong and why my output isn't correctly formatted.

  • Putting WPF Controls into canvas with Visuals

    - by Mikhail
    I am writing a WPF chart and use Visuals for performance. The code looks like: public class DrawingCanvas2 : Canvas { private List<Visual> _visuals = new List<Visual>(); private List<Visual> _hits = new List<Visual>(); protected override Visual GetVisualChild( int index ) { return _visuals[index]; } protected override int VisualChildrenCount { get { return _visuals.Count; } } public void AddVisual( Visual visual ) { _visuals.Add( visual ); base.AddVisualChild( visual ); base.AddLogicalChild( visual ); } } Beside DrawingVisual elements (line, text) I need a ComboBox in the chart. So I tried this: public DrawingCanvas2() { ComboBox box = new ComboBox(); AddVisual( box ); box.Width = 100; box.Height = 30; Canvas.SetLeft( box, 10 ); Canvas.SetTop( box, 10 ); } but it does not work, there is no ComboBox displayed. What I am missing?

Below is the start method for my activator: @Override public void start(BundleContext context) throws Exception { ExecutorService service = Executors.newSingleThreadExecutor(); service.execute(new Runnable() { @Override public void run() { Display display = Display.getDefault(); Shell shell = new Shell(display); Text helloText = new Text(shell, SWT.CENTER); helloText.setText("Hello SWT!"); helloText.pack(); shell.pack(); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); } }); } Calling this code in a Windows environment works fine, but deploying on Mac OS X I get the following output: 2009-10-14 17:17:54.050 java[2010:10003] *** __NSAutoreleaseNoPool(): Object 0x101620d20 of class NSCFString autoreleased with no pool in place - just leaking 2009-10-14 17:17:54.081 java[2010:10003] *** __NSAutoreleaseNoPool(): Object 0x100119240 of class NSCFNumber autoreleased with no pool in place - just leaking 2009-10-14 17:17:54.084 java[2010:10003] *** __NSAutoreleaseNoPool(): Object 0x1001024b0 of class NSCFString autoreleased with no pool in place - just leaking 2009-10-14 17:17:54.086 java[2010:10003] *** __NSAutoreleaseNoPool(): Object 0x7fff701d7f70 of class NSCFString autoreleased with no pool in place - just leaking 2009-10-14 17:17:54.087 java[2010:10003] *** __NSAutoreleaseNoPool(): Object 0x100113330 of class NSCFString autoreleased with no pool in place - just leaking 2009-10-14 17:17:54.092 java[2010:10003] *** __NSAutoreleaseNoPool(): Object 0x101624540 of class NSCFData autoreleased with no pool in place - just leaking . . .

  • Why can't I install MVC (1 or 2) with Visual Web Developer Express 2008 RC1?

    - by Stefan
    Hi all, I have installed VWD 2010 Express and love MVC2. I have an existing ASP.NET 3.5 website that I'd like to redevelop with ASP.NET MVC2 under VWD 2008 with the 3.5 framework (the host only supports .Net 3.5, and Express 2010 doesn't support targeting of .Net framework versions) I am however unable to install MVC2 with VWD 2008. The installer (for 2008 SP1) says it has installed, but the MVC project templates don't show up when I create a new project. I also had this problem originally with MVC1 which is why I gave up at some point and just created it as a normal ASP.NET website. I tried uninstalling and installing VWD 2008, and then installing MVC2, but this didn't solve the problem. Does anyone know why this problem occurs, or how to solve it? Or is there a way to add these templates and the tooling manually?

  • Year split in Quarters using basic jQuery

    - by Alexander Corotchi
    Hi, I have a interesting question: I want to split the year into 4 quarters. What is the idea, A quarter can be different: The HTML Code: <div class="quarterBody"> <span>04-29-2010</span> <span>06-29-2010</span> <span>08-29-2010</span> </div> jQuery (javascript) is total wrong, I hope that w: $(document).ready(function(){ var quarter1 = to make interval (01-01-2010 to 03-31-2010); var quarter2 = to make interval (03-01-2010 to 06-31-2010); var quarter3 = to make interval (06-01-2010 to 09-31-2010); var quarter4 = to make interval (09-01-2010 to 12-31-2010); ... $(".quarterBody span").each(function(){ var date = Date.parse($(this).text()); //to apply some magic code $(this).addClass(quarterNumber); }); }); OUTPUT: <div class="quarterBody"> <span class="Quarter1">02-29-2010</span> <span class="Quarter2">04-29-2010</span> <span class="Quarter3">08-29-2010</span> ... </div> I know right now it is a stupid way, but I hope that somebody can help me, or suggest an idea how to do that in a better way!! Thanks!

