  • manage.py runserver throws an ImportError with my appname, MacPorts issue on OSX?

    - by christmasgorilla
    I've been developing a Django app for weeks locally on OSX 10.6.3. Recently, I rebooted my machine and went to start my development environment up. Here's the error: cm:myApp cm$ python manage.py runserver Traceback (most recent call last): File "manage.py", line 11, in execute_manager(settings) File "/Library/Python/2.6/site-packages/django/core/management/init.py", line 360, in execute_manager setup_environ(settings_mod) File "/Library/Python/2.6/site-packages/django/core/management/init.py", line 343, in setup_environ project_module = import_module(project_name) File "/Library/Python/2.6/site-packages/django/utils/importlib.py", line 35, in import_module import(name) ImportError: No module named myapp I'm pretty new to Django / Python. Digging around, it's possible that this might be due to MacPorts. Initially, I had a rough time getting Django up and running and I no longer remember if I'm using the Django from a MacPorts install or from easy_install. How do I tell? (I'd prefer not to reinstall everything). Also, why is the camel casing in my app name gone in the ImportError message? When I search for "myapp" in my django project, I don't find it without camelcase anywhere. And what causes MacPorts to work for a while but then break? As a few other details, from settings.py: INSTALLED_APPS = ( 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'django.contrib.admin', 'south', 'registration', 'pypaypal', 'notifier', 'myApp.batches', )

  • Installing Mercurial on Mac OS X 10.6 Snow Leopard

    - by Matthew Rankin
    Installing Mercurial on Mac OS X 10.6 Snow Leopard I installed Mercurial 1.3.1 on Mac OS X 10.6 Snow Leopard from source using the following: cd ~/src curl -O http://mercurial.selenic.com/release/mercurial-1.3.1.tar.gz tar xzvf mercurial-1.3.1.tar.gz cd mercurial-1.3.1 make ALL sudo make install This installs the site-packages files for Mercurial in /usr/local/lib/python2.6/site-packages/. I know that installing Mercurial from the Mac Disk Image will install the files into /Library/Python/2.6/site-packages/, which is the site-packages directory for the Mac OS X default Python install. I have Python 2.6.2+ installed as a Framework with its site-packages directory in: /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages With Mercurial installed this way, I have to issue: PYTHONPATH=/usr/local/lib/python2.6/site-packages:"${PYTHONPATH}" in order to get Mercurial to work. Questions How can I install Mercurial from source with the site-packages in a different directory? Is there an advantage or disadvantage to having the site-packages in the current location? Would it be better in one of the Python site-package directories that already exist? Do I need to be concerned about virtualenv working correctly since I have modified PYTHONPATH (or any other conflicts for that matter)? Reasons for Installing from Source Dan Benjamin of Hivelogic provides the benefits of and instructions for installing Mercurial from source in his article Installing Mercurial on Snow Leopard.

  • IronPython/C# Float data comparison

    - by Gopalakrishnan Subramani
    We have WPF based application using Prism Framework. We have embedded IronPython and using Python Unit Test framework to automate our application GUI testing. It works very well. We have difficulties in comparing two float numbers. Example class MyClass { public object Value { get; set;} public MyClass() { Value = (float) 12.345; } } In IronPython When I compare the MyClass Instance's Value property with python float value(12.345), it says it doesn't equal This statement raises assert error self.assertEqual(myClassInstance.Value, 12.345) This statement works fine. self.assertEqual(float(myClassInstance.Value.ToString()), 12.345) When I check the type of the type(myClassInstance.Value), it returns Single in Python where as type(12.345) returns float. How to handle the C# float to Python comparison without explicit conversions?

  • Is there a way to watch all COM activity on a computer?

    - by Fake Name
    I'm trying to deal with a piece of specialized hardware, that presents it's interface as a COM object, using win32com in Python. However, the documentation for how to actually set up the hardware through the COM object is sparse (it requires a significant amount of initialization), and entirely oriented at using a bunch of pre-built libraries for Visual Studio, which are not accessible through python. That said, is there any way to watch all local COM activity, so I can sort through the activity logs to try and figure out how the existing demo programs properly initialize the hardware, and replicate the behavior in my python script? Ideally, there would be something in the vein of wireshark for doing this. Note: I have very little (read: basically no) experience using COM, as my focus is mostly embedded hardware (and a little python dev on the side). However, I'm stuck with this particular device.

  • Cleaning up temp folder after long-running subprocess exits

    - by dbr
    I have a Python script (running inside another application) which generates a bunch of temporary images. I then use subprocess to launch an application to view these. When the image-viewing process exists, I want to remove the temporary images. I can't do this from Python, as the Python process may have exited before the subprocess completes. I.e I cannot do the following: p = subprocess.Popen(["imgviewer", "/example/image1.jpg", "/example/image1.jpg"]) p.communicate() os.unlink("/example/image1.jpg") os.unlink("/example/image2.jpg") ..as this blocks the main thread, nor could I check for the pid exiting in a thread etc The only solution I can think of means I have to use shell=True, which I would rather avoid: cmd = ['imgviewer'] cmd.append("/example/image2.jpg") for x in cleanup: cmd.extend(["&&", "rm", x]) cmdstr = " ".join(cmd) subprocess.Popen(cmdstr, shell = True) This works, but is hardly elegant, and will fail with filenames containing spaces etc.. Basically, I have a background subprocess, and want to remove the temp files when it exits, even if the Python process no longer exists.

