  • Webfaction apache + mod_wsgi + django configuration issue

    - by Dmitry Guyvoronsky
    A problem that I stumbled upon recently, and, even though I solved it, I would like to hear your opinion of what correct/simple/adopted solution would be. I'm developing website using Django + python. When I run it on local machine with "python manage.py runserver", local address is http://127.0.0.1:8000/ by default. However, on production server my app has other url, with path - like "http://server.name/myproj/" I need to generate and use permanent urls. If I'm using {% url view params %}, I'm getting paths that are relative to / , since my urls.py contains this urlpatterns = patterns('', (r'^(\d+)?$', 'myproj.myapp.views.index'), (r'^img/(.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT + '/img' }), (r'^css/(.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT + '/css' }), ) So far, I see 2 solutions: modify urls.py, include '/myproj/' in case of production run use request.build_absolute_uri() for creating link in views.py or pass some variable with 'hostname:port/path' in templates Are there prettier ways to deal with this problem? Thank you. Update: Well, the problem seems to be not in django, but in webfaction way to configure wsgi. Apache configuration for application with URL "hostname.com/myapp" contains the following line WSGIScriptAlias / /home/dreamiurg/webapps/pinfont/myproject.wsgi So, SCRIPT_NAME is empty, and the only solution I see is to get to mod_python or serve my application from root. Any ideas?

  • Global resources can't be resolved after publishing Website in VS2008

    - by Scoregraphic
    Hi there I have a web-project running in VS 2008. We have some global resource files (*.resx) in the App_GlobalResources folder for internationalisation. All this works like a charm on my local IIS installation out of VS. But when I publish my web-project to the local filesystem and/or another server, all the resources can no longer be found. So I guess the pre-compilation is somehow corrupting stuff. When I call the pre-compiled web, I get an error that the resource object with key xyz cannot be found, although it could be found before. I checked with .NET reflector if the resource stuff made it into the *.dlls. All those identifiers are there (bin/Web.dll, bin/<culture>/Web.resources.dll). The identifiers are loaded like this: <asp:MenuItem NavigateUrl="~/OrderNew.aspx" Text="<%$ Resources:MyProject, MenuNewOrder %>" Value="NewOrder"> The resource files are called MyProject.resx and MyProject.<culture>.resx where <culture> corresponds the the specific culture (i.e. MyProject.de-DE.resx). Any ideas how to solve this? I really appreciate any help. Thanks Edit: If I copy the App_GlobalResources folder manually to the output, the resources may be loaded normally. So I really really wonder what this pre-compilation is all about. I'm still interested in solving the issue "the right way".

  • Search for content in functions with regex

    - by Marlun
    Hello, How would I with regular expression search for functions which contains the use of a global variable without running "global $var" first? The files looks like this: class TestClass { function correctFunc() { global $var; $name = $var->name; } function invalidFuncIWantToFind() { $age = $var->user->age; } } I want to find the function names of all the invalidFuncIWantToFind. At work this would have really speeded up our work but I didn't get how to do it.

  • First could access the repository next cannot

    - by Banani
    Hi! I have configured svnserve (1.6.5,plain, without apache) on Fedora 12. I could ran the following svn subcommands which access the repository after configuration. Such as, commit, update,checkout, list. But, when next time ( after stopping,ctrl-c and then starting svnserve)I tried above commands, could not access the repository. This is happening both from local and remote machine. I ran svn and svnserve as below. 'svn commit svn://127.0.0.1/myrepository/' from local client. 'svnserve -d --foregorund --listen-port=3690 -r /path-to-repository/mypository/' To understand the problem better, I created another repository and found similar behavior . Frist I could access the repository and next I could not. I tried doing strace on svnserve, but don't uderstand much of it. Below is the partial output. accept(3, {sa_family=AF_INET, sin_port=htons(54425), sin_addr=inet_addr("127.0.0 .1")}, [16]) = 4 fcntl64(4, F_GETFD) = 0 fcntl64(4, F_SETFD, FD_CLOEXEC) = 0 waitpid(-1, 0xbfcdf31c, WNOHANG|WSTOPPED) = -1 ECHILD (No child processes) clone(child_stack=0, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, chil d_tidptr=0xb7743758) = 9737 close(4) = 0 accept(3, 0xbfcdf2bc, [128]) = ? ERESTARTSYS (To be restarted) --- SIGCHLD (Child exited) @ 0 (0) --- sigreturn() = ? (mask now []) waitpid(-1, [{WIFEXITED(s) && WEXITSTATUS(s) == 0}], WNOHANG|WSTOPPED) = 9737 waitpid(-1, 0xbfcdf31c, WNOHANG|WSTOPPED) = -1 ECHILD (No child processes) My question: Why user are not able to access the repository anymore? What information the strace output gives about this problem? Any help is much appreciated. Thanks. Banani