  • Processing a log to fix a malformed IP address ?.?.?.x

    - by skymook
    I would like to replace the first character 'x' with the number '7' on every line of a log file using a shell script. Example of the log file: 216.129.119.x [01/Mar/2010:00:25:20 +0100] "GET /etc/.... 74.131.77.x [01/Mar/2010:00:25:37 +0100] "GET /etc/.... 222.168.17.x [01/Mar/2010:00:27:10 +0100] "GET /etc/.... My humble beginnings... #!/bin/bash echo Starting script... cd /Users/me/logs/ gzip -d /Users/me/logs/access.log.gz echo Files unzipped... echo I'm totally lost here to process the log file and save it back to hd... exit 0 Why is the log file IP malformed like this? My web provider (1and1) has decide not to store IP address, so they have replaced the last number with the character 'x'. They told me it was a new requirement by 'law'. I personally think that is bs, but that would take us off topic. I want to process these log files with AWstats, so I need an IP address that is not malformed. I want to replace the x with a 7, like so: 216.129.119.7 [01/Mar/2010:00:25:20 +0100] "GET /etc/.... 74.131.77.7 [01/Mar/2010:00:25:37 +0100] "GET /etc/.... 222.168.17.7 [01/Mar/2010:00:27:10 +0100] "GET /etc/.... Not perfect I know, but least I can process the files, and I can still gain a lot of useful information like country, number of visitors, etc. The log files are 200MB each, so I thought that a shell script is the way to go because I can do that rapidly on my Macbook Pro locally. Unfortunately, I know very little about shell scripting, and my javascript skills are not going to cut it this time. I appreciate your help.

  • Handling asynchronous responses

  • Compiler issues on VC++ 2008 Express, Seemingly correct code throws errors.

    - by Anthony Clever
    Hi there, I've been trying to get back into coding for a while, so I figured I'd start with some simple SDL, now, without the file i/o, this compiles fine, but when I throw in the stdio code, it starts throwing errors. This I'm not sure about, I don't see any problem with the code itself, however, like I said, I might as well be a newbie, and figured I'd come here to get someone with a little more experience with this type of thing to look at it. I guess my question boils down to: "Why doesn't this compile under Microsoft's Visual C++ 2008 Express?" I've attached the error log at the bottom of the code snippet. Thanks in advance for any help. #include "SDL/SDL.h" #include "stdio.h" int main(int argc, char *argv[]) { FILE *stderr; FILE *stdout; stderr = fopen("stderr", "wb"); stdout = fopen("stdout", "wb"); SDL_Init(SDL_INIT_EVERYTHING); fprintf(stdout, "SDL INITIALIZED SUCCESSFULLY\n"); SDL_Quit(); fprintf(stderr, "SDL QUIT.\n"); fclose(stderr); fclose(stdout); return 0; } /* 1>------ Build started: Project: opengl_crap, Configuration: Debug Win32 ------ 1>Compiling... 1>main.cpp 1>c:\documents and settings\owner\my documents\visual studio 2008\projects\opengl_crap\opengl_crap\main.cpp(6) : error C2090: function returns array 1>c:\documents and settings\owner\my documents\visual studio 2008\projects\opengl_crap\opengl_crap\main.cpp(6) : error C2528: '__iob_func' : pointer to reference is illegal 1>c:\documents and settings\owner\my documents\visual studio 2008\projects\opengl_crap\opengl_crap\main.cpp(6) : error C2556: 'FILE ***__iob_func(void)' : overloaded function differs only by return type from 'FILE *__iob_func(void)' 1> c:\program files\microsoft visual studio 9.0\vc\include\stdio.h(132) : see declaration of '__iob_func' 1>c:\documents and settings\owner\my documents\visual studio 2008\projects\opengl_crap\opengl_crap\main.cpp(7) : error C2090: function returns array 1>c:\documents and settings\owner\my documents\visual studio 2008\projects\opengl_crap\opengl_crap\main.cpp(7) : error C2528: '__iob_func' : pointer to reference is illegal 1>c:\documents and settings\owner\my documents\visual studio 2008\projects\opengl_crap\opengl_crap\main.cpp(9) : error C2440: '=' : cannot convert from 'FILE *' to 'FILE ***' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast 1>c:\documents and settings\owner\my documents\visual studio 2008\projects\opengl_crap\opengl_crap\main.cpp(10) : error C2440: '=' : cannot convert from 'FILE *' to 'FILE ***' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast 1>c:\documents and settings\owner\my documents\visual studio 2008\projects\opengl_crap\opengl_crap\main.cpp(13) : error C2664: 'fprintf' : cannot convert parameter 1 from 'FILE ***' to 'FILE *' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast 1>c:\documents and settings\owner\my documents\visual studio 2008\projects\opengl_crap\opengl_crap\main.cpp(15) : error C2664: 'fprintf' : cannot convert parameter 1 from 'FILE ***' to 'FILE *' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast 1>c:\documents and settings\owner\my documents\visual studio 2008\projects\opengl_crap\opengl_crap\main.cpp(17) : error C2664: 'fclose' : cannot convert parameter 1 from 'FILE ***' to 'FILE *' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast 1>c:\documents and settings\owner\my documents\visual studio 2008\projects\opengl_crap\opengl_crap\main.cpp(18) : error C2664: 'fclose' : cannot convert parameter 1 from 'FILE ***' to 'FILE *' 1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast 1>Build log was saved at "file://c:\Documents and Settings\Owner\My Documents\Visual Studio 2008\Projects\opengl_crap\opengl_crap\Debug\BuildLog.htm" 1>opengl_crap - 11 error(s), 0 warning(s) ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ========== */