  • Calling COM Library From XBAP

    - by Benny
    I am trying to call an old COM library from my XBAP and continue to receive the following exception: System.AccessViolationException was unhandled Message: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. I have tried adding the HKLM value for RunUnrestricted to no avail. I don't get anything else but this error when calling the library. Any ideas? (This library even works from a pure ASP.NET app)

  • Ubuntu: SWT App Can't Load GTK Library

    - by Nifty255
    I have supplied the Linux SWT jar and packaged my app in Eclipse to include swt.jar inside my app's jar. When I try to run it on Ubuntu, I get the following error text (posting only cause): Caused by: java.lang.UnsatisfiedLinkError: Could not load SWT library. Reasons: no swt-pi-gtk-4234 in java.library.path no swt-pi-gtk in java.library.path /home/nifty/.swt/lib/linux/x86/libswt-pi-gtk-4234.so: libgtk-x11-2.0.so.0: cannot open shared object file: No such file or directory Can't load library: /home/nifty/.swt/lib/linux/x86/libswt-pi-gtk.so This indicates to me it can't load a GTK file, but anything beyond that, and I'm at a loss. I'm only using Ubuntu to test my app, so I know very little.

  • Connection string in app.config in a class library

    - by Copeleto
    I am creating solution and inside I have three projects: A WCF Service Library Project A DataAccess Project (Class Library) A Web site for hosting WCF service The implementation of the service is on the project # 1, but in order to access the DataBase I use a second project that implements the data access using a class library project. That problem is in order to get data access I need to configure a connection string, but that connection string must be configurable in a production environment, I meant in production I am going to deploy the site, which is a very simple project that contains only a reference WCF Service Library Project then a guy from database department will configure the connection string. In development I have an app.config on the data access project but when I do the release that app.config is embedded on the dll. Any ideas how can we achieve our purpose

  • Flex Unit testing of library and mxml using FlexUnit

    - by user344722
    Hi, I have some software classes(library) to run commands on any mxml file. These classes(library) are wrapped in a SWC file. This SWC file is referenced by any sample mxml application (by adding as SWC file). My problem is that I want to test these software classes(library) against my sample mxml file using FlexUnit. That is, I should test methods run by software classes on the mxml file. How can I accomplish this? Thanks, Pradeep

  • pyopengl: Could it replace c++ ?

    - by Tom
    Hi everyone. I'm starting a computer graphics course, and I have to choose a language. Choices are between C++ and Python. I have no problem with C++, python is a work in progress. So i was thinking to go down the python road, using pyopengl for graphics part. I have heard though, that performance is an issue. Is python / pyopengl mature enough to challenge C++ on performance? I realize its a long shot, but I'd like to hear your thoughts, experiences on uses of pyopengl. Thanks in advance.

  • As a newbie, where should I go if I want to create a small GUI program?

    - by jimbmk
    Hello, I'm a newbie with a little experience writing in BASIC, Python and, of all things, a smidgeon of assembler (as part of a videogame ROM hack). I wanted to create small tool for modifying the hex values at particular points, in a particular file, that would have a GUI interface. What I'm looking for is the ability to create small GUI program, that I can distribute as an EXE (or, at least a standalone directory). I'm not keen on the idea of the .NET languages, because I don't want to force people to download a massive .NET framework package. I currently have Python with IDLE and Boa Constructor set up, and the application runs there. I've tried looking up information on compiling a python app that relies on Wxwidgets, but the search results and the information I've found has been confusing, or just completely incomprehensible. My questions are: Is python a good language to use for this sort of project? If I use Py2Exe, will WxWidgets already be included? Or will my users have to somehow install WxWidgets on their machines? Am I right in thinking at Py2Exe just produces a standalone directory, 'dist', that has the necessary files for the user to just double click and run the application? If the program just relies upon Tkinter for GUI stuff, will that be included in the EXE Py2Exe produces? If so, are their any 'visual' GUI builders / IDEs for Python with only Tkinter? Thankyou for your time, JBMK

  • How can I use Django with MySQL in MAMP stack?

    - by Robert A Henru
    Hi all, I have difficulty especially in installing MySQLdb module (MySQL-python-1.2.3c1), to connect to the MySQL in MAMP stack. I've done a number of things such as copying the mysql include directory and library (including plugin) from a fresh installation of mysql (version 5.1.47) to the one inside MAMP (version 5.1.37). Now, the MySQLdb module build and install doesnt give me error. The error happens when I'm calling 'import MySQLdb' from python shell (version 2.6). Traceback (most recent call last): File "<stdin>", line 1, in <module> File "build/bdist.macosx-10.6-universal/egg/MySQLdb/__init__.py", line 19, in <module> File "build/bdist.macosx-10.6-universal/egg/_mysql.py", line 7, in <module> File "build/bdist.macosx-10.6-universal/egg/_mysql.py", line 6, in __bootstrap__ ImportError: dlopen(/Users/rhenru/.python-eggs/MySQL_python-1.2.3c1-py2.6-macosx-10.6-universal.egg-tmp/_mysql.so, 2): Symbol not found: _mysql_affected_rows Referenced from: /Users/rhenru/.python-eggs/MySQL_python-1.2.3c1-py2.6-macosx-10.6-universal.egg-tmp/_mysql.so Expected in: flat namespace in /Users/rhenru/.python-eggs/MySQL_python-1.2.3c1-py2.6-macosx-10.6-universal.egg-tmp/_mysql.so Any idea, what else do I need to do to make it works?