  • Refactoring many nested ifs or chained if statements

    - by Icarus
    Hi, I have an object with large number of similar fields (like more than 10 of them) and I have to assign them values from an array of variable length. The solution would be either a huge nested bunch of ifs based on checking length of array each time and assigning each field OR a chain of ifs checking on whether the length is out of bounds and assigning each time after that check. Both seem to be repetitive. Is there a better solution ?

  • Issue binding Image Source dependency property

    - by Archana R
    Hello, I have created a custom control for ImageButton as <Style TargetType="{x:Type Button}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type Local:ImageButton}"> <StackPanel Height="Auto" Orientation="Horizontal"> <Image Margin="0,0,3,0" Source="{Binding ImageSource}" /> <TextBlock Text="{TemplateBinding Content}" /> </StackPanel> </ControlTemplate> </Setter.Value> </Setter> </Style> ImageButton class looks like public class ImageButton : Button { public ImageButton() : base() { } public ImageSource ImageSource { get { return base.GetValue(ImageSourceProperty) as ImageSource; } set { base.SetValue(ImageSourceProperty, value); } } public static readonly DependencyProperty ImageSourceProperty = DependencyProperty.Register("Source", typeof(ImageSource), typeof(ImageButton)); } However I'm not able to bind the ImageSource to the image as: (This code is in UI Folder and image is in Resource folder) <Local:ImageButton x:Name="buttonBrowse1" Width="100" Margin="10,0,10,0" Content="Browse ..." ImageSource="../Resources/BrowseFolder.bmp"/> But if i take a simple image it gets displayed if same source is specified. Can anyone tell me what shall be done?

  • using a database and deploying the application

    - by evan
    I have a WPF application that stores a large amount of information in XML files and as the user uses the application they add more information to the XML files. It's basically using the XML files as a database. Since over the life of the program the XML files have gotten quite large, and I've been think about putting the data on a website, I've been looking into how to move all the information into an SQL database. I've used SQL databases with web applications (PHP, Ruby, and ASP.NET) but never with a Desktop application. Ideally I'd like to be able to keep all the information in one database file and distribute it along with the application without requiring the user to connect to a remote database (so they don't need an internet connection - though eventually it would be nice if could compare the local file's version with one online somewhere and update if necessary) and without making them install a local database server on their computer. Is this possible? I'd also like to use LINQ with any new database solution so switching to a database doesn't force to many changes (I read the XML with LINQ). I'm sure this question has been asked and that there are already some good tutorials on the subject but I just can't find them.

  • How to camelcase decibels?

    - by Roddy
    The standard abbreviations for decibels is "dB" (note the case!) So, if I have a variable, holding (for instance) a maximum dB value, how best to name it? maxDbValue maxdBValue maxDecibelValue something else? Each has disdvantages - #1 swaps the case of the unit, #2 doesn't clearly split max from dB, and #3 is verbose... I think #1 feels best, but...???

  • Keyword Selection Background?

    - by Irwin
    I just installed MSVS2010 Ultimate & I've noticed something which is somewhat annoying & conflicting with my syntax highlighting, as can be seen: As can be seen, when a keyword/function/variable/etc is highlighted all other instances of the aforementioned are highlighted too. This is somewhat annoying. Is there any way to disable this?