  • Connection reset when calling disconnect() using enterprisedt's ftp java framework

    - by Frederik Wordenskjold
    I'm having trouble disconnecting from a ftp-server, using the enterprisedt java ftp framework. I can simply not call disconnect() on a FileTransferClient object without getting an error. I do not do anything, besides connecting to the server, and then disconnecting: // create client log.info("Creating FTP client"); ftp = new FileTransferClient(); // set remote host log.info("Setting remote host"); ftp.setRemoteHost(host); ftp.setUserName(username); ftp.setPassword(password); // connect to the server log.info("Connecting to server " + host); ftp.connect(); log.info("Connected and logged in to server " + host); // Shut down client log.info("Quitting client"); ftp.disconnect(); log.info("Example complete"); When running this, the log reads: INFO [test] 28 maj 2010 16:57:20.216 : Creating FTP client INFO [test] 28 maj 2010 16:57:20.263 : Setting remote host INFO [test] 28 maj 2010 16:57:20.263 : Connecting to server x INFO [test] 28 maj 2010 16:57:20.979 : Connected and logged in to server x INFO [test] 28 maj 2010 16:57:20.979 : Quitting client ERROR [FTPControlSocket] 28 maj 2010 16:57:21.026 : Read failed ('' read so far) And the stacktrace: com.enterprisedt.net.ftp.ControlChannelIOException: Connection reset at com.enterprisedt.net.ftp.FTPControlSocket.readLine(FTPControlSocket.java:1029) at com.enterprisedt.net.ftp.FTPControlSocket.readReply(FTPControlSocket.java:1089) at com.enterprisedt.net.ftp.FTPControlSocket.sendCommand(FTPControlSocket.java:988) at com.enterprisedt.net.ftp.FTPClient.quit(FTPClient.java:4044) at com.enterprisedt.net.ftp.FileTransferClient.disconnect(FileTransferClient.java:1034) at test.main(test.java:46) It should be noted, that I without problems can connect, and do stuff with the server, like getting a list of files in the current working directory. But I cant, for some reason, disconnect! I've tried using both active and passive mode. The above example is by the way copy/pasted from their own example. I cannot fint ANYTHING related to this by doing a Google-search, so I was hoping you have any suggestions, or experience with this issue.

  • Why does 12:20 PM parse to 0:20 on the next day?