  • iphone sdk conditional in switch function

    - by Oliver
    I'm trying to make a random image appear on the press of a button. So it generates a random number, and the switch algorithm swaps the chosen image with the one in the imgview. but I want a switch in the settings app to toggle which set of images to use. I know pretty much how to do it...it's just that it doesn't work. I'm missing some syntax thing...Please help, stackoverflow? it's my birthday. int Number = rand() %30; NSString *toggleValue = [[NSUserDefaults standardUserDefaults] stringForKey:@"enabled_preference"]; switch (Number) { if (*toggleValue == 0) { case 0: picture.image = [UIImage imageNamed:@"1.png"]; break; case 1: picture.image = [UIImage imageNamed:@"2.png"]; break;} else { case 0: picture.image = [UIImage imageNamed:@"3.png"]; break; case 1: picture.image = [UIImage imageNamed:@"4.png"]; break;} }

  • Automatically deleting pyc files when corresponding py is moved (Mercurial)

    - by Oddthinking
    (I foresaw this problem might happen 3 months ago, and was told to be diligent to avoid it. Yesterday, I was bitten by it, hard, and now that it has cost me real money, I am keen to fix it.) If I move one of my Python source files into another directory, I need to remember to tell Mercurial that it moved (hg move). When I deploy the new software to my server with Mercurial, it carefully deletes the old Python file and creates it in the new directory. However, Mercurial is unaware of the pyc file in the same directory, and leaves it behind. The old pyc is used preferentially over new python file by other modules in the same directory. What ensues is NOT hilarity. How can I persuade Mercurial to automatically delete my old pyc file when I move the python file? Is there another better practice? Trying to remember to delete the pyc file from all the Mercurial repositories isn't working.

  • Framework Similar to Pylons for Ruby

    - by Travis
    I've been using Python for most of my web projects lately, and have come to really love the Pylons MVC framework. I like the incredible transparency (lack of magic), the built-in components they selected (sqlalchemy, formencode, routes), and the ability to easily change things up (use a different ORM or templating engine). Moving forward, due to constraints at my company, I'm going to be trying out Ruby rather than Python. I'm wondering if people with experience in both have any recommendations for a Ruby framework that is comparable to Pylons. Python is to Django as Ruby is to Rails Python is to Pylons as Ruby is to ?

  • how to kill (or avoid) zombie processes with subprocess module

    - by Dave
    When I kick off a python script from within another python script using the subprocess module, a zombie process is created when the subprocess "completes". I am unable to kill this subprocess unless I kill my parent python process. Is there a way to kill the subprocess without killing the parent? I know I can do this by using wait(), but I need to run my script with no_wait().

  • Unit testing an iPhone static library with XCode 3

    I am writing a number of static libraries for the iPhone and wish also to have suites of unit tests. XCode 3 provides templates for both static libraries and unit tests but I am wondering how they should fit together in a static library project? In my static library project I have created a target for unit testing but expect to also create an executable to kick off the unit tests than run against the classes in the static library. What is the procedure for doing this?

  • How to set UCS2 in numpy?

    - by mindcorrosive
    I'm trying to build numpy 1.2.1 as a module for a third-party python interpreter (custom-built, py2.4 linux x86_64) so that I can make calls to numpy from within it. Let's call this one interpreter A. The thing is, the system-wide python interpreter (also py2.4, let's call it B) from the vendor is built with --enable-unicode=ucs4, while the custom one is with UCS2. Needless to say, when I try to build a module with B, I get an error when I try to import numpy in A -- it complains about undefined symbol _PyUnicodeUCS4_IsWhiteSpace. I've searched around and apparently there's no way around this but to compile a custom Python interpreter -- which I did (let's call it interpreter C), properly specifying the unicode string length (verifiable through sys.maxunicode). I managed to build numpy with C as well, surprisingly enough, but still the problem persists when I try to import it in interpreter C. Previously, when I built numpy using B, there were no problems when importing it in B, but A would complain. Perhaps there's an option when building numpy to specify the length of Unicode strings to be used, as when configuring Python builds? Or am I doing something else wrong? A few notes: Upgrading to newer versions of python and/or numpy is not an option - interpreter A will stay on this version of the grammar for the foreseeable future. Also, it is not possible to start the interpreter A in standalone mode to build numpy with it, as it needs some other libraries preloaded I know that this whole thing is a mess, but I'd appreciate any help I can get to make this work. If you need more information, please let me know, I'd be happy to oblige. Thanks to everybody for their time in advance.