  • Debugging a Google Web Toolkit application that has an error when deployed on Google App Engine

    - by gerdemb
    I have a Google Web Toolkit application that I am deploying to Google App Engine. In the deployed application, I am getting a JavaScript error Uncaught TypeError: Cannot read property 'f' of null. This sounds like the JavaScript equivalent of a Java NullPointerException. The problem is that the GWT JavaScript is obfuscated, so it's impossible to debug in the browser and I can't reproduce the same problem in hosted mode where I could use the Java debugger. I think the reason I'm only seeing the error on the deployed application is that the database I'm using on the GAE server is triggering something differently than the test database I'm using during testing and development. So, any ideas about the best way to proceed? I've thought of the following things: Deploy a non-obsfucated version of my application. Despite a lot of Googling, I can't figure out how to do this using the automatic deploy script provided with the Google Eclipse Plugin. Does anyone know? Download and copy my GAE data to the local server Somehow point my development code to use the GAE server for data instead of the local test database. This seems like the best idea... Can anyone suggest how to proceed here? Finally, is there a way to catch these JavaScript errors on the production server and log them somewhere? Without logging, I won't have anyway to know if my users are having errors that don't occur on the server. The GWT.log() function is automatically stripped out of the production code...

  • pthread and child process data sharing in C

    - by mustafabattal
    hi everyone, my question is somewhat conceptual, how is parent process' data shared with child process created by a "fork()" call or with a thread created by "pthread_create()" for example, are global variables directly passed into child process and if so, does modification on that variable made by child process effect value of it in parent process? i appreciate partial and complete answers in advance, if i'm missing any existing resource, i'm sorry, i've done some search on google but couldn't find good results thanks again for your time and answers

    I'm not quite sure why I can't do double a = (float) my_Function(45) / 2048 / 2340 / 90; printf("%.4",a); // prints out 0.00 But instead I have to use one more variable as: double a = (float) my_Function(45); double b = (float) a / 2048 / 2340 / 90; printf("%.4",b); // prints out the correct value

  • Why does adding Crossover to my Genetic Algorithm give me worse results?

    - by MahlerFive
    I have implemented a Genetic Algorithm to solve the Traveling Salesman Problem (TSP). When I use only mutation, I find better solutions than when I add in crossover. I know that normal crossover methods do not work for TSP, so I implemented both the Ordered Crossover and the PMX Crossover methods, and both suffer from bad results. Here are the other parameters I'm using: Mutation: Single Swap Mutation or Inverted Subsequence Mutation (as described by Tiendil here) with mutation rates tested between 1% and 25%. Selection: Roulette Wheel Selection Fitness function: 1 / distance of tour Population size: Tested 100, 200, 500, I also run the GA 5 times so that I have a variety of starting populations. Stop Condition: 2500 generations With the same dataset of 26 points, I usually get results of about 500-600 distance using purely mutation with high mutation rates. When adding crossover my results are usually in the 800 distance range. The other confusing thing is that I have also implemented a very simple Hill-Climbing algorithm to solve the problem and when I run that 1000 times (faster than running the GA 5 times) I get results around 410-450 distance, and I would expect to get better results using a GA. Any ideas as to why my GA performing worse when I add crossover? And why is it performing much worse than a simple Hill-Climb algorithm which should get stuck on local maxima as it has no way of exploring once it finds a local max?

  • Javascript new object (function ) vs inline invocation

    - by Sheldon Ross
    Is there any considerations to determine which is better practice for creating an object with private members? var object = new function () { var private = "private variable"; return { method : function () { ..dosomething with private; } } } VS var object = function () { ... }(); Basically what is the difference between using NEW here, and just invoking the function immediately after we define it?

  • Auto-Completion in Unix VI editor

    - by IllustratedInsomnia
    Hey guys, after using graphical IDE's like Visual Studio, I'm used to pressing CTRL+Space to auto-complete a variable or function name. Now, I know such a thing isn't completely possible in VI, but I heard there was a list of commands that could be mapped that allowed automatic completion of variables and functions in the current file opened. Does anyone know what this sequence is? Thanks in advance.