    - by Hanno Fietz
    I'm using java.text.SimpleDateFormat to parse string representations of date/time values inside an XML document. I'm seeing all times that have an hour value of 12 shifted by 12 hours into the future, i. e. 20 minutes past noon gets parsed to mean 20 minutes past midnight the following day. I wrote a unit test which seems to confirm that the error is made upon parsing (I checked the return values from getTime() with the linux shell command date). Now I'm wondering: is there a bug in the parse() method? is there something wrong with the input string? am I using the wrong format string for the input? The input data is taken from Yahoo's YWeather service. Here's the test and its output: public class YWeatherReaderTest { public static final String[] rgDateSamples = { "Thu, 08 Apr 2010 12:20 PM CEST", "Thu, 08 Apr 2010 12:20 AM CEST" }; public void dateParsing() throws ParseException { DateFormat formatter = new SimpleDateFormat("EEE, dd MMM yyyy K:m a z", Locale.US); for (String dtsSrc : YWeatherReaderTest.rgDateSamples) { Date dt = formatter.parse(dtsSrc); String dtsDst = formatter.format(dt); System.out.println(dtsSrc); System.out.println(dtsDst); System.out.println(); } } } Thu, 08 Apr 2010 12:20 PM CEST Fri, 09 Apr 2010 0:20 AM CEST Thu, 08 Apr 2010 12:20 AM CEST Thu, 08 Apr 2010 0:20 PM CEST The second output line of the second iteration is slightly weird, because 00:20 isn't PM. The milliseconds value of the Date object, however, corresponds to the (wrong) time of 20 minutes past noon.

The problem I have is regarding 2nd item. I use YAJL as it seems to be the faster parser, so why not give it a try :) Here is the part of code that gets the data from the server and parse them: // Get server data response_data = [request responseData]; // Parse JSON received self.arrayFromData = [response_data yajl_JSON]; NSLog(@"Array from data: %@", self.arrayFromData); The parsing works quite well in fact, the NSLog output is something like: 2010-06-14 17:56:35.375 TEST_APP[3733:207] Array from data : { data = ( { val = 1317; date = "2010-06-10T15:50:01+02:00"; }, { val = 1573; date = "2010-06-10T16:20:01+02:00"; }, ........ { val = 840; date = "2010-06-11T14:50:01+02:00"; }, { val = 1265; date = "2010-06-11T15:20:01+02:00"; } ); from = "2010-06-10T15:50:01+02:00"; to = "2010-06-11T15:20:01+02:00"; max = "2590"; } According to th yajl-objc explanations http://github.com/gabriel/yajl-objc, the parsing returns a NSArray... The thing is... I do not know how to get all the values from it as for me it looks more like a NSDictionary than a NSArray... Could you please help ? Thanks a lot, Luc edit1: it happens that this object is actually a NSCFDictionary (!), I am still not able to get value from it, when I try the objectFromKey method (that should work on a Dictionary, no ?) it fails.

  • Putting WPF Control (ComboBox) into canvas with Visuals

    - by Mikhail
    I am writing a WPF chart and use Visuals for performance. The code looks like: public class DrawingCanvas2 : Canvas { private List<Visual> _visuals = new List<Visual>(); protected override Visual GetVisualChild( int index ) { return _visuals[index]; } protected override int VisualChildrenCount { get { return _visuals.Count; } } public void AddVisual( Visual visual ) { _visuals.Add( visual ); base.AddVisualChild( visual ); base.AddLogicalChild( visual ); } } Beside DrawingVisual elements (line, text) I need a ComboBox in the chart. So I tried this: public DrawingCanvas2() { ComboBox box = new ComboBox(); AddVisual( box ); box.Width = 100; box.Height = 30; Canvas.SetLeft( box, 10 ); Canvas.SetTop( box, 10 ); } but it does not work, there is no ComboBox displayed. What I am missing?

  • CentOS: make python 2.6 see django

    - by NP
    In a harrowing attempt to get mod_wsgi to run on CentOS 5.4, I've added python 2.6 as an optional library following the instructions here. The configuration seems fine except that when trying to ping the server the Apache log prints this error: mod_wsgi (pid=20033, process='otalo', application='127.0.0.1|'): Loading WSGI script '...django.wsgi'.

  • Is there a way to customize how the value for a custom Model Field is displayed in a template?

    - by Jordan Reiter
    I am storing dates as an integer field in the format YYYYMMDD, where month or day is optional. I have the following function for formatting the number: def flexibledateformat(value): import datetime, re try: value = str(int(value)) except: return None match = re.match(r'(\d{4})(\d\d)(\d\d)$',str(value)) if match: year_val, month_val, day_val = [int(v) for v in match.groups()] if day_val: return datetime.datetime.strftime(datetime.date(year_val,month_val,day_val),'%b %e, %Y') elif month_val: return datetime.datetime.strftime(datetime.date(year_val,month_val,1),'%B %Y') else: return str(year_val) Which results in the following outputs: >>> flexibledateformat(20100415) 'Apr 15, 2010' >>> flexibledateformat(20100400) 'April 2010' >>> flexibledateformat(20100000) '2010' So I'm wondering if there's a function I can add under the model field class that would automatically call flexibledateformat. So if there's a record r = DataRecord(name='foo',date=20100400) when processed in the form the value would be 20100400 but when output in a template using {{ r.date }} it shows up as "April 2010". Further clarification I do normally use datetime for storing date/time values. In this specific case, I need to record non-specific dates: "x happened in 2009", "y happened sometime in June 1996". The easiest way to do this while still preserving most of the functionality of a date field, including sorting and filtering, is by using an integer in the format of yyyymmdd. That is why I am using an IntegerField instead of a DateTimeField. This is what I would like to happen: I store what I call a "Flexible Date" in a FlexibleDateField as an integer with the format yyyymmdd. I render a form that includes a FlexibleDateField, and the value remains an integer so that functions necessary for validating it and rendering it in widgets work correctly. I call it in a template, as in {{ object.flexibledate }} and it is formatted according to the flexibledateformat rules: 20100416 - April 16, 2010; 20100400 - April 2010; 20100000 - 2010. This also applies when I'm not calling it directly, such as when it's used as a header in admin (http://example.org/admin/app_name/model_name/). I'm not aware if these specific things are possible.

  • Rails nested models and data separation by scope

    - by jobrahms
    I have Teacher, Student, and Parent models that all belong to User. This is so that a Teacher can create Students and Parents that can or cannot log into the app depending on the teacher's preference. Student and Parent both accept nested attributes for User so a Student and User object can be created in the same form. All four models also belong to Studio so I can do data separation by scope. The current studio is set in application_controller.rb by looking up the current subdomain. In my students controller (all of my controllers, actually) I'm using @studio.students.new instead of Student.new, etc, to scope the new student to the correct studio, and therefore the correct subdomain. However, the nested User does not pick up the studio from its parent - it gets set to nil. I was thinking that I could do something like params[:student][:user_attributes][:studio_id] = @student.studio.id in the controller, but that would require doing attr_accessible :studio_id in User, which would be bad. How can I make sure that the nested User picks up the same scope that the Student model gets when it's created? student.rb class Student < ActiveRecord::Base belongs_to :studio belongs_to :user, :dependent => :destroy attr_accessible :user_attributes accepts_nested_attributes_for :user, :reject_if => :all_blank end students_controller.rb def create @student = @studio.students.new @student.attributes = params[:student] if @student.save redirect_to @student, :notice => "Successfully created student." else render :action => 'new' end end user.rb class User < ActiveRecord::Base belongs_to :studio accepts_nested_attributes_for :studio attr_accessible :email, :password, :password_confirmation, :remember_me, :studio_attributes devise :invitable, :database_authenticatable, :recoverable, :rememberable, :trackable end

  • Conditionally Summing the same Column multiple times in a single select statement?

    - by btollett
    I have a single table that shows employee deployments, for various types of deployment, in a given location for each month: ID | Location_ID | Date | NumEmployees | DeploymentType_ID As an example, a few records might be: 1 | L1 | 12/2010 | 7 | 1 (=Permanent) 2 | L1 | 12/2010 | 2 | 2 (=Temp) 3 | L1 | 12/2010 | 1 | 3 (=Support) 4 | L1 | 01/2011 | 4 | 1 5 | L1 | 01/2011 | 2 | 2 6 | L1 | 01/2011 | 1 | 3 7 | L2 | 12/2010 | 6 | 1 8 | L2 | 01/2011 | 6 | 1 9 | L2 | 12/2010 | 3 | 2 What I need to do is sum the various types of people by date, such that the results look something like this: Date | Total Perm | Total Temp | Total Supp 12/2010 | 13 | 5 | 1 01/2011 | 10 | 2 | 1 Currently, I've created a separate query for each deployment type that looks like this: SELECT Date, SUM(NumEmployees) AS "Total Permanent" FROM tblDeployment WHERE DeploymentType_ID=1 GROUP BY Date; We'll call that query qSumPermDeployments. Then, I'm using a couple of joins to combine the queries: SELECT qSumPermDeployments.Date, qSumPermDeployments.["Total Permanent"] AS "Permanent" qSumTempDeployments.["Total Temp"] AS "Temp" qSumSupportDeployments.["Total Support"] AS Support FROM (qSumPermDeployments LEFT JOIN qSumTempDeployments ON qSumPermDeployments.Date = qSumTempDeployments.Date) LEFT JOIN qSumSupportDeployments ON qSumPermDeployments.Date = qSumSupportDeployments.Date; Note that I'm currently constructing that final query under the assumption that a location will only have temp or support employees if they also have permanent employees. Thus, I can create the joins using the permanent employee results as the base table. Given all of the data I currently have, that assumption holds up, but ideally I'd like to move away from that assumption. So finally, my question. Is there a way to simplify this down to a single query or is it best to separate it out into multiple queries - if for no other reason that readability.

  • What could cause these Apache crash errors ?

    - by jacobanderssen
    Hello guys. I had a server crash several days ago. I use Cacti to keep stats: at the time when the server crashed, a huge spike from Load 1 to Load 200 occurred, with over 800 processes in the run queue ( from 300 average). Upon checking /var/log/httpd I notice this: * glibc detected /usr/sbin/httpd: double free or corruption (out): 0x00002b8f3142c2f0 ** Followed by alot of these: [Sat Mar 13 19:20:20 2010] [warn] child process 3090 still did not exit, sending a SIGTERM [Sat Mar 13 19:20:20 2010] [warn] child process 3091 still did not exit, sending a SIGTERM Followed by this: ======= Backtrace: ========= /lib64/libc.so.6[0x2b8f1463c2ef] /lib64/libc.so.6(cfree+0x4b)[0x2b8f1463c73b] /usr/lib64/libapr-1.so.0(apr_pool_destroy+0x131)[0x2b8f13f98821] /usr/sbin/httpd[0x2b8f126df47e] /usr/sbin/httpd[0x2b8f126df4ab] /lib64/libpthread.so.0[0x2b8f141b87c0] /etc/httpd/modules/mod_file_cache.so[0x2b8f1cdf00fb] ======= Memory map: ======== And finally a lot of these: [Sat Mar 13 19:20:27 2010] [error] could not make child process 733 exit, attempting to continue anyway [Sat Mar 13 19:20:27 2010] [error] could not make child process 24560 exit, attempting to continue anyway [Sat Mar 13 19:20:27 2010] [error] could not make child process 31384 exit, attempting to continue anyway I am also noticing one or two lines like this: [Mon Mar 15 01:17:26 2010] [notice] child pid 20765 exit signal Segmentation fault (11) Please help me shed some light on this.

  • LuaEdit can't find module when Lua files all in the same folder

    - by joverboard
    I downloaded LuaEdit to use as an IDE and debug tool however I'm having trouble using it for even the simplest things. I've created a solution with 2 files in it, all of which are stored in the same folder. My files are as follows: --startup.lua require("foo") test("Testing", "testing", "one, two, three") --foo.lua foo = {} print("In foo.lua") function test(a,b,c) print(a,b,c) end This works fine when in my C++ compiler when accessed through some embed code, however when I attempt to use the same code in LuaEdit, it crashes on line 3 require("foo") with an error stating: module 'foo' not found: no field package.preload['foo'] no file 'C:\Program Files (x86)\LuaEdit 2010\lua\foo.lua' no file 'C:\Program Files (x86)\LuaEdit 2010\lua\foo\init.lua' no file 'C:\Program Files (x86)\LuaEdit 2010\foo.lua' no file 'C:\Program Files (x86)\LuaEdit 2010\foo\init.lua' no file '.\foo.lua' no file 'C:\Program Files (x86)\LuaEdit 2010\foo.dll' no file 'C:\Program Files (x86)\LuaEdit 2010\loadall.dll' no file '.\battle.dll' I have also tried creating these files prior to adding them to a solution and still get the same error. Is there some setting I'm missing? It would be great to have an IDE/debugger but it's useless to me if it can't run linked functions.
